Etorofu Class Escort Vessels

(Type C Escort by Takeshi Yuki scanned from "Color Paintings of Japanese Warships")

The 14 units of the Etorofu Class were an improved version of the Shimushu Class. The first unit was laid down in 1942 and completed in March 1943. The offensive-minded IJN did not accord a high priority to the construction of escort vessels for protection of their merchant shipping. The Etorofu Class and the four Shimushu Class escorts were thought to be sufficient to meet their needs. In 1942 and the first-half of 1943, the abysmally poor performance of the USN Bureau of Ordnance's inadequately-tested Mark-14 torpedoes validated Japanese thinking.
