China's People's Liberation Army Rocket Forces (PLARF) possess the DF-26B intermediate-range ballistic missile, known as the "Guam Killer," capable of reaching U.S. facilities on Guam.
The DF-26B allows China to target US Navy warships operating near regions China considers to be within its sphere of influence. This capability means that all those expensive US Navy warships notably aircraft carriers will be vulnerable to attack from the DF-26B. The DF-26B carries the nickname “carrier killer.”
The United States faces a double-edged sword: it needs to have its forces deployed nearer to China so that it can reliably respond to any provocation by China. Those forces must be large enough to rollback what will be basically a full-court press (militarily speaking) by China.
If the DF-26 missile is indeed a capable killer of US vessels, the Chinese will have a relatively cheap way to thwart expensive and difficult-to-replace US vessels.
