The USS Sea Devil (SSN-664) was a Sturgeon-class attack submarine built for the United States Navy, representing a significant component of Cold War maritime operations. Constructed by Newport News Shipbuilding and Dry Dock Company in Newport News, Virginia, the contract was awarded on 28 May 1964. The keel was laid on 12 April 1966, and after a relatively smooth construction process with minor delays, the vessel was launched on 5 October 1967. Mrs. Ignatius J. Galantin sponsored the launch, and the submarine was commissioned into service on 30 January 1969. Following her commissioning, Sea Devil underwent sea trials beginning on 26 January, marking the start of her active service. Designed as a 637-class fast attack hunter-killer submarine, she was notable for her power and endurance, attributes symbolized by her namesake—the sea devil, a large and formidable manta ray. Her primary operational base was Norfolk, Virginia, where she was assigned to Submarine Division 62. Throughout her career, she operated out of Norfolk into at least 1977 and later was assigned to Submarine Squadron 4 in Charleston, South Carolina, from the mid-1980s until her decommissioning in 1991. Her missions included patrolling the far north Atlantic, often surfacing through ice in the Arctic, and monitoring Russian vessels and ports—typical Cold War reconnaissance and surveillance activities. She also participated in submarine stalking missions, tracking Russian submarines with stealth and precision. Deemed outdated by the early 1980s, Sea Devil was taken out of service for repairs in 1981. She was officially decommissioned on 16 October 1991 and stricken from the Naval Vessel Register on the same day. Her dismantling and scrapping commenced on 1 March 1998 at the Puget Sound Naval Shipyard, with the process completed on 7 September 1999. Her nuclear fuel was stored until 2001 before being transferred to the Naval Reactors Facility in Idaho. The USS Sea Devil's service exemplifies Cold War submarine operations and the technological evolution of undersea warfare during her era.
