Japan’s Mitsubishi Heavy Industries (MHI) has launched the first Soryu-class diesel-electric attack submarine (SSK) for the Japan Maritime Self-Defense Force (JMSDF) to be equipped with lithium-ion batteries.<\/p>\n

The 84 m-long boat, which has been named Oryu<\/i> (with pennant number SS 511), entered the water on 4 October in a ceremony held at MHI’s facilities in Kobe.<\/p>\n

The submarine is the 11th of the class and the sixth to be built by MHI, with the other five having been built by Kawasaki Heavy Industries. Oryu<\/i> was laid down in March 2015 and is expected to enter service with the JMSDF in 2020.<\/p>\n

The launch comes after GS Yuasa, a Kyoto-based developer and manufacturer of battery systems, announced in February 2017 that Japan would become the first country in the world to equip SSKs with lithium-ion batteries in place of lead-acid batteries.<\/p>\n

At the time the company said the batteries, which store considerably more energy than the lead-acid batteries, would be mounted on the final two Soryu-class boats for the JMSDF: SS 511 and SS 512.<\/p>\n

According to Jane’s Fighting Ships<\/i> , 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.<\/p>\n

The previous boats of the class have been fitted with two Kawasaki 12V 25\/25 diesel generators and four Kawasaki Kockums V4-275R Stirling air-independent propulsion (AIP) engines, and use lead-acid batteries for energy storage.<\/p>\n

Each of the platforms has a top speed of 20 kt when submerged and of 12 kt when surfaced.<\/p>\n

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.<\/p>\n
