The JL-2 (Chinese: 巨浪-2; pinyin: Jù Làng-2; literally: "Giant Wave 2", NATO reporting name CSS-NX-14[1]) 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[edit]

The JL-2 is a naval variant of the land-based DF-31.[3][6] Their common 2-metre diameter solid fuel rocket motor was successfully tested in late-1983,[3] and research and development efforts were reorganized starting in 1985 to produce both missiles.[6]

The first JL-2 at-sea launch occurred in 2001 from a Type 031 submarine.[3][6] The program was delayed after a failed test in 2004.[3] 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.[3] A series of test launches occurred in 2012.[4][7] Another test launch occurred in January 2015.[8]

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.[9]

In 2012, the United States Department of Defense noted development had suffered repeated delays.[10] However, the following year, the Department assessed that the missile would reach initial operating capability that year, giving the PLA Navy "its first credible sea-based nuclear deterrent."[11]

Description[edit]

The JL-2 is a three-stage, solid-fuelled missile.[1][2] Range estimates have included 7,400 km (4,600 mi)[4] and 8,000 km (5,000 mi).[3] Payload may include multiple 90 kt warheads,[3] or a single 250–1000 kt warhead.[2] According to Hans Kristensen of the Federation of American Scientists, Chinese nuclear policy makes it unlikely that nuclear warheads are fitted to the JL-2 during peacetime.[11]
