Chōgei (ちょうげい) is a diesel-electric submarine of the Japan Maritime Self-Defense Force, and the fifth and final member of the Taigei class. Her name is written in kanji as "長鯨", literally meaning "giant whale",[1][better source needed][2][3] and this is the third use of the name, after the Meiji-era steamboat Chōgei Maru, and the Imperial Japanese Navy's Jingei-class submarine tender Chōgei.[2][3]
Construction and career
[edit]Chōgei was laid down on 19 April 2022 at Mitsubishi Heavy Industries Kobe Shipyard as part of the JMSDF's Mid-Term Defense Program of 2021, and was launched on 4 October 2024 after being christened. After being fitted out and underwent various trials, the vessel was handed over to the Japan Maritime Self-Defense Force for commissioning on 10 March 2026.[2][3][4]
