History

CH-5 was laid down on 25 January 1938 at the Mitsubishi Heavy Industries shipyard in Yokohama, launched on 28 July 1938, and completed and commissioned on 6 December 1938.[1]

She participated in the invasion of the Northern Philippines (Operation "M") in December 1941 where she was assigned to Sub Chaser Division 21 (SCD 21) led by Commodore Ota along with CH-4, CH-6, CH-16, CH-17, and CH-18.[1] SCD 21 was at the time assigned to Rear Admiral Hirose Sueto's 2nd Base Force under Vice Admiral Ibō Takahashi's Third Fleet.[1] She served mostly on escort duty during the war.[1]

CH-5 was surrendered to the British Royal Navy after the war in severely damaged condition and scuttled on 11 July 1946 off Singapore.[1] She was removed from the Navy list on 10 August 1946.[1]
