[7] 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.

[7] 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.

[7] For her fourth war patrol, Crevalle returned to the South China Sea, as well as cruising off the northern Philippines, between 21 June and 9 August 1944.

Fifteen seconds later, the boat took a sharp down angle, and submerged with the upper and lower conning tower hatches open, washing the lookout overboard.

During her voyage, the United States Navy Armed Guard detachment aboard an American Liberty ship mistook her for a Japanese submarine and opened fire on her with a 5-inch (127 mm) gun when Crevalle was in the Bass Strait south of Melbourne, Australia.

Crevalle suffered no damage or casualties..[12] In California, she underwent an overhaul Mare Island Naval Shipyard, followed by training at Pearl Harbor.

[7] In the Pacific Ocean on 15 February 1945, the American Liberty ship SS Charles F. Amidon — which reported her position as 36°55′N 126°05′W / 36.917°N 126.083°W / 36.917; -126.083 — mistook Crevalle for a Japanese submarine and opened gunfire on her at a range of 2,800 yards (2,560 m), firing eight rounds and claiming two hits.

[13] The submarine put to sea on her sixth war patrol from Pearl Harbor 13 March 1945 under the command of Captain Everett Hartwell Steinmetz.

Cruising in the East China Sea, she took up a lifeguard station during air strikes preparing for the Okinawa invasion, then on 23 – 25 April, made a hazardous search for a minefield believed to be located near the southern entrance to the Tsushima Straits.

[7] She returned to Guam to refit from 3 to 27 May, then sailed for her seventh war patrol in the northeast section of the Sea of Japan under the command of Captain Everett Hartwell Steinmetz.

[10] Returning to Pearl Harbor 5 July, she got underway once more on 11 August, but received word of the end of hostilities before entering her assigned patrol area.

[7] Recommissioned 6 September 1951, Crevalle took part in training, exercises, and fleet operations along the East Coast and in the Caribbean until 19 August 1955, when she was again placed out of commission in reserve at New London.

All of Crevalle's war patrols, save the interrupted fifth, were designated as "successful", and the first four won her the Navy Unit Commendation for distinguished performance of duty as well as four battle stars.
