PLAN 'Xia' class type 092/092G SSBN
The single Xia class SSBN (Type 092G/09II, 6,500t dived) was back into the sea after a 3-year long refit. This modernization project included a new black paint, a new bow mounted sonar (H/SQG-262B), a redesigned casing housing longer missile launch tubes, plus upgraded combat control systems for launching new SLBMs. Initially armed with 12 JL-1 (CSS-N-3) SLBMs (inertial guidance to 1,700km with a single 1.25MT nuclear warhead), it is now believed to carry the new JL-2 SLBMs (CSS-NX-4, with 3 or 4 MIRV at 90kT each, range 8,000km). For years Xia 406 has been PLAN's sole nuclear deterrence force, which appears limited and ineffective (although it was rumored that a 2nd boat was built but this was never confirmed). This reality suggests serious problems of the 092/JL-1 design and the submarine never entered series production. Instead it has become a valuable testbed for PLAN to shape its tactics and strategies for modern SSBN warfare since the first successful test fire of JL-1 SLBM in 1988. The latest news suggested that a JL-2 SLBM was successfully test-fired from 406 on June 16, 2005.
