The Taigei-class submarines is a new class of attack submarines developed for the JMSDF. It is the successor to the S?ry? clas swith better underwater endurance than its predecessors. 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 S?ry? class, making it possible for the submersible to travel longer and at higher speeds under water than conventional diesel-electric submarines.

The hull design of the Taigei class is said to not differ too much from the S?ry? class but will be 100 tons heavier than its predecessor. However, the Taigei-class submarines will be more advanced as they are equipped with newer equipment such as sonar systems, snorkel power generation system. The Taigei class will use lithium-ion batteries much like the JS ?ry? and JS T?ry? submarines. The submarine will likely use the Type 18 torpedo, which project name as “G-RX6”. Taigei, will be converted to a test submarine,the JMSDF can increase operating days and strengthen monitoring activities with their attack submarines while the test submarine will accelerate research and development.
