The Dongfeng series, typically abbreviated as "DF missiles", are a family of short, medium, intermediate-range and intercontinental ballistic missiles operated by the Chinese People's Liberation Army Rocket Force (formerly the Second Artillery Corps).
The DF-2 (CSS-1) is China's first medium-range ballistic missile (MRBM), with a 1,250 km range and a 15-20 kt nuclear warhead. It received the western designation of CSS-1 (stands for "China Surface-to-Surface"). It was long noted by western observers that the DF-2 could be a copy of the Soviet R-5 Pobeda (SS-3 Shyster), as they have identical look, range, engine and payload. The entire documentation for R-5 had been delivered from Soviet Union to China in the late 1950s.[4] But some western authors still attribute the design to Chinese specialists Xie Guangxuan, Liang Sili, Liu Chuanru, Liu Yuan, Lin Shuang, and Ren Xinmin. The first DF-2 failed in its launch test in 1962, leading to the improved DF-2A. The DF-2A was used to carry out China's test of a live warhead on a rocket on 27 October 1966 (detonated in the atmosphere above Lop Nor), and was in operational service from the late 1960s. All DF-2 were retired from active duty in the 1980s.
