“China Naval Modernization: Implications for U.S. Navy Capabilities”—USG/N Info on PLAN Ships & Projections of #s Lead thru 2040—O’Rourke’s Latest CRS Report

As part of Ronald O’Rourke’s continuous incremental improvements, this # 26X (!) edition of his report on PRC naval modernization incorporates numbers provided by the U.S. Navy. Given the authoritative analysis supporting these revelations, and the rarity with which they are made publicly available in this manner, they are all worth reading carefully in full!

Bottom line up front: here’s the key table (p. 11):

By 2040, the PLA Navy is thus projected to have the following:

  • Ballistic missile submarines (SSBN): 10 (+6)
  • Nuclear-powered attack submarines (SSN): 16 (+10)
  • Diesel attack submarines (SSK): 46 (-1)
  • Aircraft carriers (CV): 6 (+4)
  • Cruisers and destroyers (CG & DDG): 80 (+39)
  • Frigates and corvettes (FFG & FFL): 140 (+38)
  • Amphibious Assault Ship-type amphibious ships (LHA): 6 (+6)
  • Amphibious Transport Dock-type amphibious ships 14 (LPD): (+7)
  • Tank Landing Ship-type amphibious ships (LST): 15 (-15)
  • TOTAL of above-mentioned types: 333 (+94)

Note from me (Andrew Erickson): The U.S. Navy is duty bound to count PLA Navy ship numbers strictly according to the criteria listed in SECNAVINST 5030.8C (“General Guidance for the Classification of Naval Vessels and Battle Force Ship Counting Procedures”). The resulting battle force numbers calculated for China therefore correspond numerically with those for the U.S. Navy battle force. To be sure, aspects of the analysis and implications can be complex in practice, and O’Rourke offers thoughtful explanations and implications in his frequently-updated report.

Introduction 

Issue for Congress 

This report provides background information and issues for Congress on China’s naval modernization effort 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 Biden 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 Chinese military 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.

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 Chinese 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 that “the PLAN is the largest navy in the world with a battle force of approximately 340 platforms, including major surface combatants, submarines, ocean-going amphibious ships, mine warfare ships, aircraft carriers, and fleet auxiliaries…. This figure does not include approximately 85 patrol combatants and craft that carry anti-ship cruise missiles (ASCM). The PLAN’s overall battle force is expected to grow to 400 ships by 2025 and 440 ships by 2030. Much of this growth will be in major surface combatants.”8 The U.S. Navy, by comparison, included 294 battle force ships at the end of FY2021, and the Navy’s FY2024 budget submission projects that the Navy will include 290 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 and resulting trend lines regarding the relative sizes and capabilities of China’s navy and the U.S. Navy.10

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 military-applicable 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.

  • China’s navy is viewed as posing a major challenge to 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 Chinese 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 that “as of 2021, the PLAN is largely composed of modern multi-role platforms featuring advanced anti-ship, anti-air, and anti-submarine 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 Chinese 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 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 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

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.”24 China also operates a

See also Andrew Scobell, “Xi Jinping’s Worst Nightmare: A Potemkin People’s Liberation Army,” War on the Rocks, May 1, 2023. 

The use of a dual command structure in the crews of larger Chinese 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. See “Leadership: China Cripples Naval Officers,” Strategy Page, July 18, 2020. 

Some observers argue that corruption in China’s shipbuilding companies may be a source of weaknesses in China’s naval modernization effort. See, for example, Zi Yang, “The Invisible Threat to China’s Navy: Corruption,” Diplomat, May 19, 2020. See also Frank Chen, “Ex-PLA Navy Chief in Deep Water Amid War on Graft,” Asia Times, June 26, 2020. 

23 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 in-country, and China no longer relies on Russia or other countries for any significant naval ship systems.” (Source: Unclassified ONI information paper prepared for Senate Armed Services Committee, subject “UPDATED China: 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 also improving its anti-submarine warfare (ASW) capabilities through the development of its surface combatants and special mission aircraft, but it continues to lack a robust deep-water ASW capability. By prioritizing the acquisition of ASW capable surface combatants, acoustic surveillance ships, and fixed and rotary wing ASW capable aircraft, the PLAN is significantly improving its ASW capabilities. However, it will still require several years of training and systems integration for the PLAN to develop a robust offensive deep water ASW capability.

24 DOD states that 

The CCG’s [China Coast Guard’s] rapid expansion and modernization has made it the largest maritime law enforcement fleet in the world. Its newer vessels are larger and more capable than older vessels, allowing them to operate further offshore and remain on station longer. A 2019 academic study published by the U.S. Naval War College estimates the CCG has over 140 regional and oceangoing patrol vessels (of more than 1,000 tons displacement). Some of the vessels are former PLAN vessels, such as corvettes, transferred to the CCG and modified for CCG operations. The newer, larger vessels are equipped with helicopter facilities, high-capacity water cannons, interceptor boats, and guns ranging from 20 to 76 millimeters. In addition, the same academic study indicates the CCG operates more than 120 regional patrol combatants (500 to 999 tons), which can

Numbers of Ships; Comparisons to U.S. Navy

Overview

DOD states that “the PLAN is the largest navy in the world with a battle force of approximately 340 platforms, including major surface combatants, submarines, ocean-going amphibious ships, mine warfare ships, aircraft carriers, and fleet auxiliaries…. This figure does not include approximately 85 patrol combatants and craft that carry anti-ship cruise missiles (ASCM). The PLAN’s overall battle force is expected to grow to 400 ships by 2025 and 440 ships by 2030. Much of this growth will be in major surface combatants.”26 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.”27

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.28 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 Chinese 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.”29

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

Relative U.S. and Chinese naval capabilities are sometimes assessed by showing comparative numbers of U.S. and Chinese ships. Although the total number of ships in a navy (or a navy’s aggregate tonnage) 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 are highly problematic as a means of assessing relative U.S. and Chinese 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 can shed some light on how the relative balance of U.S. and Chinese naval capabilities might be changing over time. 

Three Tables Showing Numbers of Chinese and U.S. Navy Ships 

Table Showing Figures from Annual DOD Reports 

Table 1 shows numbers of certain types of Chinese navy ships—those that might be thought of as the principal combat ships of China’s navy—from 2005 to the present, along with the number of China coast guard ships from 2017 to the present, as presented in DOD’s annual reports on military and security developments involving China. As can be seen in Table 1, every type of Chinese navy ship shown in the table has increased numerically since 2005. 

As can be seen in Table 1, about 61% of the increase since 2005 in the total number of Chinese navy ships shown in the table (a net increase of 83 ships out of a total net increase of 135 ships) resulted from increases in missile-armed fast patrol craft starting in 2009 (a net increase of 33 ships) and corvettes starting in 2014 (50 ships). These are the smallest surface combatants shown in the table. The net 33-ship increase in missile-armed fast patrol craft was due to the construction between 2004 and 2009 of about 60 new Houbei (Type 022) fast attack craft30 and the retirement of about 27 older fast attack craft. The 50-ship increase in corvettes is due to the Jingdao (Type 056) corvette program discussed later in this report. ONI states that “a significant portion of China’s Battle Force consists of the large number of new corvettes and guided-missile frigates recently built for the PLAN.”31 As can also be seen in the table, most of the remaining increase since 2005 in the number of Chinese navy ships shown in the table is accounted for by increases in cruisers and destroyers (21 ships) and amphibious ships (14 ships). 

Table 1 lumps together less capable older Chinese ships with more capable modern Chinese ships. In examining the numbers in the table, it can be helpful to keep in mind that for many of the types of Chinese 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 ships in the U.S. Navy (known technically as the total number of battle force ships), and compares it to the total number of the types of

Chinese ships that are shown in the table.32 The result is an apples-vs.-oranges comparison, because the Chinese figures exclude certain ship types, such as auxiliary and support ships, while the U.S. Navy figure includes auxiliary and support ships but excludes 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 Chinese navies. 

On the basis of the figures in Table 1, it might be said that in 2015, the total number of principal combat ships in China’s navy surpassed the total number of U.S. Navy battle force ships (a figure that includes not only the U.S. Navy’s principal combat ships, but also other U.S. Navy ships, such as 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. 

Table Showing ONI Figures from February 2020 

Table 2 shows comparative numbers of Chinese and U.S. battle force ships (and 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. Battle force ships are the types of ships that count toward the quoted size of the U.S. Navy. For China, the total number of battle force ships shown excludes the missile-armed coastal patrol craft shown in Table 1, but includes auxiliary and support ships that are not shown in Table 1. Compared to Table 1, the figures in Table 2 come closer to providing an apples-to-apples comparison of the two navies’ numbers of ships, although it could be argued that China’s missile-armed coastal patrol craft can be a significant factor for operations within the first island chain. 

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. 

Table Showing U.S. Navy Figures from October 2020 

Table 3 shows numbers of certain types of Chinese navy ships in 2020, and projections of those numbers for 2025, 2030, and 2040, along with the total number of U.S. Navy battle force ships in 2020, and projections of those numbers for 2025, 2030, and 2040. The figures for China’s ships were provided by the Navy at the request of CRS. As with Table 1, the result is an apples-vs.-oranges comparison between the Chinese navy and U.S. Navy totals, because the Chinese total excludes certain ship types, such as auxiliary and support ships, while the U.S. Navy total includes auxiliary and support ships.

Sources: Table prepared by CRS based on 2005-2022 editions of annual DOD report to Congress on military and security developments involving China (known for 2009 and prior editions as the report on China military power), and (for U.S. Navy ships) U.S. Navy data as presented in CRS Report RL32665, Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress, by Ronald O’Rourke. Consistent with the DOD report, which shows data for China for the year prior to the report’s publication date, the U.S. Navy data here shows data for the year prior to the prior to the DOD report’s publication date. For example, the figure of 294 shown for the U.S. Navy for 2022 shows the number of U.S. Navy ships at the end of FY2021. 

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 coastal 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.

Table 2. Numbers of Chinese and U.S. Navy Battle Force Ships, 2000-2030

As shown in Table 3, the U.S. Navy projects that between 2020 and 2040, the total number of Chinese 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). Numbers of ballistic missile submarines and nuclear-powered attack submarines are each projected to more than double between 2020 and 2040, and the total number of diesel attack submarines is projected to remain almost unchanged. The number of large surface combatants is projected to almost double, and the number of small surface combatants is projected to increase by more than one-third. Numbers of larger (LHA- and LPD-type) amphibious ships are projected to increase, and the number of smaller (LST-type) amphibious ships is projected to decline, with the result that the total number of amphibious ships of all kinds is projected to decline slightly.

Selected Elements of China’s Naval Modernization Effort 

This section provides a brief overview of elements of China’s naval modernization effort that have attracted frequent attention from observers. 

Anti-Ship Missiles 

Anti-Ship Ballistic Missiles (ASBMs) 

China is fielding two types of land-based ballistic missiles with a capability of hitting ships at sea at extended ranges—the DF-21D (Figure 1), a road-mobile anti-ship ballistic missile (ASBM) with a range of more than 1,500 kilometers (i.e., more than 910 nautical miles), and the DF-26 (Figure 2), a road-mobile, multi-role intermediate range ballistic missile (IRBM) with a maximum range of about 3,000 kilometers (i.e., about 1,620 nautical miles) that DOD says is “capable of conducting both conventional and nuclear precision strikes against ground targets as well as conventional strikes against naval targets.”33

Until 2020, reported test flights of DF-21s and SDF-26s had not involved attempts to hit moving ships at sea. A November 14, 2020, press report stated that an August 2020 test firing of DF-21 and DF-26 ASBMs into the South China resulted in the missiles successfully hitting a moving target ship south of the Paracel Islands.34 A December 3, 2020, press report stated that Admiral Philip Davidson, the commander of U.S. Indo-Pacific Command, “confirmed, for the first time

from the U.S. government side, that China’s People’s Liberation Army has successfully tested an anti-ship ballistic missile against a moving ship.”35 

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. The U.S. Navy has 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. 

In April 2022, it was reported that China may have developed a new type of ASBM, perhaps designated the YJ-21, that is small enough to fit into the vertical launch tube of a surface combatant, and that China had test fired such a weapon from a Type 055 cruiser (or large destroyer).36 

China reportedly is developing hypersonic glide vehicles that, if incorporated into Chinese ASBMs, could make Chinese ASBMs more difficult to intercept. A February 2, 2023, press report states 

For the first time, the PLA has officially revealed the performance of its advanced anti-ship 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.37

Submarines 

Overview 

China has been steadily modernizing its submarine force, and most of its submarines are now built to relatively modern Chinese and Russian designs.41 Qualitatively, China’s newest submarines might not be as capable as Russia’s newest submarines,42 but compared to China’s earlier submarines, which were built to antiquated designs, its newer submarines are much more capable.43 … …

Appendix A. Comparing U.S. and Chinese Numbers of Ships and Naval Capabilities

This appendix presents some additional discussion of factors involved in comparing U.S. and Chinese numbers of ships and naval capabilities.

U.S. and Chinese naval capabilities are sometimes compared by showing comparative numbers of U.S. and Chinese ships. Although the total number of ships in a navy (or a navy’s aggregate tonnage) 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. One-dimensional comparisons of the total numbers of ships in China’s navy and the U.S. Navy are highly problematic as a means of assessing relative U.S. and Chinese naval capabilities and how those capabilities compare to the missions assigned to those navies, for the following reasons:

  • A fleet’s total number of ships (or its aggregate tonnage) is only a partial metric of its capability. Many factors other than ship numbers (or aggregate tonnage) contribute to naval capability, including types of ships, types and numbers of aircraft, the sophistication of sensors, weapons, C4ISR systems, and networking capabilities, supporting maintenance and logistics capabilities, doctrine and tactics, the quality, education, and training of personnel, and the realism and complexity of exercises.158 In light of this, navies with similar numbers of ships or similar aggregate tonnages can have significantly different capabilities, and navy-to-navy comparisons of numbers of ships or aggregate tonnages can provide a highly inaccurate sense of their relative capabilities. The warfighting capabilities of navies have derived increasingly from the sophistication of their internal electronics and software. This factor can vary greatly from one navy to the next, and often cannot be easily assessed by outside observation. As the importance of internal electronics and software has grown, the idea of comparing the warfighting capabilities of navies principally on the basis of easily observed factors such as ship numbers and tonnages has become increasingly less reliable, and today is highly problematic.
  • Total numbers of ships of a given type (such as submarines or surface combatants) can obscure potentially significant differences in the capabilities of those ships, both between navies and within one country’s navy. Differences in capabilities of ships of a given type can arise from a number of other factors, including sensors, weapons, C4ISR systems, networking capabilities, stealth features, damage-control features, cruising range, maximum speed, and reliability and maintainability (which can affect the amount of time the ship is available for operation).
  • A focus on total ship numbers reinforces the notion that changes in total numbers necessarily translate into corresponding or proportional changes in aggregate capability. For a Navy like China’s, which is modernizing by replacing older, obsolescent ships with more modern and more capable ships, this is not necessarily the case. For example, while China’s attack submarine force has only a modestly larger number of boats now than it had in 2000 or 2005 (see

***

p. 61

  • Table 1 and Table 2), it has considerably more aggregate capability than it did in 2000 or 2005, because the force today includes a much larger percentage of relatively modern designs. 
  • Comparisons of total numbers of ships (or aggregate tonnages) do not take into account the differing global responsibilities and homeporting locations of each fleet. The U.S. Navy has substantial worldwide responsibilities, and a substantial fraction of the U.S. fleet is homeported in the Atlantic. As a consequence, only a certain portion of the U.S. Navy might be available for a crisis or conflict scenario in China’s near-seas region, or could reach that area within a certain amount of time. In contrast, China’s navy has more-limited responsibilities outside China’s near-seas region, and its ships are all homeported along China’s coast at locations that face directly onto China’s near-seas region. In a U.S.-China conflict inside the first island chain, U.S. naval and other forces would be operating at the end of generally long supply lines, while Chinese naval and other forces would be operating at the end of generally short supply lines. 
  • Comparisons of numbers of ships (or aggregate tonnages) do not take into account maritime-relevant military capabilities that countries might have outside their navies, such as land-based anti-ship ballistic missiles (ASBMs), land-based anti-ship cruise missiles (ASCMs), and land-based Air Force aircraft armed with ASCMs or other weapons. Given the significant maritime-relevant non-navy forces present in both the U.S. and Chinese militaries, this is a particularly important consideration in comparing U.S. and Chinese military capabilities for influencing events in the Western Pacific. Although a U.S.-China incident at sea might involve only navy units on both sides, a broader U.S.-China military conflict would more likely be a force-on-force engagement involving multiple branches of each country’s military. 
  • The missions to be performed by one country’s navy can differ greatly from the missions to be performed by another country’s navy. Consequently, navies are better measured against their respective missions than against one another. Although Navy A might have less capability than Navy B, Navy A might nevertheless be better able to perform Navy A’s intended missions than Navy B is to perform Navy B’s intended missions. This is another significant consideration in assessing U.S. and Chinese naval capabilities, because the missions of the two navies are quite different. 

As mentioned earlier, while comparisons of the total numbers of ships in China’s Navy and the U.S. Navy are highly problematic as a means of assessing relative U.S. and Chinese naval capabilities and how those capabilities compare to the missions assigned to those navies, an examination of the trends over time in the relative numbers of ships can shed some light on how the relative balance of U.S. and Chinese naval capabilities might be changing over time. … …

Summary

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 approximately 340 platforms, including major surface combatants, submarines, ocean-going amphibious ships, mine warfare ships, aircraft carriers, and fleet auxiliaries…. This figure does not include approximately 85 patrol combatants and craft that carry anti-ship cruise missiles (ASCM). The… overall battle force [of China’s navy] is expected to grow to 400 ships by 2025 and 440 ships by 2030.” The U.S. Navy, by comparison, included 294 battle force ships at the end of FY2021, and the Navy’s FY2024 budget submission projects that the Navy will include 290 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 and resulting 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; developed new operational concepts for countering Chinese 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. The issue for Congress is whether to approve, reject, or modify the Biden Administration’s proposed U.S. Navy plans, budgets, and programs for responding to China’s naval modernization effort.
