The 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[edit]

The Type-C submarines were divided into three classes:

  • Type-C (丙型(伊十六型 Hei-gata, I-16-class?)
  • Type-C Mod. (丙型改(伊五十二型 Hei-gata Kai, I-52-class?)
  • 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)[edit]

I-18 in 1941

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).

Type-C Mod. (I-52 class)[edit]

Main article: I-52-class submarine
I-53 in 1945

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 Type-E submarine (戊型潜水艦 Bo-gata sensuikan?) which was to become the primary submarine in 1945.
