The Japanese naval forces have been replenished with another Soryu-class attack submarine. Solemn ceremony of transferring the submarine to the fleet took place on Wednesday at the shipyard in the city of Kobe.
The Toryu (Fighting Dragon) submarine was built at the Kawasaki Heavy Industries (KHI) shipyard in Kobe and is the twelfth and last Soryu-class submarine to enter the country's navy. Further, the Japanese submariners will be armed with a new type of submarine.
"Toryu" is the second in the series to receive lithium-ion batteries, which have twice the capacity of conventional lead-acid batteries.
The submarine was laid down in January 2017 and launched on November 6, 2019. The length of the submarine is 84 m, the width is 9,1 m, the height is 10,5 m, the draft is 8,4 m, the surface / submarine displacement is 2950/4100 t, the crew is 65 people.
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.
