USS Croaker (SS/SSK/AGSS/IXSS-246), a Gato-class submarine, was the first ship of the United States Navy to be named for the croaker, any of various fishes which make throbbing or drumming noises. Construction and commissioning Croaker′s keel was laid down on 1 April 1943 by Electric Boat Company in Groton, Connecticut. She was launched on 19 December 1943, sponsored by the wife of Admiral William H. P. Blandy, and commissioned on 21 April 1944, with Commander John E. Lee in command. Service history World War II Croaker arrived at Pearl Harbor from New London on 26 June 1944, and on 19 July put to sea on her first war patrol, sailing to the East China and Yellow Seas. In a series of brilliantly successful attacks which won her the Navy Unit Commendation, she sank the cruiser Nagara on 7 August, an auxiliary minesweeper, Taito Maru, on 16 August, and two freighters, Daigen Maru No. 7 on 14 August and Yamateru Maru on 17 August. During this patrol, she served as lifeguard during air strikes on the Bonin Islands. She refitted at Midway Atoll from 31 August to 23 September, when she sailed in a coordinated attack group for the same area on her second war patrol. Again successful, she sank the freighters Shinki Maru on 9 October, and Hakuran Maru on 23 October. She shadowed a convoy on 23–24 October, sank the freighter Mikage Maru, and damaged Gassan Maru with her last torpedo. Tubes empty, she returned to Midway to fuel, and pushed on to Pearl Harbor, arriving for refit on 10 November. Croakers third war patrol, in the Luzon Straits and South China Sea from 13 December 1944 to 12 February 1945, found her making no contacts with enemy shipping, but providing essential lifeguard service during strikes on Luzon preparatory to the invasion landings in Lingayen Gulf. She refitted at Fremantle, Australia, and on 12 March sailed for a patrol off the coast of Indo-China twice interrupted by the need to return to Australia for repairs. She refitted at Subic Bay, Philippines from 22 April to 15 May, then sailed for her fifth war patrol, in the Java Sea. On 30 May, she attacked a convoy of three small oilers guarded by an escort, with unconfirmed results, and on 5 June returned to Fremantle. Her final war patrol – from 1 July to 13 August – found her assigned to
