The No.1-class submarine chaser (第一号型駆潜特務艇,, Dai Ichi Gō-gata Kusen-Tokumutei) was a class of auxiliary submarine chasers of the Imperial Japanese Navy (IJN), serving during World War II. 200 vessels were built under the Maru Kyū Programme (Ship # 500–599) and the Maru Sen Programme (Ship # 2001–2100).

Background

[edit]

In 1939 the Imperial Japanese Navy had two diesel-engined harbour tugs built, No.1182 and No.1183. (Other contemporary Japanese harbour tugs were powered by compound steam engines). They had wooden hulls and were designed so that they could be converted to fishing boats after hostilities ended.[1] The two tugs, which were completed in 1940,[2] formed the basis for a class of auxiliary subchasers.

The IJN evaluated them, confirmed that they were effective subchasers, and in 1941, ordered 100 vessels. Their wartime performance was good, but they were always troubled by insect damage because their hull was wooden. Those that survived the war played an active part in the sweeping of magnetic mines in company with the No.1-class auxiliary patrol boats.
