Scheduled to be commissioned in March 2022, Taigei will be reportedly followed by at least two sister units. As explained, the literal meaning of Taigei is “big whale”.
The 3000-ton submarine features a length of 84 meters and a width of 9.1 meters and can accommodate about 70 people. It has a diesel-electric propulsion.
The Taigei submarine is equipped with a sonar system with improved detection capability. What is more, it has an advanced, stealth-like design and a lithium battery system that ensure quiet operation and longer endurance.
The Taigei-class is the successor of the JMSDF’s Soryu-class diesel-electric submarine. Almost a year ago, Kawasaki Heavy Industries, another Japanese shipbuilder, launched the 12th Soryu-class unit, Toryu (SS-512). Toryu is planned to be handed over to the navy in 2021.
