USS Ulua (SS-428), a Balao-class submarine, was the only ship of the United States Navy named for the ulua, an important food fish of the tropical Pacific Ocean. She was never completed. Ulua's keel was laid down on 13 November 1943 at Philadelphia, Pennsylvania, by the Cramp Shipbuilding Company, but the curtailment of U.S. Navy construction programs in the closing days of World War II resulted in the suspension of further construction on 12 August 1945.
