Japanese shipbuilder Kawasaki Heavy Industries (KHI) has launched the 10th Soryu-class diesel-electric attack submarine (SSK) for the Japan Maritime Self-Defense Force (JMSDF), the company said in a press statement.
The 84 m-long boat, which has been named Shoryu (with pennant number SS 510), was launched on 6 November in a ceremony held at KHI’s facilities in Kobe. It is the fifth submarine of the class to be built by KHI, with the other five having been built by Mitsubishi Heavy Industries. Shoryu was laid down in January 2015 and is expected to enter service with the JMSDF in 2019.
The ninth of the class, Seiryu, was launched in October 2016 and is expected to be commissioned next year.
According to Jane's Fighting Ships , the Soryu class has a beam of 9.1 m, a hull draught of 8.4 m, and a displacement of 2,947 tonnes when surfaced and of 4,100 tonnes when submerged. Powered by two Kawasaki 12V 25/25 diesel engines and four Kawasaki Kockums V4-275R Stirling air-independent propulsion (AIP) engines, each of the platforms has a top speed of 20 kt when submerged and of 12 kt when surfaced.
The Soryu class is equipped with six 533 mm bow tubes that can fire the Japanese-developed Type 89 heavyweight torpedo. The boats are also capable of deploying the UGM-84C Harpoon medium-range anti-ship missile against surface targets. Each boat has also been equipped with two underwater countermeasure launchers.
