The JL-1 is China’s first submarine-launched ballistic missile (SLBM) with a range of 1,700- 2,150 km and carrying a single 200-500 kT nuclear warhead.  China’s Type 092/Xia-class nuclear powered ballistic missile submarine (SSBN) carries up to 12 JL-1 missiles. The Xia-class is China’s first SSBN and was launched in 1981, commissioned in 1987 and successfully launched its first SLBM in 1988. 
It is not believed that the Xia-class submarine has ever left Chinese coastal waters due to vulnerabilities related to slow speed, a noisy engine, and an unreliable reactor.  The Xia-class underwent a refit from 1995-2000, but it remained vulnerable to antisubmarine warfare platforms.  The Xia-class was replaced by Jin-class submarines launched in the 2004-2012 timeframe. With the Xia-class SSBN being removed from service, it is believed only about 15-20 JL-1 missiles remain.
