The No.13 class submarine chaser (第十三号型駆潜艇,, Dai 13 Gō-gata Kusentei) was 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, Soviet Union strengthened its Pacific Ocean Fleet. They increased the number of submarines they had. It was one of the threats that Japan faced. The No.13 class was planned to deal with it.
