Ship project history: Hei-Gata C1 type. Built under 3rd Supplementary programme of 1937. Attack submarines, intended specially for attacks of enemy combat ships. They were designated as "model C" (Hei-Gata) and were created on the basis of Kaidai 6b type fleet submarine, were very similar to B type submarines, differing, first of all, by armament: number of TTs has increased from 6 to 8, and torpedo stowage was increased to 19-20, TTs took places on four in two separated compartments, arranged one over another. At the expense of abandoning from aviation the gun was transferred to a bow, and deck in an aft part was strengthened for possibility to carry "A" type midget submarine. Double-hulled, endurance was about 90 days.

Modernizations: early 1943, I16: was converted to transport submarine; - 1 x 1 - 140/40, torpedoes stowage was decreased; + 1 14m Daihatsu-type landing craft, deck cargo

1943-44, some survived: + 2-shiki 2-go radar

Naval service: I22 was lost after 5/10/1942 off Malaita (Solomons), under miscellaneous versions, she was sunk 5/10/1942 by US aircraft or 12/11/1942 by US MTB 122 SW off New Guinea. I18 was sunk 11/2/1943 in Solomons area by seaplane from US cruiser Helena and destroyer Fletcher. I24 was sunk 10/6/1943 NE off Attu by ramming of US patrol craft 487. I20 after 30/8/1943 was lost, presumably sunk 3/9/1943 NW off Espirito Santo by US destroyer Ellett. I16 was sunk 19/5/1944 in Solomons area by US escort destroyer England.
