Several Japanese submarines are currently being used by the Japanese Maritime Self Defense Force. These include the Soryu -class diesel-electric attack submarines and the Taigei-class nuclear-powered attack submarines. The JMSDF did not announce the number of each type that it would like to buy.
Kawasaki Heavy Industries
Kawasaki Heavy Industries has a long history. They make submarines and other naval vessels. It was established in 1870s to build ships, and then it expanded into other industries. The company began producing supertankers, aircraft, and railroad machinery by the end. In the postwar years, the company began building containerships for the Chinese Navy.
Japan's Maritime Self Defense Force is expanding its submarine fleet. The force also plans to develop stealth submarines, in order to stop China acquiring a formidable undersea navy. The 29SS will take five years to develop and is expected in service by 2031. The SS-510 Shoryu, the lead submarine, will be developed and tested at a cost of 76 billion yen.
Japanese Maritime Self-Defense Force
Submarines serve the Japanese Maritime Self-Defense Force on a regular basis. These subs are used for coastal surveillance as well as defense duties. The MSDF needs to maintain a position that allows it at least two submarines per sea strait in Japan. This means that six divisions will be equipped with sixteen submarines.
The Japanese Maritime Self-Defense Force submarine fleet consists primarily of mine sweepers and submarines. The chief of maritime staff is responsible for commanding the fleet. It can transport approximately 624,000 ton.
Taigei-class nuclear-powered attack submarine
Japan's newest nuclear powered attack submarine, the Taigei is a nuclear-powered sub. It can carry 70 crew members and measures 84m long, 9.1m beam and 10.4m depth. Its displacement is approximately the same as the Soryu class SSKs. It has separate female-only compartments which allow up to six women on board.
The Taigei-class submarine has the same hull design as the Sry-class submarine, but is heavier. This allows it travel farther and more quickly. It is also equipped upgraded equipment including upgraded sonar systems and snorkel power generation. The Taigei-class also plans to use lithium-ion batteries for its propulsion system.
