The Type 092 ballistic missile nuclear submarine (Long March 6 ballistic missile nuclear submarine) is the first nuclear-powered ballistic missile submarine (also known as strategic missile nuclear submarine) developed by China, NATO codenamed “Xia” class. It is equipped with 12 Julang-1 submarine-launched ballistic missiles (NATO codename CSS-N-3).

      Construction of the Type 092 nuclear submarine started in the Huludao Shipyard in Liaoning in the 1970s, launched in 1981, delivered in August 1983, and entered service in 1987. In 1985, the first underwater missile launch test failed. In September 1988, an underwater missile launch test was successfully carried out and a Julang-1 missile was successfully launched. A major modification was later carried out in 1995.
