The Type C escort vessels were simplified versions of the Ukurus built with the utmost speed and economy, so that they could be completed in just two to three months. A total of 132 units were ordered in late 1943, the first hulls were laid down in September 1943, and the first units were completed in February 1944, with construction continuing to the end of the war.  Electric welding was used extensively in their construction, reducing weight by almost 200 tons, but their inferior machinery limited their speed.

Units were numbered CD-1 through CD-227 using odd numbers only. Even numbers were assigned to the Type D escort vessels.
