   The Type 094 (NATO designation Jin class) nuclear-powered ballistic missile submarine is the second-generation SSBN of the Chinese navy. Its development possibly began in the early 1980s. It is a successor to the unreliable Type 092 or Xia class. The whole project is kept in secrecy.

   Speculations have been made, that development of the Type 094 class was assisted by Russian Rubin Design Bureau, however this information was not confirmed. Construction of the lead vessel began in 1999 and it was launched in 2004. It seems that the first boat was commissioned in 2010. The second vessel of the class was launched in 2007. Some sources claim that these Chinese ballistic missile submarines were plagued with various problems and design flaws. By 2013 Jin class boats were never sent on deterrent patrol missions. As of 2017 China operates 4 of these ballistic missile submarines. Some sources report, that a 5th submarines of this class is also planned.

   Externally the Jin class appears to be a scaled-up version of the previous Xia class. It also incorporates some technologies of the Type 093 (Shang class) nuclear-powered attack submarine. Hull of the submarine was enlarged to accommodate missile tubes and part of the nuclear reactor.

   The Jin class carries a total of 12 JL-2 (NATO designation CSS-N-5 Sabbot) submarine-launched ballistic missiles. Though originally these submarines were planned to carry 16 missiles.

   The JL-2 missile has an estimated maximum range of 8 000 km. It allows this boats to hold US territory within missile range, while operating from Chinese costal waters. Each JL-2 missile carries a single 250-1 000 kT nuclear warhead, or up to 3-4 smaller warheads with a yield of 90 kT each. These missiles were first deployed operationally in 2015.

   Other armament includes six 533 mm torpedo tubes. These can be used to engage hostile ships and submarines.

   Once on high alert these submarines can leave their bases and operate in China's coastal water, protected by the China's fleet. So the Jin class boats have high probability of surviving the first strike, once the country has been attacked.  However these submarines are not as advanced or stealthy as the Western ballistic missile submarines. Furthermore these are even inferior to the Russian submarines. China was always dragging behind in terms of submarine technology. It was reported that the Type 094 class boats are as noisy as the Russian Delta III class submarines, that were adopted back in the mid 1970s.
