The Cruiser submarine Type-B (巡潜乙型, Junsen Otsu-gata) was a class of submarine in the Imperial Japanese Navy (IJN) which served during World War II. The Type-B submarines were similar to the Type-A apart from not having the headquarters institution.
Class variants
The Type-B sumbarines were divided into four classes:
- Type-B (乙型, Otsu-gata), the I-15 class
- Type-B Mod.1 (乙型改一, Otsu-gata Kai-1), the I-40 class
- Type-B Mod.2 (乙型改二, Otsu-gata Kai-2), the I-54 class
- V22A Type (第5115号艦型, 5115th vessel class). The 5115th vessel class submarines were not built and remained a design only.
Type-B (I-15 class)
Project number S37. Twenty boats were built between 1937 and 1944 under the Maru 3 Programme (Boats 37 - 42) and Maru 4 Programme (Boats 139 - 152).

Type-B Mod.1 (I-40 class)
Project number S37B. Six boats were planned under the Maru Kyū Programme (Boats 370 - 375), all boats were completed. On the outside this class looked the same as the I-15 class, however, they were built from high-tensile strength steel and equipped with diesel engines of a simpler design.

V22A Type
Project number S49A. Eighteen boats were planned under the Kai-Maru 5 Programme (Boats 5115 - 5132). However, all boats were cancelled in late 1943, because the IJN concentrated on production of Type-E submarine (戊型潜水艦, Bo-gata sensuikan) from 1945 onwards.
