DF-4
Sign in to saveAlso known as 北约代号：CSS-3
The Dongfeng 4 () or DF-4 (also known as the CSS-3) is a first-generation two-stage liquid-fuelled Chinese intercontinental ballistic missile. It was estimated to be deployed in limited numbers in underground silos beginning in the late 1970s and retired around 2023, deploying around 10 to 15 launchers in the late 2010s. The yield of its nuclear warhead was estimated at 3.5 megatons.

The Dongfeng 4 () or DF-4 (also known as the CSS-3) is a first-generation two-stage liquid-fuelled Chinese intercontinental ballistic missile. It was estimated to be deployed in limited numbers in underground silos beginning in the late 1970s and retired around 2023, deploying around 10 to 15 launchers in the late 2010s. The yield of its nuclear warhead was estimated at 3.5 megatons.
The DF-4's rocket propellant is the hypergolic mixture of nitric acid and unsymmetrical dimethylhydrazine. The DF-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 DF-4, equipped with a 2,190 kg nuclear warhead with a 3.5 megaton yield, was nominally 5,500 km. This gives it sufficient range to strike targets as far away as Russia, India, and American bases in the Pacific. It was the first Chinese missile capable of striking the Soviet capital city of Moscow and US assets on Guam. The missile uses an inertial guidance system, resulting in a large CEP of 1,500 meters.
