Tokyo, November 2, 2015 — Kawasaki Heavy Industries, Ltd. today held a ceremony marking the launch of the submarine Sekiryu, which was built for the Japan Ministry of Defense (MOD) at its Kobe Works' first dock at 10:05 AM. The ceremony was attended by a delegation of top MOD officials.

The submarine is the 8th Soryu class submarine built by Kawasaki, and the 27th built at this shipyard after World War II.

It provides high water pressure resistance performance by using high strength steel for its pressure hull, and superior submerged operations and propulsion performance by adopting an X-rudder. It also has Stirling engines for increased underwater endurance, a variety of automated systems, improved surveillance capabilities using high-performance sonar, increased stealth capabilities, and enhanced safety measures.
