USS Sculpin (SSN-590), a Skipjack-class nuclear-powered submarine, was the second ship of the United States Navy to be named for the sculpin. Construction and commissioning Sculpin′s keel was laid down on 3 February 1958 by Ingalls Shipbuilding in Pascagoula, Mississippi. She was launched on 31 March 1960, sponsored by Mrs. Fred Connaway, widow of Commander Fred Connaway, who was killed while commanding the first during World War II, and commissioned on 1 June 1961 with Commander C. N. Mitchell in command. Operational history 1960s Sculpin departed Pascagoula on 8 June for her designated home port, San Diego, California. Following her arrival there, she began a period of shakedown training. In July, she held special trials and tests in the Puget Sound area and then returned to San Diego for type training. In August, Sculpin cruised to Pearl Harbor for two weeks before returning to San Diego. She operated off the West Coast before entering the Mare Island Naval Shipyard for post-shakedown availability in October. This was completed in late March 1962, and Sculpin returned to her home port. Following training operations, in early May she deployed for the western pacific visiting Pearl Harbor and then continued her special operations in the western Pacific, upon completing operations visited Naha, Okinawa and Pearl Harbor returning to San Diego in August. The nuclear submarine participated in local training operations, ordnance evaluation projects, and fleet exercises until entering the Mare Island Naval Shipyard in early January 1963 for a hull survey. Sculpin returned to San Diego at the end of the month, conducted type training for two months and, on 29 March, got underway for a dependents' cruise. The submarine returned to Mare Island in April for restricted availability and remained there until August when she returned to San Diego and commenced local operations. She was the first submarine leaving Mare Island after the Thresher Disaster. Sculpin was in Pearl Harbor, in early December, en route to the western Pacific, when defective piping forced her to sail back to Mare Island for repairs. She returned to San Diego on 25 February 1964, and operated from that port until early April. On 8 April, Sculpin sailed for duty with the Seventh Fleet. Prior to reporting, she made port calls at Pearl Harbor, Sydney, and Subic Bay. For the remainder of her deployment, Sculpin operated in and out of Subic Bay, and Naha, Okinawa, with the
