The Dong-Feng 21 represents China's first solid-fuel land-based missile. Development started in the late 1960s, and was completed around 1985-86 but was not deployed until 1991. It appears to be a land-based version of the JL-1 missile launched from submarines.
The U.S. Department of Defense estimates that China has 60-80 missiles, and 60 launchers. As well as a nuclear warhead of around 300kt, it is thought that high explosive, submunition and chemical warheads are also available.The DF-21A was operational by 1996 and has improved accuracy, with both GPS and a radar-based terminal guidance system in a redesigned nose. It is thought to have a lower yield, around 90kt, but longer range (up to 2500 km).
