Navy LPD-17 Flight II and LHA Amphibious Ship Programs

Summary
The Navy wants to procure a total of 13 LPD-17 Flight II amphibious ships. LPD-17 Flight II
ships cost roughly $1.8 billion each to procure. The first LPD-17 Flight II ship, LPD-30, was
procured in FY2018. As part of its action on the Navy’s proposed FY2019 budget, Congress
provided $350 million in unrequested advance procurement (AP) funding for a second LPD-17
Flight II ship, LPD-31, to be procured in FY2020. This was consistent with the Navy’s FY2019
budget submission, under which LPD-31 was planned for procurement in FY2020 and the
remainder of its procurement cost was to be requested in FY2020. The Navy’s FY2020 budget
submission, however, proposes deferring the procurement of LPD-31 by one year, to FY2021,
and the Navy’s proposed FY2020 budget, rather than requesting the remainder of LPD-31’s
procurement cost, instead requests $247.1 million in AP funding for the ship.
Navy officials state that if no LPD-17 Flight II ship is procured in FY2020, the $350 million in
FY2019 AP funding that Congress provided for the LPD-17 program would become
unexecutable, because that funding was provided specifically for use in building an LPD-17
Flight II ship procured in FY2020, not an LPD-17 Flight II ship procured in FY2021. The $350
million in FY2019 AP funding can be made executable by procuring LPD-31 in FY2020 or by
passing legislation permitting the FY2019 AP funding to be used for an LPD-17 Flight II ship
procured in FY2021. One alternative for procuring LPD-31 in FY2020 would be to do so with
full funding (i.e., with the remainder of the ship’s procurement cost provided in FY2020).
Another alternative would be to pass legislation giving the Navy the authority to procure LPD-31
in FY2020 using incremental funding. Navy officials state that under the latter alternative, the
amount of procurement funding needed for LPD-31 in FY2020 would be, at a minimum, roughly
$200 million, and not more than the requested amount of $247.1 million.
As part of its action on the Navy’s proposed FY2019 budget, Congress also provided $350
million in unrequested AP funding for a different kind of amphibious ship—an amphibious
assault ship called LHA-9. This ship is considerably larger and more expensive than an LPD-17
Flight II ship. The Navy’s FY2020 budget submission estimates LHA-9’s procurement cost at
$4,076.4 million (i.e., about $4.1 billion). Under the Navy’s FY2019 budget submission, LHA-9
was planned for procurement in FY2024. The $350 million in FY2019 AP funding that Congress
provided was intended to encourage the Navy to accelerate the procurement of LHA-9 from
FY2024 to an earlier fiscal year, such as FY2020 or FY2021. Under the Navy’s FY2020 budget
submission, the Navy continues to show LHA-9 as a ship planned for procurement in FY2024,
and the Navy’s proposed FY2020 budget does not request any additional procurement or AP
funding for the ship.
Issues for Congress include whether to procure LPD-31 in FY2020 or FY2021; whether to
procure LPD-31 (if it is procured in FY2020) with full funding or incremental funding; the
amount of procurement or AP funding to provide for LPD-31 and LHA-9 in FY2020; more
generally whether the Navy is placing too much, too little, or about the right amount of emphasis
on amphibious ships in its FY2020 budget submission, particularly compared to other Navy
shipbuilding programs; whether the Navy’s next Force Structure Assessment (FSA) will change
the required number of amphibious ships, and if so, whether and how that might change the
required number of LPD-17 Flight II ships; and technical and cost risk in the LPD-17 Flight II
and LHA programs.

Navy LPD-17 Flight II and LHA Amphibious Ship Programs

Introduction
This report provides background information and issues for Congress on the Navy’s LPD-17
Flight II and LHA amphibious ship programs. The Navy’s FY2020 budget submission defers the
planned procurement of the second LPD-17 Flight II ship, LPD-31, by one year, to FY2021, and
requests $247.1 million in advance procurement (AP) funding for the ship. The Navy wants to
procure the next LHA-type amphibious assault ship in FY2024. The Navy’s proposed FY2020
budget does not request any procurement or AP funding for this ship.
Issues for Congress include whether to procure LPD-31 in FY2020 or FY2021; whether to
procure LPD-31 (if it is procured in FY2020) with full funding or incremental funding; the
amount of procurement or AP funding to provide for LPD-31 and LHA-9 in FY2020; and more
generally whether the Navy is placing too much, too little, or about the right amount of emphasis
on amphibious ships in its FY2020 budget submission, particularly compared to other Navy
shipbuilding programs. Congress’s decisions on these issues could affect Navy capabilities and
funding requirements and the shipbuilding industrial base.
For an overview of the strategic and budgetary context in which amphibious ship and other Navy
shipbuilding programs may be considered, see CRS Report RL32665, Navy Force Structure and
Shipbuilding Plans: Background and Issues for Congress, by Ronald O'Rourke.
Background
Amphibious Ships in General
Roles and Missions
Navy amphibious ships are operated by the Navy, with crews consisting of Navy personnel. The
primary function of Navy amphibious ships is to lift (i.e., transport) embarked U.S. Marines and
their equipment and supplies to distant operating areas, and enable Marines to conduct
expeditionary operations ashore in those areas. Although amphibious ships are designed to
support Marine landings against opposing military forces, they are also used for operations in
permissive or benign situations where there are no opposing forces. Due to their large storage
spaces and their ability to use helicopters and landing craft to transfer people, equipment, and
supplies from ship to shore without need for port facilities,1 amphibious ships are potentially
useful for a range of combat and noncombat operations.2

1 Amphibious ships have berthing spaces for Marines; storage space for their wheeled vehicles, their other combat
equipment, and their supplies; flight decks and hangar decks for their helicopters and vertical take-off and landing
(VTOL) fixed-wing aircraft; and well decks for storing and launching their landing craft. (A well deck is a large,
garage-like space in the stern of the ship. It can be flooded with water so that landing craft can leave or return to the
ship. Access to the well deck is protected by a large stern gate that is somewhat like a garage door.)
2 Amphibious ships and their embarked Marine forces can be used for launching and conducting humanitarian-
assistance and disaster-response (HA/DR) operations; peacetime engagement and partnership-building activities, such
as exercises; other nation-building operations, such as reconstruction operations; operations to train, advise, and assist
foreign military forces; peace-enforcement operations; noncombatant evacuation operations (NEOs); maritime-security
operations, such as anti-piracy operations; smaller-scale strike and counter-terrorism operations; and larger-scale
ground combat operations. Amphibious ships and their embarked Marine forces can also be used for maintaining
forward-deployed naval presence for purposes of deterrence, reassurance, and maintaining regional stability.

On any given day, some of the Navy’s amphibious ships, like some of the Navy’s other ships, are
forward-deployed to various overseas operating areas. Forward-deployed U.S. Navy amphibious
ships are often organized into three-ship formations called amphibious ready groups (ARGs).3 On
average, two or perhaps three ARGs might be forward-deployed at any given time. Amphibious
ships are also sometimes forward-deployed on an individual basis to lower-threat operating areas,
particularly for conducting peacetime engagement activities with foreign countries or for
responding to smaller-scale or noncombat contingencies.
Types of Amphibious Ships
Navy amphibious ships can be divided into two main groups—the so-called “big-deck”
amphibious assault ships, designated LHA and LHD, which look like medium-sized aircraft
carriers, and the smaller (but still sizeable) amphibious ships designated LPD or LSD, which are
sometimes called “small-deck” amphibious ships.4 The LHAs and LHDs have large flight decks
and hangar decks for embarking and operating numerous helicopters and vertical or short takeoff
and landing (V/STOL) fixed-wing aircraft, while the LSDs and LPDs have much smaller flight
decks and hangar decks for embarking and operating smaller numbers of helicopters. The LHAs
and LHDs, as bigger ships, in general can individually embark more Marines and equipment than
the LSDs and LPDs.
Amphibious Lift Goal
Current Goal
The Navy’s 355-ship force-level goal, released in December 2016, calls for achieving and
maintaining a 38-ship amphibious force that includes 12 LHA/LHD-type ships, 13 LPD-17 class
ships, and 13 LSD/LPD-type ships (12+13+13).5 The goal for achieving and maintaining a force
of 38 amphibious ships relates primarily to meeting wartime needs for amphibious lift. Navy and
Marine Corps officials have testified that fully meeting U.S. regional combatant commander
requests for day-to-day forward deployments of amphibious ships would require a force of 50 or
more amphibious ships.6

3 An ARG notionally includes three amphibious ships—one LHA or LHD, one LSD, and one LPD. These three
amphibious ships together can embark a Marine expeditionary unit (MEU) consisting of about 2,200 Marines, their
aircraft, their landing craft, their combat equipment, and about 15 days’ worth of supplies. ARGs can operate in
conjunction with carrier strike groups (CSGs) to form larger naval task forces; ARGs can also be broken up into
individual ships that are sent to separate operating areas.
4 U.S. Navy amphibious ships have designations starting with the letter L, as in amphibious landing. LHA can be
translated as landing ship, helicopter-capable, assault; LHD can be translated as landing ship, helicopter-capable, well
deck; LPD can be translated as landing ship, helicopter platform, well deck; and LSD can be translated as landing ship,
well deck. Whether noted in the designation or not, almost all these ships have well decks. The exceptions are LHAs 6
and 7, which do not have well decks and instead have expanded aviation support capabilities. For an explanation of
well decks, see footnote 1.

Plans: Background and Issues for Congress, by Ronald O'Rourke. For a more detailed review of the 38-ship force
structure requirements, see Appendix A of CRS Report RL34476, Navy LPD-17 Amphibious Ship Procurement:

Navy LPD-17 Flight II and LHA Amphibious Ship Programs

Potential Change in Goal
The Navy’s ship force-level goals, including its force-level goal for amphibious ships, are
determined in a Navy analysis called a Force Structure Assessment (FSA). The Navy conducts a
new FSA (or updates the most recent FSA) once every few years. The Navy is currently
conducting a new FSA to succeed the one whose results were released in December 2016. Navy
officials have stated that the new FSA will be completed by the end of 2019.7 Statements from the
Commandant of the Marine Corps suggest that the new FSA might change the Navy’s
amphibious ship force to an architecture based on a new amphibious lift target and a new mix of
amphibious ships.
The current 38-ship amphibious ship force-level goal is intended to meet a requirement for having
enough amphibious lift to lift the assault echelons of two Marine Expeditionary Brigades
(MEBs), a requirement known as the 2.0 MEB lift requirement. The 2.0 MEB lift requirement
dates to 2006. The translation of this lift requirement into a Marine Corps-preferred force-level
goal of 38 ships dates to 2009, and the Navy’s formal incorporation of the 38-ship goal (rather
than a more fiscally constrained goal of 33 or 34 ships) into the Navy’s overall ship force-
structure goal dates to the 2016 FSA, the results of which were released in December 2016.8
In July 2019, General David H. Berger, the Commandant of the Marine Corps, released a
document entitled Commandant’s Planning Guidance that states that the Marine Corp wants to,
among other things, move away from the 38-ship amphibious ship force-level goal and the 2.0
MEB lift force-planning metric, and shift to a new and different mix of amphibious ships that
includes not only LHA/LHD-type amphibious assault ships and LPD/LPD-type amphibious
ships, but other kinds of ships as well, including smaller amphibious ships, ships like the Navy’s
Expeditionary Sea Base (ESB) and Expeditionary Fast Transport (EPF) ships, ships based on
commercial-ship hull designs, and unmanned surface vehicles (USVs). The Commandant’s
Planning Guidance, which effectively announces a once-in-a-generation change in Marine Corps
thinking on this and other issues relating to the Marine Corps, states in part (emphasis as in the
original):
Our Nation’s ability to project power and influence beyond its shores is increasingly
challenged by long-range precision fires; expanding air, surface, and subsurface threats;
and the continued degradation of our amphibious and auxiliary ship readiness. The ability
to project and maneuver from strategic distances will likely be detected and contested from
the point of embarkation during a major contingency. Our naval expeditionary forces must
possess a variety of deployment options, including L-class [amphibious ships] and E-class
[expeditionary ships] ships, but also increasingly look to other available options such as
unmanned platforms, stern landing vessels, other ocean-going connectors, and smaller
more lethal and more risk-worthy platforms. We must continue to seek the affordable
and plentiful at the expense of the exquisite and few when conceiving of the future
amphibious portion of the fleet.
We must also explore new options, such as inter-theater connectors and commercially
available ships and craft that are smaller and less expensive, thereby increasing the
affordability and allowing acquisition at a greater quantity. We recognize that we must
distribute our forces ashore given the growth of adversary precision strike capabilities, so

ships is “close to 54.” (Source: Spoken testimony of Lieutenant General Glueck, as reflected in transcript of hearing.)

it would be illogical to continue to concentrate our forces on a few large ships. The
adversary will quickly recognize that striking while concentrated (aboard ship) is the
preferred option. We need to change this calculus with a new fleet design of smaller, more
lethal, and more risk-worthy platforms. We must be fully integrated with the Navy to
develop a vision and a new fleet architecture that can be successful against our peer
adversaries while also maintaining affordability. To achieve this difficult task, the Navy
and Marine Corps must ensure larger surface combatants possess mission agility across sea
control, littoral, and amphibious operations, while we concurrently expand the quantity of
more specialized manned and unmanned platforms….
We will no longer use a “2.0 MEB requirement” as the foundation for our arguments
regarding amphibious ship building, to determine the requisite capacity of vehicles
or other capabilities, or as pertains to the Maritime Prepositioning Force. We will no
longer reference the 38-ship requirement memo from 2009, or the 2016 Force
Structure Assessment, as the basis for our arguments and force structure
justifications. The ongoing 2019 Force Structure Assessment will inform the amphibious
requirements based upon this guidance. The global options for amphibs [types of
amphibious ships] include many more options than simply LHAs, LPDs, and LSDs. I will
work closely with the Secretary of the Navy and Chief of Naval Operations (CNO) to
ensure there are adequate numbers of the right types of ships, with the right capabilities, to
meet national requirements.
I do not believe joint forcible entry operations (JFEO) are irrelevant or an operational
anachronism; however, we must acknowledge that different approaches are required given
the proliferation of anti-access/area denial (A2AD) threat capabilities in mutually contested
spaces. Visions of a massed naval armada nine nautical miles off-shore in the South China
Sea preparing to launch the landing force in swarms of ACVs [amphibious combat
vehicles], LCUs [utility landing craft], and LCACs [air-cushioned landing craft]are
impractical and unreasonable. We must accept the realities created by the proliferation of
precision long-range fires, mines, and other smart-weapons, and seek innovative ways to
overcome those threat capabilities. I encourage experimentation with lethal long-range
unmanned systems capable of traveling 200 nautical miles, penetrating into the adversary
enemy threat ring, and crossing the shoreline—causing the adversary to allocate resources
to eliminate the threat, create dilemmas, and further create opportunities for fleet maneuver.
We cannot wait to identify solutions to our mine countermeasure needs, and must make
this a priority for our future force development efforts….
Over the coming months, we will release a new concept in support of the Navy’s
Distributed Maritime Operations (DMO) Concept and the NDS called – Stand-in Forces.
The Stand-in Forces concept is designed to restore the strategic initiative to naval forces
and empower our allies and partners to successfully confront regional hegemons that
infringe on their territorial boundaries and interests. Stand-in Forces are designed to
generate technically disruptive, tactical stand-in engagements that confront aggressor
naval forces with an array of low signature, affordable, and risk-worthy platforms
and payloads. Stand-in forces take advantage of the relative strength of the contemporary
defense and rapidly-emerging new technologies to create an integrated maritime defense
that is optimized to operate in close and confined seas in defiance of adversary long-range
precision “stand-off capabilities.”
Creating new capabilities that intentionally initiate stand-in engagements is a disruptive
“button hook” in force development that runs counter to the action that our adversaries
anticipate. Rather than heavily investing in expensive and exquisite capabilities that
regional aggressors have optimized their forces to target, naval forces will persist forward
with many smaller, low signature, affordable platforms that can economically host a dense
array of lethal and nonlethal payloads.

By exploiting the technical revolution in autonomy, advanced manufacturing, and artificial
intelligence, the naval forces can create many new risk-worthy unmanned and minimally-
manned platforms that can be employed in stand-in engagements to create tactical
dilemmas that adversaries will confront when attacking our allies and forces forward.9
Current and Projected Force Levels
The Navy’s force of amphibious ships at the end of FY2018 included 32 ships, including 9
amphibious assault ships (1 LHA and 8 LHDs), 11 LPD-17 Flight I ships, and 12 LSD-41/49
class ships. The LSD-41/49 class ships, which are the ships to be replaced by LPD-17 Flight II
ships, are discussed in the next section.
The Navy’s FY2020 30-year (FY2020-FY2049) shipbuilding plan projects that the Navy’s force
of amphibious ships will increase gradually to 38 ships by FY2026, remain at a total of 36 to 38
ships in FY2027 to FY2034, decline to 34 or 35 ships in FY2035-FY2038, increase to 36 or 37
ships in FY2039-FY2046, and remain at 35 ships in FY2047-FY2049. Over the entire 30-year
period, the force is projected to include an average of about 35.8 ships, or about 94% of the
required figure of 38 ships, although the resulting amount of lift capability provided by the ships
would not necessarily equate to about 94% of the amphibious lift goal, due to the mix of ships in
service at any given moment and their individual lift capabilities.
Existing LSD-41/49 Class Ships
The Navy’s 12 aging Whidbey Island/Harpers Ferry (LSD-41/49) class ships (Figure 1) were
procured between FY1981 and FY1993 and entered service between 1985 and 1998.10 The class
includes 12 ships because they were built at a time when the Navy was planning a 36-ship
(12+12+12) amphibious force. They have an expected service life of 40 years; the first ship will

10 The class was initially known as the Whidbey Island (LSD-41) class. The final four ships in the class, beginning with
Harpers Ferry (LSD-49), were built to a modified version of the original LSD-41 design, prompting the name of the
class to be changed to the Harpers Ferry/Whidbey Island (LSD-41/49) class. Some sources refer to these 12 ships as
two separate classes. The first three were built by Lockheed Shipbuilding of Seattle, WA, a firm that subsequently
exited the Navy shipbuilding business. The final nine were built by Avondale Shipyards of New Orleans, LA, a
shipyard that eventually became part of the shipbuilding firm Huntington Ingalls Industries (HII). Avondale, like
Lockheed Shipbuilding, no longer builds Navy ships. HII wound down Navy shipbuilding operations at Avondale in
2014, after Avondale finished building LPD-25, the ninth LPD-17 class ship. HII continues to operate two other
shipyards that build Navy ships—Ingalls Shipbuilding in Pascagoula, MS (HII/Ingalls), and Newport News
Shipbuilding in Newport News, VA (HII/NNS). HII’s construction of amphibious ships, previously divided between
Avondale and Ingalls, now takes place primarily at Ingalls.

reach that age in 2025. The Navy’s FY2020 30-year shipbuilding plan projects that the 12 ships
will retire between FY2026 and FY2038.
LPD-17 Flight II Program
Program Name
The Navy decided in 2014 that the LSD-41/49 replacement ships would be built to a variant of
the design of the Navy’s San Antonio (LPD-17) class amphibious ships. (A total of 13 LPD-17
class ships [LPDs 17 through 29] were procured between FY1996 and FY2017.) Reflecting that
decision, the Navy announced on April 10, 2018, that the replacement ships would be known as
the LPD-17 Flight II ships.11 By implication, the Navy’s original LPD-17 design became the
LPD-17 Flight I design.

11 Megan Ecsteain, “Navy Designates Upcoming LX(R) Amphibs as San Antonio-Class LPD Flight II,” USNI News,
April 11, 2018. Within a program to build a class of Navy ships, the term flight refers to a group of ships within the
class that are built to a particular version of the class design. The LPD-17 Fight II program was previously known as
the LX(R) program. In the designation LX(R), the X meant that the exact design of the ship had not yet been
determined, and the R meant that the ships are intended as replacements for the LSD-41/49 class ships. Prior to being
referred to as the LX(R) program, the program was referred to as the LSD(X) program, meaning an LSD-type ship
whose design had not yet been determined. The program’s designation was changed to LX(R) in 2012 to signal that the
replacement for the existing LSD-41/49 class ships would be an amphibious ship that would best meet future Navy and
Marine Corps needs, regardless of whether that turned out to be a ship that one might refer to as an LSD. For an article
discussing this earlier change in the program’s designation, see Christopher P. Cavas, “Different Missions Might Await
New USN Amphib,” Defense News, November 12, 2012.

The first LPD-17 Flight II ship is designated LPD-30. Subsequent LPD-17 Flight II ships are to
be designated LPD-31, LPD-32, and so on. Whether the LPD-17 Flight II ships constitute their
own shipbuilding program or an extension of the original LPD-17 shipbuilding program might be
a matter of perspective. As a matter of convenience, this CRS report refers to the Flight II
shipbuilding effort as a separate program. Years from now, LPD-17 Flight I and Flight II ships
might come to be known collectively as either the LPD-17 class, the LPD-17/30 class, or the
LPD-17 and LPD-30 classes.
On October 10, 2019, the Navy announced that LPD-30, the first LPD-17 Flight II ship, will be
named Harrisburg, for the city of Harrisburg, PA.12 As a consequence, LPD-17 Flight II, if treated
as a separate class, would be referred to as Harrisburg (LPD-30) class ships.
Design
Compared to the LPD-17 Flight I design, the LPD-17 Flight II design (Figure 2) is somewhat
less expensive to procure, and in some ways less capable—a reflection of how the Flight II design
was developed to meet Navy and Marine Corps operational requirements while staying within a
unit procurement cost target that had been established for the program.13 In many other respects,
however, the LPD-17 Flight II design is similar in appearance and capabilities to the LPD-17
Flight I design. Of the 13 LPD-17 Flight I ships, the final two (LPDs 28 and 29) incorporate some
design changes that make them transitional ships between the Flight I design and the Flight II
design.
Procurement Quantity
Consistent with the Navy’s 38-ship amphibious force-level goal, the Navy wants to procure a
total of 13 LPD-17 Flight II ships.
Procurement Schedule
Overview
The first LPD-17 Flight II ship (LPD-30) was procured in FY2018. Under the Navy’s FY2020
budget submission, the Navy wants to procure the second LPD-17 Flight II ship (LPD-31) in
FY2021, the third (LPD-32) in FY2023, and the remaining 10 (LPDs 33 through 42) at a rate of
one per year during the period FY2025-FY2034.

12 Secretary of the Navy Public Affairs, “SECNAV Names Future Amphibious Transport Dock Ship in Honor of the
city of Harrisburg, Pennsylvania,” Navy News Service, October 10, 2019.
13 The Navy’s unit procurement cost targets for the LPD-17 Flight II program were $1,643 million in constant FY2014
dollars for the lead ship, and an average of $1,400 million in constant FY2014 dollars for ships 2 through 11. (Source:
Navy briefing on LX(R) program to CRS and CBO, March 23, 2015.) The cost target for the lead ship was greater than
the cost target for the subsequent ships primarily because the procurement cost of the lead ship incorporates much or all
of the detail design and nonrecurring engineering (DD/NRE) costs for the program. Incorporating much or all of the
DD/NRE costs of for a shipbuilding program into the procurement cost of the lead ship in the program is a traditional
Navy shipbuilding budgeting practice.

Under the Navy’s FY2019 budget submission, LPD-31 was to be procured in FY2020,14 and the
remaining 11 LPD-17 Flight II ships (LPDs 32 through 42) were to be procured at a rate of one
per year starting in FY2022. Thus, as shown in Table 1, compared to the Navy’s FY2019 budget
submission, the Navy’s FY2020 budget submission proposes deferring the procurement of LPD-
31 by one year, from FY2020 to FY2021; the procurement LPD-32 by one year, from FY2022 to
FY2023; and the procurement of LPD-33 by two years, from FY2023 to FY2025. Consequently,
as shown in Table 1, compared to the Navy’s FY2019 budget submission, the Navy’s FY2020
budget submission reduces from four to two the total number of LPD-17 Flight II ships to be
procured during the period FY2020-FY2024.

14 The Navy had planned to procure the first LPD-17 Flight II ship in FY2020. Congress, as part of its action on the
Navy’s proposed FY2018 budget, accelerated the procurement of the first LPD17 Flight II ship to FY2018. The Navy’s
FY2019 budget submission, which was submitted before Congress finalized its action on the Navy’s FY2018 budget,
programmed the procurement of an LPD-17 Flight II ship in FY2020. Under the Navy’s original plan, the ship
programmed for procurement in FY2020 was to be the first Flight II ship. With the first Flight II ship having been
procured in FY2018, the Flight II ship scheduled for procurement in FY2020 became the second Flight II ship.

The FY2020 budget submission’s reduction (compared to the FY2019 budget submission) of the
number of LPD-17 Flight II ships to be procured during the period FY2020-FY2024 has
increased the estimated procurement costs of the LPD-17 Flight II ships to be procured in those
years due to a reduction in estimated production learning curve benefits in moving from
construction of one ship to the next. The reduction in the number of LPD-17 Flight II ships to be
procured in FY2020-FY2024 has also reduced the potential for using multiyear contracting (i.e.,
either multiyear procurement [MYP] or block buy contracting) to reduce the procurement costs of
these ships. A June 26, 2019, Navy information paper states the following:
The reduction of LPDs in the PB20 [President’s Budget for FY2020—i.e., the FY2020
budget submission] [procurement] profile will result in a loss of [production] learning
[curve benefits] because the construction of ships at the optimal 18 month centers will
extend to approximately 24 month centers. The loss of potential MYP and EOQ [Economic
Order Quantity] savings15 will increase material costs and eliminate other efficiencies. All
of these factors combined will result in an estimated 6% increase [in procurement cost]
from the PB19 request.16
Procurement Cost
Under the Navy’s FY2020 budget submission, LPD-17 Flight II ships cost roughly $1.8 billion
each to procure.
Program Funding

LHA-9 Amphibious Assault Ship
The most recently procured LHA/LHD-type amphibious assault ship is LHA-8 (Figure 3), which
was procured in FY2017 and is scheduled under the Navy’s FY2020 budget submission to be
delivered in January 2024.

15 EOQ purchases—up-front batch orders of selected components of the end items (in this case, ships) that are to be
procured over the course of a multiyear contract are one of the ways that multiyear contracts can reduce procurement
costs. For more on multiyear contracting in defense procurement, see CRS Report R41909, Multiyear Procurement
(MYP) and Block Buy Contracting in Defense Acquisition: Background and Issues for Congress, by Ronald O'Rourke
and Moshe Schwartz.

The Navy wants to procure the next LHA/LHD-type ship, LHA-9, in FY2024. LHA/LHD-type
ships are considerably larger and more expensive than LPDs. The Navy’s FY2020 budget
submission estimates LHA-9’s procurement cost at $4,076.4 million (i.e., about $4.1 billion).
Some in Congress and elsewhere are interested in the potential for accelerating the procurement
of LHA-9 from FY2024 to an earlier year, such as FY2020 or FY2021, in part to achieve better
production learning curve benefits in shifting from production of LHA-8 to LHA-9 and thereby
reduce LHA-9’s procurement cost in real (i.e., inflation-adjusted) terms. For example, the Senate
Armed Services Committee’s report (S.Rept. 115-262 of June 5, 2018) on the John S. McCain
National Defense Authorization Act for Fiscal Year 2019 (S. 2987) stated the following:
The committee remains concerned with the Navy procurement profile for large deck
amphibious assault ships, which includes a span of 7 years until the next large deck
amphibious assault ship (LHA–9) is procured in 2024.
The committee notes that efficiencies could be gained by reducing this span, which could
enable a steadier workforce with an increased learning curve, material and equipment
suppliers on more reliable and fixed delivery contracts, and a more effective continuous
improvement schedule.
The committee urges the Secretary of the Navy to accelerate procurement of LHA–9 to not
later than 2021…. (Pages 82-83)17
As part of its action on the Navy’s proposed FY2019 budget, Congress provided $350 million in
unrequested AP funding for LHA-9, in part to encourage the Navy to accelerate the procurement
of LHA-9 from FY2024 to an earlier fiscal year, such as FY2020 or FY2021.

Under the Navy’s FY2020 budget submission, the Navy continues to show LHA-9 as a ship
planned for procurement in FY2024, and the Navy’s proposed FY2020 budget does not request
any additional procurement or AP funding for the ship. Consistent with past practice for procuring
LHA/LHD-type amphibious ships, the Navy’s FY2020 budget submission anticipates using two-
year incremental funding (i.e., split funding) to procure LHA-9, with the bulk of the ship’s
procurement cost to be divided between FY2024 and FY2025. Table 3 shows FY2020-FY2024
funding for the ship under the Navy’s FY2020 budget submission.

Amphibious Warship Industrial Base
Huntington Ingalls Industries/Ingalls Shipbuilding (HII/Ingalls) of Pascagoula, MS, is the Navy’s
current builder of both LPDs and LHA/LHD-type ships, although other U.S. shipyards could also
build amphibious ships.18 The amphibious warship industrial base also includes many supplier
firms in numerous U.S. states that provide materials and components for Navy amphibious ships.
HII states that the supplier base for its LHA production line, for example, includes 457 companies
in 39 states.19
Issues for Congress
FY2020 Procurement and Funding Issues
FY2020 procurement and funding issues for Congress for FY2020 include the following:
 whether to procure LPD-31 in FY2020 or FY2021;
 whether to procure LPD-31 (if it is procured in FY2020) with full funding or
incremental funding;
 the amount of procurement or AP funding to provide for LPD-31 and LHA-9 in
FY2020; and

18 Amphibious ships could also be built by U.S. shipyards such as HII/Newport News Shipbuilding (HII/NNS) of
Newport News, VA; General Dynamics/National Steel and Shipbuilding Company (GD/NASSCO) of San Diego, CA;
and (for LPDs at least) General Dynamics/Bath Iron Works (GD/BIW) of Bath, ME. The Navy over the years has from
time to time conducted competitions among shipyards for contracts to build amphibious ships.

Navy LPD-17 Flight II and LHA Amphibious Ship Programs

 more generally whether the Navy is placing too much, too little, or about the
right amount of emphasis on amphibious ships in its FY2020 budget submission,
particularly compared to other Navy shipbuilding programs.
Regarding the first issue above, supporters of procuring LPD-31 in FY2020 could argue that it
could put the Navy on a path to achieving the 38-ship amphibious ship force-level goal sooner
than FY2026, permit the $350 million in AP funding that Congress provided for the program in
FY2019 to be executed as intended, and leave more budgetary room in FY2021 for funding other
Navy programs. Supporters of procuring LPD-31 in FY2021 could argue that FY2026 is an
acceptable date for achieving the 38-ship amphibious ship force-level objective, particularly
given the challenges the Navy faces for meeting some of its other force-level goals in coming
years (such as those for attack submarines and aircraft carriers); that in a situation of finite Navy
or Department of Defense (DOD) funding, procuring LPD-31 in FY2020 might require
reductions in funding for other Navy or DOD programs, with an uncertain net result on Navy or
DOD capabilities; and that Congress can make the FY2019 AP funding executable by passing
legislation permitting the funding to be used on an LPD-17 Flight II ship procured in FY2021.
Regarding the second issue above, supporters of procuring LPD-31 with full funding could argue
that it would leave more budgetary room in FY2021 and perhaps one or more years beyond that
for funding other Navy programs, and that Navy surface ships other than aircraft carriers and
LHA/LHD-type amphibious assault ships have generally been procured with full funding rather
than incremental funding. Supporters of funding LPD-31 with incremental funding could argue
that doing so would reduce FY2020 funding needs for LPD-31, preserving more FY2020 funding
for other Navy or DOD programs, and that there have been a few instances over the years in
which Navy surface ships other than aircraft carriers and LHA/LHD-type amphibious assault
ships have been procured with incremental funding.
Regarding the third issue above, factors that Congress may consider include whether the Navy
has properly scheduled and accurately estimated the work on these ships it is proposing to do in
FY2020, and how the type and amount of work to be done on these ships in FY2020 would
change if LPD-31 were procured in FY2020 instead of FY2021, and if procurement of LHA-9
were accelerated from FY2024 to an earlier fiscal year, such as FY2020 or FY2021.
Regarding the fourth issue above, supporters of amphibious ships might argue that by deferring
the procurement of LPD-31 to FY2021, reducing the number of LPD-17 Flight II ships to be
procured in FY2020-FY2024, and not accelerating the procurement of LHA-9 from FY2024 to an
earlier fiscal year, the Navy’s FY2020 budget submission is placing a reduced emphasis on
amphibious ships in its shipbuilding plans, particularly compared to other type of Navy ships,
such as attack submarines, destroyers, and frigates, all of which experienced additions or
accelerations in FY2020 or FY2021 under the Navy’s FY2020 budget submission.20 Amphibious
ships, they could argue, are as important as these other types of ships, and are in high demand by
U.S. regional combatant commanders. Other observers, while acknowledging the value of
amphibious ships, might argue that within a finite Navy budget, the Navy needs to make difficult
choices about what type of ships to procure; that attack submarines, destroyers, and frigates are
critical for countering China’s improving naval capabilities and for performing other missions;
and that the Navy currently has substantial shortfalls in attack submarines, large surface

combatants (such as destroyers), and small surface combatants (such as frigates) relative to its
force-level goals for those types of ships.
A Navy information paper on options for funding the procurement of LPD-31 (the second LPD-
17 Flight II ship) states the following:
QUESTION: Explain the end cost to build LPD 31 under the following conditions:
a. FY19 ($350M), FY20 ($247M), and FY21 funding are all available
b. FY19 ($350M) and FY21 funding are available (FY20 $247M is not available)
c. Only FY20 ($247M) and FY21 funding are available (FY19 $350M is not available)
RESPONSE:…
Scenarios:
Option (a) represents the most affordable scenario with no increase in end cost. This
scenario assumes access to FY19 Advance Procurement (AP) funds in the Summer 2019
to initiate LPD 31 LLTM procurements, which will mitigate inflation impacts. The funding
may also be used to leverage Government Furnished Equipment (GFE) quantity buys. This
most affordable scenario assumes incremental funding authority and the appropriation of
FY20 as Full Funding with the balance in FY21. That approach would enable the Navy to
put LPD 31 under contract in FY20 and start construction on the optimized 18-month
center. The authority to proceed to proposal, negotiations, and award earlier will maximize
the ability to leverage the recently awarded LPD 30 and mitigate the impacts associated
with a delayed contract negotiation and award timeline.
Option (b) represents the medium-cost scenario with a potential end cost increase of ~2%
relative to the PB19 profile. This scenario assumes access to FY19 AP funds in the Summer
2019 to initiate LPD 31 LLTM procurements and may also be used to leverage GFE
quantity buys. The construction contract would be awarded upon authorization and
appropriation of the FY21 ship. Although this scenario may allow the shipbuilder to start
LPD 31 construction on the optimized 18-month center and minimize loss of learning
relative to prior ships, it carries the potential for inflation impacts and increased overhead
rates. Additionally, the contractor may include increased risk in their LPD 31 pricing
depending on shipyard loading, future business projections, and lessons learned from ships
currently in production.
Option (c) represents the most costly scenario with a potential end cost increase of ~6%
relative to the PB19 profile. This scenario assumes that LPD 31 LLTM procurement would
not begin until the FY20 authorization and appropriations bills are enacted. The
construction contract would be awarded upon authorization and appropriation of the FY21
ship. Due to LLTM requirements, ship construction would start at least 6-9 months later
than the optimal 18-month centers (i.e. 24+ months after LPD 30). This scenario also
introduces the potential for additional inflation impacts, increased overhead rates, and loss
of learning.21
Potential Change in Required Number of Amphibious Ships
Another potential issue for Congress is whether the Navy’s next FSA will change the required
number of amphibious ships, and if so, whether and how that might change the required number
of LPD-17 Flight II ships. As discussed earlier, statements from the Commandant of the Marine
Corps suggest that the new FSA that is to be completed by the end of 2019 might change the

Navy’s amphibious ship force to an architecture based on a new amphibious lift target and a new
mix of amphibious ships.
Technical and Cost Risk in LPD-17 Flight II and LHA Programs
Another potential issue for Congress is technical and cost risk in the LPD-17 Flight II and LHA
programs.
Technical Risk
Regarding technical risk in the LPD-17 Flight II program, a May 2019 Government
Accountability Office (GAO) report—the 2019 edition of GAO’s annual report surveying DOD
major acquisition programs—states the following about the LPD-17 Flight II program:
Current Status
The Navy planned to accelerate purchase of LPD 30—the first fully configured Flight II
ship—after Congress appropriated $1.8 billion above the fiscal year 2018 budget request,
according to program officials. The Navy reported that it awarded contracts in August 2018
for LPD 30 long lead time materials and in March 2019 for lead ship construction.
The Navy based the Flight II design on Flight I, with modifications to reduce costs and
meet new requirements. According to program officials, roughly 200 design changes will
distinguish the two flights including replacing the composite mast with a steel stick.
Officials stated that the design would not rely on any new technologies. However, the Navy
plans to install a new radar, the Enterprise Air Surveillance Radar, which is still in
development. The Navy expects live radar system testing through November 2019, with a
complete radar prototype in February 2020. Although program officials consider these
activities to be low risk, the Navy will make its decision to begin ship construction by
December 2019 without incorporating lessons learned from radar testing into the design.
Starting construction before stabilizing the design could require the Navy to absorb costly
design changes and rework during ship construction.
The Navy initially pursued a limited competition for LX(R), but now has a non-competitive
acquisition strategy for LPD 17 Flight II. The Navy plans to award sole-source contracts
to Huntington Ingalls—the only shipbuilder of Flight I ships—for Flight II construction.
Further, the program did not request a separate independent cost estimate for Flight II prior
to awarding the LPD 30 detail design and construction contract. At the same time, the Navy
identified no plans to establish a cost baseline specific to Flight II. Without this baseline,
the Navy would report full LPD 17 program costs—rather than Flight II specific costs—
constraining visibility into Flight II.
Program Office Comments
We provided a draft of this assessment to the program office for review and comment. The
program office provided technical comments, which we incorporated as appropriate The
program office stated that LPD Flight II is included under the existing LPD 17 acquisition
program baseline, and that no other viable contractor responded to a public notice regarding
the Navy’s plan to award Huntington Ingalls the LPD 30 construction contract.22
Regarding technical risk in the LHA program, the May 2019 GAO report stated the following
about the LHA program:

Practices Continues to Undercut DOD’s Investments, GAO-19-336SP, May 2019, p. 134.

Navy LPD-17 Flight II and LHA Amphibious Ship Programs

In June 2017, the Navy exercised a contract option for detail design and construction of the
LHA 8. The LHA 8 incorporates significant design changes from earlier ships in the LHA
6 class, but Navy officials were unable to quantify the changes. The Navy started
construction in October 2018 and LHA 8 is scheduled to be delivered in January 2024.
The LHA 8 program office has not identified any critical technologies. However, the ship
is relying on technology that is currently being developed by another Navy program, the
Enterprise Air Surveillance Radar (EASR), with delivery expected in August 2021. EASR,
intended to provide self-defense and situational awareness capabilities, is derived from the
pre-existing Air and Missile Defense Radar program, but will be a different size and will
rotate. LHA 8 program officials have identified the radar as the program’s highest
development risk. If the radar is not delivered on schedule, Navy officials report that this
could lead to out-of-sequence design and delayed installation and testing. Officials
responsible for developing the radar, however, stated that the radar is approaching maturity
and is on schedule to be delivered to the shipbuilder when needed.
The Navy began construction with about 61 percent of the LHA 8 product model
completed—an approach inconsistent with shipbuilding best practices. These best practices
call for 100 percent completion of 3D product modeling prior to construction start to
minimize the likelihood of costly re-work and out of sequence work that can drive schedule
delays. The Navy, however, estimates that the LHA 8 shipbuilder will not complete 100
percent of the ship’s 3D product model until June 2019, almost 8 months after the start of
construction.
Program Office Comments
We provided a draft of this assessment to the program office for review and comment. The
program office provided technical comments, which we incorporated where appropriate.
The program office stated that the Navy understands all design changes incorporated on
the LHA 8, such as reintroducing the well deck and incorporating EASR. According to the
program office, the Navy does not begin construction on any section of the LHA 8 ship
before completing that respective section’s design.23
Cost Risk
Regarding cost risk in the LPD-17 Flight II program, an October 2019 Congressional Budget
Office (CBO) report on the cost of the Navy’s shipbuilding programs states the following:
The Navy estimates that the LPD-17 Flight IIs would cost $1.6 billion each, on average,
and that the lead ship would cost $1.7 billion to $1.8 billion.… To achieve its cost goal for
the LPD-17 Flight II, the Navy plans to further alter the LPD-17 design and, perhaps, to
change the way it buys them: The Flight II variant would have substantially less capability
than the LPD-17 class, and the Navy might use block-buy or multiyear authority to
purchase the ships, although it has not yet stated an intention to do so. Such authority would
commit the government to buying a group of ships over several years, thereby realizing
savings as a result of the predictable and steady work provided to the construction shipyard
and to the vendors that provide parts and components to the shipbuilder. The authority
would be similar to that provided for the Arleigh Burke class destroyers, Virginia class
attack submarines, and LCSs [Littoral Combat Ships].
CBO estimates that the LPD-17 Flight II class would cost an average of $1.9 billion per
ship. The agency [CBO] used the existing LPD-17 hull as the starting point for its estimate
and then adjusted the ship’s size to reflect the reduced capability it expects for the Flight

II. CBO’s estimate reflects the assumption that the Navy would ultimately use multiyear
or block-buy procurement authority to purchase the ships.24
Regarding cost risk in the LHA program, the October 2019 CBO report states the following:
The Navy estimates that the LHA-6 class amphibious assault ships would cost $3.4 billion
each …. Under the 2020 plan, a seven-year gap separates the last LHA-6 class ship ordered
in 2017 and the next one, slated to be purchased in 2024, which in CBO’s estimation would
effectively eliminate any manufacturing learning gleaned from building the first 3 ships of
the class. As a result, CBO’s estimate is higher than the Navy’s, at $3.9 billion per ship.25

H.Rept. 116-120 also states the following:
Amphibious Forces Modernization
While the Secretary of the Navy has been taking certain steps to modernize forces to
operate in a contested environment, the committee believes that the Department of the
Navy needs to aggressively assess and optimize future forces.
Therefore, the committee directs the Secretary of the Navy to submit a brief to the House
Committee on Armed Services by February 1, 2020 as to options to improve procurement
protocols with legacy and future forces force structure requirements. Such briefing shall
include each of the following: amphibious warfare concepts and requirements as they relate
to shipbuilding and modernization; options to garner efficiencies into amphibious ship
acquisition; an assessment to optimize the current and projected aviation and surface
connectors strategy; options to expand aviation projection from amphibious vessels;
options to expand command and control networks; options to incorporate vertical launch
systems; and a fiscal assessment of these options. (Page 16)
Senate
The Senate Armed Services Committee, in its report (S.Rept. 116-48 of June 11, 2019) on S.
1790, recommended the funding levels shown in the SASC column of Table 4. Regarding these
recommended funding levels, S.Rept. 116-48 states the following:
LPD-class amphibious transport ship
The budget request included no funding in line number 12 of Shipbuilding and Conversion,
Navy (SCN), for procurement of LPD Flight II-class amphibious transport ships.
The committee notes that the Navy has identified LPD-30, which was authorized and
appropriated in fiscal year 2018, as the first Flight II LPD. In the fiscal year 2019 budget
request, the Navy planned to procure the next Flight II LPD, LPD-31, in fiscal year 2020.
The committee is concerned that the fiscal year 2020 budget request’s delay of procurement
of LPD-31 to fiscal year 2021 could result in production inefficiency, increased cost, and
delay in reaching the Navy’s requirement for 38 amphibious ships.
Therefore, the committee recommends an increase of $525.0 million in line number 12 of
SCN for incremental funding of the amphibious transport ship designated LPD-31.

Navy LPD-17 Flight II and LHA Amphibious Ship Programs

The committee’s intent is for the Navy to use the $350.0 million appropriated in SCN line
number 13 in fiscal year 2019 and additional fiscal year 2020 funds in SCN line number
12 to procure LPD-31 long-lead material and start construction as efficiently as possible.
Consistent with the budget request, the committee expects the Navy to request the balance
of costs for LPD-31 in fiscal year 2021.
LPD-class amphibious transport ship advance procurement
The budget request included $247.1 million in line number 13 of Shipbuilding and
Conversion, Navy (SCN), for advance procurement of LPD Flight II-class amphibious
transport ships.
The committee recommends transferring the funds requested in line number 13 of SCN to
line number 12 of SCN to support incremental funding of the amphibious transport ship
designated LPD-31.
Therefore, the committee recommends a decrease of $247.1 million in line number 13 of
SCN for advance procurement of LPD Flight II-class amphibious transport ships.
LHA replacement amphibious assault ship
The budget request included no funding in line number 15 of Shipbuilding and Conversion,
Navy (SCN), for procurement of LHA replacement amphibious assault ships.
The committee remains concerned with the Navy procurement profile for large deck
amphibious assault ships, which includes a span of 7 years until the next large deck
amphibious assault ship (LHA-9) would be procured in fiscal year 2024.
The committee notes that efficiencies could be gained by reducing this span, including
steadier workflow with an increased learning curve, material and equipment suppliers with
more predictable delivery contracts, and a more effective continuous improvement
schedule.
The committee urges the Secretary of the Navy to accelerate procurement of LHA-9,
including putting the $356.0 million appropriated in fiscal year 2019 for this ship on
contract to procure long lead-time material as soon as possible and leveraging the
incremental funding authority provided elsewhere in this Act to start construction and build
LHA-9 as efficiently as possible.
Therefore, the committee recommends an increase of $650.0 million in line number 15 of
SCN. (Pages 23-24)
Section 122 of S. 1790 as reported by the committee states the following:
SEC. 122. Capabilities based assessment for naval vessels that carry fixed-wing
aircraft.
(a) In general.—Not later than 30 days after the date of the enactment of this Act, the
Secretary of the Navy shall initiate a capabilities based assessment to begin the process of
identifying requirements for the naval vessels that will carry fixed-wing aircraft following
the ships designated CVN–81 and LHA–9.
(b) Elements.—The assessment shall—
(1) conform with the Joint Capabilities Integration and Development System, including
Chairman of the Joint Chiefs of Staff Instruction 5123.01H; and
(2) consider options for the vessels described under subsection (a) that would enable greater
commonality and interoperability of naval aircraft embarked on such naval vessels,
including aircraft arresting gear and launch catapults.
(c) Notification requirement.—Not later than 15 days after initiating the assessment
required under subsection (a), the Secretary of the Navy shall notify the congressional
Congressional Research Service

Navy LPD-17 Flight II and LHA Amphibious Ship Programs

defense committees of such action and the associated schedule for completing the
assessment and generating an Initial Capabilities Document.
Regarding Section 122, S.Rept. 116-48 states the following:
Capabilities based assessment for naval vessels that carry fixed-wing aircraft (sec.
122)
The committee recommends a provision that would require the Secretary of the Navy to
conduct a capabilities-based assessment to clarify the future requirements for naval vessels
that carry fixed-wing aircraft.
The committee notes that the budget request’s proposal to retire the USS Harry S. Truman
(CVN-75) early would yield a force with 10 or fewer aircraft carriers for more than 20
years. The budget request also includes a 7-year gap until the funding of the next
amphibious assault ship, LHA-9, which will likely result in a production break. The
committee is concerned that both the CVN-75 and LHA-9 proposals are contrary to current
Navy force structure requirements and will result in significant negative impacts for the
shipbuilding industrial base.
The committee also notes that the Under Secretary of the Navy stated in February 2019,
“If $13 billion is unaffordable ... what’s the next carrier look like? Is it going to be as
advanced as [the USS Gerald R. Ford] or is it going to be smaller? ... We don't know the
answers to that, but we're looking at those.”
The committee also notes that all three future fleet platform architecture studies required
by section 1067 of the National Defense Authorization Act for Fiscal Year 2016 (P.L. 114-
92) recommended that the Navy pursue a class of aircraft carriers smaller than the Ford-
class. The committee believes that smaller aircraft carriers could both increase aircraft
carrier capacity and provide a more efficient means to conduct a range of missions with
lower sortie requirements, including support for amphibious operations.
Accordingly, the committee directs the Secretary of the Navy to consult the fleet
architecture studies, as well as the report on alternative aircraft carrier options required by
section 128 of the National Defense Authorization Act for Fiscal Year 2016 (P.L. 114-92),
and initiate a capabilities-based assessment to begin the process of identifying requirements
for the naval vessels that will carry fixed-wing aircraft following CVN-81 and LHA-9.

Section 124 of S. 1790 as reported by the committee states the following:
SEC. 124. Design and construction of amphibious transport dock designated LPD–
31.
(a) In general.—The Secretary of the Navy may enter into a contract for the design and
construction of the amphibious transport dock designated LPD–31 using amounts
authorized to be appropriated for the Department of Defense for Shipbuilding and
Conversion, Navy.
(b) Use of incremental funding.—With respect to the contract entered into under subsection
(a), the Secretary may use incremental funding to make payments under the contract with
amounts authorized to be appropriated in fiscal years 2019, 2020, and 2021.
(c) Condition for out-year contract payments.—The contract entered into under subsection
(a) shall provide that any obligation of the United States to make a payment under such
contract for any fiscal year after fiscal year 2020 is subject to the availability of
appropriations for that purpose for such fiscal year.
Regarding Section 124, S.Rept. 116-48 states the following:
Design and construction of amphibious transport dock designated LPD-31 (sec. 124)

19

Navy LPD-17 Flight II and LHA Amphibious Ship Programs

The committee recommends a provision that would authorize the Secretary of the Navy to
enter into and incrementally fund a contract for design and construction of the amphibious
transport dock designated LPD-31.
The committee notes that in testimony before the Senate Armed Services Committee on
April 7, 2019, the Secretary of the Navy and Chief of Naval Operations supported
incremental funding authority for LPD-31. (Page 9)
Section 125 of S. 1790 as reported by the committee states the following:
SEC. 125. LHA Replacement Amphibious Assault Ship Program.
(a) Authority to use incremental funding.—The Secretary of the Navy may enter into and
incrementally fund a contract for detail design and construction of the LHA replacement
ship designated LHA 9 and, subject to subsection (b), funds for payments under the
contract may be provided from amounts authorized to be appropriated for the Department
of Defense for Shipbuilding and Conversion, Navy, for fiscal years 2019 through 2025.
(b) Condition for out-year contract payments.—A contract entered into under subsection
(a) shall provide that any obligation of the United States to make a payment under the
contract for any subsequent fiscal year is subject to the availability of appropriations for
that purpose for such subsequent fiscal year.
(c) Repeal of obsolete authority.—Section 125 of the John Warner National Defense
Authorization Act for Fiscal Year 2007 (Public Law 109–364; 120 Stat. 2106) is repealed.
Regarding Section 125, S.Rept. 116-48 states the following:
LHA Replacement Amphibious Assault Ship Program (sec. 125)
The committee recommends a provision that would authorize the Secretary of the Navy to
enter into and incrementally fund a contract for design and construction of the LHA
replacement ship designated LHA-9.
The committee notes that in testimony before the Senate Armed Services Committee on
April 7, 2019, the Secretary of the Navy and Chief of Naval Operations supported
incremental funding authority for LHA-9.
The provision would also repeal section 125 of the John Warner National Defense
Authorization Act for Fiscal Year 2007 (P.L. 109-364). (Page 9)
S.Rept. 116-48 also states the following:
Acquisition strategy for LHA-9 and LHA-10
The committee notes that the Navy estimates that $4.0 billion will be saved using a block
buy acquisition strategy for the procurement of CVN-80 and CVN-81.
The committee believes that such an approach for LHA-9 and LHA-10 could provide
substantial cost savings as well as needed stability and predictability for the shipbuilder
and its vendor base.
Accordingly, not later than October 1, 2019, the committee directs the Secretary of the
Navy to submit a report to the congressional defense committees on the merits of pursuing
a block buy acquisition strategy for LHA-9 and LHA-10.
This report shall include a business case analysis comparing the cost and schedule of single
ship contracts for LHA-9 and LHA-10 with a block buy contract for such ships as well as
a description of other key considerations that the Secretary deems appropriate.
If the business case analysis shows that pursuing a block buy strategy for LHA-9 and LHA-
10 has merit, the committee strongly encourages the Secretary to consider inclusion of such
a proposal in the Navy’s budget request for fiscal year 2021.

Acquisition strategy for LPD Flight II-class ships
The committee notes that the Navy estimates that $4.0 billion will be saved using a block
buy acquisition strategy for the procurement of CVN-80 and CVN-81.
The committee believes that a block buy or multiyear procurement approach for LPD Flight
II-class amphibious transport ships could provide substantial cost savings as well as needed
stability and predictability for the shipbuilder and its vendor base.
Accordingly, not later than October 1, 2019, the committee directs the Secretary of the
Navy to submit a report to the congressional defense committees on the merits of pursuing
a block buy or multiyear procurement acquisition strategy for LPD Flight II-class ships.
This report shall include a business case analysis comparing the cost and schedule of single

31. Additionally, the Secretary would be authorized to use incremental funding authority
to complete the construction.
The Senate bill contained a similar provision (sec. 124).
The Senate recedes.
The conferees’ intent is for the Secretary of the Navy to use the $350.0 million appropriated
in Shipbuilding and Conversion, Navy (SCN) line number 13 in fiscal year 2019 and
additional fiscal year 2020 funds in SCN line number 12 to procure LPD–31 long-lead
material and start construction as efficiently as possible. Consistent with the budget
request, the conferees expect the Navy to request the balance of costs for LPD–31 in fiscal
year 2021.
FY2020 DOD Appropriations Act (H.R. 2968/S. 2474)
House
The House Appropriations Committee, in its report (H.Rept. 116-84 of May 23, 2019) on H.R.
2968, recommended the funding levels shown in the HAC column of Table 4. The recommended
reduction of $247.1 million in LPD-17 Flight II advance procurement funding (the entire
requested amount) is for “Advance procurement [that was] funded in fiscal year 2019.” (Page
175)
Senate
The Senate Appropriations Committee, in its report (S.Rept. 116-103 of September 12, 2019) on
S. 2474, recommended the funding levels shown in the SAC column of Table 4.
In S. 2474 as reported by the committee, the paragraph that makes appropriations for the
Shipbuilding and Conversion, Navy (SCN) appropriation account includes this provision:
… Provided further, That an appropriation made under the heading “Shipbuilding and
Conversion, Navy” provided for the purpose of “Program increase—advance procurement
for fiscal year 2020 LPD Flight II and/or multiyear procurement economic order quantity”
shall be considered to be for the purpose of “Program increase—advance procurement of
LPD 31”.
S.Rept. 116-103 states:
LPD Flight II.—The fiscal year 2020 President’s budget request includes $247,100,000 for
advance procurement [AP] of LPD 31. The Committee notes that $350,000,000 was
appropriated in AP for this ship in fiscal year 2019, but the Navy delayed the procurement
of LPD 31 and has not obligated or expended these funds. Therefore, the Committee
recommends adjusting previously appropriated AP in accordance with the Navy’s
requirements and recommends $747,100,000 for LPD 31 in fiscal year 2020. (Page 122)
