The United States military still holds an edge in several key areas, but China’s rapid military modernization is closing the gap, especially in scenarios close to its mainland, this comprehensive comparison provided by COMPARE.EDU.VN explores the strengths and weaknesses of each nation. To gain a deeper understanding of the strategic balance and potential future conflicts, explore further insights on defense capabilities, power projection, and technological advancements.
1. Assessing Air Base Vulnerability
How vulnerable are US air bases to Chinese attacks? Once holding a major advantage, the U.S. now faces approximate parity or even disadvantages in some scenarios due to China’s missile advancements.
From 1996 to 2017, the scenario has evolved drastically. Initially, the U.S. enjoyed a significant advantage in both scenarios: one closer to Mainland China, potentially involving Taiwan, and another farther away, such as the Spratly Islands. However, by 2017, the situation shifted to approximate parity in the Spratly Islands scenario and a Chinese advantage in the Taiwan scenario. This change is primarily attributed to China’s development of ballistic and cruise missiles targeting U.S. air bases.
1.1. The Evolution of China’s Missile Capabilities
How has China’s missile arsenal evolved over time? China’s arsenal has grown significantly, with improved accuracy and range that poses a threat to U.S. forward air bases.
China’s missile capabilities have evolved rapidly. In 1996, China possessed a limited number of conventionally armed ballistic missiles. By 2017, its inventory included roughly 1,400 ballistic missiles and hundreds of cruise missiles. Although most are short-range, a growing number of intermediate-range ballistic missiles can reach U.S. bases in Japan. The accuracy has also improved from hundreds of meters in the 1990s to as little as five or ten meters today. Weapon ranges have increased from short (less than 1,000 km) to medium (1,000–3,000 km).
1.2. Potential Impact on U.S. Air Operations
How could missile attacks affect U.S. air operations? Attacks could shut down critical air bases for days or weeks, challenging the U.S.’s ability to gain air superiority.
RAND models of attacks on Kadena Air Base, the closest U.S. air base to the Taiwan Strait, indicate that even a small number of accurate missiles could disrupt flight operations for critical days. A committed attack might close a base for weeks. While U.S. countermeasures like improved defenses, hardened shelters, faster runway repair, and aircraft dispersion can mitigate the threat, the growing number and variety of Chinese missiles pose a significant challenge. This may force the U.S. to operate from bases farther from conflict zones, complicating efforts to achieve air superiority.
2. Comparing Air Superiority
Who holds the upper hand in air superiority, the U.S. or China? While the U.S. maintains an advantage, China has significantly narrowed the gap through modernizing its air force.
The United States has historically maintained a qualitative edge in air superiority. However, China’s advancements have narrowed this gap. In any East Asian scenario, U.S. Air Force and U.S. Navy aircraft play a crucial role in countering Chinese attacks.
2.1. U.S. Advantages in Air Warfare
What advantages does the U.S. possess in air warfare? The U.S. has improved existing aircraft and introduced fifth-generation aircraft like the F-22 and F-35.
Since 1996, the United States has improved existing aircraft and introduced fifth-generation aircraft, including the F-22 and F-35. These advanced aircraft provide significant advantages in air combat.
2.2. China’s Modernization Efforts
How has China modernized its air force? China has replaced obsolete aircraft with modern fourth-generation designs, narrowing the qualitative gap with the U.S.
China has replaced many of its obsolete second-generation aircraft with modern fourth-generation designs. These aircraft now constitute roughly half of the PLA Air Force’s fighter inventory.
2.3. Impact on Force Requirements
How have these changes affected U.S. force requirements? U.S. force requirements have increased significantly, potentially making it difficult to prevail in certain scenarios.
Tactical and operational air combat models indicate that U.S. requirements have increased significantly since 1996. In a 2017 Taiwan scenario, U.S. commanders might struggle to find the basing required for U.S. forces to prevail in a seven-day campaign. Extending the campaign duration would leave ground and naval forces vulnerable to Chinese air operations for a longer period. The Spratly Islands scenario would be less demanding, requiring roughly half the forces of the Taiwan scenario.
3. Assessing Airspace Penetration Capabilities
How easily can the U.S. penetrate Chinese airspace? China’s improved air defenses have made it more difficult, especially near Taiwan.
The development of Chinese air defenses has raised concerns about operating in or near Chinese airspace. In 1996, China’s long-range surface-to-air missile (SAM) systems were primarily Chinese duplicates of the obsolete Russian SA-2 missile.
3.1. Evolution of Chinese Air Defenses
How have China’s air defenses evolved? China has deployed more sophisticated missile systems with longer ranges and integrated them into a formidable air defense system.
By 2010, China had deployed roughly 200 launchers for “double-digit SAMs.” The newer missiles have more sophisticated seekers and ranges of up to 200 km. Combined with more capable fighter aircraft and new airborne warning and control system–equipped aircraft, the Chinese integrated air defense system (IADS) has become a formidable obstacle.
3.2. U.S. Countermeasures and Limitations
What measures has the U.S. taken to counter Chinese air defenses? The U.S. has improved penetration capabilities with stealth aircraft and SEAD (suppression of enemy air defenses) aircraft.
At the same time, U.S. air forces have made improvements to their penetration capabilities, with the addition of stealth aircraft and new SEAD aircraft. These advancements mitigate the impact of Chinese defenses to some extent.
3.3. Impact on Strike Capabilities
How has this affected U.S. strike capabilities? The ability to penetrate and strike targets opposite Taiwan with minimal risk has declined significantly, but the ability to reach targets in the Spratly scenario remains more robust.
Target coverage models show net gains for China, with its improved IADS reducing the ability of even the improved U.S. forces to penetrate Chinese airspace at moderate risk. Although standoff attack capabilities, stealth, and SEAD mitigate the impact of Chinese defenses, the ability to penetrate and strike targets opposite Taiwan with minimal risk to the U.S. aircraft involved declines significantly between 1996 and 2017. The U.S. ability to penetrate to targets in the Spratly scenario remains far more robust, partly because the target set is closer to the coast and because scarce U.S. assets can be concentrated.
4. Assessing U.S. Air Base Attack Capabilities
How effective are U.S. air attacks on Chinese air bases? The U.S. can effectively close Chinese air bases, particularly in the Spratly Islands, but the inventory of standoff weapons is finite.
Since 1996, the development of new generations of precision weapons has given the United States new options and greater punch. Virtually all of the iron bombs used by U.S. forces today are equipped with guidance packages, such as the Joint Direct Attack Munition, turning them into all-weather, precision weapons.
4.1. Advancements in U.S. Precision Weapons
What advancements have been made in U.S. precision weapons? The U.S. now utilizes guidance packages that turn iron bombs into precision weapons, along with an array of standoff weapons.
At longer ranges, U.S. forces can utilize an array of stand-off weapons, capable of hitting targets from hundreds of kilometers away and deployed from a growing variety of platforms.
4.2. Impact on Chinese Air Base Operations
How have these advancements impacted Chinese air base operations? U.S. attacks can close Chinese runways for longer periods, particularly in the Spratly Islands scenario.
Runway attack models suggest that, in 1996, U.S. air attacks could close Chinese runways for an average of eight hours. This had increased to between two and three days by 2010, and it remained roughly similar through 2017. In all four snapshot years, U.S. air forces could effectively close all of China’s air bases opposite the Spratly Islands for the first week of operations.
4.3. Limitations and Considerations
What limitations does the U.S. face in attacking Chinese air bases? The inventory of standoff weapons is finite, and performance in a longer conflict would depend on a wider range of factors.
While ground attack represents a rare bright spot for relative U.S. performance, it is important to note that the inventory of standoff weapons is finite, and performance in a longer conflict would depend on a wider range of factors.
5. Examining Chinese Anti-Surface Warfare Capabilities
How effective is China’s anti-surface warfare? China has made significant strides in putting U.S. aircraft carrier strike groups (CSGs) at risk, especially near Taiwan.
The PLA has focused on neutralizing U.S. ground-based airpower and putting U.S. aircraft carrier strike groups (CSGs) at risk. China has developed a credible and increasingly robust over-the-horizon (OTH) intelligence, surveillance, and reconnaissance (ISR) capability.
5.1. Advancements in ISR Capabilities
How has China improved its ISR capabilities? China has launched military imaging satellites and deployed OTH radar systems to enhance its surveillance capabilities.
China launched its first operational military imaging satellites in 2000 and deployed its first OTH skywave radar system in 2007. The skywave system can detect targets and provide a general location out to 2,000 km beyond China’s coastline.
5.2. Development of Anti-Ship Ballistic Missiles
What threat do China’s anti-ship ballistic missiles pose? These missiles present a new threat dimension for U.S. naval commanders, though countermeasures are being developed.
China’s development of anti-ship ballistic missiles—the first of their kind anywhere in the world—presents a new threat dimension for U.S. naval commanders. The kill chain for these missiles will pose great difficulties for the PLA, and the United States will make every effort to develop countermeasures.
5.3. Submarine Modernization
How has China’s submarine fleet evolved? The modernization of Chinese air and submarine capabilities represents a challenging threat to CSGs.
Between 1996 and 2015, the number of modern diesel submarines in China’s inventory rose from two to 41, and all but four of theses boats are armed with cruise missiles (as well as torpedoes). RAND modeling suggests that the effectiveness of the Chinese submarine fleet rose significantly between 1996 and 2010 and will continue to improve.
6. Evaluating U.S. Anti-Surface Warfare Capabilities
How effective is the U.S. in anti-surface warfare? The U.S. retains a formidable ability to destroy Chinese amphibious forces, though this ability has declined somewhat since 1996.
The U.S. ability to destroy Chinese amphibious forces has declined since 1996 but remains formidable. China’s total amphibious ship capacity is on track to double between 1996 and 2017.
6.1. Amphibious Warfare Capabilities
How has China’s amphibious warfare capacity changed? China’s amphibious ship capacity is doubling, and they are deploying more sophisticated anti-submarine warfare assets.
China has also deployed larger numbers of more sophisticated anti-submarine warfare helicopters and ships. RAND modeling suggests that the expected damage that U.S. submarines might inflict has declined since 1996, but U.S. submarines alone would still be able to destroy almost 40 percent of Chinese amphibious shipping during a seven-day campaign.
6.2. U.S. Cruise Missile Developments
What progress has the U.S. made in developing anti-ship cruise missiles? The U.S. military has refocused on developing missiles better suited to the high-threat environment.
Over the past several years, the U.S. military has refocused on developing missiles better suited to the high-threat environment. Although U.S. capability against Chinese amphibious forces has declined somewhat, a combination of submarine, air, and surface attacks would still pose a serious threat to Chinese amphibious forces and their ability to conduct or sustain an amphibious invasion.
7. Assessing U.S. Counterspace Capabilities
How advanced are U.S. counterspace capabilities compared to China? While the U.S. has a larger orbital infrastructure, its counterspace capabilities remain relatively underdeveloped.
The United States, with 526 operational satellites, has a far more extensive orbital infrastructure than does China, with 132 satellites (as of January 2015). However, China has been accelerating its space efforts.
7.1. U.S. Satellite Infrastructure
How does the U.S. satellite infrastructure compare to China’s? The U.S. has a significantly larger number of operational satellites.
The United States has a far more extensive orbital infrastructure than China. However, China has been accelerating its space efforts.
7.2. U.S. Counterspace Developments
What counterspace capabilities does the U.S. possess? The U.S. has deployed systems designed to jam enemy communication satellites.
In 2004, the Counter Communications System, designed to jam enemy communication satellites, reached initial operational capability. The U.S. military could also potentially utilize experimental or dual-use systems, such as laser ranging stations and the High-Energy Laser system.
8. Evaluating Chinese Counterspace Capabilities
How does China’s counterspace program compare to that of the U.S.? China has demonstrated kinetic anti-satellite capabilities and possesses jamming systems and high-powered radio transmitters.
China has pursued an extensive range of counterspace capabilities. It demonstrated a kinetic anti-satellite capability in 2007 with a missile test against a nonoperational Chinese weather satellite at an altitude of 850 km.
8.1. Kinetic Anti-Satellite Capabilities
What kinetic anti-satellite capabilities has China demonstrated? China has demonstrated the ability to destroy satellites in low earth orbit with missile tests.
China demonstrated a kinetic anti-satellite capability in 2007 with a missile test against a nonoperational Chinese weather satellite at an altitude of 850 km. China has also announced three tests of ballistic missile defense interceptors.
8.2. Non-Kinetic Counterspace Systems
What non-kinetic counterspace systems does China employ? China uses jamming systems and high-powered dual-use radio transmitters that could target U.S. satellites.
More worrisome are the PLA’s Russian-made jamming systems and high-powered dual-use radio transmitters, which might be used against U.S. communication and ISR satellites.
9. Comparing U.S. and China Cyberwarfare Capabilities
How do the U.S. and China stack up in cyberwarfare? The U.S. maintains an advantage, but both sides face significant vulnerabilities in the cyber domain.
China’s cyber activities have become a major source of concern in the United States and allied countries. There is strong evidence that many of the hostile cyber espionage activities emanating from China are tied to the PLA.
9.1. Chinese Cyber Activities
What is the extent of China’s cyber activities? China has maintained organized cyber units since at least the late-1990s and is implicated in numerous cyber espionage activities.
The PLA has maintained organized cyber units since at least the late-1990s.
9.2. U.S. Cyber Command and Capabilities
What advantages does the U.S. have in cyberwarfare? The U.S. Cyber Command works closely with the National Security Agency and can draw on its sophisticated toolkit.
Under wartime conditions, the United States might not fare as poorly in the cyber domain as many assume. Cyber Command works closely with the National Security Agency and can draw heavily on the latter’s sophisticated toolkit.
9.3. Cybersecurity Vulnerabilities
What vulnerabilities do both sides face in the cyber domain? Both sides might face significant surprises, and U.S. logistical efforts are particularly vulnerable due to reliance on unclassified networks.
Both sides might nevertheless face significant surprises in the cyber domain during a conflict, and U.S. logistical efforts are particularly vulnerable, since they rely on unclassified networks that are connected to the Internet.
10. Assessing Nuclear Stability
How stable is the nuclear balance between the U.S. and China? The U.S. maintains a significant numerical advantage in warheads, ensuring a retaliatory capability.
The nuclear scorecard evaluates crisis stability in the bilateral nuclear relationship rather than the advantage enjoyed by one side or the other. Specifically, the scorecard examines the survivability of both sides’ second-strike capabilities in the face of a first strike by the other.
10.1. Chinese Nuclear Modernization
How has China modernized its nuclear forces? China has increased the quantity and quality of its nuclear forces, including road-mobile ICBMs and ballistic missile submarines.
China has modernized its nuclear forces steadily since 1996, increasing their quantity and improving quality. It has improved survivability through the introduction of the road-mobile DF-31 (CSS-9) and DF-31A ICBMs and the Type 094 Jin-class ballistic missile submarine (SSBNs).
10.2. U.S. Nuclear Arsenal
How does the U.S. nuclear arsenal compare to China’s? The U.S. has a numerical advantage in warheads of at least 13 to one, ensuring a retaliatory capability.
Despite additions to the Chinese nuclear force and U.S. reductions, even by 2017, the United States will still enjoy a numerical advantage in warheads of at least 13 to one. A Chinese first strike could not plausibly deny the United States a retaliatory capability in any of the snapshot years considered.
10.3. Survivability of Nuclear Forces
How survivable are each country’s nuclear forces? Chinese survivability has improved significantly, making a disarming first-strike against China unlikely.
For its part, Chinese survivability has improved significantly. Nuclear exchange modeling suggests that, as late as 2003, only a handful of Chinese systems might have survived a U.S. first strike—and even this outcome would have depended largely on China deploying its single, unreliable Xia-class SSBN (ballistic missile submarine) prior to an attack. In the 2010 and 2017 cases, more Chinese warheads survive, and no foreign leader could contemplate a disarming first-strike against China with any degree of confidence.
