SUMMARY

China Naval Modernization: Implications for

U.S. Navy Capabilities—Background and Issues

for Congress

RL33153

April 24, 2025

Ronald O'Rourke

Specialist in Naval Affairs

China’s military modernization effort, including its naval modernization effort, is the top focus of

U.S. defense planning and budgeting. China’s naval modernization effort has been underway for

about 30 years, since the early to mid-1990s, and has transformed China’s navy into a much more

modern and capable force. China’s navy is a formidable military force within China’s near-seas region, and it is conducting a

growing number of operations in the broader waters of the Western Pacific, the Indian Ocean, and waters around Europe.

China’s navy is, by far, the largest of any country in East Asia, and sometime between 2015 and 2020 it surpassed the U.S.

Navy in numbers of battle force ships, meaning the types of ships that count toward the quoted size of the U.S. Navy. DOD

states that China’s navy “is the largest navy in the world with a battle force of over 370 platforms [i.e., ships], including

major surface combatants, submarines, ocean-going amphibious ships, mine warfare ships, aircraft carriers, and fleet

auxiliaries. Notably, this figure does not include approximately 60 HOUBEI-class patrol combatants that carry anti-ship

cruise missiles (ASCM). The… overall battle force [of China’s navy] is expected to grow to 395 ships by 2025 and 435 ships

by 2030.” The U.S. Navy, by comparison, included 296 battle force ships as of September 30, 2024, and the Navy’s FY2025

budget submission projects that the Navy will include 294 battle force ships by the end of FY2030. U.S. military officials and

other observers are expressing concern or alarm regarding the pace of China’s naval shipbuilding effort, the capacity of

China’s shipbuilding industry compared with the capacity of the U.S. shipbuilding industry, and trend lines regarding the

relative sizes and capabilities of China’s navy and the U.S. Navy.

China’s naval modernization effort encompasses a wide array of ship, aircraft, weapon, and C4ISR (command and control,

communications, computers, intelligence, surveillance, and reconnaissance) acquisition programs, as well as improvements

in logistics, doctrine, personnel quality, education and training, and exercises. China’s navy currently has certain limitations

and weaknesses, which it is working to overcome. China’s military modernization effort, including its naval modernization

effort, is assessed as being aimed at developing capabilities for, among other things, addressing the situation with Taiwan

militarily, if need be; achieving a greater degree of control or domination over China’s near-seas region, particularly the

South China Sea; defending China’s commercial sea lines of communication (SLOCs), particularly those linking China to the

Persian Gulf; displacing U.S. influence in the Western Pacific; and asserting China’s status as the leading regional power and

a major world power. Observers believe China wants its navy to be capable of acting as part of an anti-access/area-denial

(A2/AD) force—a force that can deter U.S. intervention in a conflict in China’s near-seas region over Taiwan or some other

issue, or failing that, delay the arrival or reduce the effectiveness of intervening U.S. forces.

The U.S. Navy has taken a number of actions to counter China’s naval modernization effort. Among other things, the U.S.

Navy has shifted a greater percentage of its fleet to the Pacific; assigned its most-capable new ships and aircraft to the

Pacific; maintained or increased general presence operations, training and developmental exercises, and engagement and

cooperation with allied and other navies in the Indo-Pacific; increased the planned future size of the Navy; initiated,

increased, or accelerated numerous programs for developing new military technologies and acquiring new ships, aircraft,

unmanned vehicles, and weapons; and developed new operational concepts for countering PRC maritime A2/AD forces. The

issue for Congress is whether to approve, reject, or modify the Trump Administration’s proposed U.S. Navy plans, budgets,

and programs for responding to China’s naval modernization effort.

China Naval Modernization: Implications for U.S. Navy Capabilities

Introduction

Issue for Congress

This report provides background information and issues for Congress on the naval modernization

effort of the People’s Republic of China (PRC, or China) and its implications for U.S. Navy

capabilities. China’s military modernization effort, including its naval modernization effort, is the

top focus of U.S. defense planning and budgeting.1 The issue for Congress is whether to approve,

reject, or modify the Trump Administration’s proposed U.S. Navy plans, budgets, and programs

for responding to China’s naval modernization effort. Congress’s decisions on this issue could

affect U.S. Navy capabilities and funding requirements, and the U.S. defense industrial base.

Sources and Terminology

This report is based on unclassified open-source information, such as the annual Department of

Defense (DOD) report to Congress on military and security developments involving China,2 a

2019 Defense Intelligence Agency (DIA) report on China’s military power,3 a 2015 Office of

Naval Intelligence (ONI) report on China’s navy,4 published reference sources such as IHS Jane’s

Fighting Ships,5 and press reports.

For convenience, this report uses the term China’s naval modernization effort to refer to the

modernization not only of China’s navy, but also of PLA forces outside China’s navy that can be

used to counter U.S. naval forces operating in the Western Pacific, such as land-based anti-ship

ballistic missiles (ASBMs), land-based surface-to-air missiles (SAMs), land-based Air Force

aircraft armed with anti-ship cruise missiles (ASCMs), and land-based long-range radars for

detecting and tracking ships at sea.

China’s military is formally called the People’s Liberation Army (PLA). Its navy is called the

PLA Navy, or PLAN (also abbreviated as PLA[N]), and its air force is called the PLA Air Force,

or PLAAF. The PLA Navy includes an air component that is called the PLA Naval Air Force, or

PLANAF. China refers to its ballistic missile force as the PLA Rocket Force (PLARF).

This report uses the term China’s near-seas region to refer to the Yellow Sea, East China Sea, and

South China Sea—the waters enclosed by the so-called first island chain. The so-called second

island chain encloses both these waters and the Philippine Sea that is situated between the

Philippines and Guam.6

China Naval Modernization: Implications for U.S. Navy Capabilities

Background

Brief Overview of China’s Naval Modernization Effort

Key overview points concerning China’s naval modernization effort include the following:

•

•

•

•

China’s naval modernization effort, which forms part of a broader PRC military

modernization effort that includes several additional areas of emphasis,7 has been

underway for about 30 years, since the early to mid-1990s, and has transformed

China’s navy into a much more modern and capable force.

China’s navy is a formidable military force within China’s near-seas region, and

it is conducting a growing number of operations in more-distant waters, including

the broader waters of the Western Pacific, the Indian Ocean, and waters around

Europe.

China’s navy is, by far, the largest of any country in East Asia, and as shown in

Table 2, sometime between 2015 and 2020, China’s navy surpassed the U.S.

Navy in numbers of battle force ships (meaning the types of ships that count

toward the quoted size of the U.S. Navy), making China’s navy the numerically

largest in the world. DOD states, “The PLAN is the largest navy in the world

with a battle force of over 370 platforms [i.e., ships], including major surface

combatants, submarines, ocean-going amphibious ships, mine warfare ships,

aircraft carriers, and fleet auxiliaries. Notably, this figure does not include

approximately 60 HOUBEI class patrol combatants that carry anti-ship cruise

missiles (ASCM). The PLAN’s overall battle force is expected to grow to 395

ships by 2025 and 435 ships by 2030. Much of this growth will be in major

surface combatants.”8 The U.S. Navy, by comparison, included 296 battle force

ships as of September 30, 2024, and the Navy’s FY2025 budget submission

projects that the Navy will include 294 battle force ships by the end of FY2030.9

U.S. military officials and other observers are expressing concern or alarm

regarding the pace of China’s naval shipbuilding effort, the capacity of China’s

shipbuilding industry compared with the capacity of the U.S. shipbuilding

industry, and trend lines regarding the relative sizes and capabilities of China’s

navy and the U.S. Navy.10 China’s navy is viewed as posing a major challenge to

7 Other areas of emphasis in China’s military modernization effort include space capabilities, cyber and electronic

warfare capabilities, ballistic missile forces, and aviation forces, as well as the development of emerging militaryapplicable technologies such as hypersonics, artificial intelligence, robotics and unmanned vehicles, directed-energy

technologies, and quantum technologies. For more on China’s military modernization effort in general, see CRS Report

R46808, China’s Military: The People’s Liberation Army (PLA), by Caitlin Campbell. For a discussion of advanced

military technologies, see CRS In Focus IF11105, Defense Primer: Emerging Technologies, by Kelley M. Sayler. U.S.China competition in military capabilities in turn forms one dimension of a broader U.S.-China strategic competition

that also includes political, diplomatic, economic, technological, and ideological dimensions.

the U.S. Navy’s ability to achieve and maintain wartime control of blue-water

ocean areas in the Western Pacific—the first such challenge the U.S. Navy has

faced since the end of the Cold War. China’s navy forms a key element of a PRC

challenge to the long-standing status of the United States as the leading military

power in the Western Pacific.

China’s naval ships, aircraft, and weapons are much more modern and capable

than they were at the start of the 1990s, and are comparable in many respects to

those of Western navies. DOD states, “Today, the PLAN is largely composed of

modern multi-role platforms featuring advanced anti-ship, anti-air, and antisubmarine weapons and sensors.”11 ONI states that “Chinese naval ship design

and material quality is in many cases comparable to [that of] USN [U.S. Navy]

ships, and China is quickly closing the gap in any areas of deficiency.”12

China’s naval modernization effort encompasses a wide array of platform and

weapon acquisition programs, including anti-ship ballistic missiles (ASBMs),

anti-ship cruise missiles (ASCMs), submarines, surface ships, aircraft, unmanned

vehicles (UVs),13 and supporting C4ISR (command and control,

communications, computers, intelligence, surveillance, and reconnaissance)

systems. China’s naval modernization effort also includes improvements in

logistics, doctrine, personnel quality, education and training, and exercises.14

China’s military modernization effort, including its naval modernization effort, is

assessed as being aimed at developing capabilities for, among other things,

addressing the situation with Taiwan militarily, if need be; achieving a greater

degree of control or domination over China’s near-seas region, particularly the

South China Sea; enforcing China’s view that it has the right to regulate foreign

military activities in its 200-mile maritime exclusive economic zone (EEZ);15

defending China’s commercial sea lines of communication (SLOCs), particularly

those linking China to the Persian Gulf; displacing U.S. influence in the Western

Pacific; and asserting China’s status as the leading regional power and a major

world power.16 Additional missions for China’s navy include conducting

maritime security (including antipiracy) operations, evacuating PRC nationals

from foreign countries when necessary, and conducting humanitarian

assistance/disaster response (HA/DR) operations.

Observers believe China wants its navy to be capable of acting as part of an antiaccess/area-denial (A2/AD) force—a force that can deter U.S. intervention in a

conflict in China’s near-seas region over Taiwan or some other issue, or failing

that, delay the arrival or reduce the effectiveness of intervening U.S. forces.

The planned ultimate size and composition of China’s navy is not publicly

known. In contrast to the U.S. Navy, China does not release a navy force-level

goal or detailed information about planned ship procurement rates, planned total

ship procurement quantities, planned ship retirements, and resulting projected

force levels.

Although China’s naval modernization effort has substantially improved China’s

naval capabilities, China’s navy currently is assessed as having limitations or

weaknesses in certain areas,17 including joint operations with other parts of

China’s military,18 anti-submarine warfare (ASW), long-range targeting, a limited

capacity for carrying out at-sea resupply of combatant ships operating far from

home waters,19 a limited number of overseas bases and support facilities,20 a need

to train large numbers of personnel to crew its new ships,21 non-commissioned

officers (NCOs) that are not empowered by unit commanders through mission

command to achieve a commander’s intent,22 and a lack of recent combat

nevertheless be sufficient for performing missions of interest to China’s leaders.

Dibb, “Be Alert to China’s Military Weaknesses,” Strategist, December 1, 2023.

The use of a dual command structure in the crews of larger PLA Navy ships, involving both a commanding officer and

a political officer, has been raised as a source of potential reduced command effectiveness in certain tactical situations.

24 For example, China’s naval shipbuilding programs were previously dependent on foreign suppliers for some ship

components. ONI, however, states that “almost all weapons and sensors on Chinese naval ships are produced incountry, and China no longer relies on Russia or other countries for any significant naval ship systems.” (Source:

Naval Construction Trends vis-à-vis U.S. Navy Shipbuilding Plans, 2020-2030,” February 2020, pp. 2-3. Provided by

Senate Armed Services Committee to CRS and CBO on March 4, 2020, and used in this CRS report with the

committee’s permission.) Regarding the ASW capabilities of China’s Navy, DOD states

The PLAN is improving its anti-submarine warfare (ASW) capabilities through the development of

its surface combatants and special mission aircraft but continues to lack a robust deep-water ASW

capability.

China Naval Modernization: Implications for U.S. Navy Capabilities

•

As China’s navy reduces its weaknesses and limitations, it may become sufficient

to perform a wider array of potential missions.

In addition to modernizing its navy, China has substantially increased the size

and capabilities of its coast guard. DOD states that China’s coast guard is “the

largest maritime law enforcement fleet in the world.”25 China also operates a

sizeable maritime militia that includes a large number of fishing vessels. China

relies primarily on its maritime militia and coast guard to assert and defend its

maritime claims in its near-seas region, with the navy operating over the horizon

as a potential backup force.26

Numbers of Ships; Comparisons to U.S. Navy

Overview

DOD states

The PLAN is the largest navy in the world with a battle force of over 370 platforms [i.e.,

ships], including major surface combatants, submarines, ocean-going amphibious ships,

mine warfare ships, aircraft carriers, and fleet auxiliaries. Notably, this figure does not

include approximately 60 HOUBEI class patrol combatants that carry anti-ship cruise

missiles (ASCM). The PLAN’s overall battle force is expected to grow to 395 ships by

2025 and 435 ships by 2030. Much of this growth will be in major surface combatants.27

DIA states that “the PLAN is rapidly retiring older, single-mission warships in favor of larger,

multimission ships equipped with advanced antiship, antiair, and antisubmarine weapons and

sensors and C2 [command and control] facilities.”28

Another set of observers states

China’s rapid military buildup has left the People’s Liberation Army Navy (PLAN) poised

to overtake the U.S. Navy in several measures of maritime might more quickly than

sometimes assumed. If China continues to expand its fleet at the current pace and the

United States does not revitalize its shipbuilding industry, China will grow increasingly

likely to emerge victorious from interstate war, especially a prolonged great power war….

25 DOD states that

The CCG’s continued expansion and modernization makes it the largest maritime law enforcement

fleet in the world. Newer CCG vessels are larger and more capable, enabling them to operate

farther off shore and remain on station longer. The CCG has over 150 regional and oceangoing

patrol vessels (more than 1,000 tons). These larger vessels include over 20 corvettes transferred

from the PLAN, which were modified for CCG operations. The newer, larger CCG vessels are

equipped with helicopter facilities, high-capacity water cannons, multiple interceptor boats and

guns ranging from 30 mm to 76 mm. Revised estimates indicate the CCG operates more than 50

regional patrol combatants (more than 500 tons), which can be used for limited offshore operations,

and an additional 300 coastal patrol craft (100 tons to 499 tons). In 2023 and early 2024, the CCG

launched seven offshore patrol ships as well as two additional patrol ships based on a large salvage

ship design. Several more offshore patrol ships are likely under construction.

China Naval Modernization: Implications for U.S. Navy Capabilities

China now possesses the world’s largest maritime fighting force, operating 234 warships

[excluding auxiliary and support ships] to the U.S. Navy’s 219 [warships excluding

auxiliary and support ships].29

Ultimate Size and Composition of China’s Navy Not Publicly Known

The planned ultimate size and composition of China’s navy is not publicly known. The U.S. Navy

makes public its force-level goal and regularly releases a 30-year shipbuilding plan that shows

planned procurements of new ships, planned retirements of existing ships, and resulting projected

force levels, as well as a five-year shipbuilding plan that shows, in greater detail, the first five

years of the 30-year shipbuilding plan.30 In contrast, China does not release a navy force-level

goal or detailed information about planned ship procurement rates, planned total ship

procurement quantities, planned ship retirements, or resulting projected force levels. The ultimate

size and composition of China’s navy might be an unsettled and evolving issue among China’s

military and political leaders. One observer states that “it seems the majority of past foreign

projections of Chinese military and Chinese navy procurement scale and speed have been

underestimates…. All military forces have a desired force requirement and a desired ‘critical

mass’ to aspire toward. Whether the Chinese navy is close to its desired force or not, is of no

small consequence.”31

Number of Ships Is a One-Dimensional Measure, but Trends in Numbers Can

Be of Value Analytically

Relative U.S. and PLA naval capabilities are sometimes assessed by showing comparative

numbers of U.S. and PLA ships (or comparative aggregate fleet displacements [i.e, tonnages]).

Although the total number of ships in a navy (or a navy’s aggregate displacement) is relatively

easy to calculate, it is a one-dimensional measure that leaves out numerous other factors that bear

on a navy’s capabilities and how those capabilities compare to its assigned missions. As a result,

as discussed in further detail in Appendix A, comparisons of the total numbers of ships in

China’s navy and the U.S. Navy (or aggregate displacements) are highly problematic as a means

of assessing relative U.S. and PLA naval capabilities and how those capabilities compare to the

missions assigned to the two navies. At the same time, however, an examination of trends over

time in these relative numbers of ships (or aggregate displacements) can shed some light on how

the relative balance of U.S. and PLA naval capabilities might be changing over time.

China Naval Modernization: Implications for U.S. Navy Capabilities

China for the year prior to the report’s cover date. For example, the 2005 edition of the DOD report shows

data for 2004.

Key to abbreviations: n/a = data not available in annual DOD report. SSB = ballistic missile submarines. SSN

= nuclear-powered attack submarines. SS = diesel attack submarines. CV = aircraft carriers. CG = cruisers. DD

= destroyers. FF = frigates. FFL = corvettes (i.e., light frigates). PC = missile-armed patrol craft. LST =

amphibious tank landing ship. LPD = amphibious transport dock ship. LSM = amphibious medium landing ship.

(Starting with the 2021 edition, the annual DOD report shows a combined figure for LST/LPD and LSM.)

Column for Total PLAN ship types shown to right, which shows what might be thought of as the principal

combat ships of China’s navy, does not include other PLAN ship types not shown to right, such as auxiliary and

support ships. CCG = China Coast Guard ships. U.S. total = Total U.S. Navy battle force ships, which includes

auxiliary and support ships but excludes patrol craft (although the U.S. Navy has very few patrol craft). U.S. vs.

PLAN ship types shown = total U.S. Navy battle force ships compared to the column for Total PLAN ship

types shown to right.

As can be seen in Table 1, about 84% of the net increase in the total number of PLA ships since

2004 (a net increase of 97 ships out of the total net increase of 116 ships) resulted from increases

in cruisers and destroyers (29 ships), corvettes (i.e., light frigates) (50 ships), and amphibious

ships (18 ships). The corvettes alone account for about 43% of the total net increase.

Table 1 lumps together less capable older PLA ships with more capable modern PLA ships. In

examining the numbers in the table, it can be helpful to keep in mind that for many of the types of

PLA ships shown in the table, the percentage of the ships accounted for by more capable modern

designs was growing over time, even if the total number of ships for those types was changing

little.

For reference, Table 1 also shows the total number of U.S. Navy battle force ships (BFSs),

meaning the types of ships that count toward the quoted size of the U.S. Navy, and compares it to

the total number of the types of PLA ships that are shown in the table. The result is an apples-vs.oranges comparison, because the PLA figures exclude auxiliary and support ships, while the U.S.

Navy figure includes auxiliary and support ships but excludes patrol craft (although the U.S.

Navy has very few patrol craft). Changes over time in this apples-vs.-oranges comparison,

however, can be of value in understanding trends in the comparative sizes of the U.S. and PLA

navies.

On the basis of the figures in Table 1, it might be said that in 2014, the total number of principal

combat ships in China’s navy (a figure that excludes PLAN auxiliary and support ships) surpassed

the total number of U.S. Navy battle force ships (a figure that includes U.S. Navy auxiliary and

support ships). It is important, however, to keep in mind the differences in composition between

the two navies. The U.S. Navy, for example, has many more aircraft carriers, nuclear-powered

submarines, and cruisers and destroyers, while China’s navy has many more diesel attack

submarines, frigates, and corvettes.34

Table Showing ONI Figures from February 2020

Table 2 shows comparative total numbers of PLA Navy and U.S. Navy battle force ships (BFSs),

as well as specific figures for certain types of ships that contribute toward China’s total number of

battle force ships from 2000 to 2030, with the figures for 2025 and 2030 being projections. The

figures for China’s ships are taken from an ONI information paper of February 2020. (As noted

earlier, battle force ships are the types of ships that count toward the quoted size of the U.S. Navy.

The ONI information paper applied the same counting rules to the PLA Navy.) For China, the

total number of battle force ships shown excludes the missile-armed patrol craft (PCs) shown in

China navy battle force ships of 110, but the Navy later stated that this was a typo, and that the correct figure is

210.

As shown in Table 2, China’s navy surpassed the U.S. Navy in terms of total number of battle

force ships sometime between 2015 and 2020. As mentioned earlier in connection with Table 1,

however, it is important to keep in mind the differences in composition between the two navies.

The U.S. Navy, for example, currently has many more aircraft carriers, nuclear-powered

submarines, and cruisers and destroyers, while China’s navy currently has many more diesel

attack submarines, frigates, and corvettes.36

were provided by the Navy at the request of CRS. As with Table 1, the result is an apples-vs.oranges comparison between the PLA Navy and U.S. Navy totals, because the PLA total excludes

auxiliary and support ships, while the U.S. Navy total includes auxiliary and support ships, but

excludes patrol craft (although the U.S. Navy has very few patrol craft).

Sources: For PLA Navy ships: U.S. Navy data provided to CRS by Navy Office of Legislative Affairs, reflecting

data as of October 26, 2020. For U.S. Navy ships: U.S. Navy data—actual for 2020, and projections for

subsequent years shown in Navy’s FY2025 30-year shipbuilding plan.

As shown in Table 3, the U.S. Navy projects that between 2020 and 2040, the total number of

PLA ships of the types shown in the table will increase by 94, or about 39%, with most of that

increase (77 ships out of 94) coming from roughly equal increases in numbers of large surface

combatants (cruisers and destroyers—39 ships) and small surface combatants (frigates and

corvettes—38 ships). The total number of U.S. Navy battle force ships projected for 2040

assumes that the Navy’s FY2025 30-year shipbuilding plan is fully implemented. As shown by

Congressional Budget Office (CBO) analysis, the realized number of U.S. Navy battle force ships

in a given year has often been less than the number that was projected for that year in prior-year

editions of the Navy’s 30-year shipbuilding plan.37

As shown by CBO analysis, the realized number of U.S. Navy battle force ships in a given year

has often been less than the number that was projected for that year in prior-year editions of the

Navy’s 30-year shipbuilding plan.38

missiles. A ship’s number of VLS cells is one measure of the ship’s weapon capacity, though not a

complete one, as ships can be armed with additional missiles that are fired from deck-mounted

box launchers rather than VLS cells, and ships can be armed with weapons other than missiles,

including guns. Even so, aggregate numbers of VLS cells are sometimes used as a shorthand for

measuring a navy’s total missile capacity.40

Selected Elements of China’s Naval Modernization Effort

Below are brief overviews of selected elements of China’s naval modernization effort.

Anti-Ship Missiles

Anti-Ship Ballistic Missiles (ASBMs)

China has fielded two types of land-based ballistic missiles with a capability of hitting ships at

sea at extended ranges—the DF-21D (Figure 7), a road-mobile anti-ship ballistic missile

(ASBM) with a range of more than 1,500 kilometers (i.e., more than 810 nautical miles),41 and

41 2024 DOD CMSD, p. 65.

Congressional Research Service

17

China Naval Modernization: Implications for U.S. Navy Capabilities

the DF-26 (Figure 8), a road-mobile, multi-role intermediate range ballistic missile (IRBM) with

a maximum range of 3,000 kilometers to 4,000 kilometers42 (i.e., about 1,620 nautical miles to

2,160 nautical miles). DOD states that “the multi-role DF-26 is designed to rapidly swap

conventional and nuclear warheads and is capable of conducting precision land-attack and antiship strikes in the Western Pacific, the Indian Ocean, and the SCS [South China Sea] from

mainland China.”43

Figure 7. DF-21D Anti-Ship Ballistic Missile (ASBM)

Missile (ASBM)—Officially Revealed at 3 September Parade—Complete Open Source Research Compendium,”

AndrewErickson.com, September 10, 2015, accessed August 28, 2019.

Observers have expressed strong concerns about China’s ASBMs, because such missiles, in

combination with broad-area maritime surveillance and targeting systems, would permit China to

attack aircraft carriers, other U.S. Navy ships, or ships of allied or partner navies operating in the

Western Pacific.44 Prior to the advent of these weapons, the U.S. Navy had not previously faced a

threat from highly accurate ballistic missiles capable of hitting moving ships at sea. For this

reason, some observers have referred to ASBMs as a “game-changing” weapon.

China reportedly is developing hypersonic glide vehicles that, if incorporated into PLA ASBMs,

could make PLA ASBMs more difficult to intercept.45 DOD states:

In April 2022, the PRC had reportedly developed a new type of ASBM, possibly designated

the YJ-21, small enough to fit into a surface combatant’s VLS cell and tested-fired from a

RENHAI [i.e., Type 055 cruiser or large destroyer]….

42 2024 DOD CMSD, p. 64. A map on page 67 of the report shows the DF-26 with a range of 4,000 kilometers.

43 2024 DOD CMSD, p. 65. The report similarly states on page 89: “The DF-26 intermediate range ballistic missile is a

capable of ranging Guam and is capable of conducting nuclear, precision conventional, and maritime attacks.”

China Naval Modernization: Implications for U.S. Navy Capabilities

In April 2019, the PLAN revealed during its 70th anniversary celebration that its new

guided-missile cruiser [i.e., the Renhai or Type 055] can employ long-range, land-attack

cruise missiles and, in 2022, launched the YJ-21 hypersonic missile designed to defeat

aircraft carriers.46

An August 9, 2024, press report states

Through a series of images and videos that went viral via Open Source Intelligence

(OSINT) sources, the latest test launches of the new YJ-21 hypersonic anti-ship missile

from a Type 055 destroyer of the People’s Liberation Army Navy (PLAN) have come to

light….

The YJ-21 is one of the most advanced hypersonic anti-ship missiles in service at the

People’s Liberation Army Navy, with an operational range of approximately 1,500

kilometers [about 810 nm] and cruising speeds of Mach 6, reaching terminal speeds of

Mach 10.

Although many details about the missile remain classified, various sources speculate that

the missile is an adapted version for launch from surface ships, based on the CM-401

missile, but with substantial improvements in speed and range. Furthermore, as various

reports suggest, there are versions designed to be launched from H-6N bombers in service

with the People’s Liberation Army Air Force.47

A February 2, 2023, press report states

For the first time, the PLA has officially revealed the performance of its advanced antiship hypersonic missile, sending a warning to the US amid high tensions in the Taiwan

Strait, Chinese analysts said.

China’s YJ-21, or Eagle Strike-21, has a terminal speed of Mach 10, cannot be intercepted

by any anti-missile weapons system in the world and can launch lethal strikes towards

enemy ships, according to an article posted by the official Weibo account of the People’s

Liberation Army Strategic Support Force on Monday [January 30]....

The article declares that the missile travels six times the speed of sound all the way, and

has a terminal speed of 10 times the speed of sound, meaning a speed of 3,400 metres per

second (11,155 feet per second) when it hits the target.

“Such a terminal speed cannot be intercepted by any anti-missile weapon system at this

stage. Even if it is dropped directly at this terrifying speed [hitting the target] without an

explosion it will cause a fatal strike to the enemy ship,” the article stated.

The debut of its export variant, the YJ-21E, at last year’s Airshow China “shows that the

domestic version of the Eagle Strike-21 ship-borne hypersonic missile is no longer the

navy’s most advanced ship-borne hypersonic missile, and more advanced ship-borne

hypersonic missiles are likely to have appeared,” it said.

The article was first published on the website of China Science Communication,

Guangming Online last year, but it was reposted by an official PLA account for the first

time, a development experts described as a clear message for the US.48

Anti-Ship Cruise Missiles (ASCMs)

Although China’s ASCMs do not always receive as much press attention as China’s ASBMs,

observers are nevertheless concerned about them. As discussed later in this report, the relatively

long ranges of certain PLA ASCMs have led to concerns among some observers that the U.S.

Navy is not moving quickly enough to arm U.S. Navy surface ships with similarly ranged

ASCMs.

China’s anti-ship cruise missiles (ASCMs) (see Figure 9, Figure 10, and Figure 11 for examples

of reported images) include both Russian- and PRC-made designs, including some advanced and

highly capable ones, such as the PRC-made YJ-18.49 Press reports in April 2019 and December

2021 stated that China might be developing a YJ-18 launcher that can be packaged inside a

standard commercial shipping container, for the potential purpose of surreptitiously deploying

YJ-18s on merchant ships (Figure 12),50 a capability that, if implemented, could violate the law

of naval warfare.51 DOD states, “It is possible the PRC is developing a launcher that can fit inside

China Naval Modernization: Implications for U.S. Navy Capabilities

Submarines

Overview

China has been steadily modernizing its submarine force, and most of its submarines are now

built to relatively modern PRC and Russian designs.53 Qualitatively, China’s newest submarines

might not be as capable as Russia’s newest submarines,54 but compared to China’s earlier

submarines, which were built to antiquated designs, its newer submarines are much more

capable.55 An August 2023 Naval War College Report on China’s submarines states

After nearly 50 years since the first Type 091 SSN was commissioned, China is finally on

the verge of producing world-class nuclear-powered submarines. This report argues that

the propulsion, quieting, sensors, and weapons capabilities of the Type 095 SSGN could

approach Russia’s Improved Akula I class SSN. The Type 095 will likely be equipped with

a pump jet propulsor, a freefloating horizontal raft, a hybrid propulsion system, and 12-18

vertical launch system tubes able to accommodate anti-ship and land-attack cruise missiles.

China’s newest SSBN, the Type 096, will likewise see significant improvements over its

predecessor, with the potential to compare favorably to Russia’s Dolgorukiy class SSBN

in the areas of propulsion, sensors, and weapons, but more like the Improved Akula I in

terms of quieting. If this analysis is correct, the introduction of the Type 095 and Type 096

would have profound implications for U.S. undersea security.56

A September 2023 Naval War College report on China’s submarine industrial base states

In recent years, China’s naval industries have made tremendous progress supporting the

modernization of the People’s Liberation Army Navy (PLAN) submarine force, both

through robust commitment to research and development (R&D) and the upgrading of

production infrastructure at the country’s three submarine shipyards…. Nevertheless,

China’s submarine industrial base continues to suffer from surprising weaknesses in

propulsion (from marine diesels to fuel cells) and submarine quieting. Closer ties with

Russia could provide opportunities for China to overcome these enduring technological

limitations by exploiting political and economic levers to gain access to Russia’s remaining

undersea technology secrets.57

Schwartz, The Changing Nature and Implications of Russian Military Transfers to China, Center for Strategic and

China Naval Modernization: Implications for U.S. Navy Capabilities

Types and Numbers

Most of China’s submarines are non-nuclear-powered attack submarines (SSs). China also

operates a small number of nuclear-powered attack submarines (SSNs) and a small number of

nuclear-powered ballistic missile submarines (SSBNs). The number of SSNs and SSBNs may

grow in coming years, but the force will likely continue for some time to consist mostly of SSs.

DOD states that China’s navy “has highly prioritized modernizing its submarine force but its

force structure continues to grow modestly as it matures its force, integrates new technologies,

and expands its shipyards. The PLAN operates six nuclear-powered ballistic missile submarines

(SSBN), six nuclear-powered attack submarines (SSN), and 48 diesel-powered/air-independent

powered attack submarines (SS). Despite the ongoing retirement of older hulls, the PLAN’s

submarine force is expected to grow to 65 units by 2025 and 80 units by 2035 due to an

expansion of submarine construction capacity.”58

ONI states that “China’s submarine force continues to grow at a low rate, though with

substantially more-capable submarines replacing older units. Current expansion at submarine

production yards could allow higher future production numbers.” ONI projects that China’s

submarine force will grow from a total of 66 boats (4 SSBNs, 7 SSNs, and 55 SSs) in 2020 to 76

boats (8 SSBNs, 13 SSNs, and 55 SSs) in 2030.59 A November 27, 2022, press report states “The

dry-docks at China’s nuclear submarine facility at Huludao, Liaoning province, show increased

activity. New construction halls are primed. Another dry dock is ready to go. International

analysts point to this as evidence Beijing is gearing up for the mass production of a new

generation of nuclear-powered attack and ballistic missile submarines.”60

China’s newest series-built SS design is the Yuan-class (Type 039) SS (Figure 13), its newest

SSN class is the Shang-class (Type 093) SSN (Figure 14), and its newest SSBN class is the Jin

(Type 094) class SSBN (Figure 15). DOD states

The PRC continues to increase its inventory of conventional submarines capable of firing

advanced ASCMs. Between the mid-1990s and mid-2000s, the PLAN purchased 12

Russian-built KILO class SS units, eight of which can launch ASCMs. PRC shipyards have

delivered 13 SONG class SS units (Type 039) and 21 YUAN class diesel-electric airindependent propulsion attack submarines (SSP) (Type 039A/B). The PRC is expected to

produce 25 or more YUAN class submarines by 2025. In late 2021, the PLAN retired the

first two KILO class submarines (both non-ASCM capable) purchased from Russia in the

1990s.61

DOD states further that

Over the past 15 years, the PLAN has constructed 12 nuclear-powered submarines—two

SHANG I class SSNs (Type 093), four SHANG II class SSNs (Type 093A), and six JIN

class SSBNs (Type 094). Equipped with the CSS-N-14 (JL-2) submarine-launched ballistic

missile (SLBM) (3,900 nm) or the CSS-N-20 (JL-3) SLBM (5,400 nm), the PLAN’s six

operational JIN class SSBNs represent the PRC’s first credible sea-based nuclear deterrent.

Each JIN class SSBN can carry up to 12 missiles. In 2019, Beijing displayed these missiles

at the PRC’s 70th founding anniversary parade. The PRC’s next-generation Type 096

SSBN will reportedly be armed with follow-on longer range SLBM. The Type 096 will

likely begin construction soon. Considering the projected 30-plus-year service life of the

platforms [i.e., submarines], the PRC will operate its JIN and Type 096 SSBN fleets

concurrently in the 2030s. This would align with Xi’s 2018 directive for the SSBN force

to achieve “stronger growth.”

The PRC launched four SHANG III class (Type 093B) guided-missile nuclear-powered

attack submarines (SSGN) between May 2022 and January 2023 and could have three hulls

of this class operational by 2025. This new SHANG class variant enhances the PLAN’s

anti-surface warfare capability and could provide a clandestine land-attack option if

equipped with LACMs. The PLAN is improving its anti-submarine warfare (ASW)

capabilities through the development of its surface combatants and special mission aircraft

but continues to lack a robust deep-water ASW capability.62

China Naval Modernization: Implications for U.S. Navy Capabilities

China’s increased focus on nuclear-powered submarines is aimed at boosting long-distance

naval combat and deterrence power amid growing risks of high-seas confrontation with the

US, according to military analysts.

The People’s Liberation Army has for the first time publicly acknowledged a strategic shift

away from conventional submarines, as Beijing pushes to build a modernised military by

2027.

“The current development of China’s submarine fleet is dual-capable, both nuclearpowered and conventional, with a focus on nuclear capabilities,” Wen Xuexing, a member

of a PLA Navy submarine unit, told state broadcaster CCTV.63

Submarine Weapons

China’s submarines are armed with one or more of the following: ASCMs, wire-guided and

wake-homing torpedoes, and mines. Wake-homing torpedoes can be very difficult for surface

ships to decoy. China reportedly is also developing a capability for submarines to deploy

drones.64 DOD states that each Jin-class SSBN is equipped to carry up to 12 JL-2 or JL-3 nucleararmed submarine-launched ballistic missiles (SLBMs).65 The JL-3 is a new SLBM with a range

longer than that of the JL-2. A May 2, 2021, press report stated that China’s latest Jin-class SSBN

is armed with JL-3s.66

Aircraft Carriers

Overview

China’s first aircraft carrier, Liaoning (Type 001), entered service in 2012. China’s second aircraft

carrier (and its first fully indigenously built carrier), Shandong (Type 002), entered service in

2019. China’s third carrier, Fujian (Type 003), reportedly began conducting sea trials in 2024.

China’s fourth carrier reportedly has begun construction.

Liaoning and Shandong are conventionally powered and launch fixed-wing aircraft using an

upward-sloping “ski ramp” at the ship’s bow. Compared with Liaoning and Shandong, U.S. Navy

aircraft carriers are larger, nuclear powered (giving them greater cruising endurance than a

China Morning Post, January 22 (updated January 23), 2025.

65 2024 DOD CMSD, pp. 56, 104. DOD estimates the range of the JL-2 at 3,900 nautical miles (2024 DOD CMSD, p.

53). Such a range could permit Jin-class SSBNs to attack targets in Alaska (except the Alaskan panhandle) from

protected bastions close to China, targets in Hawaii (as well as targets in Alaska, except the Alaskan panhandle) from

locations south of Japan, targets in the western half of the 48 contiguous states (as well as Hawaii and Alaska) from

mid-ocean locations west of Hawaii, or targets in all 50 states from mid-ocean locations east of Hawaii. DOD states

that

With a range of approximately 3,900 nm, a JIN equipped with the JL-2 would have to operate in

the mid-Pacific Ocean to threaten targets in the western half of the continental United States

(CONUS) (as well as Hawaii and Alaska) or east of Hawaii to threaten targets on the East Coast of

the United States. PRC sources claim the JL-3 has a range of over 5,400 nm, which would allow a

JIN armed with this missile to target portions of CONUS from PRC littoral waters.

(2024 DOD CMSD, p. 56.)

66 Minnie Chan, “China’s New Nuclear Submarine Missiles Expand Range in US: Analysts,” South China Morning

Post, May 2, 2021. The article states that the JL-3 has a “range [of] over 10,000km (6,200 miles), a source close to the

[PLA] navy said.” Such a range could permit Jin-class SSBNs to attack larger portions of the United States from the

locations described in the previous footnote.

conventionally powered ship), able to embark and operate a larger number of aircraft, and launch

fixed-wing aircraft using catapults, which can give those aircraft a range/payload capability

greater than that of aircraft launched with a ski ramp. Fujian is conventionally powered, closer in

size and flight deck configuration to U.S. Navy aircraft carriers,67 and equipped with catapults

rather than a ski ramp for launching aircraft.

Observers have speculated that China may eventually field a force of four to six (or possibly more

than six) aircraft carriers. Observers expect that it will be some time before China masters carrierbased aircraft operations on a substantial scale.68

Although aircraft carriers might have some value for China in Taiwan-related conflict scenarios,

they are not considered critical for PLA operations in such scenarios, because Taiwan is within

range of land-based PLA aircraft. Consequently, most observers believe that China is acquiring

carriers primarily for their value in other kinds of operations, and to demonstrate China’s status as

a leading regional power and major world power. PLA aircraft carriers could be used for powerprojection operations, particularly in scenarios that do not involve opposing U.S. forces, and to

impress or intimidate foreign observers.69 In a combat situation involving opposing U.S. naval

and air forces, PLA aircraft carriers would be highly vulnerable to attack by U.S. ships and

aircraft, but conducting such attacks could divert U.S. ships and aircraft from performing other

missions. PLA aircraft carriers could also be used for humanitarian assistance and disaster relief

(HA/DR) operations, maritime security operations (such as antipiracy operations), and

noncombatant evacuation operations (NEOs).

Liaoning (Type 001)

Liaoning (Figure 16) is a refurbished ex-Ukrainian aircraft carrier that China purchased from

Ukraine in 1998 as an unfinished ship.70 It has an estimated full load displacement of about

60,000 tons, and reportedly can accommodate an air wing of 30 or more fixed-wing airplanes and

helicopters, including 24 fighters. China has used Liaoning in part for pilot training. In May 2018,

China reportedly announced that the aircraft carrier group formed around Liaoning had reached

initial operational capability (IOC),71 although that term might not mean the same as it does when

used by DOD in connection with U.S. weapon systems.

China Naval Modernization: Implications for U.S. Navy Capabilities

Shandong (Type 002)

Shandong (Figure 17) is a modified version of the Liaoning design that incorporates some design

improvements, including features that reportedly will permit it to embark and operate a larger air

wing of 40 aircraft that includes 36 fighters.72 Its displacement is estimated at about 66,000 tons.

Fujian (Type 003)

Fujian (and Figure 18, Figure 19, and Figure 20) was launched (i.e., put into the water for the

final stages of its construction) on June 17, 2022,73 and reportedly began conducting sea trials in

early May 2024.74 Some observers believe it could be years before the ship begins making regular

deployments.75 The ship has an estimated full load displacement of about 80,000 tons and is

equipped, as observers had expected, with electromagnetic catapults rather than a ski ramp, which

will improve the range/payload capability of the fixed-wing aircraft that it operates.76

China’s Fourth Carrier

China reportedly is building a fourth aircraft carrier.77 The ship’s design, including its estimated

displacement and whether it will be nuclear-powered or conventionally powered, had not been

announced as of April 2025.

Reported New Dedicated Drone Carrier

China reportedly is building a new dedicated drone carrier (i.e., a carrier whose embarked air

wing would consist entirely of unmanned aerial vehicles [UAVs]) (Figure 21).78

Carrier-Based Aircraft80

China’s primary carrier-based fighter aircraft is the J-15, or Flying Shark (Figure 22), an aircraft

derived from the Russian Su-33 Flanker aircraft design that can operate from carriers equipped

with a ski ramp rather than catapults, but that some observers have critiqued for its range/payload

limitations in operations from carriers equipped with ski ramps rather than catapults.81 China has

developed an upgraded, catapult-capable version of the J-15 that could have improved

range/payload when operated from a catapult-equipped carrier.82

China Naval Modernization: Implications for U.S. Navy Capabilities

Surface Combatants

Overview

China since the early 1990s has put into service numerous new classes of indigenously built

surface combatants, including a highly capable new cruiser (also referred to as a large destroyer),

several successive classes of increasingly modern and capable destroyers and frigates, a new class

of corvettes (i.e., light frigates), and a new class of missile-armed patrol craft. These new classes

of surface combatants demonstrate a significant modernization of PLA Navy surface combatant

technology.

DOD states that China’s navy “remains engaged in a robust shipbuilding program for surface

combatants. As of early 2024, the PLAN is building a new batch of CG [cruisers], DDG

[destroyers], and two different classes of guided-missile frigates, including a larger, more capable

variant: designated JIANGKAI III ([Type] 054B). These assets will significantly upgrade the

PLAN’s air defense, anti-ship, and anti-submarine capabilities and will be critical as the PLAN

expands its operations beyond the range of the PLA’s shore-based air defense systems.”86 DIA

states that “the era of past designs has given way to production of modern multimission destroyer,

frigate, and corvette classes as China’s technological advancement in naval design has begun to

approach a level commensurate with, and in some cases exceeding, that of other modern

navies.”87 China has also upgraded some of its older surface combatants with new weapons and

other equipment.88

Type 055 Cruiser/Large Destroyer

China is building a new class of cruiser (also referred to as a large destroyer), called the Renhaiclass or Type 055 (Figure 24 and Figure 25) that reportedly displaces between 12,000 and

13,000 tons.89 A March 7, 2021, press report by a PRC media outlet states that the ship displaces

more than 12,000 tons.90 By way of comparison, the U.S. Navy’s Ticonderoga (CG-47) class

cruisers and Arleigh Burke (DDG-51) class destroyers (aka the U.S. Navy’s Aegis cruisers and

destroyers) displace about 10,100 tons and 9,700 tons, respectively, while the U.S. Navy’s three

Zumwalt (DDG-1000) class destroyers displace about 15,700 tons. ONI states that Type 055 ships

are being built by two shipyards.91 The first Type 055 ship was reportedly commissioned into

86 2024 DOD CMSD, p. 53.

87 2019 DIA CMP, p. 70.

tons.” (Liu Xuanzun, “Chinese PLA’s Two Newly Commissioned Large Destroyers ‘Ready for Combat’ with Latest

Type 056 Corvette

China has built a new class of corvettes (i.e., a light frigates, or FFLs) called Jiangdao class or

Type 056 ships (Figure 29) that reportedly displace 1,300 tons to 1,500 tons.98 Type 056 ships

were built at a high annual rate in four shipyards—the first was commissioned in 2013, and the

72nd and final ship of the type was reportedly commissioned in early 2021, implying an average

commisisoning rate of about eight ships per year. DOD states that China’s navy “commissioned

the 72nd JIANGDAO in February 2021, completing the production run. The PLAN subsequently

transferred the early flight Type 056 variants, likely 22 ships total, to the CCG [China Coast

committee’s permission. For a press article discussing the potential features of China’s next frigate design beyond the

contributing to ASW operations.”99 As shown in Table 1, the rapid growth in the number of Type

Type 071 Amphibious Ship

China’s new Yuzhao or Type 071 amphibious ships (Figure 31) have an estimated displacement

of more than 19,855 tons,101 compared to about 25,900 tons for the U.S. Navy’s new San Antonio

(LPD-17) class amphibious ships. A May 6, 2021, press report states that the eighth Type 071 ship

“recently made its first publicly known maritime exercise appearance.”102

Ships 2017-2018, p. 156, does not provide a full load displacement for the Type 071 class design. Instead, it provides a

standard displacement of 19,855 tons. Full load displacement is larger than standard displacement, so the full load

displacement of the Type 071 design is more than 19,855 tons.

Type 075 Amphibious Assault Ship

In April 2021, China commissioned into service the first of a new type of amphibious assault

displacement of about 36,000 tons, compared to 41,000 to 45,000 tons for U.S. Navy LHA/LHDtype amphibious assault ships.104 In March 2022, it was reported that the first Type 075 ship had

achieved initial operational capability (IOC),105 although that term might not mean the same as it

does when used by DOD in connection with U.S. weapon systems. The second Type 075 ship

reportedly was commissioned into service in late December 2021.106 The third was reportedly

commissioned on or perhaps a few days prior to October 1, 2022.107 The fourth reportedly

Amphibious Ship Roles and Missions

Although larger amphibious ships such as the Type 071, Type 075, and Type 076 would be of

value for conducting amphibious landings in Taiwan-related conflict scenarios, some observers

believe that China is building such ships in part for their value in conducting other operations,

such as operations for asserting and defending China’s claims in the South and East China Seas,

humanitarian assistance/disaster relief (HA/DR) operations, maritime security operations (such as

antipiracy operations), and noncombatant evacuation operations (NEOs). Politically, amphibious

ships can also be used for naval diplomacy (i.e., port calls and engagement activities) and for

impressing or intimidating foreign observers.

Potential Use of Commercial Ships

Whether and when China will become capable of conducting a large-scale amphibious invasion

of Taiwan is an ongoing matter of debate and discussion.111 In assessing China’s capacity for

conducting a large-scale amphibious invasion of Taiwan, some observers have focused on China’s

potential for using civilian ferries and other commercial ships to augment the transport and

landing capacity of China’s amphibious ships. Reported PLA exercises indicate that China is

exploring and testing this concept.112

Operations Away from Home Waters

Ship Operations

Although China’s navy operates primarily in China’s home waters, PLA Navy ships are

conducting increasing numbers of operations away from China’s home waters, including the

broader waters of the Western Pacific, the Indian Ocean, and the waters surrounding Europe,

including the Mediterranean Sea and the Baltic Sea. A November 23, 2019, DOD news report

quoted Admiral Philip Davidson, the commander of the U.S. Indo-Pacific Command, as stating

that China’s navy had conducted more global naval deployments in the previous 30 months than

it had in the previous 30 years.113

DOD states that “the PLAN’s ability to perform missions beyond the FIC [first island chain] is

modest but growing as it gains more experience operating in distant waters and acquires larger

and more advanced platforms. The PRC’s experience in extended range operations primarily

comes from extended task group deployments and its ongoing counterpiracy mission in the Gulf

of Aden.”114 China has been conducting antipiracy operations in the Gulf of Aden since December

2008 via a succession of more than 45 rotationally deployed naval escort task forces.115 China’s

long-distance naval deployments have also been for making diplomatic port calls and conducting

training exercises.

China Naval Modernization: Implications for U.S. Navy Capabilities

Current or Potential Bases Outside China

China’s distant naval operations are supported in part by China’s military base in Djibouti,

which is located where the Gulf of Aden meets the Red Sea. China officially opened the base in

August 2017 as its first overseas military base.116

Some observers expect that China in coming years will seek to establish a global network of

locations in various parts of the world for refueling and resupplying PLA Navy ships conducting

distant naval operations.117 DOD states that

Beyond its base in Djibouti, the PRC is very likely considering and planning for additional

military logistics facilities to support naval, air, and ground forces projection.

The PRC has likely considered Burma, Thailand, Indonesia, Pakistan, Sri Lanka, United

Arab Emirates, Kenya, Equatorial Guinea, Seychelles, Tanzania, Angola, Nigeria,

Namibia, Mozambique, Bangladesh, Papua New Guinea, the Solomon Islands, and

Tajikistan. The PRC has probably already made overtures to Gabon, Equatorial Guinea,

Namibia, Vanuatu, and the Solomon Islands. The PLA is probably most interested in

military access along the SLOCs from the PRC to the Strait of Hormuz and Africa.118

Observers are following developments at Cambodia’s Ream naval base, which fronts onto the

Gulf of Thailand.119 DOD states, “In June 2022, a PRC official confirmed that the PLA would

A security agreement between China and the Solomon Islands that was announced by the

Solomon Islands in April 2022 has led some observers to express concern that the agreement

could eventually lead to, among other things, the establishment of a PRC naval base in that

country.121 The Prime Minister of the Solomon Islands reportedly ruled out that possibility, stating

that it would “put our country and our people as targets for potential military strikes.”122

In December 2021, it was reported that China may be seeking to establish a military (including

naval) base at a port in Equatorial Guinea, a country located on the Atlantic coast of Africa—a

location that could enhance China’s ability to conduct naval operations in the Atlantic.123

China Naval Modernization: Implications for U.S. Navy Capabilities

U.S. Navy Response

Overview

The U.S. Navy has taken a number of actions to counter China’s naval modernization effort.

Among other things, the U.S. Navy has

•

•

•

•

•

•

•

shifted a greater percentage of its fleet to the Pacific;126

assigned its most-capable new ships and aircraft to the Pacific;

maintained or increased general presence operations, training and developmental

exercises, and engagement and cooperation with allied and other navies in the

Indo-Pacific;

increased the planned future size of the Navy;

initiated, increased, or accelerated numerous programs for developing new

military technologies and acquiring new ships, aircraft, unmanned vehicles, and

weapons;

developed new operational concepts (i.e., new ways to employ Navy and Marine

Corps forces) for countering PLA maritime A2/AD forces; and

signaled that the Navy in coming years will shift to a more distributed fleet

architecture that will feature a substantially greater use of unmanned vehicles.

Some of the above items are discussed in more detail below.

Planned Size of Navy

As discussed in greater detail in another CRS report,127 the Navy’s preferred force-level goal calls

for achieving and maintaining a fleet of 381 battle force ships, compared to the Navy’s 296 battle

force ships as of September 30, 2024. Under the Navy’s FY2025 30-year (FY2025-FY2054)

shipbuilding plan, the U.S. Navy would grow to more than 300 ships in FY2032 and reach a total

of more than 381 ships in FY2042.

126 Efforts in this regard began at least as far back as 2006: The final report on the 2006 Quadrennial Defense Review

(QDR) directed the Navy “to adjust its force posture and basing to provide at least six operationally available and

sustainable carriers and 60% of its submarines in the Pacific to support engagement, presence and deterrence.” (U.S.

Department of Defense, Quadrennial Defense Review Report. Washington, 2006. February 6, 2006, p. 47.) Subsequent

to this directive, the Navy announced an intention to increase to 60% (from a starting point of about 55%) the

percentage of the fleet as a whole that is assigned to the Pacific. An October 13, 2021, press report stated, “US Naval

Chief of Operations, Admiral Michael Gilday, on Tuesday kicked off his 5-day visit to India by meeting his Indian

counterpart Admiral Karambir Singh, Chief of Defence Staff General Bipin Rawat and other senior government

officials.... Asked about what the US intends to do to counter China’s aggressive modernisation of its Navy, Gilday

said they will not try to outspend it, but partners like India in the region will be the key to ensure that the Indian Ocean

Region (IOR) is stable. Given the importance of the region, 60 per cent of US Navy’s forces are now in the IndoPacific, he said.” (Krishn Kaushik, “60% Navy Forces in Indo-Pacific Region Now: US Navy Chief,” Indian Express,

October 13, 2021.)

China Naval Modernization: Implications for U.S. Navy Capabilities

Highly Capable Ships, Aircraft, Weapons, and Other Systems

Many of the Navy’s programs for acquiring highly capable ships, aircraft, weapons, and other

systems can be viewed as intended, at least in part, at improving the U.S. Navy’s ability to

counter PLA maritime A2/AD capabilities. Examples include the following:

•

•

•

•

•

•

•

•

•

•

•

Virginia-class nuclear-powered attack submarines (SSNs);128

the Navy’s envisaged next-generation SSN, called the SSN(X);129

Arleigh Burke (DDG-51) class guided missile destroyers (DDGs);132

the Navy’s envisaged next-generation DDG, called the DDG(X);133

Constellation (FFG-62) class frigates;134

new anti-ship weapons, such as the Long-Range Anti-Ship Missile (LRASM);135

hypersonic weapons, including the ship-launched Conventional Prompt Strike

(CPS) weapon and the Hypersonic Air-Launched OASuW (HALO) weapon, also

known as OASuW Increment 2;136

an ability to do at-sea reloading of Vertical Launch System (VLS) missile tubes

on Navy surface combatants, so that VLS-equuipped Navy surface combatants

engaged in combat operations do not need to withdraw to a distant port to be

reloaded;137

shipboard high-energy lasers;138

undersea surveillance systems for detecting and tracking adversary

submarines.140

New Distributed Maritime Operations (DMO) Operating Concept

As discussed in another CRS report,141 the Department of the Navy (which includes the Navy and

Marine Corps) is implementing a new operating concept called Distributed Maritime Operations

(DMO) for using U.S. naval (i.e., Navy and Marine Corps) forces in combat operations against an

adversary, particularly China, that has substantial capabilities for detecting and attacking U.S.

Navy surface ships with anti-ship missiles and other weapons. Key features of DMO appear to

include the following:

•

•

•

•

Dispersing Navy units over a larger area within the theater of operations, so as to

make it harder for an adversary to detect and target Navy units, while still

permitting Navy units to support one another and concentrate their fires on

adversary targets.

Spreading the Navy’s sensors and weapons across a wider array of ships and

aircraft, so as to reduce the fraction of the Navy’s sensors and weapons that

would be lost due to the destruction of any one Navy ship or aircraft (i.e., avoid

“putting too many eggs into one basket”).

Making greater use of longer-ranged weapons, unmanned vessels, and unmanned

aircraft in support of the previous two points.

Using resilient communication links and networking technologies to knit the

resulting widely dispersed force of manned and unmanned ships and aircraft into

a coordinated battle force that can withstand and adapt to enemy attacks on Navy

communications and networks.

Some examples of Navy acquisition programs that appear associated with DMO include the

following:

•

•

Programs for acquiring longer-ranged weapons, such as the Maritime Strike

Tomahawk (a new anti-ship variant of the Tomahawk cruise missile) and the

previously mentioned Long-Range Anti-Ship Missile (LRASM).

The Large Unmanned Surface Vessel (LUSV), which is to be equipped with a

Vertical Launch System (VLS) for storing and firing anti-ship missiles and other

weapons. LUSVs are intended to act as adjunct missile magazines for manned

Navy surface combatants.142

War Zone, November 8, 2023; Brett Tingley and Tyler Rogoway, “Navy’s New Shipboard Electronic Warfare System

The Medium Unmanned Surface Vessel (MUSV), which is to be equipped with

radars or other sensors. MUSVs are intended to help form a distributed sensor

network for supporting Navy operations.143

The light replenishment oiler (TAOL) shipbuilding program for building a new

class of smaller oilers. TAOLs are intended to enhance the Navy’s ability to

provide fuel and supplies to Navy ships that are operating in a more distributed

manner across a wider sea area.144

The Medium Landing Ship (LSM) program for building a class of smaller

amphibious ships. The LSM program is central to implementing a Marine Corps

operating concept associated with DMO that is called Expeditionary Advanced

Base Operations (EABO).145

Cooperation with Naval Forces of Allies and Other Countries

In General

U.S. Navy efforts to increase cooperation with naval forces from allies such as Japan and

Australia and other countries such India, including exercises and other forms of engagement,

appear aimed not only at improving interoperability between U.S. and allied naval forces, but also

at expanding existing bilateral forms of naval cooperation (e.g., U.S.-Japan, U.S.-Australia,

U.S.-India) into trilateral (e.g., U.S.-Japan-Australia, U.S.-Australia-India) or quadrilateral (e.g.,

U.S.-Japan-Australia-India) forms that could enhance the ability of the United States and its allies

in the Indo-Pacific region to balance against China’s growing military capabilities and deter

potential assertive actions by China.146

AUKUS Security Agreement

The Australia-United Kingdom-United States (AUKUS) trilateral security partnership announced

in September 2021 includes a major initiative (called Pillar 1) to homeport U.S. and UK nuclearpowered attack submarines (SSNs) in Australia and establish an eight-boat Australian SSN

force,147 and another major initiative (called Pillar 2) for the three countries to cooperatively

pursue advanced military capabilities, including undersea capabilities other than SSNs (such as

unmanned underwater vehicles and undersea weapons); quantum technologies; artificial

intelligence and autonomy; advanced cyber capabilities; hypersonic and counter-hypersonic

capabilities; and electronic warfare.148
