The U.S. Strategic Command officially assessed that the Chinese People’s Liberation Army Navy (PLAN) operates six Jin-class (Type 094) ballistic missile submarines, constituting China’s first credible sea-based nuclear deterrent.Each vessel is equipped with up to 12 submarine-launched ballistic missiles. This capability provides China with a naval second-strike option and is part of a broader expansion of its strategic forces.
United States operates 14 Ohio-class SSBNs, each capable of carrying up to 24 Trident II D5 SLBMs. Under treaty limits, 20 launchers are active per boat.
Russia maintains approximately 11 SSBNs, including Delta IV and Borei-A-class submarines. These platforms launch R-29RMU Sineva or RSM-56 Bulava SLBMs with ranges above 8,000 km. Each submarine can carry up to 16 missiles, many with multiple warheads.
France operates four Triomphant-class SSBNs, each equipped with 16 M51.2 or M51.3 SLBMs.
United Kingdom relies solely on four Vanguard-class SSBNs for its strategic nuclear forces. These submarines are armed with Trident II D5 SLBMs (acquired from the United States), each with a potential load of up to eight warheads.
Development began in the late 1990s to replace the Type 092 (Xia-class) SSBN, which was China's first attempt at creating a sea-based nuclear deterrent. The lead vessel of the Jin-class was laid down in 1999, launched in 2004, and commissioned into the People's Liberation Army Navy (PLAN) in 2007.
Each Type 094 is equipped with 12 missile tubes capable of launching JL-2 submarine-launched ballistic missiles. The JL-2 missile has an estimated range of approximately 7,200 kilometers, (some Type 094 submarines have been upgraded to carry the more advanced JL-3 SLBMs, which have a range exceeding 10,000 kilometers).
These submarines are armed with six 533 mm torpedo tubes for defense against surface and underwater threats.
The Type 094 measures approximately 137 meters in length and 11.8 meters in beam, with a submerged displacement of around 11,000 tons. Powered by a pressurized water reactor driving a single shaft, it achieves submerged speeds exceeding 20 knots. Its nuclear propulsion system allows for virtually unlimited submerged endurance, constrained primarily by factors such as crew endurance and maintenance requirements. Specific details about its maximum operating depth are not publicly disclosed; however, estimates suggest it is comparable to similar SSBNs, which typically operate at depths of around 300 meters.
