"China currently maintains a minimal intercontinental nuclear deterrent using land-based intercontinental ballistic missiles (ICBMs). The Dong Feng-5 (DF-5) liquid-fueled missile, first deployed in 1981, has a range of 13,000 km and carries a single multi-megaton warhead. Twenty are believed to be deployed in central China, southwest of Beijing. Unlike China's earlier ballistic missiles, which were stored in caves and moved out for launch, the DF-5 can be launched directly from vertical silos—but only after a two-hour fueling process. In order to increase the survivability of the DF-5s, dummy silos are placed near the real silos. The DF-5's range gives it coverage of all of Asia and Europe, and most of the United States. The south-eastern US states are at the edge of the missile's range."
