Five Chinese Weapons of War America Should Fear

China's economy is on the rise—and so is its military. Should Washington be concerned?

In the last twenty years, China has quickly ascended from a regional to global military power. A generation ago, the People’s Liberation Army was armed with antiquated weapons and oriented towards a manpower-intensive “People’s War”. In the intervening period China has gone from a green to blue water navy, the air force is actively developing so-called fifth-generation fighters, and the army has been extensively modernized.

A vast array of new Chinese weapons are under development, some alarming in their potential.

China’s neighbors and the United States are observing China’s buildup with interest and concern. China is showing itself to be particularly interested in projecting military power in support of territorial claims in the East and South China Seas. Weapons that empower China to take decisive military action in support of such claims could escalate a regional crisis into a larger one involving Washington.

China recognizes the potential for conflict with the United States, however small, and is planning accordingly. China is pouring resources into weapons specifically designed to target American forces and limit their ability to operate near the Chinese mainland. These “anti-access, area-denial” (A2/AD) weapons have the potential to exclude American forces from China’s innermost defense zone: the so-called “First Island Chain” consisting of the Kuril Islands, Japan, Taiwan, the Philippines and Borneo.

The chances of a shooting war between China and the United States are remote, and neither is set on war with the other. However, the extent to which the interests contradict or compete with each another means war cannot be entirely ruled out. With that in mind, here are the five Chinese weapons the United States fears most.

DF-21D Anti-Ship Ballistic Missile

The most dangerous weapon to U.S. forces in the Asia-Pacific region is the Dong Feng-21D anti-ship ballistic missile (ASBM). Somewhat prematurely dubbed “the Carrier Killer”, the DF-21D is a medium-range ballistic missile specifically designed to attack American aircraft carriers, skirting the defenses of a U.S. naval task force to attack ships from above at hypersonic speeds.

DF-21D is a land-based system, with an estimated range of up to 1,500+km. Once launched, the missile would release a reentry vehicle traveling at speeds of up to Mach 10-12. The resulting velocity and kinetic energy—to say nothing of the reentry vehicle’s payload—would cause serious damage to even the largest naval vessels. Nobody knows for sure, but it is believed direct hits from a DF-21D could be enough to put an aircraft carrier out of action, or even sink it.

Mounted on a wheeled transporter and launcher, the DF-21D would be road-mobile and thus extremely hard to locate before launch. The reentry vehicle’s hypersonic speed would make it difficult—but not impossible—to shoot down.

The DF-21D has an Achilles’ heel, the so-called “kill chain” of sensors, relay stations, and command and control centers required to detect, identify, track, and hit a ship with a ballistic missile. There are many links in the chain leading to a successful DF-21D launch, and breaking just one would interrupt the entire process.

China would have to devote considerable reconnaissance assets to killing a carrier and maritime surveillance is not China’s strong suit. Land-based, over-the-horizon radars are imprecise, and maritime patrol aircraft, UAVs and submarines will be vulnerable to the carrier’s air wing. Only China’s satellites have the ability to provide tracking data, and those can be jammed or otherwise disabled.

The DF-21D was allegedly tested in early 2013, when two craters were observed in an outline of an aircraft carrier in the Gobi Desert.

The DF-21D weapon may be operational, but the kill chain is likely not, and it may be years before the entire system is fully operational. Still, the prospect of a weapon that can kill 5,600 Americans, destroy seventy aircraft, and destroy a pillar of American power projection worldwide is a sobering one to contemplate.

Chengdu J-20 Fighter

China’s first fifth-generation fighter, the J-20 is a large, twin-engine aircraft currently in the demonstrator phase. The J-20’s mission set is unknown, but the aircraft’s robust design seems to support it going in a number of different directions. The aircraft promises to be long-range, fast- and low-observable—if not outright stealthy. China has built three prototypes, the latest flew in early March 2014. The aircraft is projected to enter service some time around 2020.
