Type 092 Xia Class SSBN

In 1981 China launched the Xia-class nuclear-powered ballistic Missile submarine (SSBN), derived from the Han-class SSN. A ballistic missile submarine force would enhance Beijing's assurance of an effective retaliatory capability, as well as strengthening her deterrent posture. Despite a potential for operations in the Pacific Ocean, capabilities would be very limited against modern Western or Russian ASW capabilities.
