Shimushu Class Escort Vessels

(Shimushun 1940)

The four units of the Shimushu Class were ordered by the IJN in 1937 as general purpose escorts. They were also fitted with minesweeping gear. This gear was removed in May 1942 and the classes' depth charge capacity was doubled to 24 DCs. Experience against American aircraft also resulted in an increase to 15 Type 96 25-mm AA guns. By late 1943, the class was fitted with a 3-inch trench mortar, Type 22 radar, Type 93 sonar, 6 depth charge throwers and 60 Type 2 depth charges to combat the increasing submarine menace.
