China’s strategic doctrine, on the other hand, is more focused on regional defense and protecting its national interests. However, China’s increasing military capabilities and growing global influence are leading to a more assertive foreign policy and a greater emphasis on projecting power beyond its borders.
2. A Detailed Comparison: Key Military Assets
To comprehensively answer “how big is China’s military compared to the US,” it’s essential to compare their key military assets across different domains.
2.1. Air Force: Wings of Power
The US Air Force (USAF) is widely considered the most powerful air force in the world, possessing a vast fleet of advanced aircraft, including fifth-generation fighters like the F-22 Raptor and F-35 Lightning II.

2.4. Nuclear Arsenal: Deterrence and Destruction
Both the US and China possess nuclear weapons, which serve as a deterrent against attack. The US has a larger and more diverse nuclear arsenal than China, consisting of land-based intercontinental ballistic missiles (ICBMs), submarine-launched ballistic missiles (SLBMs), and strategic bombers. China’s nuclear arsenal is smaller and primarily land-based.
| Category | US Military | Chinese Military |
|---|---|---|
| Air Force | More advanced technology & training | Rapidly modernizing aircraft |
| Navy | Largest & most capable | Largest in ship numbers, catching up |
| Ground Forces | Highly trained, tech-focused | Largest army, modernizing |
| Nuclear Arsenal | Larger, more diverse | Smaller, primarily land-based |
2.5. Cyber Warfare and Space Capabilities
In the 21st century, cyber warfare and space capabilities have become increasingly important aspects of military power. Both the US and China are investing heavily in these areas.
The US is considered a leader in cyber warfare, with advanced capabilities for both offensive and defensive operations. The US military also relies heavily on space-based assets for communication, navigation, and surveillance.
China has made significant progress in developing its cyber warfare capabilities and is believed to be a major player in cyber espionage and cyber attacks. China is also rapidly expanding its space program, launching satellites for military, civilian, and commercial purposes.
3. Scenarios and Regional Power Dynamics
The question of “how big is China’s military compared to the US” becomes particularly relevant when considering specific scenarios and regional power dynamics.
3.1. Taiwan Strait: A Flashpoint
The Taiwan Strait is a potential flashpoint between the US and China. China views Taiwan as a breakaway province and has not ruled out the use of force to reunify it with the mainland. The US, on the other hand, has a long-standing policy of “strategic ambiguity,” neither confirming nor denying whether it would intervene militarily to defend Taiwan.
In a potential conflict over Taiwan, China would likely seek to use its military to deter US intervention and overwhelm Taiwan’s defenses. The US would likely rely on its air and naval power to defend Taiwan and counter China’s military operations.
3.2. South China Sea: Maritime Disputes
The South China Sea is another area of potential conflict between the US and China. China claims sovereignty over much of the South China Sea, including islands and maritime features that are also claimed by other countries in the region. The US has consistently challenged China’s claims, conducting freedom of navigation operations in the South China Sea to assert its right to operate in international waters.
In a potential conflict in the South China Sea, China would likely seek to use its navy and air force to enforce its claims and deter US intervention. The US would likely rely on its naval and air power to maintain freedom of navigation and protect its allies in the region.
Conflicting territorial claims in the South China Sea highlight the complex geopolitical landscape and potential for military confrontation.
3.3. Global Power Projection: Beyond Regional Conflicts
Beyond regional conflicts, both the US and China are seeking to expand their global influence and project power around the world. The US maintains a network of military bases and alliances around the world, allowing it to project power globally. China is expanding its military presence overseas, establishing its first overseas military base in Djibouti and increasing its naval presence in the Indian Ocean and other regions.
The competition between the US and China for global influence is likely to continue in the coming years, with both countries seeking to expand their military capabilities and project power around the world.

According to a RAND report, in specific scenarios like a Chinese air base attack closer to mainland China, the US held a major advantage in 1996 and 2003. By 2010, this shifted to approximate parity, and by 2017, China had gained an advantage. This highlights China’s rapid military modernization.
4.2. Academic Studies
Academic studies on the US-China military balance offer varying perspectives. Some scholars argue that the US military is overstretched and that China’s growing military power is eroding US dominance. Others maintain that the US still possesses a decisive military advantage and that China’s military modernization is primarily defensive in nature.
4.3. Government Reports
Government reports from both the US and China provide insights into their respective military capabilities and strategies. The US Department of Defense publishes an annual report on China’s military power, which assesses China’s military modernization efforts and their implications for US security.

Economic growth is a key driver of military power. Both the US and China have large and growing economies, which allow them to invest heavily in their militaries. However, China’s economy has been growing at a faster rate than the US economy in recent years, which could allow it to close the military gap with the US.
5.3. Geopolitical Alignments
Geopolitical alignments can also influence the military balance. The US has a network of alliances with countries around the world, including Japan, South Korea, and Australia. These alliances provide the US with access to military bases and support, which enhances its ability to project power globally. China is seeking to build closer ties with countries in its region and beyond, which could challenge US dominance.
5.4. Strategic Decisions
Strategic decisions made by both the US and China will also influence the military balance. The US must decide how to allocate its resources and prioritize its military investments. China must decide how to use its growing military power and whether to pursue a more assertive foreign policy.
