USS Crevalle (SS/AGSS-291), a Balao-class submarine, was a ship of the United States Navy named for the crevalle, the yellow mackerel, a food fish, found on both coasts of tropical America, and in the Atlantic as far north as Cape Cod. Construction and commissioning Crevalle was launched 22 February 1943 by the Portsmouth Navy Yard in Kittery, Maine, sponsored by Mrs. C. W. Fisher; and commissioned 24 June 1943. First and second war patrols, October 1943 – February 1944 Crevalle arrived at Brisbane, Australia, from New London 11 October 1943, and after replenishing there and at Darwin, put to sea 27 October on her first war patrol, in the Sulu and South China Seas. On 15 November she sank the passenger-cargo ship Kyokko Maru, almost 7,000 tons. On Thursday 18 November 1943, off the entrance to Manila Bay, Crevalle torpedoed the , incorrectly reporting Akitsu Maru as sunk. Crevalle made two more attacks on merchant ships before returning to Fremantle, Australia, for refit 7 December. Her second war patrol, in the South China Sea from 30 December 1943 to 15 February 1944, found her attacking a submerged Japanese submarine on 7 January, only to know the frustration of premature torpedo explosion. On 9 January she sunk a sampan with gunfire In a hazardous special mission, she laid mines off Saigon on 14 and 15 January, and on 26 January sent a Japanese freighter "Busho Maru" to the bottom. A surface action with a small patrol boat on 11 February sank the enemy craft, and on 15 February, Crevalle fired at several targets in a large convoy, prudently clearing the area before the results of her firing could be verified. Third and fourth war patrols, April – August 1944 On 16 March 1944 while refitting at Fremantle, Commander F. D. Walker assumed command, and on 4 April, Crevalle sailed for the South China Sea. She sank a freighter Kashiwa Maru on 25 April, and the oiler, Nisshin Maru (16,801 tons) 6 May, and on 11 May surfaced off Negros Island in the Philippines on another daring special mission. She rescued 40 refugees here, including 28 women and children, and 4 men who had survived the Bataan Death March and made their escape. She also took off the family of an American missionary, who having seen his family to safety, returned ashore at the last minute to continue his ministry among the
