The '''DF-2''' ('''CSS-1''') is China's first [[medium-range ballistic missile]] (MRBM), with a 1,250&nbsp;km range and a 15-20&nbsp;kt nuclear warhead. It received the western designation of CSS-1 (stands for "China Surface-to-Surface").<ref>[http://www.globalsecurity.org/wmd/world/china/df-2.htm DF-2 / CSS-1] {{Webarchive|url=https://web.archive.org/web/20090910094642/http://www.globalsecurity.org/wmd/world/china/df-2.htm |date=2009-09-10 }} GlobalSecurity.org</ref> 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.<ref>[http://www.globalsecurity.org/wmd/world/russia/r-5.htm R-5 / SS-3 SHYSTER] {{Webarchive|url=https://web.archive.org/web/20181007223118/https://www.globalsecurity.org/wmd/world/russia/r-5.htm |date=2018-10-07 }}. [[GlobalSecurity.org]]</ref> But some western authors still attribute the design to Chinese specialists [[Xie Guangxuan]], [[Liang Sili]], [[Liu Chuanru]], [[Liu Yuan (engineer)|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 [[List of nuclear weapons tests#Tests of live warheads on rockets|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.<ref>[http://www.sinodefence.com/strategic/missile/df2.asp DongFeng 2 (CSS-1) Intermediate-Range Ballistic Missile] {{Webarchive|url=https://web.archive.org/web/20110103031120/http://www.sinodefence.com/strategic/missile/df2.asp |date=2011-01-03 }} Sinodefence.com</ref>
