The Taigei-class submarines (29SS; (Japanese: たいげい; "Big Whale") is a new class of attack submarines after 2022, developed for the Japan Maritime Self-Defense Force. It is the successor to the Sōryū class.
The Taigei class is equipped with a large amount of lithium-ion batteries, as is the case with the eleventh and twelfth submarines of the Sōryū class (Ōryū and Tōryū), making it possible for the submersible to travel longer and at higher speeds under water than conventional diesel-electric submarines.
