Type D (Class II)(even-numbered) Escort Vessels

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

Japanese production of diesel engines could not keep up with war-time demand. The Type D was designed as a Type C Class, but powered by a turbine engine. The turbines gave the Type D an extra knot of speed, but at the expense of higher fuel consumption and decreased unrefueled range. The exhausts were trunked into a tall funnel placed further forward than the funnel of the Type C Class. 143 units were ordered and the first unit was laid down in October 1943. Construction of Type D escorts continued until the end of the war. Beginning in January 1945, as a result of the national oil shortage, the design was modified so that the units of the Type D Class could be converted to burn coal.
