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.
