Yet there were just 67 actually completed, the others were cancelled. Originally the ships were to be used for anti-aircraft and submarine warfare after the Navy asked on 22 April 1943 for a basic 800 tons escort design.

General technical details of the Type D escort vessel had a standard displacement of 752 tons and as dimensions 69,5 x 8,6 x 3,05 metres or 228 x 28.3 x 10 feet. The geared turbine machinery supplied via one shaft 2,500 hp allowing a speed of 17,5 knots and a range of 4.500 nautical miles with a speed of 16 knots. The crew numbered 160 men. The original armament consisted of 2-12cm/4.7” 45 cal dual purpose guns, 2x3-2,5cm/0.98” Type 96 anti aircraft machine guns, 12 Type 3 depth charge throwers and 1 depth charge chute for which 120 depth charges were carried.
