The Dong Feng 4 (Chinese: 东风-4; pinyin: Dōng Fēng Sì; lit. 'East Wind 4') or DF-4 (also known as the CSS-3) is a first-generation two-stage Chinese intercontinental ballistic missile[7] with liquid fuel (Nitric acid/Unsymmetrical dimethylhydrazine). It was thought to be deployed in limited numbers in underground silos beginning in the late 1970s and early 1980s. The Dong Feng 4 has a takeoff thrust of 1,224.00 kN, a takeoff weight of 82000 kg, a diameter of 2.25 m, a length of 28.05 m and a fin span of 2.74 m. The range of the Dong Feng 4, which is equipped with a 2,190 kg nuclear warhead with 3.3 Megaton yield, with a nominal range of 5,500 km. This gives it sufficient range to strike targets as far away as Russia, India, and American bases in the Pacific.[8] The missile uses an inertial guidance system, resulting in a large CEP of 1,500 meters. As of 2017, 10–15 launchers are deployed.[9]
