JS Sōgei (Japanese: そうげい; Pennant number: SS-518) is a diesel-electric submarine of the Japan Maritime Self-Defense Force, and the sixth boat of the Taigei-class. Her name, written in kanji as "蒼鯨", translates to "blue whale".[1] She is the first Japanese naval vessel to bore that name, as the Imperial Japanese Navy had not used the name.[2][3]
Construction and career
[edit]Sōgei was ordered in the fisical year 2022 as part of JMSDF's Mid-Term Defense Program. She was laid down on 28 March 2023 at Kawasaki Heavy Industries' Kobe Shipyard, and launched on 14 October 2025.[1][4] The vessel would then undergo a fitting out process and a period of sea trials, being scheduled to be commissioned in March 2027.[2][3]
