The Sōryū class submarine or 16SS is a new class of diesel-electric submarine being built in Japan for use by the Japan Maritime Self-Defense Force. It is an evolved form of the Oyashio class submarine, currently the latest type of conventionally-powered submarine operated by the JMSDF, and it will have a larger displacement than any previous class of submarine used by post war Japan. It can be best visually distinguished from the Oyashio class by the X-shape of the tail planes.
The class will also have an Stirling AIP engine (4V-275R Mk-II, power output 75kW) licensed built by Kawasaki Heavy Industries system, allowing it to stay submerged for longer periods of time.[1]
