Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

Summary
The current and planned size and composition of the Navy, the annual rate of Navy ship
procurement, the prospective affordability of the Navy’s shipbuilding plans, and the capacity of
the U.S. shipbuilding industry to execute the Navy’s shipbuilding plans have been oversight
matters for the congressional defense committees for many years.
In December 2016, the Navy released a force-structure goal that cal s for achieving and
maintaining a fleet of 355 ships of certain types and numbers. The 355-ship goal was made U.S.
policy by Section 1025 of the FY2018 National Defense Authorization Act (H.R. 2810/P.L. 115-
91 of December 12, 2017). The Navy and the Department of Defense (DOD) have been working
since 2019 to develop a successor for the 355-ship force-level goal. The new goal is expected to
introduce a new, more distributed fleet architecture featuring a smal er proportion of larger ships,
a larger proportion of smal er ships, and a new third tier of large unmanned vehicles (UVs).
On December 9, 2020, the Trump Administration released a document that can be viewed as its
own vision for future Navy force structure. The document presents an envisioned Navy force-
level goal for achieving by 2045 a Navy with a more distributed fleet architecture, including 382
to 446 manned ships and 143 to 242 large UVs. The Biden Administration can choose to adopt,
revise, or set aside this document.
The Navy’s proposed FY2022 budget requests the procurement of eight new ships, including two
Virginia-class attack submarines (SSNs); one Arleigh Burke (DDG-51) class destroyer; one
Constel ation (FFG-62) class frigate; one John Lewis (TAO-205) class oiler; two TATS towing,
salvage, and rescue ships; and one TAGOS(X) ocean surveil ance ship. The total of eight new
ships requested for FY2022 is one more than the total of seven new ships that were projected for
FY2022 under the Navy’s FY2021 budget submission, about two less than steady-state
replacement rate for a 355-ship Navy (which is about 10 ships per year), and four less than the 12
new ships shown in the Trump Administration’s December 9, 2020, shipbuilding document. (One
of the 12 ships shown in the December 9, 2020, document—an LHA amphibious assault ship—is
a ship that, based on congressional action on the Navy’s FY2020 and FY2021 budgets, is treated
in CRS reports as a ship that was procured in FY2021. Excluding this ship from those shown for
FY2022 would reduce the total in the December 9, 2020, document to 11 new ships.)
The Navy’s proposed FY2022 budget requests $18.1 bil ion for construction of new ships within
its shipbuilding budget (the Shipbuilding and Conversion, Navy, or SCN, appropriation account),
compared with $17.8 bil ion for construction of new ships within the SCN account projected for
FY2022 under the Navy’s FY2021 budget submission, $22.8 bil ion in FY2022 for construction
of new ships within the SCN account in the December 9, 2020, document, and an enacted
FY2021 total of $20.1 bil ion for the construction of new ships within the SCN account.
The issue for Congress is whether to approve, reject, or modify the Navy’s force-level goal, its
proposed FY2022 shipbuilding program, and its longer-term shipbuilding plans. Key questions
for Congress include the following: Is the Navy’s force-level goal (either the existing 355-ship
goal or a possible successor goal) appropriate for supporting U.S. national security strategy and
U.S. defense strategy? Is the more distributed fleet architecture envisioned by the Navy the most
cost effective fleet architecture for meeting future mission needs? Are the Navy’s proposed
FY2022 shipbuilding program and (if submitted) its FY2022 five-year and 30-year shipbuilding
plans consistent with the Navy’s force-level goal? Given finite defense resources and competing
demands for defense funds, what is the prospective affordability of the Navy’s shipbuilding
plans? Does the U.S. shipbuilding industry, including both shipyards and supplier firms, have
adequate capacity for executing the Navy’s shipbuilding plans?

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

Introduction
Issue for Congress
This report presents background information and issues for Congress concerning the Navy’s force
structure and shipbuilding plans. The current and planned size and composition of the Navy, the
annual rate of Navy ship procurement, the prospective affordability of the Navy’s shipbuilding
plans, and the capacity of the U.S. shipbuilding industry to execute the Navy’s shipbuilding plans
have been oversight matters for the congressional defense committees for many years.
The issue for Congress is whether to approve, reject, or modify the Navy’s force-level goal, its
proposed FY2022 shipbuilding program, and its longer-term shipbuilding plans. Decisions that
Congress makes on this issue can substantial y affect Navy capabilities and funding requirements
and the U.S. shipbuilding industrial base.

355-Ship Fleet Is a Goal to Be Attained in the Future
The 355-ship fleet is a goal to be attained in the future. As shown in Table G-1, the actual size of
the Navy in recent years has general y been between 270 and 300 ships. Increasing the numerical
size of the Navy from 300 ships to 355 would equate to an increase of about 18%.
355-Ship Goal Made U.S. Policy by FY2018 NDAA
Congress made the 355-ship goal U.S. policy via Section 1025 of the FY2018 National Defense
Authorization Act, or NDAA (H.R. 2810/P.L. 115-91 of December 12, 2017).2

2 Section 1025 of P.L. 115-91 states
SEC. 1025. Policy of the United States on minimum number of battle force ships.
(a) Policy.—It shall be the policy of the United States to have available, as soon as practicable, not
fewer than 355 battle force ships, comprised of the optimal mix of platforms, with funding subject
to the availability of appropriations or other funds.
(b) Battle force ships defined.—In this section, the term “ battle force ship” has the meaning given
the term in Secretary of the Navy Instruction 5030.8C.

355-Ship Goal Resulted from a Force Structure Assessment (FSA) Done in 2016
The 355-ship force-level goal is the result of a Force Structure Assessment (FSA) conducted by
the Navy in 2016. An FSA is an analysis in which the Navy solicits inputs from U.S. regional
combatant commanders (CCDRs) regarding the types and amounts of Navy capabilities that
CCDRs deem necessary for implementing the Navy’s portion of the national military strategy,
and then translates those CCDR inputs into required numbers of ships, using current and
projected Navy ship types. The analysis takes into account Navy capabilities for both warfighting
and day-to-day forward-deployed presence.3
The Navy conducts a new FSA or an update to the existing FSA every few years, as
circumstances require, to determine its force-level goal. Previous Navy force-level goals that
resulted from earlier FSA are shown in Appendix A.
Navy’s Force-Level Goal Is Not Just a Single Number
Although the result of an FSA is often reduced for convenience to single number (e.g., 355 ships),
FSAs take into account a number of factors, including types and capabilities of Navy ships,
aircraft, unmanned vehicles, and weapons, as wel as ship homeporting arrangements and
operational cycles. Thus, although the number of ships cal ed for by an FSA might appear to be a
one-dimensional figure, it actual y incorporates multiple aspects of Navy capability and capacity.
355-Ship Figure Includes Only Manned Ships
The 355-ship force-level goal, like previous Navy force-level goals, is a figure for manned ships
only. The Navy has operated smal er unmanned surface vehicles (USVs) and unmanned
underwater vehicles (UUVs) for many years, but because these unmanned vehicles (UVs) are
launched from manned ships to act essential y as extensions of the manned ships, they have not
been considered ships in their own right and consequently have not been included in the top-level
expression of the Navy’s force-level goal or the publicly cited figure for the number of ships in
the Navy.
Navy’s Next Force-Level Goal Might Include Large Unmanned Vehicles (UVs)
In the years since the 2016 FSA, the Navy has developed plans to acquire large USVs and UUVs.
Because of their size and projected capabilities, these large UVs are to be deployed directly from
pier, rather than from manned ships, to perform missions that might otherwise be assigned to
manned ships and submarines.4 In view of this, some observers have raised a question as to
whether these large UVs should be included in the top-level expression of the Navy’s next force-
level goal (see next section) and the publicly cited figure for the number of ships in the Navy.
Department of Defense (DOD) officials since late 2019 have sent mixed signals on this question,

T he term battle force ships in the above provision refers to the ships that count toward the quoted size of the Navy in
public policy discussions about the Navy. T he battle force ships method for counting the number of ships in the Navy
was established in 1981 by agreement between the Secretary of the Navy and the Secretary of Defe nse, and has been
modified somewhat over time, in part by Section 1021 of the Carl Levin and Howard P. “Buck” McKeon National
Defense Authorization Act for Fiscal Year 2015 (H.R. 3979/P.L. 113-291 of December 19, 2014).
3 For further discussion, see U.S. Navy, Executive Summary, 2016 Navy Force Structure Assessment (FSA), December
15, 2016, pp. 1-2.

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

but September 2020 indicated that the Navy’s next force-level goal (see next section) wil include
large UVs.5
Navy’s Next Force-Level Goal
Work on Navy’s Next Force-Level Goal Underway Since 2019
The Navy and DOD since 2019 have been working to develop a new force-level goal to replace
the current 355-ship force-level goal. The conclusion of this work and the release of its results to
Congress have been delayed repeatedly since late-2019.
Next Navy Force-Level Goal Will Introduce More Distributed Fleet Architecture
Remarks from Navy and DOD officials since 2019 have indicated that the Navy’s next force-
level goal wil introduce a once-in-a-generation change in fleet architecture, meaning basic the
types of ships that make up the Navy and how these ships are used in combination with one
another to perform Navy missions. This new fleet architecture is to be more distributed than the
fleet architecture reflected in the 355-ship goal or previous Navy force-level goals. In particular,
the new fleet architecture is expected to feature
 a smal er proportion of larger ships (such as large-deck aircraft carriers, cruisers,
destroyers, large amphibious ships, and large resupply ships);
 a larger proportion of smal er ships (such as frigates, corvettes, smal er
amphibious ships, smal er resupply ships, and perhaps smal er aircraft carriers);
and
 a new third tier of surface vessels about as large as corvettes or large patrol craft
that wil be either lightly manned, optional y manned, or unmanned, as wel as
large UUVs.

5 In December 2019, it was reported that the Office of Management and Budget (OMB) had directed the Navy to
include in its FY2021 budget submission a legislative proposal to formally change the definition of which ships count
toward the quoted size of the Navy (known as the number of battle force ships) to include not only manned ships, but
also large UVs that operate essentially as unmanned ships. (See Justin Katz, “ OMB: Pentagon Must Submit Proposal to
‘Redefine’ Battleforce Ships to Include Unmanned Vehicles,” Inside Defense, December 20, 2019; Joseph T revithick,
“White House Asks Navy T o Include New Unmanned Vessels In Its Ambitious 355 Ship Fleet Plan,” The Drive,
December 20, 2019; Paul McCleary, “Navy T o Slash 24 Ships in 2021 Plan, Bolster Unmanned Effort,” Breaking
Defense
, December 20, 2019, David B. Larter, “ Pentagon Proposes Big Cuts to US Navy Destroyer Construction,
Retiring 13 Cruisers,” Defense News, December 24, 2019.)
In January 2020, Admiral Michael Gilday, the Chief of Naval Operations, stated that the top-level expression of the
ship force-level goal resulting from the Navy’s next FSA would not include UVs. (See, for example, Sam LaGrone,
“CNO Gilday Calls for Budget Increase to Reach 355 Ship Fleet; New Battle Force Count Won’t Include Unmanned
Ships,” USNI News, January 14, 2020; Rich Abott, “CNO: Ship Count Will Not Include Unmanned; Bigger T opline
Needed For Fleet Goal,” Defense Daily, January 15, 2020; John M. Doyle, “CNO Wants Larger Slice of Defense
Budget to Modernize, Meet China T hreat,” Seapower, January 15, 2020; Rich Abott, “CNO: Ship Count Will Not
Include Unmanned; Bigger T opline Needed For Fleet Goal,” Defense Daily, January 15, 2020.)
In September 2020, then-Secretary of Defense Mark Esper signaled that the stated ship-force level goal will include
large UVs. (See, for example, Megan Eckstein, “ Esper: Unmanned Vessels Will Allow the Navy to Reach 355 -Ship
Fleet,” USNI News, September 18, 2020.)

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

Navy and DOD leaders believe that shifting to a more distributed fleet arc hitecture is
operationally necessary, to respond effectively to the improving maritime anti-
access/area-denial (A2/AD) capabilities of other countries, particularly China;6
technically feasible as a result of advances in technologies for UVs and for
networking widely distributed maritime forces that include significant numbers
of UVs; and
affordable—no more expensive, and possibly less expensive, than the current
fleet architecture for a given level of overal fleet capability, so as to fit within
expected future Navy budgets.
Regarding the first point above, shifting to a more distributed force architecture, Navy and
Marine Corps officials have indicated, wil support implementation of the Navy and Marine
Corps’ new overarching operational concept, cal ed Distributed Maritime Operations (DMO), and
a supporting Marine Corps operational concept cal ed Expeditionary Advanced Base Operations
(EABO).7 A key aim of DMO and EABO is to improve the ability of the Navy and Marine Corps
to counter China’s improving maritime military capabilities.
Some elements of the Navy’s new, more distributed fleet architecture are reflected in the Navy’s
FY2021 and FY2022 budget submissions, including the following:
 procurement of FFG-62-class frigates;8
 development of a smal er amphibious warship cal ed the Light Amphibious
Warship (LAW);9
 development of a smal er resupply ship cal ed the Next-Generation Medium
Logistics Ship;10

6 See, for example, David B. Larter, “With China Gunning for Aircraft Carriers, US Navy Says It Must Cha nge How It
Fights,” Defense News, December 6, 2019; Arthur H. Barber, “Redesign the Fleet,” U.S. Naval Institute Proceedings,
January 2019. Some observers have long urged the Navy to shift to a more distributed fleet architecture, on the grounds
that the Navy’s current architecture—which concentrates much of the fleet’s capability into a relatively limited number
of individually larger and more expensive surface ships—is increasingly vulnerable to attack by the improving A2/AD
capabilities (particularly ant i-ship missiles and their supporting detection and targeting systems) of potential
adversaries, particularly China. Shifting to a more distributed architecture, these observers have argued, would

complicate an adversary’s targeting challenge by presenting the adversary with a larger number of Navy units
to detect, identify, and track;

reduce the loss in aggregate Navy capability that would result from the destruction of an individual Navy
platform;

give U.S. leaders the option of deploying USVs and UUVs in wartime to sea locations that would be
tactically advantageous but too risky for manned ships; and

increase the modularity and reconfigurability of the fleet for adapting to changing mission needs.

Some Observations on the December 9, 2020, Document
Observations on the December 9, 2020, document include the following:
 The December 9, 2020, document is not the FY2021 30-year shipbuilding plan,
because the five-year and 30-year shipbuilding tables in the document begin with
FY2022, not FY2021 (as they would for an FY2021 30-year shipbuilding plan),
and because the data in the document’s five-year shipbuilding table includes
changes from the Navy’s FY2021 five-year (FY2021-FY2025) shipbuilding plan
for the years FY2022-FY2025. An FY2021 30-year shipbuilding plan would
have five-year and 30-year tables beginning with FY2021, and the details for the
period FY2022-FY2025 would match those of the Navy’s FY2021 five-year
(FY2021-FY2025) shipbuilding plan. The FY2021 30-year shipbuilding plan was
not submitted.
 The December 9, 2020, document is not a final version of the FY2022
shipbuilding plan. The final version of the FY2022 30-year shipbuilding plan is a
document that would be submitted in conjunction with DOD’s proposed FY2022
budget.
 The December 9, 2020, document can be viewed as the Trump Administration’s
own vision for future Navy force structure14 and/or a draft version of the FY2022
30-year Navy shipbuilding plan. It is not unprecedented for an Administration to
present, in its final weeks in office, a document presenting information on what it
says it would have submitted as its proposed DOD budget for the coming fiscal
year.15

December 9, 2020.

report to the President and Congress (a report which at the time was submitted by the Secretary of Defense each year)

 In developing a new force-level goal for the Navy and preparing the FY2022 30-
year shipbuilding plan that is to be submitted in conjunction with DOD’s
proposed FY2022 budget, the Biden Administration may choose to adopt, revise,
or set aside the December 9, 2020, document. The force-level goal and FY2022
30-year shipbuilding plan developed by the Biden Administration could differ
from those in the December 9, 2020, document.
 The December 9, 2020, document is available as a potential comparative
reference for assessing and discussing future Navy force-level goals, budgets,
and 30-year shipbuilding plans.16
 Although the Biden Administration’s force-level goal and FY2022 30-year
shipbuilding plan may differ from those shown in the December 9, 2020,
document, the general idea of shifting the Navy toward a more distributed force
architecture that includes a smal er proportion of larger ships, a larger proportion
of smal er ships, and a new third tier of large UVs may remain, because support
for this change has been developing within Navy planning for years as a
consequence of changes in technologies and the capabilities of potential
adversaries. As noted earlier, some elements of the more distributed architecture
are reflected in the Navy’s FY2021 and FY2022 budget submissions.
 The force-level goal presented in the December 9, 2020, document is not fully
described. As shown in Table 2, the numerical goals for every ship category
other than SSBNs are expressed as a ranges, and some of the ranges are relatively
wide. Fleets of markedly varying compositions could fit within the incompletely
described force-level goal in the December 9, 2020, document.
 The costs of achieving the December 9, 2020, document’s force-level goal would
be greater than the costs of achieving the 355-ship force-level goal. An April
2021 Congressional Budget Office (CBO) report on the cost to implement the
shipbuilding plan in the December 9, 2020, document states that, using Navy
estimates, average annual new-ship construction costs would be 28% higher
under the December 9, 2020, document than under the Navy’s FY2020 30-year-
shipbuilding plan.17 The April 2021 CBO report also states
The December 2020 plan would require average annual shipbuilding appropriations almost
50 percent larger than the average over the past five years. CBO estimates that total
shipbuilding costs, including costs for nuclear refueling and unmanned systems, would
average about $34 billion per year (in 2021 dollars), 10 percent more than the Navy

that presented details of what the George H.W. Bush Administration said it would have included in its proposed
FY1994 DOD budget, if that Administration had been reelected. See Department of Defense, Annual Report to the
President and Congress, Dick Cheney, Secretary of Defense
, January 1993, 181 pp., accessed December 23, 2020, at
https://history.defense.gov/Historical-Sources/Secretary-of-Defense-Annual-Reports/, a website that, as of December
23, 2020, presented the annual reports of the Secretary of Defense for the years 1969 through 2005 ( except for 1969-
1970 and 1972). T he report’s section on naval forces on pages 81 -85 includes, among other things, T able 14 on page
82, which projects the numbers and types of Navy ships out to the year FY1999 under the Administration’s vision.

estimates. Annual operation and support costs for the fleet would grow from $74 billion
today to $113 billion by 2051. The Navy’s total budget would increase from about $200
billion today to $279 billion (in 2021 dollars) by 2051.18
 Some observers have questioned the prospective affordability of the December 9,
2020, document’s force-level goal, particularly in a scenario where the overal
DOD budget in coming years does not grow in real (i.e., inflation-adjusted)
terms.19 If DOD’s total budget were not increased to accommodate the additional
costs of the document’s force-level goal, achieving the document’s force-level
goal would require reducing funding for other DOD priorities. Some observers
have speculated that funding the document’s force-level goal would involve
reducing funding for the Army, on the grounds that countering China’s military is
DOD’s stated top planning priority, and that the Western Pacific—the region at
the center of the evolving U.S.-China military balance—is, for the United States,
primarily a maritime and aerospace theater rather than a ground-forces-centric
theater.20
March 2021 Press Report About Potential Reduction in Aircraft Carrier Force
A March 10, 2021, press report stated
The Pentagon is again considering a reduction in aircraft carrier force structure as part of
the upcoming Fiscal Year 2022 budget submission to Congress, according to two sources
familiar with the discussions.
In order to meet a proposed $704 billion to $708 billion topline for the first Biden Defense
Department budget—the Trump administration’s FY 2022 budget proposed $722 billion—
the Office of the Secretary of Defense is weighing how it could build in savings by reducing
the carrier force, the two sources familiar with the ongoing internal discussion told USNI
News on Wednesday [March 10]….
The search for cost savings could include revisiting a 2019 Trump administration proposal
to take aircraft carrier USS Harry S. Truman (CVN-75) out of the inventory rather than
conduct a mid-life refit and refueling, a legislative source told USNI News.

page with the header “ At a Glance” that immediately follows the report’s cover.

Materialize, Experts Say,” Defense News, December 11, 2020.

10, 2020.
It might also be argued that while a shift in the U.S. role in the world to a more-restrained U.S. role—something that
some observers have advocated (and which other observers oppose) —might imply a reduction in overall U.S. defense
spending and the total required size and capabilities of the U.S. military, it might not necessarily imply a reduction in
the Navy’s budget and the required size and capabilities of the Navy, because the United States under a more -restrained
role might need to rely as much or more than it does now on its ability to use the world’s oceans as a buffer for
protection from potential security challenges that might arise in Eurasia.. For additional discussion, see page 8 of CRS

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

A separate source familiar with the carrier review said that, additionally, the entire scope
of the shipbuilding budget was under scrutiny.
The idea of retiring an active carrier has circulated on Capitol Hill to the point where House
Armed Services seapower and projection forces ranking member Rep. Rob Wittman (R-
Va.) asked a senior admiral on Wednesday if retiring an aircraft carrier ahead of the
overhaul was a good idea.
“In your best professional military judgment, do you believe—considering the current
stress on the aircraft carrier force—that taking out an aircraft carrier from service just
before its mid-life refueling would be a smart thing to do?” Wittman asked U.S. Indo-
Pacific Command commander Adm. Phil Davidson on Wednesday.
Davidson responded, “there is no capability that we have that can substitute for an aircraft
carrier in my view. You can see by the strain of the deployments over the course of the last
year that they are in high demand by all the combatant commanders, and sustaining that
capability going forward in my view is critically important. I’m in support of the law which
calls for the number of carriers in the United States.”
When asked about the exchange between Wittman and Davidson and if cutting carriers was
a consideration, Pentagon spokesman John Kirby told USNI News on Wednesday that DoD
would not comment on the budget ahead of its rollout.21
The future aircraft carrier force level has been a frequent matter of discussion over the years, and
(correctly or not) is often the starting point or the center of broader discussions over the future
size and composition of the Navy. Decisions on the future aircraft carrier force level could have
implications for required numbers of aircraft carrier air wings, surface combatants, and underway
replenishment ships (such as oilers) for resupplying aircraft carriers and surface combatants that
are operating at sea. A reduction in aircraft carrier force levels could, on the one hand, lead to a
reduction in the number of surface combatants required for operating with aircraft carriers as part
of carrier strike groups. It could also, however, lead to an increase in required numbers of surface
combatants if the missile-firing capacity of surface combatants is used to compensate for a
reduction in the fleet’s strike capability resulting from a reduction in the number of aircraft
carriers.
Factors involved in discussions about the future aircraft carrier force level include but are not
limited to
 the capabilities and costs (including procurement costs and life-cycle operation
and support [O&S] costs) of aircraft carriers and their embarked air wings, and
how those capabilities and costs compare to those of other U.S. military forces;
 the prospective survivability of aircraft carriers in conflicts against adversaries
(such as China) with highly capable anti-ship missiles;
 the numbers of carriers needed to support policymaker-desired levels of day-to-
day aircraft carrier forward presence in various regions around the world; and
 the utility of carriers for purposes other than high-end combat, including
deterrence of potential regional adversaries, reassurance of al ies and partners,
signaling U.S. commitment and resolve, and non-combat operations such as
humanitarian assistance/disaster response (HA/DR) operations.

Review,” USNI News, March 10 (updated March 11), 2021.

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

A reduction in the planned number of nuclear-powered aircraft carriers (CVNs) could lead to
Navy proposals for one or more of the following:
 accelerated retirements for one or more Nimitz-class CVNs that have already
received their mid-life nuclear refueling overhauls (which are cal ed Refueling
Complex Overhauls, or RCOHs);
 the cancel ation of one or more planned RCOHs for Nimitz-class CVNs that have
not yet received RCOHs, and the consequent early retirement of one or more of
these ships;
 a deferral or cancel ation of the procurement of the aircraft carrier CVN-82,
which under the Navy’s FY2020 30-year shipbuilding plan was scheduled for
FY2028; and/or
 the deferral or cancel ation of the construction of the aircraft carrier CVN-81,
which could require modifying the current two-ship construction contract for the
aircraft carriers CVN-80 and CVN-81.
April 2021 Comments from Chief of Naval Operations
An April 27, 2021, press report states:
Chief of Naval Operations Adm. Mike Gilday wants a bigger fleet, but his force level goal
falls well short of what some in the Defense Department are aiming for….
“Recently I was asked by a member of Congress what my North Star is with respect to
numbers right now,” Gilday said April 27 during a webinar hosted by the Center for
Strategic and Budgetary Assessments. “That's 355. I still think that's a really good
target.”…
… given the budget constraints that are expected in coming years, the Navy must grow the
fleet at an “affordable rate,” he said….
The military’s budget will be “lucky to actually keep pace with inflation,” Gilday said.
“What that will make most challenging, I think, is the fact that given the rise in personnel
costs, given the rise in operations and maintenance costs, which typically rise at a rate
higher than inflation, it will … potentially put a squeeze on the shipbuilding budget,” he
said.
Gilday said he’s taking a “realist approach” to the Navy’s investment strategy, and won’t
sacrifice readiness and capability in order to boost capacity.
“We need a fleet that's more ready and more capable and more lethal, more than we need
a bigger fleet that's less ready and less capable and less lethal,” he said.
Readiness is Gilday’s top priority. That includes investments in manpower and training.…
New capabilities that will require funding include hypersonic weapons, directed energy
systems and improved networking for joint all-domain command-and-control, he noted.
Gilday also wants to bring a large number of robotic platforms into the fleet in addition to
the 355-ship goal for manned vessels.
“It's an important part of the future,” Gilday said. “We can't afford to field the Navy like
we did in the previous century,” he added. Manned-unmanned teaming—which eventualy
will lead to a more autonomous fleet—is where the service is headed.

By the mid- to late-2030s, up to a third of the service’s surface and subsurface fleet could
be unmanned. Additionally, about 40 to 60 percent of future air wings could be
compromised of robotic aircraft, he projected.22

As shown in the table, the total of eight new ships requested for FY2022 is one more than the
total of seven new ships that were projected for FY2022 under the Navy’s FY2021 budget
submission, about two less than steady-state replacement rate for a 355-ship Navy (which is about
10 ships per year),23 and four less than the 12 new ships shown in the Trump Administration’s
December 9, 2020, shipbuilding document. (One of the 12 ships shown in the December 9, 2020,
document—the LHA amphibious assault ship—is a ship that, based on congressional action on
the Navy’s FY2020 and FY2021 budgets, is treated in CRS reports as a ship that was procured in
FY2021. Excluding this ship from those shown for FY2022 would reduce the total in the
December 9, 2020, document to 11 new ships.)24
As also shown in the table, the Navy’s proposed FY2022 budget requests $18.1 bil ion for
construction of new ships within its shipbuilding account (the Shipbuilding and Conversion,
Navy, or SCN, appropriation account), compared with $17.8 bil ion for construction of new ships
within the SCN account projected for FY2022 under the Navy’s FY2021 budget submission, and
$22.8 bil ion in FY2022 for construction of new ships within the SCN account in the December 9,
2020, document. The Navy’s proposed FY2022 request of $18.1 bil ion for construction of new
ships within the SCN account can also be compared to the FY2021 enacted total of $20.1 bil ion
for the construction of new ships within the SCN account.
FY2022 Five-Year (FY2022-FY2026) Shipbuilding Plan (Not Yet Submitted)
As shown in Table 4, the Navy has not yet submitted an FY2022 five-year (FY2022-FY2026)
shipbuilding plan.

23 T he steady-state replacement rate for a fleet of objects (i.e., ships, aircraft, vehicles) is the average annual rate of
procurement that, if maintained over the long run, would be sufficient to achieve and maintain the desired force level
over the long run. T he steady-state replacement rate is equal to the desired force level divided by average service life.
For the Navy, the steady-state replacement for the Navy’s 355-ship force-level goal is 355 ships divided by about 35
years, which is the approximate weighted average service life of a Navy ship. (T he weighted average service life is
calculated on the basis of various types and quantities of Navy ships within the 355 -ship plan and the expected service
lives for each ship type.) A figure of 355 divided by about 35 equates to a steady -state replacement rate of about 10
ships per year. T he steady-state replacement rate is an average annual figure—the actual rate can be either below or
above the steady-state rate in any given year. If the actual rate is below the steady -state replacement rate in one or more
years, then achieving and maintaining the desired force level would require the actual rate to be above the steady -state
replacement rate in one or more other years, so that the average rate achieved over the long run (in this case, over a
period of 35 years) equates to the steady-state replacement rate.

Although the executive branch is required by law to submit a 30-year shipbuilding plan each year
in conjunction with its annual budget submission, past Administrations have sometimes chosen to
not submit a 30-year shipbuilding plan during their first year in office, on the grounds that they
were spending that year reviewing and revising the previous Administration’s defense strategy,
plans, and programs, so as to create a basis for subsequently devising a 30-year shipbuilding plan.
In devising a 30-year shipbuilding plan to move the Navy toward its ship force-structure goal, key
assumptions and planning factors include but are not limited to ship construction times and
service lives, estimated ship procurement costs, projected shipbuilding funding levels, and
industrial-base considerations.

Issues for Congress
Key Questions
The issue for Congress is whether to approve, reject, or modify the Navy’s force-level goal, its
proposed FY2022 shipbuilding program, and its longer-term shipbuilding plans. Decisions that
Congress makes on this issue can substantial y affect Navy capabilities and funding requirements,
and the U.S. shipbuilding industrial base. Key questions for Congress include the following:
 Does the Biden Administration plan to present a new force-level goal to replace
the 355-ship goal, and if so, when?
 Does the Biden Administration plan to submit an FY2022 five-year (FY2022-
FY2026) shipbuilding plan and an FY2022 30-year (FY2022-FY2051)
shipbuilding plan, and if so, when?
 Is the Navy’s force-level goal (either the existing 355-ship goal or a possible
successor goal) appropriate for supporting U.S. national security strategy and
U.S. defense strategy?
 Is the more distributed fleet architecture envisioned by the Navy the most cost
effective fleet architecture for meeting future mission needs?
 Are the Navy’s proposed FY2022 shipbuilding program and (if submitted) its
FY2022 five-year and 30-year shipbuilding plans consistent with the Navy’s
force-level goal?
 Given finite defense resources and competing demands for defense funds, what is
the prospective affordability of the Navy’s shipbuilding plans?
 Does the U.S. shipbuilding industry, including both shipyards and supplier firms,
have adequate capacity for executing the Navy’s shipbuilding plans?
FY2022 Shipbuilding Funding Request Relative to Force-Level
Goal
One issue for Congress concerns the adequacy of the Navy’s FY2022 shipbuilding request
relative to Navy force-level goals. As noted earlier, the total of eight new ships requested for
FY2022 is one more than the total of seven new ships that were projected for FY2022 under the
Navy’s FY2021 budget submission, about two less than steady-state replacement rate for a 355-
ship Navy (which is about 10 ships per year),25 and four less than the 12 new ships shown in the

25 T he steady-state replacement rate for a fleet of objects (i.e., ships, aircraft, vehicles, etc.) is the average annual rate of
procurement that, if maintained over the long run, would be sufficient to achieve and maintain the desired force level
over the long run. T he steady-state replacement rate is equal to the desired force level divided by average service life.
For the Navy, the steady-state replacement for the Navy’s 355-ship force-level goal is 355 ships divided by about 35
years, which is the approximate weighted average service life of a Navy ship. (T he weighted average service life is
calculated on the basis of various types and quantities of Navy ships within the 355 -ship plan and the expected service
lives for each ship type.) A figure of 355 div ided by about 35 equates to a steady-state replacement rate of about 10
ships per year. T he steady-state replacement rate is an average annual figure—the actual rate can be either below or
above the steady-state rate in any given year. If the actual rate is below the steady-state replacement rate in one or more

Trump Administration’s December 9, 2020, shipbuilding document. (One of the 12 ships shown
in the December 9, 2020, document—the LHA amphibious assault ship—is a ship that, based on
congressional action on the Navy’s FY2020 and FY2021 budgets, is treated in CRS reports as a
ship that was procured in FY2021. Excluding this ship from those shown for FY2022 would
reduce the total in the December 9, 2020, document to 11 new ships.)26
As also noted earlier, the Navy’s proposed FY2022 budget requests $18.1 bil ion for construction
of new ships within its shipbuilding account (the Shipbuilding and Conversion, Navy, or SCN,
appropriation account), compared with $17.8 bil ion for construction of new ships within the
SCN account projected for FY2022 under the Navy’s FY2021 budget submission, $22.8 bil ion in
FY2022 for construction of new ships within the SCN account in the December 9, 2020,
document, and an enacted FY2021 total of $20.1 bil ion for the construction of new ships within
the SCN account.
Number of DDG-51s to Procure in FY2022
A related issue for Congress concerns the number of DDG-51 destroyers to procure in FY2022.
As shown in Table 3, the Navy’s proposed FY2022 budget requests the procurement of one
DDG-51 in FY2022, rather than the two DDG-51s that are cal ed for FY2022 under the FY2018-
FY2022 DDG-51 multiyear procurement (MYP) contract, and that were projected for FY2022
under the Navy’s FY2021 budget submission. The issue for Congress for FY2022 is whether to
fund the procurement of one DDG-51, two DDG-51s, or some other number of DDG-51s (such
as zero or three).
When procured at a rate of two per year, DDG-51s cost roughly $2.0 bil ion each. Due to the
reduced production economies of scale that would occur at a production rate of one ship per year,
the one DDG-51 requested for procurement in FY2022 has an estimated cost of $2,401.7 mil ion
(i.e., about $2.4 bil ion).
Procuring one DDG-51 rather than two DDG-51s in FY2022 would prevent the Navy from
fulfil ing its obligations in the final year of the FY2018-FY2022 DDG-51 MYP contract. Navy
officials state that as a result, the Navy would need to pay a $33 mil ion penalty to the DDG-51
shipbuilders (unless the Navy and the shipbuilders were to reach an agreement to amend the
terms of the MYP contract).
Navy officials have stated that requesting procurement of one DDG-51 rather than two DDG-51s
was an affordability measure—a means of helping the Navy remain within its budget topline
while meeting funding needs for other Navy programs. Procuring a second DDG-51 in FY2022 is
the number one item on the Navy’s FY2022 Unfunded Priorities List (UPL)—the service’s list of
programs it would prefer to be funded in FY2022, if additional funding were to become available.
The UPL states that procuring two DDG-51s rather than one DDG-51 in FY2022 would require
an additional $1,659.2 mil ion (i.e., about $1.7 bil ion) in shipbuilding funding. That figure is not
the cost of the second DDG-51—the second DDG-51’s procurement cost would be roughly $2.0
bil ion. Adding the second DDG-51, however, would reduce the estimated procurement cost of
the first DDG-51 due to the resulting increased production economies of scale. The figure of

years, then achieving and maintaining the desired force level would require the actual rate to be above the steady -state
replacement rate in one or more other years, so that the average rate achieved over the long run (in this case, over a
period of 35 years) equates to the steady-state replacement rate.

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

$1,659.2 mil ion is thus the net increase in shipbuilding funding that would be needed to procure
two DDG-51s rather than one DDG-51 in FY2022.
Supporters of procuring one DDG-51 might argue that in a situation of finite defense resources,
funding the procurement of two DDG-51s could require reducing funding for other Navy or DOD
programs by about $1.7 bil ion, which could reduce Navy or DOD capabilities in other ways; that
the Navy’s new fleet architecture may result in a reduction in the force-level goal for large
surface combatants; and that the DDG-51 industrial base (both shipyards and supplier firms) wil
be adequately supported by their existing backlog of DDG-51s and other Navy shipbuilding
work.
Supporters of procuring two DDG-51s might argue that it would help accelerate the introduction
of Flight III DDG-51s, with their new and more-capable SPY-6 radars, into the fleet; that it would
improve production economies of scale in the DDG-51 program; and that it would more strongly
support the DDG-51 industrial base. The second DDG-51’s position at the top of the Navy’s
FY2022 UPL, they might argue, shows that the second ship is a high-priority item for the Navy to
fund with offsetting reductions that Congress might be able to identify in reviewing and marking
up DOD’s proposed FY2022 budget.27
Proposed Ship Retirements
Another issue for Congress concerns the Navy’s proposals in its FY2022 budget submission for
retiring certain ships—particularly CG-47 class cruisers and Littoral Combat Ships (LCSs)—
years earlier than cal ed for under earlier Navy plans. The issue has become a matter of discussion
at hearings on the Navy’s proposed FY2022 budget.28
The Navy argues that modernization work on the cruisers that would be necessary for the ships to
remain in service is taking longer and costing more than estimated, that the LCSs that are
proposed for retirement (at only a fraction of their original y planned service lives) would require
expensive repairs and modifications to be able to be mission effective, and more general y that in
a situation of constrained funding, retiring these ships is a necessary step to retain sufficient
funding for other Navy needs, including programs to maintain and improve Navy readiness and to
develop new technologies that wil be needed to ensure the Navy’s combat effectiveness in
coming years.
Skeptics, while acknowledging the points made by the Navy, can argue that the proposed early
retirements would nevertheless reduce the total number of Navy ships at a time when the Navy is
trying to increase its fleet size, and that the solution to the Navy’s funding situation is to increase
the size of the defense budget and/or increase the Navy’s share of the defense budget.29

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

Affordability of the Shipbuilding Plan
Overview
The prospective affordability of the Navy’s force-level goal and associated 30-year shipbuilding
plan has been a matter of oversight focus for several years, and particularly since the enactment in
2011 of the Budget Control Act, or BCA (S. 365/P.L. 112-25 of August 2, 2011). Observers have
been especial y concerned about the prospective affordability of Navy shipbuilding plans during
the decade or so from the mid-2020s through the mid-2030s, when the Navy wants to procure
Columbia-class bal istic missile submarines as wel as replacements for large numbers of retiring
attack submarines, cruisers, and destroyers.30
Navy officials stated at hearings on the Navy’s FY2021 budget submission that achieving and
supporting a 355-ship fleet over the next 10 years would require increasing the Navy’s budget by
a cumulative total of $120 bil ion to $130 bil ion over the next ten years, or an average of $12
bil ion to $13 bil ion per year. This figure, Navy officials stated, included not only the cost of
procuring new ships, but costs associated with crewing, arming, operating, and maintaining a
355-ship fleet.31 Prior to that—in September and October 2019—Navy officials stated that if
Navy budgets in coming years remain at current levels in real (i.e., inflation-adjusted terms), the
Navy would not be able to properly maintain a fleet of more than 302 to 310 ships.32
Navy officials have made similar statements in their June 2021 testimony on the Navy’s proposed
FY2022 budget. A June 15, 2021, press report, for example, states:
The number of ships in the fleet, now at 296 ships, will decrease if the Navy continues to
have flat or declining budgets, the service’s top officer told Congress today.
Despite numerous evaluations showing the Navy needs more ships, Chief of Naval
Operations Adm. Mike Gilday told the House Armed Service Committee that without a
topline increase to the service’s budget, the fleet will only get smaller.
“As you all know, the results of analysis done over the past five years—whether inside the
Pentagon or outside—have been consistent and clear: America needs a larger, more capable
fleet,” Gilday said. “Our latest Future [Naval Force Structure] assessment provided the
headlights not only for the size of our future fleet, but importantly for the composition of
that fleet, the capabilities that it brings to the joint force. If the Navy’s [budget] top-line
remains flat or goes down further, the size of our fleet will definitely shrink.”…
Gilday told lawmakers that the service’s budget is trying to balance the need to pursue new
capabilities and technology with its readiness priorities. While the Navy has for years been

30 T he Navy’s 30-year plans in recent years have spotlighted for policymakers the substantial increase in Navy
shipbuilding funding that would be required to implement the 30-year plan during the decade or so from the mid-2020s
through the mid-2030s. As discussed in CRS testimony in 2011, a key function of the 30 -year shipbuilding plan is to
alert policymakers well ahead of time to periods of potentially higher funding requirements for Navy shipbuilding. (See
Statement of Ronald O’Rourke, Specialist in Naval Affairs, Congressional Research Service, before the House Armed
Services Committee, Subcommittee on Oversight and Investigations, hearing on the Departm ent of Defense’s 30-Year
Aviation and Shipbuilding Plans, June 1, 2011, 8 pp.)

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

building toward a goal of 355 ships, Gilday said the service only has enough money for
300 vessels with its current budget.33
In January 2020, Admiral Gilday stated that fully funding the Navy’s program goals, including
the attainment of a 355-ship fleet, would require al ocating a larger share of DOD’s budget to the
Navy.34
Potential Impact of Cost Growth
If one or more Navy ship designs turn out to be more expensive to build than the Navy estimates,
then the Navy’s shipbuilding plan as a whole would become more expensive to execute. As
detailed by CBO35 and GAO,36 lead ships in Navy shipbuilding programs in many cases have
turned out to be more expensive to build than the Navy had estimated. Ship designs that can be
viewed as posing a risk of being more expensive to build than the Navy estimates include but are
not necessarily limited to Columbia-class bal istic missile submarines and FFG-62 frigates, as
wel as other new classes of ships that the Navy wants to begin procuring years from now.
CBO Estimate Compared to Navy Estimate
The statute that requires the Navy to submit a 30-year shipbuilding plan each year (10 U.S.C.
231) also requires CBO to submit its own independent analysis of the potential cost of the 30-year
plan (10 U.S.C. 231[d]). CBO analyses of past Navy 30-year shipbuilding plans have general y
estimated the cost of implementing those plans to be higher than what the Navy estimated.
As mentioned earlier, an April 2021 Congressional Budget Office (CBO) report on the cost to
implement the shipbuilding plan in the December 9, 2020, shipbuilding document estimates that
the plan would require 10% more funding to implement than the Navy estimates.37 CBO
estimates that the cost of the first 10 years of the plan would be about 1% higher than the Navy
estimates, that the cost of the middle 10 years of the plan would be about 8% higher than the
Navy estimates, and that the cost of the final 10 years of the plan would be about 17% higher than
the Navy estimates.38
The growing divergence between CBO’s estimate and the Navy’s estimate as one moves from the
first 10 years of the 30-year plan to the final 10 years of the plan is due in part to a technical
difference between CBO and the Navy regarding the treatment of inflation. This difference
compounds over time, making it increasingly important as a factor in the difference between

CBO’s estimates and the Navy’s estimates the further one goes into the 30-year period. In other
words, other things held equal, this factor tends to push the CBO and Navy estimates further apart
as one proceeds from the earlier years of the plan to the later years of the plan.39
The growing divergence between CBO’s estimate and the Navy’s estimate as one moves from the
first 10 years of the 30-year plan to the final 10 years of the plan is also due to differences
between CBO and the Navy about the costs of certain ship classes, particularly classes that are
projected to be procured starting years from now. The designs of these future ship classes are not
yet determined, creating more potential for CBO and the Navy to come to differing conclusions
regarding their potential cost.
The ship class that is the largest contributor to the difference between CBO and Navy regarding
the cost of the shipbuilding plan in the December 9, 2020, document is the DDG(X) next-
generation destroyer, which the Navy wants to begin procuring years from now as the successor
to the DDG-51 destroyer design. The DDG(X), CBO says, accounts for 28% of the difference
between the CBO and Navy estimates. The second-largest source of difference by ship class is the
SSN(X) next-generation attack submarine, which the Navy wants to begin procuring years from
now as the successor to the Virginia-class SSN design. The SSN(X), CBO says, accounts for 20%
of the difference between the CBO and Navy estimates. Together, the DDG(X) and SSN(X)
account for 48%, or almost half, of the difference between the CBO and Navy estimates.
The third- and fourth-largest sources of difference by ship class are the Constellation (FFG-62)
class frigates that the Navy began procuring in FY2020 and a new class of large-payload
submarines that the Navy envisions procuring after procurement of Columbia-class SSBNs is
complete. CBO says that these two classes of ships each account for 12% of the difference
between the CBO and Navy estimates. Several other ship classes each account for between 1%
and 6% of the difference between the CBO and Navy estimates. The Columbia-class SSBN
accounts for 1% of the difference, and CBO estimates that DDG-51s wil cost 1% less than the
Navy estimates.40
Sustainment Cost
In addition to the issue of the cost to build new ships, the Navy in its FY2020 30-year
shipbuilding plan highlighted a concern over the potential costs to sustain a larger fleet. On this
issue, the FY2020 30-year shipbuilding plan stated in part
Coincident with the relatively new dynamic of purchasing more ships to grow the force
instead of simply replacing ships or shrinking the force, is the responsibility to “own” the
additional inventory when it arrives.
Consistent annual funding in the shipbuilding account is foundational for an efficient
industrial base in support of steady growth and long -term maintenance planning, but
equally important is the properly phased, additional funding needed for operations and
sustainment accounts as each new ship is delivered—the much larger fiscal burden over
the life of a ship and the essence of the challenge to remain balanced across the three
integral elements of readiness–capability–capacity. Because the Navy [until recently] has
been shrinking not growing, and because of the disconnected timespan from purchase to
delivery, often five years or more and often beyond the FYDP, there is risk of

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

underestimating the aggregate sustainment costs looming over the horizon that must now
be carefully considered in fiscal forecasting.
For a ship, the rough rule of thumb for cost is 30 percent for procurement and 70 percent
for operating and sustainment; for example, a ship that costs $1B to buy costs $3.3B to
own, amortized over its lifespan. Accordingly, multi-ship deliveries can add hundreds of
millions of dollars to a budget year, and then require the same funding per year thereafter,
compounded by additional deliveries in subsequent years and only offset by ship
retirements, which lag deliveries when growing the force. A similar dynamic occurs when
the life of a ship is extended. Sustainment resources programmed to shift from a retiring
ship to a new ship must now stay in place – for the duration of the extension. The burden
continues to grow until equilibrium is reached at the desired higher inventory, when
deliveries match retirements and all resourcing accounts reach steady-state at a higher,
enduring sustainment cost.
For perspective, the current budget, among the largest ever, supports a modern fleet of
approximately 300 ships, nearly 20 percent fewer than the goal of 355. The battle force
inventory… rises from 301 ships in FY2020 to [a projected figure of] 314 ships in FY2024,
and then 355 in FY2034. The programmed sustainment cost… is $24B [billion] in FY2020
and rises to $30B [billion in FY2024 in TY$ [then-year dollars]. When the battle force
inventory reaches 355 in FY2034, [the] estimated cost to sustain that fleet will approach
$40B (TY$), 32% higher than in FY2024. For now, included in this sustainment estimate
are only personnel, planned maintenance, and some operations; representing those costs
tied directly to owning and operating a ship, easily modeled today, and already line-item
accounted for in the budget. Equally important additional costs, but not yet included in the
future estimate, are those not easily associated with individual ships and require complex
modeling for long-term forecasting (beyond 3 to 5 years), such as the balance of the
operations accounts (market and schedule driven), modernization and ordnance (threat and
technology driven), infrastructure and training (services spread across many ships),
aviation detachments, networks and cyber support, plus others….
Less of a challenge when shrinking the force, the Navy is now working towards developing
the complex model needed to capture indirect costs for growing the force. Until then, macro
ratios are helpful in estimating rough orders of magnitude beyond the FYDP and for
identifying future areas of concern. Similar to procurement, estimates will be less precise
deeper into the plan. Recovering from the long-term investment imbalance has proven to
be costly, particularly in the readiness accounts. As readiness becomes more accurately
defined, the modeling will improve and so will the ability to mo re accurately forecast.
However, no matter the method, the anticipated cost of sustaining the proper mix of 355
ships is anticipated to be substantial, and reform efforts and balanced scalability will
continue to be the drivers going forward.41
As mentioned earlier, an April 2021 CBO report on the cost of the shipbuilding plan in the
December 9, 2020, shipbuilding document estimates that if the plan were implemented, the fleet’s
annual operation and support (O&S) costs in constant 2021 dollars would grow from $74 bil ion
today to $113 bil ion by 2051, and that the Navy’s total budget would increase in constant 2021
dollars from about $200 bil ion today to $279 bil ion by 2051.42

Capacity of Shipbuilding Industry
Areas of particular focus in recent years regarding the capacity of the U.S. shipbuilding industry
to execute the Navy’s shipbuilding plans include shipyard capacity for building submarines at
desired rates, and the capacity of supplier firms to support increased rates of production for both
submarines and surface ships. Shipyard capacity for conducting maintenance and overhaul work
on an expanded fleet is another concern, particularly given the delays and other difficulties the
Navy has experienced in recent years in executing overhaul and repair work on today’s fleet.43

• Telework across the Defense Industrial Base
• Closures due to travel restrictions
• Logistic implications caused by travel restrictions requiring commercial freight
• Availability of parts and supplies
• High absentee rates
• Local and state lockdowns
• Foreign Government Lockdowns
• Company/Supplier shutdowns
• Financial distress
• Social distancing across the industrial base (production line implications)

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

• Added costs for cleaning/Disinfecting and temperature sensors
• Added costs for PPE
• CARES Act Section 3610 costs to pay for contractor/subcontractor employees unable to
work due to COVID-19 impacts
The Department closely monitors and tracks approximately 22,000 critical contractors who
are most important to modernization and readiness. As of July 8, 2020, 977 of DoD’s
suppliers have closed since March 15, 2020. The average closure is over two weeks. 943
have reopened with 34 still closed. The biggest sectors affected have been Aviation, Space,
Combat Vehicles, Clothing and Textiles and Missiles. Some sectors like Aviation also have
significant impacts related to commercial aviation challenges.
The estimate currently does not include potential overhead rate increases due to layoffs,
especially if the contractor performs both government and commercial work. The
Department is also concerned with a potential loss of critical labor skills (e.g. welders) and
continue to work these issues by contract and location as we analyze the impact across the
Defense Industrial Base (DIB).
DoD’s Requirements
The Department currently estimates a potential cost to complete (or Request for Equitable
Adjustments) totaling about $10.8 billion and touching more than 106,000 jobs. This
estimate is calculated by considering the projected spend over this period for the portfolio,
assessment of the percentage of that spend attributed to direct labor, and application of
reported inefficiencies in that sector. The data from industry is showing approximately a
30-40% inefficiency across the DIB but in certain sectors like shipbuilding we are seeing
about a 50-60% inefficiency.
Projected cost overrun/inefficiency risk examples are as follows….

Navy [impact:] $4,664.0M (43,214 Jobs)
− Shipbuilding: Significant touch labor; greater facility impact from social distancing; and
strong union representation at some yards pushing for paid leave with facility shutdown.
Worker attendance rates range from 50% to 70% for blue collar workforce, and much of
the white collar workforce is teleworking. At least one of the big seven private shipyards
may shutdown. Recovery from a full shutdown would extend inefficiencies well into next
year after restart.
− Aircraft Procurement: Moderate touch labor but tends to enable better distancing. No
prime production impacts yet, but there are some sub-tier Component impacts. A couple
of short term plant shutdowns occurred in early April with possibly more in the near future.
− Other Procurement: Moderate touch labor; greater facility impacts from social
distancing, subtiers reporting issues (e.g. BAE York shut down for two days; returned with
50% workforce). Weapons manufacturer’s not seeing significant impacts yet as many not
located in high COVID impact areas.
− Fragility concerns: The DoN shares the Army’s long term fragility concern regarding
FLIR , combat vehicle transmissions, and aircraft engines (GE specifically). The DoN also
shares Army concerns about short term risk to textile manufacturers; body armor suppliers,
and small business electronics suppliers who feed guidance systems (PGK, GMLRS,
Excalibur) and wiring harnesses (vehicles, aircraft).

Missile Defense Agency [impact:] $593.5M (3,956 Jobs)

Congressional Research Service

25

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

− Aegis Program delays: SM-3 Block IIA production deliveries; Aegis Ashore Poland
construction (further delays); and Aegis Testing delays for Flight Test Missile (FTM)-44
(Aegis), FTM-31, and FTM-33.44
The Navy later clarified that the statement in the above passage that “[a]t least one of the big
seven private shipyards may shutdown” refers to the possibility of a shipyard closing temporarily
due to COVID-19, rather than to the possibility of a shipyard closing permanently.45
March 2021 Press Reports
A March 15, 2021, press report states
A year into the pandemic, a Defense News review tried to measure its toll on the defense
industry. The full scope of damage is complex and still coming into focus, but a broad
outline is becoming clear. Among the findings:
 Early in the pandemic, Pentagon leaders worried about the health of the industrial base
and program timelines. However, the largest firms have rebounded, and the biggest
projects are mostly on track. In the past year, at least half of the Pentagon’s major
defense acquisition programs experienced some kind of delay as a result of COVID-
19. Programs were able to recover, often in a matter of months following nearly $5
billion in federal aid and efforts to push money more quickly to suppliers. Pentagon
leaders have not listed all of the specific programs which have faced delays.
 Smaller companies—already imperiled before the pandemic—are still struggling, with
as many as 1 in 7 believing they will never return to pre-pandemic levels.
 Industry invested roughly $10 billion to reconfigure production lines and build
infrastructure for remote working, costs that if not addressed by Congress could
become amortized over time and potentially lead to overall per unit price increases.
 Finally, quantifying the human toll on the workforce is nearly impossible. The
Pentagon has not tracked deaths in the defense industry, and only two companies
Defense News contacted acknowledged employee deaths from the pandemic.46
A March 31, 2021, press report states
Absenteeism rates at public and private shipyards skyrocketed. Supply chains slowed. Top
officials and executives worried the pandemic would result in significant new delays for
already troubled Navy shipbuilding and maintenance programs….
But as the one-year anniversary of pandemic-related shutdowns passes, outside analysts,
the ranking Republican on the House shipbuilding subcommittee and the Navy itself say
the service successfully managed the crisis.47

Past Examples of Assistance to Shipyards and Supplier Firms
Potential options for Congress for providing assistance to shipyards and supplier firms whose
operations are impacted by the COVID-19 pandemic could take various forms. Some past
instances of assistance relating to shipbuilding include the following:
 Following Hurricane Katrina in August 2005, Congress provided $1.7 bil ion in
real ocated emergency supplemental appropriations to pay estimated higher
shipbuilding costs for 11 Navy ships under construction at the Ingal s shipyard in
Pascagoula, MS, and the Avondale shipyard upriver from New Orleans, LA.48
 The American Recovery and Reinvestment Act (ARRA) of 2009 (H.R. 1/P.L.
111-5 of February 17, 2009), which was enacted in response to the 2008-2009
recession, appropriated $100 mil ion for the Maritime Administration (MARAD)
to be used for making supplemental grants to smal shipyards as authorized under
Section 3508 of the Duncan Hunter National Defense Authorization Act for
Fiscal Year 2009 (S. 3001/P.L. 110-417 of October 14, 2008) or 46 U.S.C.
54101.49
 Following Hurricane Michael in October 2018, the Department of Homeland
Security (DHS), of which the Coast Guard is a part, announced on October 11,
2019, that DHS had granted extraordinary contractual relief to Eastern
Shipbuilding Group (ESG) of Panama City, FL, the builder of the first of the
Coast Guard’s new Offshore Patrol Cutters (OPCs), under P.L. 85-804 as
amended (50 U.S.C. 1431-1435). P.L. 85-804, original y enacted in 1958,
authorizes certain federal agencies to provide certain types of extraordinary relief
to contractors who are encountering difficulties in the performance of federal
contracts or subcontracts relating to national defense.50 ESG reportedly submitted

48 See CRS Report RS22239, Emergency Supplemental Appropriations for Hurricane Katrina Relief, by Keith Bea,
August 22, 2006, p. 6. T he report states
Citing the need for “special oversight” of these shipbuilding funds dedicated to cover property
damage, cleanup, idle payroll, and business disruption (that may also be covered by shipbuilders’
insurance), the appropriators added report language requiring that the Navy or Army, as applicable,
submit a report to the Appropriations Committees “certifying” that the costs were related to the
hurricanes and would not be paid for by FEMA or the shipbuilders’ insurers.

SSGNs, and the retirement of two other Trident SSBNs. Congress, in marking up this request, supported a
plan to convert al four available SSBNs into SSGNs.
e. With congressional approval, the goal has been temporarily be reduced to 10 carriers for the period
between the retirement of the carrier Enterprise (CVN-65) in December 2012 and entry into service of the
carrier Gerald R. Ford (CVN-78), currently scheduled for September 2015.
f.
For a time, the Navy characterized the goal as 11 carriers in the nearer term, and eventual y 12 carriers.
g. The 94-ship goal was announced by the Navy in an April 2011 report to Congress on naval force structure
and missile defense.
h. The Navy acknowledged that meeting a requirement for being able to lift the assault echelons of 2.0 Marine
Expeditionary Brigades (MEBs) would require a minimum of 33 amphibious ships rather than the 31 ships
shown in the February 2006 plan. For further discussion, see CRS Report RL34476, Navy LPD-17 Amphibious
Ship Procurement: Background, Issues, and Options for Congress
, by Ronald O'Rourke.
i.
Today’s Maritime Prepositioning Force (MPF) ships are intended primarily to support Marine Corps
operations ashore, rather than Navy combat operations, and thus are not counted as Navy battle force
ships. The planned MPF (Future) ships, however, would have contributed to Navy combat capabilities (for
example, by supporting Navy aircraft operations). For this reason, the ships in the planned MPF(F) squadron
were counted by the Navy as battle force ships. The planned MPF(F) squadron was subsequently
restructured into a different set of initiatives for enhancing the existing MPF squadrons; the Navy no longer
plans to acquire an MPF(F) squadron.
j.
The Navy no longer plans to acquire an MPF(F) squadron. The Navy, however, has procured or plans to
procure some of the ships that were previously planned for the squadron—specifical y, TAKE-1 class cargo
ships, and Mobile Landing Platform (MLP)/Afloat Forward Staging Base (AFSB) ships. These ships are
included in the total shown for “Other” ships. AFSBs are now cal ed Expeditionary Sea Base ships (ESBs).
k. The figure of 26 dedicated mine warfare ships included 10 ships maintained in a reduced mobilization status
cal ed Mobilization Category B. Ships in this status are not readily deployable and thus do not count as
battle force ships. The 375-ship proposal thus implied transferring these 10 ships to a higher readiness
status.
l.
Totals shown include 5 ships transferred from the Army to the Navy and operated by the Navy primarily
for the performance of Army missions.
m. This category includes, among other things, command ships and support ships.
n. The increase in this category from 17 ships under the February 2006 313-ship goal to 24 ships under the
apparent 328-ship goal included the addition of one TAGOS ocean surveil ance ship and the transfer into
this category of six ships—three modified TAKE-1 class cargo ships, and three Mobile Landing Platform
(MLP) ships—that were previously intended for the planned (but now canceled) MPF(F) squadron.

Appendix B. Comparing Past Ship Force Levels to
Current or Potential Future Levels
In assessing the appropriateness of the current or potential future number of ships in the Navy,
observers sometimes compare that number to historical figures for total Navy fleet size. Historical
figures for total fleet size, however, can be a problematic yardstick for assessing the
appropriateness of the current or potential future number of ships in the Navy, particularly if the
historical figures are more than a few years old, because
 the missions to be performed by the Navy, the mix of ships that make up the
Navy, and the technologies that are available to Navy ships for performing
missions al change over time; and
 the number of ships in the fleet in an earlier year might itself have been
inappropriate (i.e., not enough or more than enough) for meeting the Navy’s
mission requirements in that year.
Regarding the first bullet point above, the Navy, for example, reached a late-Cold War peak of
568 battle force ships at the end of FY1987,53 and as of April 22, 2021, included a total of 296
battle force ships. The FY1987 fleet, however, was intended to meet a set of mission requirements
that focused on countering Soviet naval forces at sea during a potential multitheater NATO-
Warsaw Pact conflict, while the April 2021 fleet is intended to meet a considerably different set of
mission requirements centered on countering China’s improving naval capabilities. In addition,
the Navy of FY1987 differed substantial y from the April 2021 fleet in areas such as profusion of
precision-guided air-delivered weapons, numbers of Tomahawk-capable ships, and the
sophistication of C4ISR systems and networking capabilities.54
In coming years, Navy missions may shift again, and the capabilities of Navy ships wil likely
have changed further by that time due to developments such as more comprehensive
implementation of networking technology, increased use of ship-based unmanned vehicles, and
the potential fielding of new types of weapons such as lasers or electromagnetic rail guns.
The 568-ship fleet of FY1987 may or may not have been capable of performing its stated
missions; the 296-ship fleet of April 2021 may or may not be capable of performing its stated
missions; and a fleet years from now with a certain number of ships may or may not be capable of
performing its stated missions. Given changes over time in mission requirements, ship mixes, and
technologies, however, these three issues are to a substantial degree independent of one another.
For similar reasons, trends over time in the total number of ships in the Navy are not necessarily a
reliable indicator of the direction of change in the fleet’s ability to perform its stated missions. An
increasing number of ships in the fleet might not necessarily mean that the fleet’s ability to

53 Some publications have stated that the Navy reached a peak of 594 ships at the end of FY1987. T his figure, however,
is the total number of active ships in the fleet, which is not the same as the total number of battle force ships. T he battle
force ships figure is the number used in government discussions of the size of the Navy. In recent years, the total
number of active ships has been larger than the total number of battle force ships. For example, the Naval History and
Heritage Command (formerly the Naval Historical Center) states that as of November 16, 2001, the Navy included a
total of 337 active ships, while the Navy states that as of November 19 , 2001, the Navy included a total of 317 battle
force ships. Comparing the total number of active ships in one year to the total number of battle force ships in another
year is thus an apples-to-oranges comparison that in this case overstates the decline since FY1987 in the number of
ships in the Navy. As a general rule to avoid potential statistical distortions, comparisons of the number of ships in the
Navy over time should use, whenever possible, a single counting method.
54 C4ISR stands for command and control, communications, computers, intelligence, surveillance, and reconnaissance.

perform its stated missions is increasing, because the fleet’s mission requirements might be
increasing more rapidly than ship numbers and average ship capability. Similarly, a decreasing
number of ships in the fleet might not necessarily mean that the fleet’s ability to perform stated
missions is decreasing, because the fleet’s mission requirements might be declining more rapidly
than numbers of ships, or because average ship capability and the percentage of time that ships
are in deployed locations might be increasing quickly enough to more than offset reductions in
total ship numbers.
Regarding the second of the two bullet points above, it can be noted that comparisons of the size
of the fleet today with the size of the fleet in earlier years rarely appear to consider whether the
fleet was appropriately sized in those earlier years (and therefore potential y suitable as a
yardstick of comparison), even though it is quite possible that the fleet in those earlier years
might not have been appropriately sized, and even though there might have been differences of
opinion among observers at that time regarding that question. Just as it might not be prudent for
observers years from now to tacitly assume that the 296-ship Navy of September 2020 was
appropriately sized for meeting the mission requirements of 2020, even though there were
differences of opinion among observers on that question, simply because a figure of 296 ships
appears in the historical records for 2020, so, too, might it not be prudent for observers today to
tacitly assume that the number of ships of the Navy in an earlier year was appropriate for meeting
the Navy’s mission requirements that year, even though there might have been differences of
opinion among observers at that time regarding that question, simply because the size of the Navy
in that year appears in a table like Table G-1.
Previous Navy force structure plans, such as those shown in Table A-1, might provide some
insight into the potential adequacy of a proposed new force-structure plan, but changes over time
in mission requirements, technologies available to ships for performing missions, and other force-
planning factors, as wel as the possibility that earlier force-structure plans might not have been
appropriate for meeting the mission demands of their times, suggest that some caution should be
applied in using past force structure plans for this purpose, particularly if those past force
structure plans are more than a few years old. The Reagan-era goal for a 600-ship Navy, for
example, was designed for a Cold War set of missions focusing on countering Soviet naval forces
at sea, which is not an appropriate basis for planning the Navy today, and there was considerable
debate during those years as to the appropriateness of the 600-ship goal.55

55 Navy force structure plans that predate those shown in Table A-1 include the Reagan-era 600-ship goal of the 1980s,
the Base Force fleet of more than 400 ships planned during the final two years of the George H. W. Bush
Administration, the 346-ship fleet from the Clinton Administration’s 1993 Bottom -Up Review (or BUR, sometimes
also called Base Force II), and the 310-ship fleet of the Clinton Administration’s 1997 QDR. T he table below

Appendix C. Industrial Base and Employment
Aspects of Additional Shipbuilding Work
This appendix presents background information on the ability of the industrial base to take on the
additional shipbuilding work associated with achieving and maintaining the Navy’s 355-ship
force-level goal and on the employment impact of additional shipbuilding work.
Industrial Base Ability
The U.S. shipbuilding industrial base has some unused capacity to take on increased Navy
shipbuilding work, particularly for certain kinds of surface ships, and its capacity could be
increased further over time to support higher Navy shipbuilding rates. Navy shipbuilding rates
could not be increased steeply across the board overnight—time (and investment) would be
needed to hire and train additional workers and increase production facilities at shipyards and
supplier firms, particularly for supporting higher rates of submarine production. Depending on
their specialties, newly hired workers could be initial y less productive per unit of time worked
than more experienced workers.
Some parts of the shipbuilding industrial base, such as the submarine construction industrial base,
could face more chal enges than others in ramping up to the higher production rates required to
build the various parts of the 355-ship fleet. Over a period of a few to several years, with
investment and management attention, Navy shipbuilding could ramp up to higher rates for
achieving a 355-ship fleet over a period of 20-30 years.
An April 2017 CBO report stated that
all seven shipyards [currently involved in building the Navy’s major ships] would need to
increase their workforces and several would need to make improvements to their
infrastructure in order to build ships at a faster rate. However, certain sectors face greater
obstacles in constructing ships at faster rates than others: Building more submarines to
meet the goals of the 2016 force structure assessment would pose the greatest challenge to
the shipbuilding industry. Increasing the number of aircraft carriers and surface combatants
would pose a small to moderate challenge to builders of those vessels. Finally, building
more amphibious ships and combat logistics and support ships would be the least
problematic for the shipyards. The workforces across those yards would need to increase
by about 40 percent over the next 5 to 10 years. Managing the growth and training of those
new workforces while maintaining the current standard of quality and efficiency would
represent the most significant industrywide challenge. In addition, industry and Navy
sources indicate that as much as $4 billion would need to be invested in the physical
infrastructure of the shipyards to achieve the higher production rates required under the
[notional] 15-year and 20-year [buildup scenarios examined by CBO]. Less investment
would be needed for the [notional] 25-year or 30-year [buildup scenarios examined by
CBO].56
A January 13, 2017, press report states the following:
The Navy’s production lines are hot and the work to prepare them for the possibility of
building out a much larger fleet would be manageable, the service’s head of acquisition
said Thursday.
From a logistics perspective, building the fleet from its current 274 ships to 355, as
recommended in the Navy’s newest force structure assessment in December, would be

straightforward, Assistant Secretary of the Navy for Research, Development and
Acquisition Sean Stackley told reporters at the Surface Navy Association’s annual
symposium.
“By virtue of maintaining these hot production lines, frankly, over the last eight years, our
facilities are in pretty good shape,” Stackley said. “In fact, if you talked to industry, they
would say we’re underutilizing the facilities that we have.”
The areas where the Navy would likely have to adjust “tooling” to answer demand for a
larger fleet would likely be in Virginia-class attack submarines and large surface
combatants, the DDG-51 guided missile destroyers —two ship classes likely to surge if the
Navy gets funding to build to 355 ships, he said.
“Industry’s going to have to go out and procure special tooling associated with going from
current production rates to a higher rate, but I would say that’s easily done,” he said.
Another key, Stackley said, is maintaining skilled workers —both the builders in the yards
and the critical supply-chain vendors who provide major equipment needed for ship
construction. And, he suggested, it would help to avoid budget cuts and other events that
would force workforce layoffs.
“We’re already prepared to ramp up,” he said. “In certain cases, that means not laying off
the skilled workforce we want to retain.”57
A January 17, 2017, press report states the following:
Building stable designs with active production lines is central to the Navy’s plan to grow
to 355 ships. “if you look at the 355-ship number, and you study the ship classes (desired),
the big surge is in attack submarines and large surface combatants, which today are DDG-
51 (destroyers),” the Assistant Secretary of the Navy, Sean Stackley, told reporters at last
week’s Surface Navy Association conference. Those programs have proven themselves
reliable performers both at sea and in the shipyards.
From today’s fleet of 274 ships, “we’re on an irreversible path to 308 by 2021. Those ships
are already in construction,” said Stackley. “To go from there to 355, virtually all those
ships are currently in production, with some exceptions: Ohio Replacement, (we) just got
done the Milestone B there (to move from R&D into detailed design); and then upgrades
to existing platforms. So we have hot production lines that will take us to that 355-ship
Navy.”58
A January 24, 2017, press report states the following:
Navy officials say a recently determined plan to increase its fleet size by adding more new
submarines, carriers and destroyers is “executable” and that early conceptual work toward
this end is already underway....
Although various benchmarks will need to be reached in order for this new plan to come
to fruition, such as Congressional budget allocations, Navy officials do tell Scout Warrior
that the service is already working—at least in concept—on plans to vastly enlarge the
fleet. Findings from this study are expected to inform an upcoming 2018 Navy
Shipbuilding Plan, service officials said.59

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

Brian Cuccias, president of Ingalls Shipbuilding [a shipyard owned by Huntington Ingals
Industries (HII) that builds Navy destroyers and amphibious ships as well as Coast Guard
cutters], said Ingalls, which is currently building 10 ships for four Navy and Coast Guard
programs at its 800-acre facility in Pascagoula, Miss., could build more because it is using
only 70 to 75 percent of its capacity.60
A March 2017 press report states the following:
As the Navy calls for a larger fleet, shipbuilders are looking toward new contracts and
ramping up their yards to full capacity....
The Navy is confident that U.S. shipbuilders will be able to meet an increased demand,
said Ray Mabus, then-secretary of the Navy, during a speech at the Surface Navy
Association’s annual conference in Arlington, Virginia.
They have the capacity to “get there because of the ships we are building today,” Mabus
said. “I don’t think we could have seven years ago.”
Shipbuilders around the United States have “hot” production lines and are manufacturing
vessels on multi-year or block buy contracts, he added. The yards have made investments
in infrastructure and in the training of their workers.
“We now have the basis ... [to] get to that much larger fleet,” he said....
Shipbuilders have said they are prepared for more work.
At Ingalls Shipbuilding—a subsidiary of Huntington Ingalls Industries—10 ships are under
construction at its Pascagoula, Mississippi, yard, but it is under capacity, said Brian
Cuccias, the company’s president.
The shipbuilder is currently constructing five guided -missile destroyers, the latest San
Antonio-class amphibious transport dock ship, and two national security cutters for the
Coast Guard.
“Ingalls is a very successful production line right now, but it has the ability to actualy
produce a lot more in the future,” he said during a briefing with reporters in January.
The company’s facility is currently operating at 75 percent capacity, he noted....
Austal USA—the builder of the Independence-variant of the littoral combat ship and the
expeditionary fast transport vessel—is also ready to increase its capacity should the Navy
require it, said Craig Perciavalle, the company’s president.
The latest discussions are “certainly something that a shipbuilder wants to hear,” he said.
“We do have the capability of increasing throughput if the need and demand were to arise,
and then we also have the ability with the present workforce and facility to meet a different
mix that could arise as well.”
Austal could build fewer expeditionary fast transport vessels and more littoral combat
ships, or vice versa, he added.
“The key thing for us is to keep the manufacturing lines hot and really leverage the
momentum that we’ve gained on both of the programs,” he said.
The company—which has a 164-acre yard in Mobile, Alabama—is focused on the
extension of the LCS and expeditionary fast transport ship program, but Perciavalle noted
that it could look into manufacturing other types of vessels.

“We do have excess capacity to even build smaller vessels … if that opportunity were to
arise and we’re pursuing that,” he said.
Bryan Clark, a naval analyst at the Center for Strategic and Budgetary Assessments, a
Washington, D.C.-based think tank, said shipbuilders are on average running between 70
and 80 percent capacity. While they may be ready to meet an increased demand for ships,
it would take time to ramp up their workforces.
However, the bigger challenge is the supplier industrial base, he said.
“Shipyards may be able to build ships but the supplier base that builds the pumps … and
the radars and the radios and all those other things, they don’t necessarily have that ability
to ramp up,” he said. “You would need to put some money into building up their capacity.”
That has to happen now, he added.
Rear Adm. William Gallinis, program manager for program executive office ships, said
what the Navy must be “mindful of is probably our vendor base that support the shipyards.”
Smaller companies that supply power electronics and switchboards could be challenged,
he said.
“Do we need to re-sequence some of the funding to provide some of the facility
improvements for some of the vendors that may be challenged? My sense is that the
industrial base will size to the demand signal. We just need to be mindful of how we
transition to that increased demand signal,” he said.
The acquisition workforce may also see an increased amount of stress, Gallinis noted. “It
takes a fair amount of experience and training to get a good contracting officer to the point
to be [able to] manage contracts or procure contracts.”
“But I don’t see anything that is insurmountable,” he added.61
At a May 24, 2017, hearing before the Seapower subcommittee of the Senate Armed Services
Committee on the industrial-base aspects of the Navy’s 355-ship goal, John P. Casey, executive
vice president–marine systems, General Dynamics Corporation (one of the country’s two
principal builders of Navy ships) stated the following:
It is our belief that the Nation’s shipbuilding industrial base can scale-up hot production
lines for existing ships and mobilize additional resources to accomplish the significant
challenge of achieving the 355-ship Navy as quickly as possible....
Supporting a plan to achieve a 355-ship Navy will be the most challenging for the nuclear
submarine enterprise. Much of the shipyard and industrial base capacity was eliminated
following the steep drop-off in submarine production that occurred with the cancellation
of the Seawolf Program in 1992. The entire submarine industrial base at all levels of the
supply chain will likely need to recapitalize some portion of its facilities, workforce, and
supply chain just to support the current plan to build the Columbia Class SSBN program,
while concurrently building Virginia Class SSNs. Additional SSN procurement wil
require industry to expand its plans and associated investment beyond the level today....
Shipyard labor resources include the skilled trades needed to fabricate, build and outfit
major modules, perform assembly, test and launch of submarines, and associated support
organizations that include planning, material procurement, inspection, quality assurance,
and ship certification. Since there is no commercial equivalency for Naval nuclear
submarine shipbuilding, these trade resources cannot be easily acquired in large numbers
from other industries. Rather, these shipyard resources must be acquired and developed
over time to ensure the unique knowledge and know-how associated with nuclear

61 Yasmin T adjdeh, “Navy Shipbuilders Prepared for Proposed Fleet Buildup,” National Defense, March 2017.
Congressional Research Service

39

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

submarine shipbuilding is passed on to the next generation of shipbuilders. The
mechanisms of knowledge transfer require sufficient lead time to create the proficient,
skilled craftsmen in each key trade including welding, electrical, machining, shipfitting,
pipe welding, painting, and carpentry, which are among the largest trades that would need
to grow to support increased demand. These trades will need to be hired in the numbers
required to support the increased workload. Both shipyards have scalable processes in place
to acquire, train, and develop the skilled workforce they need to build nuclear ships. These
processes and associated training facilities need to be expanded to support the increased
demand. As with the shipyards, the same limiting factors associated with facilities,
workforce, and supply chain also limit the submarine unique first tier suppliers and sub-
tiers in the industrial base for which there is no commercial equivalency....
The supply base is the third resource that will need to be expanded to meet the increased
demand over the next 20 years. During the OHIO, 688 and SEAWOLF construction
programs, there were over 17,000 suppliers supporting submarine construction programs.
That resource base was “rationalized” during submarine low rate production over the last
20 years. The current submarine industrial base reflects about 5,000 suppliers, of which
about 3,000 are currently active (i.e., orders placed within the last 5 years), 80% of which
are single or sole source (based on $). It will take roughly 20 years to build the 12 Columbia
Class submarines that starts construction in FY21. The shipyards are expanding strategic
sourcing of appropriate non-core products (e.g., decks, tanks, etc.) in order to focus on core
work at each shipyard facility (e.g., module outfitting and assembly). Strategic sourcing
will move demand into the supply base where capacity may exist or where it can be
developed more easily. This approach could offer the poten tial for cost savings by
competition or shifting work to lower cost work centers throughout the country. Each
shipyard has a process to assess their current supply base capacity and capability and to
determine where it would be most advantageous to perform work in the supply base....
Achieving the increased rate of production and reducing the cost of submarines will require
the Shipbuilders to rely on the supply base for more non-core products such as structural
fabrication, sheet metal, machining, electrical, and standard parts. The supply base must be
made ready to execute work with submarine-specific requirements at a rate and volume
that they are not currently prepared to perform. Preparing the supply base to execute
increased demand requires early non-recurring funding to support cross-program
construction readiness and EOQ funding to procure material in a manner that does not hold
up existing ship construction schedules should problems arise in supplier qualification
programs. This requires longer lead times (estimates of three years to create a new
qualified, critical supplier) than the current funding profile supports....
We need to rely on market principles to allow suppliers, the shipyards and GFE material
providers to sort through the complicated demand equation across the multiple ship
programs. Supplier development funding previously mentioned would support non-
recurring efforts which are needed to place increased orders for material in multiple market
spaces. Examples would include valves, build-to-print fabrication work, commodities,
specialty material, engineering components, etc. We are engaging our marine industry
associations to help foster innovative approaches that could reduce costs and gain
efficiency for this increased volume....
Supporting the 355-ship Navy will require Industry to add capability and capacity across
the entire Navy Shipbuilding value chain. Industry will need to make investment decisions
for additional capital spend starting now in order to meet a step change in d emand that
would begin in FY19 or FY20. For the submarine enterprise, the step change was already
envisioned and investment plans that embraced a growth trajectory were already being
formulated. Increasing demand by adding additional submarines will require scaling
facility and workforce development plans to operate at a higher rate of production. The
nuclear shipyards would also look to increase material procurement proportionally to the
increased demand. In some cases, the shipyard facilities may be constrained with existing
Congressional Research Service

40

capacity and may look to source additional work in the supply base where capacity exists
or where there are competitive business advantages to be realized. Creating additional
capacity in the supply base will require non-recurring investment in supplier qualification,
facilities, capital equipment and workforce training and development.
Industry is more likely to increase investment in new capability and capacity if there is
certainty that the Navy will proceed with a stable shipbuildin g plan. Positive signals of
commitment from the Government must go beyond a published 30-year Navy Shipbuilding
Plan and line items in the Future Years Defense Plan (FYDP) and should include

Multi-year contracting for Block procurement which provides stability in the industrial base and
encourages investment in facilities and workforce development

Funding for supplier development to support training, qualification, and facilitization efforts—
Electric Boat and Newport News have recommended to the Navy funding of $400M over a three-
year period starting in 2018 to support supplier development for the Submarine Industrial Base as
part of an Integrated Enterprise Plan Extended Enterprise initiative

Acceleration of Advance Procurement and/or Economic Order Quantities (EOQ) procurement
from FY19 to FY18 for Virginia Block V

Government incentives for construction readiness and facilities / special tooling for shipyard and
supplier facilities, which help cash flow capital investment ahead of construction contract awards

Procurement of additional production back-up (PBU) material to help ensure a ready supply of
material to mitigate construction schedule risk. .
So far, this testimony has focused on the Submarine Industrial Base, but the General
Dynamics Marine Systems portfolio also includes surface ship construction. Unlike
Electric Boat, Bath Iron Works and NASSCO are able to support increased demand without
a significant increase in resources.....
Bath Iron Works is well positioned to support the Administration’s announced goal of
increasing the size of the Navy fleet to 355 ships. For BIW that would mean increasing the
total current procurement rate of two DDG 51s per year to as many as four DDGs per year,
allocated equally between BIW and HII. This is the same rate that the surface combatant
industrial base sustained over the first decade of full rate production of the DDG 51 Class
(1989-1999)....
No significant capital investment in new facilities is required to accommodate delivering
two DDGs per year. However, additional funding will be required to train future
shipbuilders and maintain equipment. Current hiring and training processes support the
projected need, and have proven to be successful in the recent past. BIW has invested
significantly in its training programs since 2014 with the restart of the DDG 51 program
and given these investments and the current market in Maine, there is little concern of
meeting the increase in resources required under the projected plans.
A predictable and sustainable Navy workload is essential to justify expanding
hiring/training programs. BIW would need the Navy’s commitment that the Navy’s plan
will not change before it would proceed with additional hiring and training to support
increased production.
BIW’s supply chain is prepared to support a procurement rate increase of up to four DDG
51s per year for the DDG 51 Program. BIW has long-term purchasing agreements in place
for all major equipment and material for the DDG 51 Program. These agreements provide
for material lead time and pricing, and are not constrained by the number of ships ordered
in a year. BIW confirmed with all of its critical suppliers that they can support this
increased procurement rate....
The Navy’s Force Structure Assessment calls for three additional ESBs. Additionaly,
NASSCO has been asked by the Navy and the Congressional Budget Office (CBO) to
evaluate its ability to increase the production rate of T-AOs to two ships per year. NASSCO
has the capacity to build three more ESBs at a rate of one ship per year while building two
Congressional Research Service

41

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

T-AOs per year. The most cost effective funding profile requires funding ESB 6 in FY18
and the following ships in subsequent fiscal years to avoid increased cost resulting from a
break in the production line. The most cost effective funding profile to enable a production
rate of two T-AO ships per year requires funding an additional long lead time equipment
set beginning in FY19 and an additional ship each year beginning in FY20.
NASSCO must now reduce its employment levels due to comp letion of a series of
commercial programs which resulted in the delivery of six ships in 2016. The proposed
increase in Navy shipbuilding stabilizes NASSCO’s workload and workforce to levels that
were readily demonstrated over the last several years.
Some moderate investment in the NASSCO shipyard will be needed to reach this level of
production. The recent CBO report on the costs of building a 355-ship Navy accurately
summarized NASSCO’s ability to reach the above production rate stating, “building more
… combat logistics and support ships would be the least problematic for the shipyards.”62
At the same hearing, Brian Cuccias, president, Ingal s Shipbuilding, Huntington Ingal s Industries
(the country’s other principal builder of Navy ships) stated the following:
Qualifying to be a supplier is a difficult process. Depending on the commodity, it may take
up to 36 months. That is a big burden on some of these small businesses. This is why
creating sufficient volume and exercising early contractual authorization and advance
procurement funding is necessary to grow the supplier base, and not just for traditional
long-lead time components; that effort needs to expand to critical components and
commodities that today are controlling the build rate of submarines and carriers alike.
Many of our suppliers are small businesses and can only make decisions to invest in people,
plant and tooling when they are awarded a purchase order. We need to consider how we
can make commitments to suppliers early enough to ensure material readiness and
availability when construction schedules demand it.
With questions about the industry’s ability to support an increase in shipbuilding, both
Newport News and Ingalls have undertaken an extensive inventory of our suppliers and
assessed their ability to ramp up their capacity. We have engaged many of our key suppliers
to assess their ability to respond to an increase in production.
The fortunes of related industries also impact our suppliers, and an increase in demand
from the oil and gas industry may stretch our supply base. Although some low to moderate
risk remains, I am convinced that our suppliers will be able to meet the forecasted Navy
demand....
I strongly believe that the fastest results can come from leveraging successful platforms on
current hot production lines. We commend the Navy’s decision in 2014 to use the existing
LPD 17 hull form for the LX(R), which will replace the LSD-class amphibious dock
landing ships scheduled to retire in the coming years. However, we also recommend that
the concept of commonality be taken even further to best optimize efficiency, affordability
and capability. Specifically, rather than continuing with a new design for LX(R) within the
“walls” of the LPD hull, we can leverage our hot production line and supply chain and
offer the Navy a variant of the existing LPD design that satisfies the aggressive cost targets
of the LX(R) program while delivering more capability and survivability to the fleet at a
significantly faster pace than the current program. As much as 10-15 percent material
savings can be realized across the LX(R) program by purchasing respective blocks of at
least five ships each under a multi-year procurement (MYP) approach. In the aggregate,
continuing production with LPD 30 in FY18, coupled with successive MYP contracts for

the balance of ships, may yield savings greater than $1 billion across an 11-ship LX(R)
program. Additionally, we can deliver five LX(R)s to the Navy and Marine Corps in the
same timeframe that the current plan would deliver two, helping to reduce the shortfall in
amphibious warships against the stated force requirement of 38 ships.
Multi-ship procurements, whether a formal MYP or a block-buy, are a proven way to
reduce the price of ships. The Navy took advantage of these tools on both Virginia-class
submarines and Arleigh Burke-class destroyers. In addition to the LX(R) program
mentioned above, expanding multi-ship procurements to other ship classes makes sense...
The most efficient approach to lower the cost of the Ford class and meet the goal of an
increased CVN fleet size is also to employ a multi-ship procurement strategy and construct
these ships at three-year intervals. This approach would maximize the material
procurement savings benefit through economic order quantities procurement and provide
labor efficiencies to enable rapid acquisition of a 12-ship CVN fleet. This three-ship
approach would save at least $1.5 billion, not including additional savings that could be
achieved from government-furnished equipment. As part of its Integrated Enterprise Plan,
we commend the Navy’s efforts to explore the prospect of material economic order
quantity purchasing across carrier and submarine programs.63
At the same hearing, Matthew O. Paxton, president, Shipbuilders Council of America (SCA)—a
trade association representing shipbuilders, suppliers, and associated firms—stated the following:
To increase the Navy’s Fleet to 355 ships, a substantial and sustained investment is required
in both procurement and readiness. However, let me be clear: building and sustaining the
larger required Fleet is achievable and our industry stands ready to help achieve that
important national security objective.
To meet the demand for increased vessel construction while sustaining the vessels we
currently have will require U.S. shipyards to expand their work forces and improve their
infrastructure in varying degrees depending on ship type and ship mix – a requirement our
Nation’s shipyards are eager to meet. But first, in order to build these ships in as timely
and affordable manner as possible, stable and robust funding is necessary to sustain those
industrial capabilities which support Navy shipbuilding and ship maintenance and
modernization....
Beyond providing for the building of a 355-ship Navy, there must also be provision to fund
the “tail,” the maintenance of the current and new ships entering the fleet. Target fleet size
cannot be reached if existing ships are not maintained to their full service lives, while
building those new ships. Maintenance has been deferred in the last few years because of
across-the-board budget cuts....
The domestic shipyard industry certainly has the capability and know-how to build and
maintain a 355-ship Navy. The Maritime Administration determined in a recent study on
the Economic Benefits of the U.S. Shipyard Industry that there are nearly 110,000 skilled
men and women in the Nation’s private shipyards building, repairing and maintaining
America’s military and commercial fleets.1 The report found the U.S. shipbuilding
industry supports nearly 400,000 jobs across the country and generates $25.1 billion in
income and $37.3 billion worth of goods and services each year. In fact, the MARAD
report found that the shipyard industry creates direct and induced employment in every
State and Congressional District and each job in the private shipbuilding and repairing
industry supports another 2.6 jobs nationally.
This data confirms the significant economic impact of this manufacturing sector, but also
that the skilled workforce and industrial base exists domestically to build these ships. Long-

term, there needs to be a workforce expansion and some shipyards will need to reconfigure
or expand production lines. This can and will be done as required to meet the need if
adequate, stable budgets and procurement plans are established and sustained for the long-
term. Funding predictability and sustainability will allow industry to invest in facilities and
more effectively grow its skilled workforce. The development of that crit ical workforce
will take time and a concerted effort in a partnership between industry and the federal
government.
U.S. shipyards pride themselves on implementing state of the art training and
apprenticeship programs to develop skilled men and women that can cut, weld, and bend
steel and aluminum and who can design, build and maintain the best Navy in the world.
However, the shipbuilding industry, like so many other manufacturing sectors, faces an
aging workforce. Attracting and retaining the next generatio n shipyard worker for an
industry career is critical. Working together with the Navy, and local and state resources,
our association is committed to building a robust training and development pipeline for
skilled shipyard workers. In addition to repealing sequestration and stabilizing funding the
continued development of a skilled workforce also needs to be included in our national
maritime strategy....
In conclusion, the U.S. shipyard industry is certainly up to the task of building a 355-ship
Navy and has the expertise, the capability, the critical capacity and the unmatched skiled
workforce to build these national assets. Meeting the Navy’s goal of a 355-ship fleet and
securing America’s naval dominance for the decades ahead will require sustained
investment by Congress and Navy’s partnership with a defense industrial base that can
further attract and retain a highly-skilled workforce with critical skill sets. Again, I would
like to thank this Subcommittee for inviting me to testify alongside such distinguished
witnesses. As a representative of our nation’s private shipyards, I can say, with confidence
and certainty, that our domestic shipyards and skilled workers are ready, willing and able
to build and maintain the Navy’s 355-ship Fleet.64
Employment Impact
Building the additional ships that would be needed to achieve and maintain the 355-ship fleet
could create many additional manufacturing and other jobs at shipyards, associated supplier
firms, and elsewhere in the U.S. economy. A 2015 Maritime Administration (MARAD) report
states
Considering the indirect and induced impacts, each direct job in the shipbuilding and
repairing industry is associated with another 2.6 jobs in other parts of the US economy;
each dollar of direct labor income and GDP in the shipbuilding and repairing industry is
associated with another $1.74 in labor income and $2.49 in GDP, respectively, in other
parts of the US economy.65
A March 2017 press report states, “Based on a 2015 economic impact study, the Shipbuilders
Council of America [a trade association for U.S. shipbuilders and associated supplier firms]
believes that a 355-ship Navy could add more than 50,000 jobs nationwide.”66 The 2015

economic impact study referred to in that quote might be the 2015 MARAD study discussed in
the previous paragraph. An estimate of more than 50,000 additional jobs nationwide might be
viewed as a higher-end estimate; other estimates might be lower. A June 14, 2017, press report
states the following: “The shipbuilding industry wil need to add between 18,000 and 25,000 jobs
to build to a 350-ship Navy, according to Matthew Paxton, president of the Shipbuilders Council
of America, a trade association representing the shipbuilding industrial base. Including indirect
jobs like suppliers, the ramp-up may require a boost of 50,000 workers.”67

Appendix D. A Summary of Some Acquisition
Lessons Learned for Navy Shipbuilding
This appendix presents a general summary of lessons learned in Navy shipbuilding, reflecting
comments made repeatedly by various sources over the years. These lessons learned include the
following:
At the outset, get the operational requirements for the program right.
Properly identify the program’s operational requirements at the outset. Manage
risk by not trying to do too much in terms of the program’s operational
requirements, and perhaps seek a so-cal ed 70%-to-80% solution (i.e., a design
that is intended to provide 70%-80% of desired or ideal capabilities). Achieve a
realistic balance up front between operational requirements, risks, and estimated
costs.
Use mature technologies. Use land-based prototyping and testing to bring new
technologies to a high state of maturity before incorporating them into ship
designs, and limit the number of major new technologies to be incorporated into
a new ship design.
Impose cost discipline up front. Use realistic price estimates, and consider not
only development and procurement costs, but life-cycle operation and support
(O&S) costs.
Employ competition where possible in the awarding of design and construction
contracts.
Use a contract type that is appropriate for the amount of risk involved, and
structure its terms to align incentives with desired outcomes.
Minimize design/construction concurrency by developing the design to a high
level of completion before starting construction and by resisting changes in
requirements (and consequent design changes) during construction.
Properly supervise construction work. Maintain an adequate number of
properly trained Supervisor of Shipbuilding (SUPSHIP) personnel.
Provide stability for industry, in part by using, where possible, multiyear
procurement (MYP) or block buy contracting.
Maintain a capable government acquisition workforce that understands what
it is buying, as wel as the above points.
Identifying these lessons is arguably not the hard part—most if not al these points have been
cited for years. The hard part, arguably, is living up to them without letting circumstances lead
program-execution efforts away from these guidelines.

Appendix E. Some Considerations Relating to
Warranties in Shipbuilding Contracts
This appendix presents some considerations relating to warranties in shipbuilding contracts and
other defense acquisition.
In discussions of Navy (and also Coast Guard) shipbuilding, one question that sometimes arises is
whether including a warranty in a shipbuilding contract is preferable to not including one. The
question can arise, for example, in connection with a GAO finding that “the Navy structures
shipbuilding contracts so that it pays shipbuilders to build ships as part of the construction
process and then pays the same shipbuilders a second time to repair the ship when construction
defects are discovered.”68
Including a warranty in a shipbuilding contract (or a contract for building some other kind of
defense end item), while potential y valuable, might not always be preferable to not including
one—it depends on the circumstances of the acquisition, and it is not necessarily a valid criticism
of an acquisition program to state that it is using a contract that does not include a warranty (or a
weaker form of a warranty rather than a stronger one).
Including a warranty general y shifts to the contractor the risk of having to pay for fixing
problems with earlier work. Although that in itself could be deemed desirable from the
government’s standpoint, a contractor negotiating a contract that wil have a warranty wil
incorporate that risk into its price, and depending on how much the contractor might charge for
doing that, it is possible that the government could wind up paying more in total for acquiring the
item (including fixing problems with earlier work on that item) than it would have under a
contract without a warranty.
When a warranty is not included in the contract and the government pays later on to fix problems
with earlier work, those payments can be very visible, which can invite critical comments from
observers. But that does not mean that including a warranty in the contract somehow frees the
government from paying to fix problems with earlier work. In a contract that includes a warranty,
the government wil indeed pay something to fix problems with earlier work—but it wil make
the payment in the less-visible (but stil very real) form of the up-front charge for including the
warranty, and that charge might be more than what it would have cost the government, under a
contract without a warranty, to pay later on for fixing those problems.
From a cost standpoint, including a warranty in the contract might or might not be preferable,
depending on the risk that there will be problems with earlier work that need fixing, the potential
cost of fixing such problems, and the cost of including the warranty in the contract. The point is
that the goal of avoiding highly visible payments for fixing problems with earlier work and the
goal of minimizing the cost to the government of fixing problems with earlier work are separate
and different goals, and that pursuing the first goal can sometimes work against achieving the
second goal.69

, GAO-18-238SP, June 2018, p. 21. A graphic on page 21 shows a GAO finding that the
government was financially responsible for ship builder deficiencies in 96% of the cases examined by GAO, and that
the shipbuilder was financially responsible for shipbuilder deficiencies in 4% of the cases.

Ingalls Industries (HII)—derive about 60% and 96%, respectively, of their revenues from U.S. government work. (See

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

The Department of Defense’s guide on the use of warranties states the following:
Federal Acquisition Regulation (FAR) 46.7 states that “the use of warranties is not
mandatory.” However, if the benefits to be derived from the warranty are commensurate
with the cost of the warranty, the CO [contracting officer] should consider placing it in the
contract. In determining whether a warranty is appropriate for a specific acquisition, FAR
Subpart 46.703 requires the CO to consider the nature and use of the supplies and services,
the cost, the administration and enforcement, trade practices, and reduced requirements.
The rationale for using a warranty should be documented in the contract file....
In determining the value of a warranty, a CBA [cost-benefit analysis] is used to measure
the life cycle costs of the s ystem with and without the warranty. A CBA is required to
determine if the warranty will be cost beneficial. CBA is an economic analysis, which
basically compares the Life Cycle Costs (LCC) of the system with and without the warranty
to determine if warranty coverage will improve the LCCs. In general, five key factors wil
drive the results of the CBA: cost of the warranty + cost of warranty administration +
compatibility with total program efforts + cost of overlap with Contractor support +
intangible savings. Effective warranties integrate reliability, maintainability,
supportability, availability, and life-cycle costs. Decision factors that must be evaluated
include the state of the weapon system technology, the size of the warranted population,
the likelihood that field performance requirements can be achieved, and the warranty
period of performance.70

2016 Annual Report, page 5 of Form 10-K [PDF page 19 of 134]). T hese two shipbuilders operate the only U.S.
shipyards currently capable of building several major types of Navy ships, including submarines, aircraft carriers, large
surface combatants, and amphibious ships. T hus, even if a warranty in a shipbuilding contract with one of these firms
were to somehow mean that the government did not have pay under the terms of that contract —either up front or later
on—for fixing problems with earlier work done under that contract, there would still be a question as to whether the
government would nevertheless wind up eventually paying much of that cost as part of the price of one or more future
contracts the government may have that firm.

Appendix F. Avoiding Procurement Cost Growth vs.
Minimizing Procurement Costs
This appendix presents some considerations relating to avoiding procurement cost growth vs.
minimizing procurement costs in shipbuilding and other defense acquisition.
The affordability chal enge posed by the Navy’s shipbuilding plans can reinforce the strong
oversight focus on preventing or minimizing procurement cost growth in Navy shipbuilding
programs, which is one expression of a strong oversight focus on preventing or minimizing cost
growth in DOD acquisition programs in general. This oversight focus may reflect in part an
assumption that avoiding or minimizing procurement cost growth is always synonymous with
minimizing procurement cost. It is important to note, however, that as paradoxical as it may seem,
avoiding or minimizing procurement cost growth is not always synonymous with minimizing
procurement cost, and that a sustained, singular focus on avoiding or minimizing procurement
cost growth might sometimes lead to higher procurement costs for the government.
How could this be? Consider the example of a design for the lead ship of a new class of Navy
ships. The construction cost of this new design is uncertain, but is estimated to be likely
somewhere between Point A (a minimum possible figure) and Point D (a maximum possible
figure). (Point D, in other words, would represent a cost estimate with a 100% confidence factor,
meaning there is a 100% chance that the cost would come in at or below that level.) If the Navy
wanted to avoid cost growth on this ship, it could simply set the ship’s procurement cost at Point
D. Industry would likely be happy with this arrangement, and there likely would be no cost
growth on the ship.
The alternative strategy open to the Navy is to set the ship’s target procurement cost at some
figure between Points A and D—cal it Point B—and then use that more chal enging target cost to
place pressure on industry to sharpen its pencils so as to find ways to produce the ship at that
lower cost. (Navy officials sometimes refer to this as “pressurizing” industry.) In this example, it
might turn out that industry efforts to reduce production costs are not successful enough to build
the ship at the Point B cost. As a result, the ship experiences one or more rounds of procurement
cost growth, and the ship’s procurement cost rises over time from Point B to some higher
figure—cal it Point C.
Here is the rub: Point C, in spite of incorporating one or more rounds of cost growth, might
nevertheless turn out to be lower than Point D, because Point C reflected efforts by the
shipbuilder to find ways to reduce production costs that the shipbuilder might have put less
energy into pursuing if the Navy had simply set the ship’s procurement cost initial y at Point D.
Setting the ship’s cost at Point D, in other words, may eliminate the risk of cost growth on the
ship, but does so at the expense of creating a risk of the government paying more for the ship than
was actual y necessary. DOD could avoid cost growth on new procurement programs starting
tomorrow by simply setting costs for those programs at each program’s equivalent of Point D.
But as a result of this strategy, DOD could wel wind up leaving money on the table in some
instances—of not, in other words, minimizing procurement costs.
DOD does not have to set a cost precisely at Point D to create a potential risk in this regard. A risk
of leaving money on the table, for example, is a possible downside of requiring DOD to budget
for its acquisition programs at something like an 80% confidence factor—an approach that some
observers have recommended—because a cost at the 80% confidence factor is a cost that is likely
fairly close to Point D.
Congressional Research Service

49

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

Procurement cost growth is often embarrassing for DOD and industry, and can damage their
credibility in connection with future procurement efforts. Procurement cost growth can also
disrupt congressional budgeting by requiring additional appropriations to pay for something
Congress thought it had fully funded in a prior year. For this reason, there is a legitimate public
policy value to pursuing a goal of having less rather than more procurement cost growth.
Procurement cost growth, however, can sometimes be in part the result of DOD efforts to use
lower initial cost targets as a means of pressuring industry to reduce production costs—efforts
that, notwithstanding the cost growth, might be partial y successful. A sustained, singular focus
on avoiding or minimizing cost growth, and of punishing DOD for al instances of cost growth,
could discourage DOD from using lower initial cost targets as a means of pressurizing industry,
which could deprive DOD of a tool for controlling procurement costs.
The point here is not to excuse away cost growth, because cost growth can occur in a program for
reasons other than DOD’s attempt to pressurize industry. Nor is the point to abandon the goal of
seeking lower rather than higher procurement cost growth, because, as noted above, there is a
legitimate public policy value in pursuing this goal. The point, rather, is to recognize that this goal
is not always synonymous with minimizing procurement cost, and that a possibility of some
amount of cost growth might be expected as part of an optimal government strategy for
minimizing procurement cost. Recognizing that the goals of seeking lower rather than higher cost
growth and of minimizing procurement cost can sometimes be in tension with one another can
lead to an approach that takes both goals into consideration. In contrast, an approach that is
instead characterized by a sustained, singular focus on avoiding and minimizing cost growth may
appear virtuous, but in the end may wind up costing the government more.

Appendix G. Size of the Navy and Navy
Shipbuilding Rate

Size of the Navy
Table G-1
shows the size of the Navy in terms of total number of ships since FY1948; the
numbers shown in the table reflect changes over time in the rules specifying which ships count
toward the total. Differing counting rules result in differing totals, and for certain years, figures
reflecting more than one set of counting rules are available. Figures in the table for FY1978 and
subsequent years reflect the battle force ships counting method, which is the set of counting rules
established in the early 1980s for public policy discussions of the size of the Navy.
As shown in the table, the total number of battle force ships in the Navy reached a late-Cold War
peak of 568 at the end of FY1987 and began declining thereafter.71 The Navy fel below 300
battle force ships in August 2003 and remained below 300 ships for the next 16 years. The Navy
briefly returned to a level of 300 ships in early July 2020, for the first time in almost 17 years, and
has since fal en back below 300 ships. As of April 22, 2021, the Navy had 296 battle force ships.
As discussed in Appendix B, historical figures for total fleet size might not be a reliable yardstick
for assessing the appropriateness of proposals for the future size and structure of the Navy,
particularly if the historical figures are more than a few years old, because the missions to be
performed by the Navy, the mix of ships that make up the Navy, and the technologies that are
available to Navy ships for performing missions al change over time, and because the number of
ships in the fleet in an earlier year might itself have been inappropriate (i.e., not enough or more
than enough) for meeting the Navy’s mission requirements in that year.
For similar reasons, trends over time in the total number of ships in the Navy are not necessarily a
reliable indicator of the direction of change in the fleet’s ability to perform its stated missions. An
increasing number of ships in the fleet might not necessarily mean that the fleet’s ability to
perform its stated missions is increasing, because the fleet’s mission requirements might be
increasing more rapidly than ship numbers and average ship capability. Similarly, a decreasing
number of ships in the fleet might not necessarily mean that the fleet’s ability to perform stated
missions is decreasing, because the fleet’s mission requirements might be declining more rapidly
than numbers of ships, or because average ship capability and the percentage of time that ships
are in deployed locations might be increasing quickly enough to more than offset reductions in
total ship numbers.

71 Some publications have stated that the Navy reached a peak of 594 ships at the end of FY1987. T his figure, however,
is the total number of active ships in the fleet, which is not the same as the total number of battle force ships. T he battle
force ships figure is the number used in government discussions of the size of the Navy. In recent years, the total
number of active ships has been larger than the total number of battle force ships. For example, the Naval History and
Heritage Command (formerly the Naval Historical Center) states that as of November 16, 2001, the Navy included a
total of 337 active ships, while the Navy states that as of November 19, 2001, the Navy included a total of 317 battle
force ships. Comparing the total number of active ships in one year to the total number of battle force ships in another
year is thus an apples-to-oranges comparison that in this case overstates the decline since FY1987 in the number of
ships in the Navy. As a general rule to avoid potential statistical distortions, comparisons of the number of ships in the
Navy over time should use, whenever possible, a single counting method.

Source: CRS compilation based on Navy budget data and examination of defense authorization and
appropriation committee and conference reports for each fiscal year. The table excludes nonbattle force ships
that do not count toward the 355-ship goal, such as certain sealift and prepositioning ships operated by the
Military Sealift Command and oceanographic ships operated by agencies such as the National Oceanic a nd
Atmospheric Administration (NOAA).
Notes: (1) The totals shown for FY2006, FY2007, and FY2008, reflect the cancel ation two LCSs funded
in FY2006, another two LCSs funded in FY2007, and an LCS funded in FY2008.
(2) The total shown for FY2012 includes two JHSVs—one that was included in the Navy’s FY2012 budget
submission, and one that was included in the Army’s FY2012 budget submission. Until FY2012, JHSVs were being
procured by both the Navy and the Army. The Army was to procure its fifth and final JHSV in FY2012, and this
ship was included in the Army’s FY2012 budget submission. In May 2011, the Navy and Army signed a
Memorandum of Agreement (MOA) transferring the Army’s JHSVs to the Navy. In the FY2012 DOD
Appropriations Act (Division A of H.R. 2055/P.L. 112-74 of December 23, 2011), the JHSV that was in the
Army’s FY2012 budget submission was funded through the Shipbuilding and Conversion, Navy (SCN)
appropriation account, along with the JHSV that the Navy had included in its FY0212 budget submission. The
four JHSVs that were procured through the Army’s budget prior to FY2012, however, are not included in the
annual totals shown in this table.
(3) The figures shown for FY2019 and FY2020 reflect a Navy decision to show the aircraft carrier CVN-81
as a ship to be procured in FY2020 rather than a ship that was procured in FY2019. Congress, as part of its
action on the Navy’s proposed FY2019 budget, authorized the procurement of CVN -81 in FY2019.

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

Appendix H. Effort in 2019 and 2020 to Develop
New Navy Force-Level Goal
This appendix presents additional background information on the effort in 2019 and 2020 to
develop a new Navy force level goal.72
Navy’s Initial Effort Was Called the Integrated Naval FSA (INFSA)
The effort to develop a new Navy force-level goal began in the Navy with a new FSA that Navy
and Marine Corps officials cal ed the Integrated Naval FSA (INFSA), with the words integrated
naval
intended to signal that this FSA would integrate Marine Corps requirements into the
analytical process more fully than previous FSAs did. Department of the Navy (DON) officials
stated that the INFSA would take into account the Trump Administration’s December 2017
National Security Strategy document and its January 2018 National Defense Strategy document,
both of which put an emphasis on renewed great power competition with China and Russia,73 as
wel as updated information on Chinese and Russian naval and other military capabilities and
recent developments in new technologies, including those related to UVs.74
INFSA May Have Called for a 390/435-Ship Force-level Goal
Press reports and statements from Navy officials suggested that the INFSA was completed in late
2019 or early 2020, and that it may have resulted in a new Navy force-level goal for a fleet of
about 390 manned ships plus about 45 unmanned or optional y manned ships, for a total of about
435 manned and unmanned/optional y manned ships. Navy officials provided few additional
details about the composition of this 390/435-ship force-level goal.75

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

INFSA Results and Associated FY2021 30-Year Shipbuilding Plan
Withheld from Congress
The release to Congress of the new Navy force-level goal resulting from the INFSA was
postponed repeatedly in late 2019 and early 2020.76 Remarks from DOD officials and press
reports indicated that then-Secretary of Defense Mark Esper and officials within the Office of the
Secretary of Defense (OSD) disagreed with some of the INFSA’s assumptions and resulting
conclusions. Coincident with this, OSD reportedly also withheld the release to Congress of the
Navy’s associated FY2021 30-year shipbuilding plan, because Esper and OSD officials
reportedly believed that it did not present a “credible pathway” for achieving a fleet of at least
355 ships in a timely manner.77
INFSA Superseded by DOD’s Future Naval Force Study (FNFS)
The INFSA reportedly was superseded in early 2020 by an OSD-led effort cal ed the Future
Naval Force Study (FNFS) that reportedly involves OSD and the Joint Staff and is being overseen
by Deputy Defense Secretary David Norquist.78 As part of the FNFS, OSD reportedly has used
war games to assess the merits of three candidate fleet plans prepared by the Navy, the Joint Staff,
and the Cost Assessment and Program Evaluation (CAPE) office within OSD. The Hudson
Institute, a private defense and foreign policy think tank, provided an additional study to help

76 T hrough much of 2019, Navy officials stated that the INFSA was to be completed by the end of 2019. A September
27, 2019, press report stated that an interim version was to be completed by September 2019, in time to inform
programmatic decisions on the FY2022 Program Objective Memorandum (POM), meaning the in -house DOD planning
document that will guide the development of DOD’s FY2022 budget submission. (Mallory Shelbourne, “Navy, Marine
Corps Conducting Integrated Force-Structure Assessment,” Inside Defense, September 27, 2019. See also Otto
Kreisher, “New Force Structure Assessment Will Address Needs of ‘Great Power Competition,’ T wo T op
Requirements Officers Say,” Seapower, October 22, 2019, and the section under the subheader “Naval Integrated Force
Structure Assessment” in Megan Eckstein, “Navy Marines W argaming New Gear to Support Emerging Warfare
Concepts,” USNI News, October 23, 2019.)
A December 6, 2019, memorandum from then -Acting Secretary of the Navy T homas Modly stated that he expected the
final INFSA to be published no later than January 15, 2020. (Memorandum for distribution from Acting Secretary of
the Navy T homas B. Modly, subject “SecNav Vector !,” dated December 6, 2019. See also David B. Larter, “Acting
US Navy Secretary: Deliver Me a 355-Ship Fleet by 2030,” Defense News, December 9, 2019.)
A January 23, 2020, press report quoted Modly as saying that the January 15 date was an internal Navy deadline, and
that the Navy expected the INFSA to be released to outside audiences sometime during the spring of 2020. (Mallory
Shelbourne, “Modly: Navy Expects to Release FSA by Spring,” Inside Defense, January 23, 2020.)

inform DOD’s work.79 With the INFSA having been superseded by the FNFS, the Navy
reportedly “has lost much of its power on deciding what its future fleet wil look like….”80 No
release date for the result of the FNFS has been announced, but press reports suggest that much of
the analytical work on the FNFS has now been completed, and that the results of the FNFS could
be released in coming days or weeks.81
April and June 2020 Press Reports About FNFS Results
April and June 2020 press reports stated that FNFS as of April 2020 was moving toward
recommending a fleet with, among other things, 68 or 69 nuclear-powered attack submarines
(SSNs), 9 aircraft carriers, 80 to 90 large surface combatants (i.e., cruisers and destroyers), 55 to
70 smal surface combatants (i.e., frigates and Littoral Combat Ships [LCSs]), 65 unmanned or
lightly manned surface vehicles, and 50 extra-large unmanned underwater vehicles (XLUUVs).82
September 2020 Press Reports About FNFS Studies
A September 24, 2020, press report about studies done in April in support of the FNFS stated
The Pentagon’s upcoming recommendation for a future Navy is expected to call for a
significant increase in the number of ships, with officials discussing a fleet as large as 530
hulls, according to documents obtained by Defense News.
Supporting documents to the forthcoming Future Navy Force Study reviewed by Defense
News show the Navy moving towards a lighter force with many more ships but fewer
aircraft carriers and large surface combatants. Instead, the fleet would include more smal
surface combatants, unmanned ships and submarines and an expanded logistics force.
Two groups commissioned by Secretary of Defense Mark Esper to design what a future
Navy should look like suggested fleets of anywhere from 480 to 534 ships, when manned
and unmanned platforms are accounted for—at least a 35 percent increase in fleet size from
the current target of 355 manned ships by 2030.
The numbers all come from an April draft of inputs to the Future Navy Force Study
conducted by the Office of the Secretary of Defense. While the number will likely have
changed somewhat in final recommendations recently sent to Esper, the plans being
discussed in April are notable as they reflect what will likely be major shift in the Navy’s
future—and the expectation is that a larger-than-planned Navy based on the concepts laid
out in the documents will remain intact in the final analysis….
The Future Naval Force Study, overseen by Deputy Secretary of Defense David Norquist,
kicked off in January after Esper decided he wanted an outside take on the Navy’s self-
review of its future force structure. The OSD-led review tasked three groups to provide
their version of an ideal fleet construction for the year 2045, one each by the Pentagon’s

Cost Assessment & Program Evaluation office, the Joint Staff, the Navy and a group from
the Hudson Institute.
Those fleets were war-gamed and the results were compiled into the Future Naval Force
Study, which was briefed to Esper earlier this month….
The April documents viewed by Defense News included notional fleets designed by CAPE
and the Hudson Institute….
The fleets designed by the CAPE and Hudson teams agreed on the need to increase the
number and diversity of ships while boosting vertical launch system capacity—while also
holding the operations and sustainment cost of the fleet as steady as possible and avoid
adding to the number of sailors required to operate it.
As of the April drafts, both the CAPE and Hudson Institute teams were supportive of
shrinking the number of supercarriers to nine from the current 11, which would effectively
give the country eight active carriers, with one carrier always in midlife overhaul and
refueling. The Hudson study also called for investing in four light carriers.
The CAPE fleet called for between 80 and 90 large surface combatants, about the same
level as today’s 89 cruisers and destroyers. Hudson looked to reduce the number slightly
and instead fund more lightly manned corvettes, something Hudson has called for in the
past.
The reports called for between 65 and 87 large unmanned surface vessels or optionaly
unmanned corvettes, which the Navy hopes will boost vertical launch system capacity to
offset the loss over time of the Arleigh Burke-class destroyers and the four guided missile
submarines.
Both fleets called for increased small surface combatants, with the CAPE study putting the
upper limit at 70 ships. Hudson recommended a maximum of 56. The Navy’s 2016 Force
Structure Assessment called for 52 small surface combatants.
Both fleets also favored a slight increase in attack submarines over the current 66-ship
requirement but reflected a big boost in large unmanned submarines, anywhere between
40 and 60 total. The idea would be to get the Extra Large Unmanned Underwater Vehicle
to do monotonous surveillance missions or highly dangerous missions, freeing up the more
complex manned platforms for other tasking.
On the amphibious side, both fleets reduced the overall number of traditional dock landing
ships, such as the LPD-17, from the current 23 to between 15 and 19. As for the big-deck
amphibious ships, CAPE favored holding at the current level of 10, while Hudson favored
cutting to five, with the savings reinvested towards four light carriers.
The studies called for between 20 and 26 of the Marines’ light amphibious warships, which
they need for ferrying Marines and gear around islands in the Pacific.
Both fleets significantly expanded the logistics force, with big increases coming from
smaller ships similar to offshore or oil platform support-type vessels. The fleets called for
anywhere from 19 to 30 “future small logistics” ships. The CAPE and Hudon fleets
increased the number of fleet oilers anywhere from 21 to 31, up from today’s 17….
The Hudson fleet called for a significant boost to the command and support ship
infrastructure from today’s 33 ships to 52 ships. CAPE called for the fleet to remain about
the same. Those ships include dry cargo ships, the expeditionary fast transports,
expeditionary transfer docks and expeditionary sea bases.

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

All told, the fleets posited between 316 and 358 “traditional” ships, but when new classes
and unmanned ships were lumped in, the fleet designs contained upwards of 500 ships or
more.83
A September 25, 2020, press report similarly stated that the Hudson Institute study cal ed for a
Navy with 434 manned ships and 139 large UVs, including, among other things, 60 nuclear-
powered attack submarines (SSNs), 9 aircraft carriers, 80 corvettes, 26 Light Amphibious
Warships (LAWs), 99 medium unmanned surface vessels (MUSVs), and 40 extra-large unmanned
underwater vehicles (XLUUVs).84
June 2020 Testimony from Hudson Institute
At a June 4, 2020, hearing on hearing on future force structure requirements for the Navy before
the Seapower and Projection Forces subcommittee of the House Armed Services Committee, one
of the witnesses, Bryan Clark of the Hudson Institute, presented testimony that proposed a fleet of
473 manned ships and 152 large UVs, including 12 bal istic missile submarines; 61 SSNs; 10
large-deck, nuclear-powered aircraft carriers (CVNs); 77 large surface combatants (i.e., cruisers
and destroyers); 52 smal surface combatants (i.e., frigates and Littoral Combat Ships); 91
corvettes; 33 larger amphibious ships, including 9 large-deck (LHD/LHA-type) ships and 24
smal -deck (LPD-type) ships; 27 smal er Light Amphibious Warships (LAWs); 39 larger resupply
ships (including 20 oilers); 20 smal er oilers; 51 command and support ships; 112 MUSVs; and
40 XLUUVs.85
October 2020 Report from Hudson Institute
An October 2020 report by the Hudson Institute on future Navy force structure presented a
revised set of force-level goals, recommending a fleet of 442 manned ships and 139 large UVs,
including 12 bal istic missile submarines; 60 SSNs; 9 large-deck, nuclear-powered aircraft
carriers (CVNs); 64 large surface combatants (i.e., cruisers and destroyers); 52 smal surface
combatants (i.e., frigates and Littoral Combat Ships); 80 corvettes; 30 larger amphibious ships,
including 8 large-deck (LHD/LHA-type) ships and 22 smal -deck (LPD-type) ships; 26 smal er
Light Amphibious Warships (LAWs); 38 larger resupply ships; 18 smal er oilers; 53 command
and support ships; 99 MUSVs; and 40 XLUUVs.86
