Kawasaki Delivers Twelfth Soryu-class Submarine to Japanese Navy

Kawasaki Heavy Industries today held a ceremony marking the delivery of the submarine Toryu to the Japan Ministry of Defense (MOD) at its Kobe Shipyard Nishihama Quay at 11:30 AM on March 24.

The ceremony was attended by a delegation of top MOD officials. The submarine is the 12th Soryu class submarine, and the 29th built at the Kawasaki Kobe Shipyard after World War II.

It provides superior submerged operation and propulsion performance, and high water pressure resistance by using high strength steel for its pressure hull. It also has lithium ion battery systems for increased underwater endurance, a variety of automated systems, improved surveillance capabilities by its high-performance sonar, increased stealth capabilities, and enhanced safety measures.

Construction of the submarine began in January 2017 and completed in November 2019.

With a displacement of 2,950 tons and a length of 84 meters, the submarine is powered by two Kawasaki 12V 25/25 SB-type diesel engines and one electric propulsion motor.
