Navy Medium Landing Ship (LSM) (Previously
April 13, 2023
Light Amphibious Warship [LAW]) Program:
Ronald O'Rourke
Background and Issues for Congress
Specialist in Naval Affairs

The Navy’s Medium Landing Ship (LSM) program, previously called the Light Amphibious
Warship (LAW) program, envisions procuring a class of 18 to 35 new amphibious ships to

support the Marine Corps, particularly in implementing a new Marine Corps operational concept
called Expeditionary Advanced Base Operations (EABO). The Navy wants to procure the first LSM in FY2025. The Navy’s
proposed FY2024 budget requests $14.7 million in research and development funding for the program.
The EABO concept was developed with an eye toward potential conflict scenarios with China in the Western Pacific. Under
the concept, the Marine Corps envisions, among other things, having reinforced-platoon-sized Marine Corps units maneuver
around the theater, moving from island to island, to fire anti-ship cruise missiles (ASCMs) and perform other missions so as
to contribute, alongside Navy and other U.S. military forces, to U.S. operations to counter and deny sea control to Chinese
forces. The LSMs would be instrumental to these operations, with LSMs embarking, transporting, landing, and subsequently
reembarking these small Marine Corps units.
LSMs would be much smaller and individually much less expensive to procure and operate than the Navy’s current
amphibious ships. Under the Navy’s FY2024 budget submission, the first LSM would be procured in FY2025 at a cost of
$187.9 million, the second LSM would be procured in FY2026 at a cost of $149.2 million, the third and fourth LSMs would
be procured in FY2027 at a combined cost of $297.0 million (i.e., an average cost of about $148.5 million each), and the fifth
and sixth LSMs in FY2028 at a combined cost of $296.2 million (i.e., an average of about $148.1 million each). The first
LSM would cost more than subsequent ships in the program because the procurement cost of the first LSM would include
much or all of the detailed design/nonrecurring engineering (DD/NRE) costs for the class. (It is a traditional Navy budgeting
practice to include much of all of the DD/NRE costs for a class of ship in the procurement cost of the lead ship in the class.)
The LSM as outlined by the Navy could be built by any of several U.S. shipyards. The Navy’s baseline preference is to have
a single shipyard build all the ships, but the Navy is open to having them built in multiple yards to the same design if doing
so could permit the program to be implemented more quickly and/or less expensively. The Navy’s FY2024 budget
submission states that the contract for the construction of the first LSM would be awarded in December 2024, and that the
ship would be delivered in July 2028.
The LSM program poses a number of potential oversight matters for Congress. The issue for Congress is whether to approve,
reject, or modify the Navy’s annual funding requests and envisioned acquisition strategy for the program. Congress’s
decisions regarding the program could affect Navy and Marine Corps capabilities and funding requirements and the U.S.
shipbuilding industrial base.

Navy Medium Landing Ship (LSM) Program

Introduction
This report provides background information and issues for Congress on the Navy’s Medium
Landing Ship (LSM) program, previously called the Light Amphibious Warship (LAW) program.
The LSM program envisions procuring a class of 18 to 35 new amphibious ships to support the
Marine Corps, particularly in implementing a new Marine Corps operational concept called
Expeditionary Advanced Base Operations (EABO). The Navy wants to procure the first LSM in
FY2025. The Navy’s proposed FY2024 budget requests $14.7 million in research and
development funding for the program.
The LSM program poses a number of potential oversight matters for Congress. The issue for
Congress is whether to approve, reject, or modify the Navy’s annual funding requests and
envisioned acquisition strategy for the program. Congress’s decisions regarding the program
could affect Navy and Marine Corps capabilities and funding requirements and the U.S.
shipbuilding industrial base.
A separate CRS report discusses the Navy’s programs for building much-larger LPD-17 Flight II
and LHA-class amphibious ships.1 Other CRS reports provide an overview of Navy force
structure and shipbuilding plans2 and the Marine Corps’ overall plan for redesigning its units and
equipment to meet future mission demands, called Force Design 2030, of which the LSM
program is a part.3
Background
U.S. Navy Amphibious Ships
Roles and Missions
Navy amphibious ships are operated by the Navy, with crews consisting of Navy personnel. They
are battle force ships, meaning ships that count toward the quoted size of the Navy. The primary
function of Navy amphibious ships is to lift (i.e., transport) embarked U.S. Marines and their
weapons, equipment, and supplies to distant operating areas, and enable Marines to conduct
expeditionary operations ashore in those areas. Although amphibious ships can be used 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,4 amphibious ships are potentially useful for a range
of combat and noncombat operations.5
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 in multiship formations called amphibious
groups (ARGs). Amphibious ships are also sometimes forward-deployed on an individual basis,
particularly for conducting peacetime engagement activities with foreign countries or for
responding to smaller-scale or noncombat contingencies.
Current Types of Amphibious Ships
The Navy’s current amphibious-ship force consists entirely of large amphibious ships, including
the so-called “big-deck” amphibious assault ships, designated LHA and LHD, which look like
medium-sized aircraft carriers, and the smaller (but still quite sizeable) amphibious ships,
designated LPD or LSD, which are sometimes called “small-deck” amphibious ships.6 As
mentioned earlier, a separate CRS report discusses the Navy’s current programs for procuring
new LHA- and LPD-type ships.7 The LSMs discussed in this CRS report would be much smaller
than the Navy’s current amphibious ships.
Amphibious Ship Force-Level Goal Under 355-Ship Plan of 2016
The Navy’s current force-level goal, released in December 2016, calls for achieving and
maintaining a 355-ship fleet that includes 38 larger amphibious ships—12 LHA/LHD-type ships,
13 LPD-17 Flight I class ships, and 13 LPD-17 Flight II class ships (12+13+13).8 This 38-ship
force-level goal predates the LSM program and consequently includes no LSMs.

4 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 in many cases 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.)
5 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.
6 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 4. The terms “large-deck” and “small-deck” refer to the size of the ship’s flight deck.

Navy Medium Landing Ship (LSM) Program

Amphibious Ship Force at End of FY2022 and Projected for End of FY2024
The Navy’s force of amphibious ships at the end of FY2022 included 31 larger ships, including 9
amphibious assault ships (2 LHAs and 7 LHDs), 12 LPD-17 Flight I class ships, and 10 older
LSD-41/49 class ships. The Navy’s FY2024 budget submission projects that the Navy at the end
of FY2024 will include 29 larger amphibious ships, including 9 LHA/LHD-type ships, 13 LPD
Flight I class ships, and 7 LSD-41/49 class ships.
Emerging New Amphibious Ship Force-Level Goal
The Navy and OSD have been working since 2019 to develop a new force-level goal to replace
the Navy’s 355-ship force-level goal, but have not been able to come to closure on a successor
goal. Required numbers of amphibious ships are reportedly a major issue in the ongoing
discussion. The Navy’s FY2023 30-year (FY2023-FY2052) shipbuilding plan, released on April
20, 2022, includes a table summarizing the results of studies that have been conducted on the
successor force-level goal. These studies outline potential future fleets with 6 to 10 LHAs/LHDs
and 30 to 54 other amphibious ships, including but not necessarily limited to LPDs and LSMs.9
Marine Corps officials state that, from their perspective, a minimum of 66 larger and smaller
amphibious ships will be required in coming years, including a minimum of 31 larger amphibious
ships (10 LHAs/LHDs and 21 LPD-17s) plus 35 LSMs (aka “31+35”).10 Marine Corps officials
have stated that a force with fewer than 31 larger amphibious ships would increase operational
risks in meeting demands from U.S. regional combatant commanders for forward-deployed
amphibious ships and for responding to contingencies.11
At an April 26, 2022, hearing on Department of the Navy (DON) investment programs before the
Seapower subcommittee of the Senate Armed Services Committee, the Department of the Navy
testified that
In order to ensure the future naval expeditionary force is maximized for effective combat
power, while reflecting and supporting the force structure changes addressed in USMC’s
Force Design, the Secretary of the Navy directed an amphibious requirement study that
will inform refinement of amphibious ship procurement plans and shipbuilding profiles, as
well as inform the ongoing overall Naval Force Structure Assessment.12

Navy Medium Landing Ship (LSM) Program

In January 2022, Navy officials reportedly anticipated that the above-mentioned study would be
completed by the end of March 2022.13 At the end of March 2022, the study reportedly was
expected to be completed shortly.14 At the beginning of April 2022, the study reportedly was in its
final stages.15
The Navy’s FY2023 30-year (FY2023-FY2052) shipbuilding plan, released on April 20 2022,
states that “the Navy will begin assessment of a next-generation amphibious ship (i.e., LPD(X))
in FY2023.”16
A January 20, 2023, press report states:
The long-awaited Navy study to determine the future makeup of the U.S. amphibious
warship fleet has finally made it to Congress, but don’t hold your breath for the results:
they’re classified.
The Navy sent the Amphibious Force Requirements Study to the Congressional defense
committees on Dec. 28, Lt. Gabrielle Dimaapi, a spokeswoman for the Navy secretary,
said in an email statement Friday to Defense One.
The study was “closely coordinated with the Office of the Secretary of Defense Cost
Analysis and Program Evaluation and Office of Management and Budget prior to providing
it to Congress,” Dimaapi said. It “assessed the risk associated with the size and composition
of the future amphibious warship fleet. It focused on both traditional and planned
amphibious warships and platforms.”
Though the service “is not planning to release an unclassified summary of the report,” the
results “will be incorporated into an ongoing battle force ship assessment that will be
published later this year,” she said.
But it’s unclear how much of the amphibious ship study results will be revealed in the
battle force ship assessment. Last year’s assessment was also classified, and only the top-
level number of 373 ships was released, U.S. Naval Institute News reported.
Navy Secretary Carlos Del Toro has been promising for months that the amphibious ship
study would be ready in a matter of weeks, even testifying to that during a May Senate
Armed Services Committee hearing. When no study materialized, Sens. Tim Kaine, D-Va.,
and Roger Wicker, R-Miss., sent a letter in November to Del Toro asking for the study. In
early December, the secretary told reporters the document was almost ready, but was still
“being briefed to senior leadership.”17
FY2023 NDAA Provisions Regarding Amphibious Ship Force-Level Goal
The FY2023 National Defense Authorization Act (NDAA) (H.R. 7776/P.L. 117-263 of December
23, 2022) included the following provisions relating to the amphibious ship force-level goal:

Navy Medium Landing Ship (LSM) Program

 Section 1022 amended 10 U.S.C. 8026 to require the Secretary of the Navy to
ensure that the views of the Commandant of the Marine Corps are given
appropriate consideration before a major decision is made by an element of the
Department of the Navy outside the Marine Corps on a matter that directly
concerns amphibious force structure and capability.
 Section 1023, as noted earlier, amends 10 U.S.C. 8062 to require the Navy to
include not less than 31 operational larger amphibious ships, including 10
LHA/LHD-type ships and 21 LPD or LSD type ships.
 Section 1025 amends 10 U.S.C. 8695 to state that, in preparing a periodic battle
force ship assessment and requirement, the Commandant of the Marine Corps
shall be specifically responsible for developing the requirements relating to
amphibious warfare ships.
Medium Landing Ship (LSM) Program
Overview
As noted earlier, the LSM program may include 18 to 35 ships. A total of 18 is mentioned in a
July 2022 Navy document, Chief of Operations Navigation Plan 2022.18 A total of 35 is
mentioned regularly by Marine Corps officials, and would include nine operational LSMs for
each of three envisioned Marine Littoral Regiments (MLRs),19 plus eight additional LSMs to
account for factors such as a certain number of LSMs being in maintenance at any given
moment.20 LSMs would be much smaller and individually much less expensive to procure and
operate than the Navy’s current amphibious ships.
Procurement Schedule
The Navy wants to procure the first LSM in FY2025, the second in FY2026, the third and fourth
in FY2027, and the fifth and sixth LSMs in FY2028. The Navy’s FY2024 budget submission
states that the contract for the construction of the first LSM would be awarded in March 2025,
and that construction of the first LSM would begin in May 2026.
Procurement Cost
Under the Navy’s FY2024 budget submission, the first LSM would be procured in FY2025 at a
cost of $187.9 million, the second LSM would be procured in FY2026 at a cost of $149.2 million,
the third and fourth LSMs would be procured in FY2027 at a combined cost of $297.0 million
(i.e., an average cost of about $148.5 million each), and the fifth and sixth LSMs in FY2028 at a
combined cost of $296.2 million (i.e., an average of about $148.1 million each). The first LSM
would cost more than subsequent ships in the program because the procurement cost of the first
LSM would include much or all of the detailed design/nonrecurring engineering (DD/NRE) costs
for the class. (It is a traditional Navy budgeting practice to include much of all of the DD/NRE
costs for a class of ship in the procurement cost of the lead ship in the class.)

Navy Medium Landing Ship (LSM) Program

By way of comparison, the Navy’s most recently procured LHA-type amphibious ship has an
estimated unit procurement cost in the Navy’s FY2024 budget submission of about $3.8 billion,
and LPD-17 Flight II amphibious ships have unit procurement costs of about $1.9 billion.
Operational Rationale, Including EABO
To improve their ability to perform various missions in coming years, including a potential
mission of countering Chinese forces in a possible conflict in the Western Pacific, the Navy and
Marine Corps want to implement a new operational concept called Distributed Maritime
Operations (DMO).21 DMO calls for U.S. naval forces (meaning the Navy and Marine Corps)22 to
operate at sea in a less concentrated, more distributed manner, so as to complicate an adversary’s
task of detecting, identifying, tracking, and targeting U.S. naval forces, while still being able to
bring lethal force to bear against adversary forces.
In parallel with DMO, and with an eye toward potential conflict scenarios in the Western Pacific
against Chinese forces, the Marine Corps has developed two supporting operational concepts,
called Littoral Operations in a Contested Environment (LOCE) and Expeditionary Advanced
Base Operations (EABO). Under the EABO concept, the Marine Corps envisions, among other
things, having reinforced-platoon-sized Marine Corps units maneuver around the theater, moving
from island to island, to fire anti-ship cruise missiles (ASCMs) and perform other missions so as
to contribute, alongside Navy and other U.S. military forces, to U.S. operations to counter and
deny sea control to Chinese forces.
More specifically, the Marine Corps states that the EABO concept includes, among other things,
establishing and operating “multiple platoon-reinforced-size expeditionary advance base sites that
can host and enable a variety of missions such as long-range anti-ship fires, forward arming and
refueling of aircraft, intelligence, surveillance, and reconnaissance of key maritime terrain, and
air-defense and early warning,”23 The use of Marine Corps units to contribute to U.S. sea-denial
operations against an opposing navy by shooting ASCMs would represent a new mission for the
Marine Corps.24

U.S. Navy Capabilities—Background and Issues for Congress, by Ronald O'Rourke.
22 Although the term naval is often used to refer specifically to the Navy, it more properly refers to both the Navy and
Marine Corps, because both the Navy and Marine Corps are naval services. Even though the Marine Corps sometimes
operates for extended periods as a land fighting force (as it has done in recent years, for example, in Afghanistan and
Iraq), and is often thought of as the country’s second land army, it nevertheless is, by law, a naval service. 10 U.S.C.
§8001(a)(3) states, “The term ‘member of the naval service’ means a person appointed or enlisted in, or inducted or
conscripted into, the Navy or the Marine Corps.” DON officials sometimes refer to the two services as the Navy-
Marine Corps team. For additional discussion, see CRS In Focus IF10484, Defense Primer: Department of the Navy,

LSMs would be instrumental to these operations, with LSMs embarking, transporting, landing,
and subsequently reembarking these small Marine Corps units. An August 27, 2020, press report
states, “Maj. Gen. Tracy King, the director of expeditionary warfare on the chief of naval
operations’ staff (OPNAV N95), said today that LAW was perhaps the most important investment
the Marine Corps was making to optimize itself for expeditionary advance base operations
(EABO).”25 A February 2021 Marine Corps tentative manual on EABO states
Littoral maneuver will rely heavily on surface platforms such as the light amphibious
warship (LAW) and a range of surface connectors, as well as aviation assets. The LAW is
envisioned as the principal littoral maneuver vessel of the littoral force.…
The LAW supports the day-to-day maneuver of stand-in forces operating in the LOA
[littoral operations area]. It complements L-class amphibious ships26 and other surface
connectors. Utilizing the LAW to transport forces of the surface reduces the impacts of
tactical vehicles on the road network, increases deception, and allows for the sustainment
of forces during embarkation. The range, endurance, and austere access of LAWs enable
the littoral force to deliver personnel, equipment, and sustainment across a widely
distributed area. Shallow draft and beaching capability are keys to providing the volume
and agility to maneuver the required capabilities to key maritime terrain.
LAW employment requires reconnaissance and prior planning relating to the bathymetry
of the littoral environment. Effective LAW employment relies on knowledge of the beach
makeup, slope, currents, tidal effects, and other environment factors.
As envisioned and when properly postured, LAWs possess the range, endurance, speed,
sea-keeping, and C4ISR capabilities to support and conduct complementary operations
with, but not as part of, US Navy tactical groups, including an expeditionary strike group
(ESG) or amphibious ready group (ARG). Forward-positioned LAWs may augment the
capabilities of deploying ARG/MEUs during regional engagement and response to crises
or contingencies.
The LAW with embarked forces, generates and/or enables the following effects:

Rapidly maneuver forces from shore-to-shore in a contested environment

Sustain a combat-credible force ashore

Conduct enduring operations

Enable persistent joint-force operations and power projection

Provide increased and capable forward presence27
The survivability of the LSMs would come from their ability to hide among islands and other sea
traffic, from defensive support they would receive from other U.S. Navy forces, and from the
ability of their associated Marine Corps units to fire missiles at Chinese ships and aircraft that

could attack them with their own missiles (which can be viewed as an application of the notion
that the best defense is a good offense).
As a key platform for implementing EABO, the LSM program forms a part of Force Design
2030, the Marine Corps’ overall plan for plan for redesigning its units and equipment to meet
future mission demands.28
Ship Design
Design Features as Initially Conceived in 202029
As initially conceived in 2020, the Navy wanted LSMs to be a relatively simple and relatively
inexpensive ships with the following features, among others:
 a length of 200 feet to 400 feet;30
 a maximum draft of 12 feet;
 a displacement of up to 4,000 tons;31
 a ship’s crew of no more than 40 Navy sailors;32
 an ability to embark at least 75 Marines;
 4,000 to 8,000 square feet of cargo area for the Marines’ weapons, equipment,
and supplies;33
 a stern or bow landing ramp for moving the Marines and their weapons,
equipment, and supplies the ship to shore (and vice versa) across a beach;
 a modest suite of C4I equipment;34

 a 25mm or 30mm gun system and .50 caliber machine guns for self-defense;
 a transit speed of at least 14 knots, and preferably 15 knots;35
 a minimum unrefueled transit range of 3,500 nautical miles;36
 a “Tier 2+” plus level of survivability (i.e., ruggedness for withstanding battle
damage)—a level, broadly comparable to that of a smaller U.S. Navy surface
combatant (i.e., a corvette or frigate), that would permit the ship to absorb a hit
from an enemy weapon and keep the crew safe until they and their equipment
and supplies can be transferred to another LSM;37
 an ability to operate within fleet groups or deploy independently; and
 a 20-year expected service life.38
In addition to the above points, the Navy stated that the LSM’s design could be based on a
commercial-ship design.
A ship fitting the requirements listed above would be only a fraction as large as the Navy’s
current amphibious ships. The Navy’s LHA/LHD-type ships are 844 to 855 feet long and have a
full load displacements between 40,000 and 45,000 tons, while its and LPD-17 class ships are 684
feet long and have a full load displacement of 24,900 tons. As noted in the third bullet point
above, the LSM is to have a displacement of up to 4,000 tons—about 1/10th or 1/11th the
displacement of an LHA/LHD-type ship, and about 1/6th the displacement of an LPD-17 class
ships.
The above-listed maximum draft of 12 feet is intended to permit the ship to transit shallow waters
on its way to and from landing beaches. The Navy’s preference was that the ship’s cargo space be
in the form of open deck storage. Unlike most of the Navy’s current amphibious ships, the LSM
would not have a well deck.39 The above-listed transit speed of about 15 knots would be less than
the approximate 22-knot maximum sustained speed of larger U.S. Navy amphibious ships, but
would be a relatively fuel-efficient speed for moving ships through water,40 which would permit

39 As noted in footnote 4, a well deck is a large, covered, 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.

the ship to be equipped with a less powerful and consequently less expensive propulsion plant.
The above-listed 20-year expected service life is less than the 30- to 45-year expected service
lives of larger U.S. Navy amphibious ships—a difference that could reduce the LSM’s
construction cost for a ship of its type and size—and closer to the 25-year expected service life of
the Navy’s Littoral Combat Ships (LCSs).41
Subsequent Navy-Marine Corps Discussion on LSM Design Features
The Navy and Marine Corps reportedly have been discussing and debating some of LSM’s design
features, with a key issue being the amount of combat survivability to be incorporated into the
LSM’s design, and the impact this would have on the LSM’s unit procurement cost.
A September 14, 2022, press report stated
The Marine Corps and Navy remain at an impasse over the future of the Light Amphibious
Warship, as skepticism about the program’s viability mounts due to the internal division,
sources familiar with the program have told USNI News....
The division between the two services largely comes down to survivability, or what types
of weapons and armors to place on a ship that would operate in the first island chain,42
within range of Chinese missiles.
Adding more weapons and armor to LAW makes the ship more expensive. Projections in
2020 called for each LAW to cost $100 million, a number described as unrealistic by the
person familiar with program discussions. Now the Marine Corps wants the ship to cost
around $150 million apiece so it can buy more of them, while the Navy is pushing for a
more survivable ship that would end up costing about $300 million each.43
An October 5, 2022, press report states
The U.S. Navy and Marine Corps, facing a decision point early next year on the light
amphibious warship, are working to balance the Corps’ focus on affordability with the
Navy’s push for survivability.
Lt. Gen. Karsten Heckl, the deputy commandant for combat development and integration,
told Defense News the two services are emerging from an initial disagreement about the
cost and capabilities of this new platform.
The Marine Corps, since the early days of the light amphibious warship program, has aimed
for a price of $100 million to $130 million a copy. But the Navy—whose sailors would
drive and maintain the ship—and the Office of the Secretary of Defense wanted much
greater protection for the personnel onboard, tripling the cost and leading the Navy to plan
to buy just 18 instead of the Marines’ stated objective of 35.
“What should be a $120-$130 million ship should not be north of $350 million a copy,”
Heckl said.

Navy Medium Landing Ship (LSM) Program

Though the platforms will have to be tougher than a commercial vessel, Heckl said the
light amphib is meant to appear like a commercial craft—to “hide in plain sight.”
“The [Indo-Pacific] sea lines of communication are the most traversed sea lines in the
world; it would be a challenge for any power to surveil everything all the time in that area,”
he said. “However, if you don’t look like everything else you’re trying to blend in with,
you make your adversary’s problem set much simpler.”
The Marines don’t envision using this vessel during combat operations either, the general
said.
If there are indications a conflict may break out, the combatant commander would order
the light amphibious warships, or LAW, to quickly relocate Marines or resupply units, “and
then it goes into hiding, it goes into bed-down somewhere. Nowhere do we envision the
LAW out transiting the sea lanes in the middle of a kinetic fight.”
After several meetings between Heckl’s team and the Navy’s Program Executive Office
for Ships and the assistant secretary for research, development and acquisition, Heckl said
the group agreed “there is a lot of maneuver space” to come to an agreement and keep the
program on track for its planned fiscal 2025 start of construction.
Five companies are working on preliminary designs following a June 2021 contract award,
and the Navy-Marine team will review those designs in January, Heckl said. At that point,
with industry input in hand and an agreement in place over the right balance of survivability
versus cost, he said the team will be in a better place to decide what that balance of
survivability and affordability looks like and which companies are equipped to build that
vessel....
[Lt. Gen. David Furness, the deputy commandant for plans, policies and operations] said
the way the light amphibious warships operate would mitigate the risk China defeats them.
These ships would operate in and around the 7,000 islands of the Philippines, for example,
blending in with local commercial craft and not likely to become a target for Chinese
precision missiles.
Heckl acknowledged the ships might be operating within the range of Chinese anti-ship
missiles, but said the military too often focuses “on worst-case scenario, which drives us
into situations where the force becomes just simply unaffordable and unattainable.”44
A February 17, 2023, press report stated:
A top Marine Corps official here this week dismissed concerns the services new Medium
Landing Ships (LSM), formerly called the Light Amphibious Warship (LAW), are not
survivable enough, arguing there is always a balance.
“Survivability is a discussion that I have all the time. Survivability is not binary. It’s not
black or white, yes or no, zero or one. Things are made more survivable when you add
resources to make their movements more secure. Nothing in and of itself is ‘survivable,’”
Gen. Eric Smith, Assistant Commandant of the Marine Corps (ACMC), said here
Wednesday [February 15] during the annual WEST conference, sponsored by AFCEA
International and the U.S. Naval Institute.45

Navy Medium Landing Ship (LSM) Program

Several Navy officials recently confirmed the Navy and Marine Corps compromised on
designs for the new Landing Ship Medium (LSM) and laid out the upcoming schedule, but
also said it will be a warship that goes into contested environments....
“That has been resolved…but in general, it’s like a marriage, compromise is important.
And I will say that in the end everybody lined up on the requirements,” Tom Rivers,
executive director at program executive office, ships, said during the National Defense
Industrial Association’s (NDIA) annual Expeditionary Warfare Conference on Feb. 23.
Angela Bonner, deputy program manager of the Amphibious Assault and Connectors
program office, PMS-317, said that over the last year the two services agreed on the
requirements for LSM and the Navy completed preliminary design.46
A February 28, 2023, press report stated:
The Marine Corps will experiment on the commercial ship it leased to help decide what
capabilities its planned medium landing ships will require, officials said.
The Marine Corps Warfighting Lab plans to lease a total of three Stern Landing Vessels,
or SLVs. The first has been heavily modified and is expected to arrive in San Diego for
testing and evaluation in late March or early April. The other two are likely to be leased
next year, and may sport different modifications. After the experiments, they will become
part of a “bridging solution” for shore-to-shore operations.47
An April 4, 2023, press report states:
The U.S. Navy and Marine Corps are nearing agreement on the requirements and cost of
the Landing Ship Medium program, formerly called the Light Amphibious Warship, after
the services previously diverged in their visions for this program, officials said.
The capability development document for the program has been drafted and is working its
way through the approval process now, Brig. Gen. Marcus Annibale, the director of
expeditionary warfare on the chief of naval operations’ staff, said Tuesday [April 4] at the
Navy League’s annual Sea Air Space conference....
Vice Adm. Scott Conn, the deputy chief of naval operations for warfighting requirements
and capabilities, said during the same panel discussion that there had been a “healthy
friction” over the requirements and cost of the ship but that “there is no daylight between
us” on the importance of getting this small ship out to the fleet.
Lt. Gen. Karsten Heckl, the deputy commandant of the Marine Corps for combat
development and integration, said during the panel discussion that his office, working with
Conn’s and Annibale’s teams and the Program Executive Office for Ships, “found some
pretty good middle ground on recoverability and vulnerability additions we’re going to put
into the medium landing ship, LSM, that I think are going to be very helpful.”
“A very large part of the concept initially was, low cost, large numbers, hide in plain sight.
We did not want to look like a military vessel. We’re talking about the most traversed
maritime lanes in the world; we needed to look and sound like other vessels, to make it a
little more difficult” for China or other adversaries to detect Marines on these ships.

Navy Medium Landing Ship (LSM) Program

Though the discussions with the Navy and the Office of the Secretary of Defense had
previously led to much greater requirements for capability and survivability, and therefore
much greater cost, “we’re coming back around to the size and correspondently the cost …
where we initially had our sights,” Heckl said....
Annibale said PEO Ships commander Rear Adm. Tom Anderson will host an industry
engagement day after the capability development document is signed. He hopes this will
be a chance for the Navy and Marines to explain what they want to do with this ship and
why, which may inspire better ideas from engineers than will the thick stack of paper
outlining the formal requirements.48

Acquisition Strategy
Overview
The Navy’s baseline preference is to have a single shipyard build all the ships in the LSM
program, but the Navy is open to having LSMs built in multiple yards to the same design if doing
so could permit the program to be implemented more quickly and/or less expensively.50 As noted
earlier, the Navy’s FY2024 budget submission states that the contract for the construction of the
first LSM would be awarded in March 2025.
Reported July 2020 Contract Awards
An October 6, 2020, press report stated that the Navy in July 2020 awarded contracts for LSM
concept design studies to 15 firms, with the studies due in November 2020. According to the
press report, the 15 companies awarded contracts included Austal USE, BMT Designers,
Bollinger Shipyards, Crescere Marine Engineering, Damen, Hyak Marine, Independent Maritime
Assessment Associates, Nichols Brothers Boat Builders, Sea Transport, Serco, St John
Shipbuilding, Swiftships, Technology Associates, Thoma-Sea, and VT Halter Marine. The studies
reportedly were intended to help inform concepts of operation, technical risk, and cost estimates
for the LSM program, in support of a planned lead-ship contract award in FY2022. An August 27,
2020, press report states
The Navy and Marine Corps’ new Light Amphibious Warship program is already in
industry studies, with the service pushing ahead as quickly as possible in an
acknowledgement that they’re already behind in their transformation of the force.
Maj. Gen. Tracy King, the director of expeditionary warfare on the chief of naval
operations’ staff (OPNAV N95), said today that LAW was perhaps the most important
investment the Marine Corps was making to optimize itself for expeditionary advance base
operations (EABO).
“Having these LAWs out there as an extension of the fleet, under the watchful eye of our
Navy, engaging with our partners and allies, building partner capacity, is what I think we
need to be doing right now. I think we’re late to need with building the Light Amphibious
Warship, which is why we’re trying to go so quickly,” he said, saying that N95 was copying
the surface warfare directorate’s playbook from the frigate program, which moved quickly

50 The Q&A document from the Navy’s April 9, 2020, industry day on the LAW program (see footnote 29) states
Q [from industry]: Once [the industry] studies are done, what is the likelihood of [the Navy
making] multiple [contract] awards [for the next stage]?
A [from Navy]: When the [industry] studies are done, there will be multiple [contract] awards for
preliminary design [work]. Then [the Navy will] down select for a [preferred] prototype. [There is]
No plan for [building the ships at] multiple [ship]yards and [building them to multiple] designs like
[the] LCS [Littoral Combat Ship program]. It’s too hard of a logistics tail [to provide lifecycle
support for ships built to multiple designs]. But options are open if it is cheaper/faster.
Q [from industry]: Do you envision something similar to LCS variance [sic: variants]? Multiple
yards and designs?
A [from Navy]: No, it involves too much logistics and O&S [operation and support costs]. This
drives overall costs initially [i.e., locks higher life-cycle support costs into the program from the
outset of the program] and we’re not trying to go down that path. As we’ve said before, if studies
tell us we are wrong, if it’s affordable and fields faster, then we won’t ignore it. The data and cost
drivers will help us decide. The Government wants to field [the ships] as rapidly as possible, and
we believe that using multiple yards is not the best and most affordable path.

November 2020 Press Report About Concept Designs
A November 9, 2020, press report stated that, as part of its LSM industry studies, the Navy had
received nine LSM concept designs from 16 design firms and shipyards, some of which have
paired into teams. The report quoted a Navy official as stating that the following firms were
participating in the industry studies: Austal USA, BMT Designers, Bollinger Shipyards, Crescere
Marine Engineering, Damen, Hyak Marine, Independent Maritime Assessment Associates,
Nichols Brothers Boat Builders, Sea Transport, Serco, St. John Shipbuilding, Swiftships,
Technology Associates Inc., Thoma-Sea, VT Halter Marine and Fincantieri.53 A November 19,

A January 11, 2021, press report stated
The Navy and Marine Corps are quickly seeking new ideas that allow Marines to support
the Navy in sea control and other maritime missions, including the rapid acquisition of a
light amphibious ship and a movement toward using Marine weapons while at sea.
Maj. Gen. Tracy King, the director of expeditionary warfare on the chief of naval
operations’ staff (OPNAV N95), told USNI News during a Jan. 8 media call that the
services are moving quickly to buy their first light amphibious warship (LAW) in Fiscal
Year 2022, as outlined in the recent long-range shipbuilding plan.
“We’re moving out at flank speed; I got a chance to brief the CNO and the commandant
recently, and they told me to maintain course and heading,” he said during the media call
ahead of the annual Surface Navy Association symposium.
“We’re going through the formal JCIDS (Joint Capabilities Integration and Development
System) process right now. [Naval Sea Systems Command] has completed its second
industry studies, and we’re working on all those documents.”
For now, 10 or 11 industry teams remain involved in the NAVSEA competition, which
recently held a second round of industry studies. NAVSEA is working with those teams to
help iterate what King called “novel” designs, to ensure they were the right size and could

achieve cost and performance requirements. Mid next year, he said, NAVSEA would
downselect to three teams for full design, and then would downselect to just one to build
the first LAW in late FY2022.
“My suspicion is that we’ll begin [research, development, test and evaluation] next year,
and then we are aiming at lead ship construction in FY ’22, it’s going to be late in FY ’22
,but I still consider that pretty fast,” King said.
“We’re just going to build one, get that out and start playing with it. We’ll probably build
one the next year because we’ve got to get the doctrine right. The [Marine Littoral
Regiments] are going to start coming online at about the same time – first one’s in Hawaii,
we’ll get it out there and let them play with it. And then we’ll go into a build profile of, I
don’t know, probably four or five a year or something like that is what we’re going to aim
for.”55
June 2021 Contract Awards
A June 17, 2021, press report states
The Navy this week issued “concept design” contracts to five companies for the Light
Amphibious Warship ahead of the Fiscal Year 2023 design selection, a service spokesman
confirmed to USNI News.
Fincantieri, Austal USA, VT Halter Marine, Bollinger and TAI Engineers were selected
for the contracts, Naval Sea Systems Command spokesman Alan Baribeau said.
“A Concept Studies (CS) contract has been awarded to five offerors with a follow-on
option for Preliminary Design (PD),” Baribeau said in a statement. “The CS/PD efforts
include engineering analyses, tradeoff studies, and development of engineering and design
documentation defining concepts studies/preliminary designs.”
The Navy did not disclose the amount of money each company received to perform the
work, but Baribeau confirmed to USNI News that the total combined amount of the
contracts was less than $7.5 million.56
A February 10, 2022, press report states
Moving ahead, the services [i.e., the Navy and Marine Corps] expect a “full and open
competition” once they issue the request for proposals for the detail[ed] design and
construction phase, according to Tom Rivers, the executive director of the amphibious,
auxiliary and sealift office within the Program Executive Office for Ships.
After issuing five companies “concept design” contracts last year, those same five
companies recently received options for the preliminary design phase, Rivers said. The
companies working on the preliminary design are Fincantieri, Austal USA, VT Halter
Marine, Bollinger and TAI Engineers.
“So LAW—the initial thought process is based upon parent designs [i.e., existing ship
designs from which the design for LAW could be derived] that are already out there in the
world today to, again, to reduce our risks,” Rivers said at the conference. “As new
requirements are generated out of the Pentagon, we actually are sharing those with the
shipyards so they can kind of see what we’re thinking about how it evolves over time and

then they can kind of build that into the—and they come back to us and say, ‘hey here’s
the impact of that particular change on our configuration.’ Either it’s small or large and
then we take that in consideration into the final requirements.”
This type of process is helping the Navy determine what it can do with the various parent
designs, Rivers said.57
FY2024 Funding Request
The Navy’s proposed FY2024 budget requests $14.7 million in research and development
funding for the program. The funding is requested in Project 4044 (Medium Landing Ship) of PE
(Program Element) 0603564N (Ship Preliminary Design and Feasibility Studies), which is line 46
in the Navy’s FY2024 research and development account.
Issues for Congress
The LSM program poses a number of potential oversight matters for Congress, including those
discussed briefly in the sections below.
Analysis of Alternatives (AOA)
One issue for Congress concerns the analysis of alternatives (AOA) for the LSM program. An
AOA is a formal study that examines broad options for meeting a mission requirement,
determines whether that requirement would be best met through the procurement of a new
weapon system or platform (e.g., ship or aircraft), and if so, what that general features of that new
weapon system or platform should be. A June 2022 Government Accountability Office (GAO)
report assessing selected DOD weapon acquisition programs stated the following in its entry on
the LSM program:
The Navy plans to approve an analysis of alternatives—a key document that will help Navy
leadership decide whether a new ship class is necessary to meet mission needs—in support
of the program in early 2022. Nonetheless, the Navy is already in the process of defining
requirements for LAW and starting ship design efforts. Our prior work shows that moving
forward before Navy leadership validates the need for a new ship class can increase the
risk of acquiring ships that do not cost-effectively meet mission needs....
The [LSM] program office stated that the Navy is reviewing the analysis of alternatives
report in advance of a meeting to decide whether it will approve the analysis of alternatives
results. It added that moving forward with defining requirements through studies and
collaboration with industry on preliminary design concepts are common Navy best
practices being used to ensure LAW delivers the capability needed to support the Marine
Littoral Regiments.58
Future Amphibious Ship Force-Level Goal
Another issue for Congress concerns the future amphibious ship force-level goal, which could
affect future procurement quantities for LSMs. As noted earlier, the issue of the future

Navy Medium Landing Ship (LSM) Program

amphibious ship force level goal reportedly has been a matter of debate within the Defense
Department.59 A related potential oversight issue for Congress concerns how the LSM would fit
into the Navy’s overall future fleet architecture. Potential oversight questions for Congress
include the following:
 What is the analytical basis for the envisioned procurement quantity of 18 to 35
LSMs?60
 How well can the cost-effectiveness of a force of 18 to 35 LSMs be assessed if
the remainder of the Navy’s amphibious ship fleet architecture is not yet fully
known?
A February 16, 2023, press report stated:
The Marine Corps’ latest requirements call for nine smaller amphibious ships per regiment
to shuttle Marines and equipment between islands and shorelines, service officials said
today.
The service has said for months that it needs 35 Landing Ship Mediums—previously
known as the Light Amphibious Warship—for the type of operations it envisions in the
Indo-Pacific region. The idea is that the three Marine Littoral Regiments operating in the
Indo-Pacific would each have nine LSMs, while leaving room for eight ships that would
inevitably get tied up in maintenance periods, according to a new Marine Corps video about
requirements.
The Marine Corps came up with this requirement after modeling and simulations, deputy
commandant for combat development and integration Lt. Gen. Karsten Heckl said Tuesday
[Feruary 14] at the WEST 2023 conference, co-hosted by the U.S. Naval Institute and
AFCEA.
“It doesn’t necessarily need to be a Marine Littoral Regiment,” he said. “So the square
footage, the cargo—and that’s where we came up with the requirements—berthing, fuel,
all of it,” Heckl said.
The requirements focused on tonnage, square footage for cargo and the need for Marines
to move around the region on their own, without the benefit of long runways or ports and
piers....
While the Marine Corps says it needs 35 LSMs, Chief of Naval Operations Adm. Mike
Gilday’s navigation plan called for 18 LAWs, the previous name for the program. Asked
about that difference, Heckl said he and deputy chief of naval operations for warfighting
requirements and capabilities (OPNAV N9) Vice Adm. Scott Conn crafted requirement
language that says the ultimate requirement is 35, but “the initial operational inventory will
be 18.”61

The Navy is planning to secure a plan to procure 18 Light Amphibious Warship (LAW) in
the department’s 2025 budget planning process, a top Navy official said last week during
the Surface Navy Association’s annual symposium on Jan. 11
During a panel discussion, Marine Brig. Gen. Marcus Annibale, director of expeditionary
warfare (OPNAV N95), reiterated the Chief of Naval Operations NAVPLAN set a goal of
18 LAWs that the service intends to “lock in” in the Defense Department’s Program
Objective Memorandum [POM] [for the fiscal year] 2025 [budget submission].62
The issue of the future amphibious ship force-level goal is discussed further in the CRS report on
the Navy’s LPD-17 Flight II and LHA-class amphibious shipbuilding programs.63
Force Design 2030 and EABO Operational Concept
Another potential oversight issue for Congress concerns the merits of Force Design 2030 and the
EABO operational concept that the LSM is intended to help implement. Debate on the merits of
Force Design 2030 and the EABO concept has been vigorous and concerns issues such as
 whether Force Design 2030 and the EABO concept are focused too exclusively
on potential conflict scenarios with China at the expense of other kinds of
potential Marine Corps missions;
 the ability of Marine forces to gain access to the islands from which they would
operate;
 the ability to resupply Marine forces that are operating on the islands;
 the survivability of Marine forces on the islands and in surrounding waters;
 how much of a contribution the envisioned operations by Marine forces would
make in contributing to overall U.S. sea-denial operations; and
 potential alternative ways of using the funding and personnel that would be
needed to implement EABO.64
Potential oversight questions for Congress include the following:
 What are the potential benefits, costs, and risks of the EABO concept?
 What work have the Navy and Marine Corps done in terms of analyses and war
games to develop and test the concept?
 Would EABO be more cost effective to implement than other potential uses of
the funding and personnel?

Navy Medium Landing Ship (LSM) Program

Accuracy of Estimated Procurement Cost
Another potential oversight issue for Congress concerns the accuracy of the Navy’s estimated
procurement cost target for the LSM. Potential oversight questions for Congress include the
following:
 Is the Navy’s estimate reasonable, given the features the Navy wants the ship to
have?
 As the LSM program proceeds, will the operational requirements (and thus
procurement cost) of the LSM increase?
Potential Alternative of Adapting Existing Army LSVs
Another potential issue for Congress is whether at least some portion of the operational
requirements for the LSM program could be met cost effectively met by adapting existing U.S.
military ships rather than building new LSMs. Some observers, for example, argue that at least
some portion of the operational requirements for the LSM program could be met more cost-
effectively by transferring existing Army watercraft known as Logistics Support Vessels (LSVs)
(Figure 4) to the Navy and adapting these LSVs to the LSM mission.

A June 22, 2020, opinion piece discussing this idea states
The Navy intends to acquire up to 30 new light amphibious warships, or LAW, to support
new Marine Corps requirements.… Rather than accepting a new amphibious design built
from the ground up, however, decision-makers should take advantage of the fact that many

Navy Medium Landing Ship (LSM) Program

key requirements of the new vessels are very similar to the capabilities of vessels operated
by U.S. Army Transportation Command.
The Navy and Marine Corps should delay any new construction and immediately acquire
some of these existing vessels to drive experimentation and better inform their
requirements for the LAW program….
U.S. Army Transportation Command has over 100 vessels, and dozens have similar
capabilities to those required of the LAW. The Army’s LCU-2000s, also called the
Runnymede-class large landing crafts, are smaller, with roughly half of the cargo space
designed for the LAW and slightly slower, but they boast nearly double the range. The
Runnymede-class vessels have nearly 4,000 square feet of cargo space and can travel 6,500
miles when loaded and at 12 knots; and they can unload at the beach with their bow ramp.
The Army’s General Frank S. Besson-class logistics support vessels are larger than the
future LAW, at 273 feet in length but can claim 10,500 square feet of cargo space and a
6,500-mile range loaded to match the LCU-2000. These vessels also have both a bow and
stern ramp for roll-on/roll-off capability at the beach or ship-to-ship docking at sea. The
version built for the Phillipine military also has a helipad.
Army Transportation Command has 32 Runnymede-class and eight General Frank S.
Besson-class vessels in service. Mostly built in the 1990s, both classes of vessel have many
years left in their life expectancy and more than meet the Navy’s 10-year life expectancy
for the LAW.
These vessels are operable today and could be transferred from the Army to the Navy or
Marine Corps tomorrow. In fact, the Army was attempting to divest itself of these
watercraft less than a year ago, which underscores the importance of this opportunity even
further. Congress is firmly set against the Army getting rid of valuable, seaworthy vessels
and has quashed all of the Army’s efforts to do so thus far, but transferring this equipment
to the Navy is a reasonable course of action that should satisfy all parties involved….
By acquiring a watercraft that meets most of their requirements from the Army, the Navy
and Marine Corps simultaneously fill current capability gaps and obtain an invaluable
series of assets they can use to support the evaluation and experimentation of new designs
and concepts. This will allow Navy and Marine leaders to give their units the maximum
amount of time to evaluate and experiment with new designs to get a better idea of what
they need both in future amphibious craft as well as operational and support equipment….
Often overlooked, the availability of surplus vessels is absolutely critical to the process of
developing new technologies, developing the tactics to employ them, conducting training,
and providing decision-makers the requisite capacity to remain flexible in the face of
unexpected challenges….
[The Navy and Marine Corps have] long been in need of a boost in their amphibious
capabilities so as to be better positioned to meet the demands of today and prepare for the
challenges of tomorrow, and taking possession of the Army’s Runnymede- and Frank S.
Benson-class vessels is a solution on a silver platter.65
In a May 2022 update to its Force Design 2030 plan, the Marine Corps stated that it would
“Provide and sustain bridging solutions for littoral mobility for MLR experimentation and
training until the LAW is fielded,” and that

Navy Medium Landing Ship (LSM) Program

While we await the delivery of LSM, which post-dates the planned operational readiness
of our MLRs, we will explore a family of systems bridging plan—including, Expeditionary
Transfer Dock (ESB), Expeditionary Fast Transport (T-EPF), Landing Craft Utility (LCU),
and leased hulls—that can provide a basic level of mobility. Although not optimal, such
vessels will provide both operational capability and a sound basis for live experimentation
and refining detailed requirements for the LSM program.66
In June 2022, the Marine Corps stated that pending the delivery of the first LSMs, it will likely
use three civilian stern landing vessels to inform the design of the LSM hull form and experiment
with and confirm operational concepts for the LSM program.67
Potential questions for Congress include the following:
 How many of these watercraft would be available for transfer to the Navy for use
in meeting the operational requirements of the LSM program?
 How do the capabilities of these watercraft compare with those required for the
LSM?
 How much remaining service life do these watercraft have?
 Given the number of these watercraft that would be available for transfer to the
Navy, their operational capabilities, and their remaining service life, what portion
of the LSM program’s operational requirements could transferred watercraft
meet? How many LSMs, if any, would still need to be built to fully or
substantially meet the LSM program’s operational requirements?
 How do the acquisition and operation and support (O&S) costs of these
watercraft compare to the estimated acquisition and O&S costs of the LSMs they
would replace?
 Taking into account capabilities, acquisition costs, and O&S costs, how does the
cost effectiveness of an approach involving the transfer of these watercraft
compare to that of the Navy’s baseline approach of meeting the LSM program’s
requirements through the acquisition of 24 to 35 new LSMs?
 What would be the potential industrial-base implications of using transferred
watercraft to meet at least some portion of the LSM program’s operational
needs?
Industrial-Base Implications
Another potential oversight issue for Congress concerns the potential industrial-base implications
of the LSM program. In recent years, all Navy amphibious ships have been built by the Ingalls
shipyard of Pascagoula, MS, a part of Huntington Ingalls Industries (HII/Ingalls). As noted
earlier, LSMs could be built by multiple U.S. shipyards.68 Potential oversight questions for
Congress include the following:

 What implications might the LSM program have for the distribution of Navy
shipbuilding work among U.S. shipyards?
 How many jobs would the LSM program create at the shipyard that builds the
ships, at associated supplier firms, and indirectly in surrounding communities?
 In a situation of finite defense resources, what impact, if any, would funding the
procurement of LSMs have on funding available for procuring other types of
amphibious ships, and thus on workloads and employment levels at HII/Ingalls,
its associated supplier firms, and their surrounding communities?69

appropriations for the Navy’s shipbuilding account (the Shipbuilding and Conversion, Navy account) typically contains
these provisos: “ … Provided further, That none of the funds provided under this heading for the construction or
conversion of any naval vessel to be constructed in shipyards in the United States shall be expended in foreign facilities
for the construction of major components of such vessel: Provided further, That none of the funds provided under this
heading shall be used for the construction of any naval vessel in foreign shipyards….”
69 Two observers argue that shifting the Navy to a fleet architecture that includes a larger proportion of smaller ships
would have beneficial impacts on U.S. shipbuilding industry’s ability to support Navy shipbuilding needs. See Bryan
