The SS-248 U.S.S. Dorado was launched at the Electric Boat shipyard at Groton, Connecticut on 23 May 1943. After fitting out, she was commissioned on 28 August, under the command of Lieutenant Commander Earle C. Schneider. With her trials completed, Dorado departed New London on 6 October 1943, bound for the Panama Canal Zone and the Pacific.

Scheduled to reach the Canal Zone on 15 October, Dorado was never heard from again. No definite cause for Dorado‘s loss was ever established. Suspicion rests most strongly on an American Mariner patrol bomber out of Guantanamo, which reported sinking a submarine on 12 October. German mines were also put forward as a possible cause, as was the possibility of an accident.
