  • Japan has launched a new Taigei-class sub every year since 2020.
  • These "Big Whale" subs are expected to hunt Chinese warships should a war break out.
  • Their advanced capabilities and stealth make them prime candidates for ambushes on Chinese warships.

In October, Kawasaki Heavy Industries launched Japan’s newest submarine in a ceremony at its shipyard in Kobe, Japan. Named, JS Raigei (“Thunder Whale” in Japanese), the diesel-electric attack sub is the fourth boat of the Taigei-class, which translates to “big whale.”
