Project history

Kaidai 3 (later Kaidai 3a, Large Admiralty 3a) type. Built under the 1923-1928 programme. Further development of Kaidai 2 type: displacement was increased on 300t at simultaneous decrease in a buoyancy for diving time reduction; hull and CT lines were a little changed. Double-hulled.

Modernizations

4.1945, I158: - 1 x 1 - 120/45; + 2 Kaiten human torpedoes.
