As noted, the novelty of the submarine lies in the reduced cabin, which improves its noise characteristics and reduces hydrodynamic resistance. The submarine also received an improved snorkel system, a next-generation sonar system to reduce signature. In addition to materials that reduce the submarine’s visibility, the designers built an innovative sound-absorbing coating on the hull cladding. Also, old Stirling engines were removed from Taigei and replaced by new lithium-ion batteries.
The hull is armed with six 533 mm torpedo tubes for use with Type-89 torpedoes and Harpoon anti-ship missiles.
The displacement of the submarine is 3 thousand tons, the hull length is 84 meters, and the width is 9.1 meters. The crew consists of 70 people.
