The Dong Feng 31 (simplified Chinese: 东风-31; traditional Chinese: 東風-31; lit. 'East Wind-31'; NATO reporting name CSS-10)[5] is a third-generation long-range, road-mobile, three stage, solid-fuel rocket intercontinental ballistic missile (ICBM) in the Dongfeng missile series developed by the People's Republic of China. It is designed to carry a single 1-megaton thermonuclear weapon. It is a land-based variant of the submarine-launched JL-2. It is operated by the People's Liberation Army Rocket Force (PLARF). In 2009, the Chinese inventory was estimated as under 15 DF-31 missiles and under 15 DF-31A missiles.[6] US Air Force National Air and Space Intelligence Center estimates that as of June 2017, five to ten Mod 1 and over fifteen Mod 2 launchers were operationally deployed.[7]
