The last in the series of diesel-electric submarines of the Soryu class for the country's Navy launched in Japan


In Japan, the last Soryu class diesel submarine was launched for the country's Navy, called Toru (Fighting Dragon). The submarine is the twelfth submarine of this class, the sixth built at the Kawasaki Heavy Industries shipyard (six more submarines built at the Mitsubishi Heavy Industries shipyard) and the second in the series to receive lithium-ion batteries. According to the developers, these batteries have twice as much power compared to conventional lead-acid batteries.


The Toryu submarine was laid down in January 2017, the transfer to the Japanese Navy is planned in 2021.

The length of the NPS is 84 m, width - 9,1 m, height - 10,5 m, draft - 8,4 m, surface / underwater displacement 2950 / 4100 t, Crew - 65 persons.

The boat is equipped with a main power plant consisting of two Kawasaki 12V 25 / 25SB diesel engines and four air-independent power plants (VNEU) V4-275R produced by Kawasaki Kockums. The maximum speed in a submerged position - 20 nodes, in the surface - 12.

Armament: six 533-mm torpedo tubes with torpedoes "Type-89", "Type-80" and anti-ship missiles UGM-84C "Harpoon". The submarine is also equipped with PU firing targets.

It is noted that equipping an air-independent power plant reduces the visibility of the boat for sonar and is under water for about 14 days, unlike 4-5 days in diesel-electric submarines without VNEU. The submarine is also equipped with automated systems and GAS, allowing to increase the efficiency of reconnaissance.
