The DF-21 is a family of Chinese ballistic missiles developed by the People's Republic of China. It is primarily designed for medium-range strategic strikes and can carry both conventional and nuclear warheads. The DF-21 has several variants, including the DF-21A, which is known for its mobility and quick launch capabilities. One notable version of the DF-21 is the DF-21D, which is specifically designed to target naval vessels, making it a significant component of China's anti-access/area denial strategy. The missile's range and accuracy enhance China's military capabilities in the Asia-Pacific region, contributing to its deterrence posture against potential adversaries.
