The JL-2 (Chinese: 巨浪-2; pinyin: Jù Làng-2; lit. 'Giant Wave 2', NATO reporting name CSS-NX-14[3]) is a Chinese second-generation intercontinental-range submarine-launched ballistic missile (SLBM) slated for deployment aboard the People's Liberation Army Navy's Type 094 submarine. It succeeds the JL-1 SLBM deployed on the Type 092 submarine.
Development
The JL-2 is a naval variant of the land-based DF-31.[5][7] Their common 2-metre diameter solid fuel rocket motor was successfully tested in late 1983,[5] and research and development efforts were reorganized starting in 1985 to produce both missiles.[7]
The first JL-2 at-sea launch occurred in 2001 from a Type 031 submarine.[5][7] The program was delayed after a failed test in 2004.[5] Successful launches occurred in 2005 and 2008. The missile was successfully fired from a Type 094 submarine, the intended operational platform, for the first time in 2009.[5] A series of test launches occurred in 2012.[6][8] Another test launch occurred in January 2015.[9]
During the development of the missile, it was reported that China was considering modifying the missile to accommodate an anti-satellite warhead to give it a sea-based anti-satellite capability.[10]
According to latest source, 094 SSBN armed with JL-2 missiles began deterrent patrol in 2015.[1] The United States Department of Defense believes the missile will give the PLA Navy "its first credible sea-based nuclear deterrent."[11]
Description
The JL-2 is a three-stage, solid-fuelled missile.[3][4] Range estimates have included 7,400 km (4,600 mi)[6] to 8,000 km (5,000 mi).[5] Payload is a single[3] 250–1000 kt warhead;[4] or 3 to 4 (MIRV) 90 kt warheads,[5]
