context_page_description: 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.
context_section_description: 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 the 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.  Now it is known that the whole documentation for R-5 had been delivered from Soviet Union to China in the late 1950s.  But some western authors still attribute the entire 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 in 1966 (detonated in the atmosphere above Lop Nor), and was in operational service since late 1960s.  All DF-2 were retired from active duty in the 1980s.
