"Halfbeak" was launched 19 February 1946 by the Electric Boat Company at Groton, Connecticut, sponsored by Mrs. William Craig, and commissioned on 22 July 1946, Commander Evan T. Shepard in command. Service history. After shakedown in the Caribbean and along the Latin American coast to the Canal Zone, Ecuador, and Colombia, "Halfbeak" spent the next 3 years in training operations and fleet exercises out of New London, Conn., where she was part of SubRon 8. Entering the  Portsmouth Naval Shipyard 12 September 1949, "Halfbeak" was converted to a GUPPY II type submarine. Fitted with a snorkel to enable her to stay submerged for long periods of time and distinguished by a greatly streamlined superstructure, "Halfbeak" left Portsmouth 13 January 1950 to work with the Research and Development Group at New London. While conducting tests on special underwater sound equipment, she made a cruise to English waters, operating off Jan Mayen Island, in the winter of 1951. "Halfbeak" was engaged in further Caribbean exercises until 10 November 1954, when she sailed for her first Mediterranean cruise. Having visited  Gibraltar, Naples, Marseilles, Lisbon, and Valencia, Spain, the submarine returned to New London 2 February 1955. A similar cruise in 1956 was punctuated by the Suez Crisis, and "Halfbeak" remained in the eastern Med operating with the 6th Fleet until January 1957 helping to maintain the peace in that crucial region. Her duties took another turn as 28 July 1958 she departed for the Arctic, where with the nuclear submarine she operated under and around the polar ice pack to gather information in connection with the International Geophysical Year. During these operations, "Skate" sailed under the Arctic ice pack to  reach the North Pole 11 August and continued to cruise freely there repeating the visit 6 days later. Local operations and exercises, primarily submarine and fleet maneuvers in the Caribbean but also NATO maneuvers, occupied "Halfbeak" until 1963, when she resumed her role testing and evaluating sonar and other underwater sound equipment out of New London. James Bamford in Body of Secrets claims that around September 1965, "Halfbeak" conducted for the NSA a classified SIGINT mission off the Kola Peninsula . She was detected by Soviet forces, and had to hide for many hours below its maximum permissible depth before escaping . These events were omitted from the official ship's history. "Halfbeak" was awarded the Battle Efficiency "E" for 1966 and 1967 and held the "E" for Submarine Division 102 for 1968. "Halfbeak" was decommissioned and simultaneously struck from the Naval Register, 1 July 1971. She was sold for scrapping, 13 July 1972.
