Celebes Island. On 4 October, a U.S. Navy PB4Y-1 Liberator patrol bomber mistakenly attacked her, dropping a bomb which landed from Mingo, inflicting no damage or casualties. She moored in Fremantle on 13 October. Her sixth war patrol, mostly reconnaissance duty, took place west of Borneo. On 25 December, Mingo made a night torpedo attack on a Japanese convoy on a run between Singapore and Brunei, Borneo. Beside damaging an escort gunboat, she sank loaded 9,486-ton tanker Manila Maru. The sinking of a maru of that name was prophetic, for the Japanese were only three months away from losing their hold completely on the ship's namesake, the Philippine capital. After assisting two other submarines in successful attacks, she returned to Fremantle on 29 December for repairs. Seventh war patrol Mingo took station at the South China Sea again for her seventh and last war patrol from 6 February–10 April 1945. On 14 February, she sailed to Fremantle to repair damage caused by a hurricane in which she had lost two men on 10 February. She departed on 19 February for further patrol off the Gulf of Siam before arriving in the Marianas on 10 April. En route to Hawaii on 14 August, Mingo received word of the end of hostilities. After a short stay at Pearl Harbor, she sailed for the West Coast. Japanese service, 1955–1966 On 1 January 1947 Mingo decommissioned at Mare Island and entered the Pacific Reserve Fleet. Recommissioned on 20 May 1955. Mingo was transferred on loan to Japan under the Military Assistance Program and renamed Kuroshio (SS-501) on 15 August. Her initial role was as an underwater training target for surface vessels. She continued to serve the Japan Maritime Self-Defense Force as Kuroshio until decommissioned on 31 March 1966. She was sunk as a target in 1973. Awards Mingo received five battle stars for World War II service. Five of her seven war patrols were designated "successful".
