USS Charr (SS/AGSS-328), a Balao-class submarine, was a ship of the United States Navy named for the charr. Construction and commissioning Originally named Bocaccio, SS-328 was renamed Charr on 24 September 1942 and launched 28 May 1944 by Electric Boat Company, Groton, Connecticut, sponsored by Mrs. W. F. Orkney; and commissioned 23 September 1944. First war patrol, December 1944 – March 1945 Pacific-bound, Charr cleared New London 5 November 1944, and reached Pearl Harbor 9 December. On 30 December, she was bound for action waters, as she sailed on her first war patrol off the northeast coast of Indo-China. On 29 January 1945, daring to lie at anchor in broad daylight for 4 hours one mile (1.6 km) off the coast, Charr sent two men ashore in a rubber boat to rescue a downed aviator. A second rescue mission came at the close of her patrol, when she escorted the badly damaged Dutch submarine HNLMS Zwaardvisch through the Java Sea and Lombok Straits to Fremantle, Australia, where the two submarines arrived 3 March. Second war patrol, March – May 1945 After refit, Charr cleared on her second war patrol, cruising in the Flores, Java, and South China Seas, and along the southern coast of Taiwan. She sailed for part of the patrol in coordination with and , and with them conducted an epic 4-day chase of the Japanese cruiser Isuzu and her three escorts. Finally, early in the morning of 7 April 1945, Charr maneuvered into firing position to find Isuzu down by the stern and listing, evidence of successful attack by Gabilan. Charr fired a spread of torpedoes, scoring three hits to send the cruiser to the bottom. Three days later, 10 April 1945, Charr made contact with another target, a coastal freighter, which she sank on the surface by gunfire. The submarine then headed on for a dangerous assignment, calling for intricate maneuvering, when she laid a minefield off Pulo Island on 14 April and 15 April. She put in at Subic Bay from 20 to 24 April to reload torpedoes, then sailed on to patrol off Formosa on lifeguard duty, during which she rescued one downed pilot. Third war patrol, June – July 1945 After refitting at Subic Bay from 21 May to 14 June 1945, Charr put out on her third war patrol, cruising in the Gulf of Siam with three other submarines.
