The Soryu class was built by Mitsubishi Heavy Industries and Kawasaki for the Japan Maritime Self-Defense Force. It continued Japan's large ocean-going conventional submarine line while adding air-independent propulsion and later lithium-ion battery technology.
Early Soryu boats used Stirling AIP to extend submerged operation, while later boats introduced lithium-ion batteries for improved underwater power management. The class combines torpedoes, anti-ship missile capability, modern sonar, and long-range patrol suitability.
Soryu-class boats became a major component of Japan's submarine force and influenced international discussion about advanced non-nuclear submarines. The class also set the stage for the follow-on Taigei generation.
