The {{nihongo|Cruiser submarine Type-C|巡潜丙型潜水艦|Junsen Hei-gata sensuikan}} was one of the first classes of submarine in the Imperial Japanese Navy (IJN) to serve during the Second World War. Type-C submarines were better armed than the Type-A and Type-B. The Type-Cs were also utilized as Kō-hyōteki or Kaiten mother ships, for this reason they were not equipped with aviation facilities.

Class variants

The Type-C submarines were divided into three classes:

{{nihongo|Type-C|丙型（伊十六型）|Hei-gata, I-16-class}}
{{nihongo|Type-C Mod.|丙型改（伊五十二型）|Hei-gata Kai, I-52-class}}
{{nihongo|Type V22B|第379号艦型|Dai-379-Gō kan-gata, Vessel number 379-class}}. However, the Vessel number 379-class was never built.

=''Type-C'' (''I-16'' class)=

Image:Japanese submarine I-18 in 1941.jpg

Project number S38 and S38B (Latter batch). They were based on the I-7 class. Eight boats were built between 1937 and 1944 under the Maru 3 Programme (Boats 44 - 48) and the Maru Kyū Programme (Boats 376 - 378).

Project number S37D. Twenty boats were planned under the Maru Tsui Programme (Boats 625 - 632) and the Kai-Maru 5 Programme (Boats 5141 - 5155). According to their Project number, they were one of the variants of the Type-B submarine. Seventeen boats were cancelled in late 1943, because the IJN was planning to build the {{nihongo|{{Interlanguage link|Type E submarine|ja|戊型潜水艦}}|戊型潜水艦|Bo-gata sensuikan}} which was to become the primary submarine in 1945.
