The No.13 class submarine chaser (第十三号型駆潜艇,, Dai 13 Gō-gata Kusentei) were a class of submarine chasers of the Imperial Japanese Navy (IJN), serving during and after World War II; there were three sub classes, however the IJN's official document calls all of them the No.13 class.

Background

• In 1938 the Soviet Union strengthened its Pacific Ocean Fleet, increasing the number of submarines it possessed; the No.13 class was designed to counter this potential threat to Japanese shipping.

Ships in classes

No.13 class

• Project number K8. 15 vessels were built in 1939-42 under the Maru 4 Programme (Ship # 180 – 183) and the Maru Rin Programme (Ship # 184 – 194). And after the Maru Rin Programme vessels were equipped with a kitchen and food storage between bridge and the chimney for a long cruise.

No.28 class

• Project number K8B. 31 vessels were built in 1941-44 under the Maru Rin Programme (Ship # 221 – 232) and the Maru Kyū Programme (Ship # 440 – 458). They abolished a slant of stern for mass production.

No.60 class

• Project number K8C. 3 vessels were built in 1943-44 under the Kai-Maru 5 Programme (Ship # 5341, # 5342 and 5344). They were changed inner hull design from the No.28 class. Therefore, there is not a difference of appearances.
