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

weaknesses.24 Although China’s navy has limitations and weaknesses, it may
nevertheless be sufficient for performing missions of interest to China’s leaders.

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:

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

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

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

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]….

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.”

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

21, 2022, press report (Xavier Vavasseur, “Five Type 052D Destroyers Under Construction In China,” Naval News,
August 21, 2022) referred to a photograph of five Type 05D ships under construction at a shipyard at Dalian, China.
The article stated, “Contacted by Naval News, two Chinese military observers confirmed that there are currently 25
destroyers of the class (13 Type 052D and 12 Type 052DL) currently in service with the PLAN. They will soon be
joined by the five under construction at Dalian and (at least) one more being built at the Jiangnan Changxing
Shipbuilding and Heavy Industry Corporation (the other Chinese shipyard building large surface combatants, located
North East of Shanghai).”

Type 054 Frigate
China since the early 1990s has also put into service multiple new classes of indigenously built
frigates, the most recent of which is the Jiangkai II (Type 054A) class (Figure 27), which
displaces about 4,000 tons. ONI stated in February 2020 that 30 Type 054As entered service
between 2008 and 2019.95 Construction of Type 054 frigates reportedly has shifted to improved

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
Type 054A, see Rick Joe, “What Will the Chinese Navy’s Next Frigate Look Like?” Diplomat, May 15, 2020.
