The Ch-51s were completed in 1937 as submarine chasers. They were essentially smaller Ch-1s and were used as fast attack transports during the early days of the Pacific War. The ships were redesignated auxiliary submarine chasers in 1943 and their numbers were assigned to new construction of the Ch-28 class.
