USS Icefish (SS-367), a Balao-class submarine, was a ship of the United States Navy named for the icefish, any member of the family Salangidae, small smeltlike fishes of China and Japan. These fish are also collectively known as whitebait. Construction and commissioning Icefish was launched on 20 February 1944 by the Manitowoc Shipbuilding Companyat Manitowoc, Wisconsin, sponsored by Mrs. Stanley P. Mosely, wife of Captain Mosely, and commissioned on 10 June 1944. First patrol, September – November 1944 After trials and diving tests in Lake Michigan, voyages down the Mississippi, and shakedown out of New Orleans, Icefish joined the Pacific Fleet at Pearl Harbor 22 August. Assigned to Vice Admiral Charles A. Lockwood's Task Force 17 (Supporting Submarines Pacific Fleet), she joined "Banister's Beagle's" (consisting of Comdr. Alan B. Banister in and ) and departed 9 September on her first war patrol which took her into Luzon Straits and the South China Sea. October 1944 was a peak month in the war of U.S. submarines on Japanese shipping: 322,265 tons were sunk, and almost one-third of that total consisted of tankers. In October Icefish and Drum together sank 26,901 tons of enemy shipping in "Convoy College", code name for the area extending across the East China Sea from Luzon Strait to Formosa and the coast of China. Icefish sank a 4,000-ton cargo vessel on 23 October and on 26 October she was credited with sinking a transport of 10,000 tons. She terminated her first war patrol at Majuro, Marshall Islands, 13 November. Second and third patrols, December 1944 – April 1945 Icefish departed Majuro 8 December on her second war patrol in company with and . This patrol lasted 43 days with no results and she was forced to return to Pearl Harbor 20 January 1945 due to materiel difficulties. The third war patrol began 20 February when she departed Pearl Harbor with Sawfish and . This patrol was also conducted in the East China Sea, northeast and east of Formosa. As the war was coming to an end and Japanese shipping had dwindled away largely due to the "Silent Service", Icefish'''s third war patrol terminated after 60 days at Apra Harbor, Guam.
