China will be able to build four submarines at a time in a submarine manufacturing facility near the Yellow Sea.

A recently released footage from China's Ministry of National Defense showed that a Type 092 vessel, or the country's first nuclear missile sub, was launched.

The propaganda video shows a vessel that can carry 12 Chinese Julang-1 missiles, which have a firing distance of 2,000 kilometers.

The total amount spent by the Chinese government to build the submarine is 298 million yuan. The construction of nuclear submarines started in the '70s.

Type 092 is China's homegrown submarine. It was based in Qingdao and was first launched in 1981. The sub launched a missile for the first time in 1988.

Also called Xia, the Chinese submarine measures 120 meters long and 10 meters wide. It displaces 6,500 tons of water when it is at the surface of the sea.

China also opened a new submarine factory that can build four subs simultaneously. The new facility is under the new program of the People's Liberation Army Navy.

The facility is being finished by the Bohai Shipbuilding Heavy Industrial Corporation (BSHIC), the only submarine builder in the country.

The BSHIC builds Type 091 and 093 nuclear attack submarines and Type 092 and 094 ballistic missile submarines.

The factory has an assembly hall that is 430,000 square feet and has room for two parallel production lines. One line is for finishing the hull and the other is for attaching the submarine pieces together.

The assembly area is large enough for two modules to be assembled at one end. Another pair of assembled hulls can be fitted out before launch.

This facility is already in the process of building Type 095 subs, which has a single and hybrid pressure hull, pump jet propulsion and vertical launch system cells. The Type 095 is superior to the U.S.'s Los Angeles III and Russia's Akula II.
