The JL-2 (Chinese: 巨浪-2; pinyin: Jù Làng Èr; lit. 'Giant Wave 2', NATO reporting name CSS-N-14) is a Chinese second-generation intercontinental-range submarine-launched ballistic missile (SLBM) deployed on the People's Liberation Army Navy's (PLAN) Type 094 submarines.
The JL-2 provides China with its first viable sea-based nuclear deterrent.[4]
Development
[edit]The JL-2 was developed as part of a larger program to replace the liquid-fuelled ballistic missiles developed from 1965 with solid-fuelled missiles.[5] The JL-2 was the SLBM variant of the land-based DF-31. Development of both missiles began in the mid-1980s,[6] with the SLBM having less priority.[7] The first JL-2 at-sea launch occurred in 2001 from a Type 031 submarine.[8][7] The missile suffered a series of testing failures. A successful test cycle was achieved in 2012.[6]
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]
Type 094 deterrence patrols with JL-2 missiles began in December 2015.[1] Each submarine may carry 12 missiles.[4]
Description
[edit]The JL-2 is a three-stage, solid-fueled missile,[10] with a maximum range of 3,900 nmi (7,200 km).[4] It carries a single[11] 1 megaton warhead.[3] According to the Center for Strategic and International Studies, the missile may carry 3-8 MIRVs with yields of 20, 90, or 150 kilotons.[2]
