The USS Swordfish (SSN-579) was a Skate-class nuclear-powered submarine of the United States Navy, notable for its pioneering role in undersea operations during the Cold War era. Constructed at Portsmouth Naval Shipyard in Kittery, Maine, her keel was laid on January 25, 1956, and she was launched on August 27, 1957. Commissioned on September 15, 1958, under Commander Shannon D. Cramer, Jr., Swordfish underwent her initial shakedown in the Atlantic Ocean before being assigned to the Pacific Fleet with Pearl Harbor as her home port in March 1959. She was one of the early nuclear submarines operating in the Pacific, completing over 35,000 miles in her first year, with more than 80% submerged. Her deployments included multiple WestPac cruises, during which she became the first nuclear submarine to operate in the western Pacific in 1960. Notably, she hosted foreign dignitaries such as Chiang Kai-shek of the Republic of China and President Carlos P. Garcia of the Philippines during cruises, demonstrating her strategic and diplomatic importance. Swordfish was involved in significant Cold War surveillance activities, including close-range observation of Soviet anti-submarine exercises in 1963 and photographing the first Soviet Yankee-class submarine. She underwent multiple overhauls, including becoming the first Pacific-based nuclear submarine to be overhauled at Mare Island in 1962 and receiving a refueling and SubSafe overhaul from late 1965 to August 1967. A notable incident occurred in March 1968, when Swordfish was involved in repairs related to the sinking of the Soviet K-129 submarine, with conflicting reports on whether she was damaged in a collision or ice pack. She also faced controversy in 1985 when a mishap caused flooding and reactor shutdown, but her crew's quick actions ensured her safe surfacing and return to port. Decommissioned on June 2, 1989, and dismantled in 1995, USS Swordfish played a significant role in Cold War undersea operations, exemplifying the advances in nuclear submarine technology and strategic reconnaissance. Her service underscored her maritime significance as a pioneering and active participant in Cold War naval operations.
