China's first deployed nuclear ballistic missile submarine
mediumThe Type 092 Xia class was China's first operational SSBN and a key step toward a sea-based nuclear deterrent.
The Type 092, NATO reporting name Xia, was China's first nuclear-powered ballistic missile submarine class deployed by the PLAN submarine force. It followed the Type 091 nuclear attack submarine experience and added a missile compartment for JL-1 submarine-launched ballistic missiles. The program was technically difficult and politically important: an SSBN gives a nuclear power a more survivable second-strike option, but only if the submarine, missiles, communications, and patrol procedures can work together reliably. The Xia class therefore matters even though later Chinese SSBNs are more capable. It was the prototype of China's sea-based deterrent.
