Project history

Hei-Gata C3 type. Built under the 1941 War programme, repeated Hei-Gata C2 type, differing by decreased engine power: that allowed to raise an endurance significantly. Besides, these submarines had second 140mm guns and only 6 TTs. War programme provided building of two more subamrines (I57 and I59), but in 1943 this order was cancelled. 15 more boats (Nos5141-5155) of the same type were provided by the additional programme of 1942, but works have not been begun. Also 25 submarines of enhanced C4 type (Nos5156-5180, 2756t surfaced, 20.4kts surfaced, 1x1-140/40, 1x2-25, 8-533TT), planned under modified 5th Supplementary programme, were never ordered and cancelled in 1943.
