New Orleans, Louisiana on 20 September. A month of leave and upkeep followed, and on 24 October, Angler got underway for Jacksonville, Florida. She continued on to Newport to unload her torpedoes on 2 November, and arrived at New London on 6 November. Angler sailed to Portsmouth, New Hampshire in February 1946 to begin deactivation. She returned to New London on 21 April, and was decommissioned there on 12 February. Following her recommissioning on 2 April 1951, Angler held shakedown in the Caribbean Sea. She then began operations from her home port of New London. In October 1952, Angler was decommissioned and entered the General Dynamics Corporation yard at Groton, Connecticut, for overhaul and conversion. During the overhaul, one of her four diesel engines was removed to make room for advanced sonar equipment, part of her conversion to a "hunter-killer submarine". She was redesignated SSK-240 in February 1953. Upon completion of overhaul, Angler was recommissioned in September 1953 and rejoined the Atlantic Fleet. Following her shakedown in the West Indies from November 1953-March 1954, she returned to New London. She then operated along the East Coast and in the West Indies for the next two years, taking part in numerous Atlantic Fleet exercises, and spent the period from January through April 1956 undergoing overhaul at the Portsmouth Naval Shipyard. Angler made a training cruise to the West Indies, then returned to the East Coast. In October, she deployed to northern Europe and visited several ports in Britain before returning in December to New London. Angler spent the first eight months of 1957 participating in exercises along the East Coast. On 27 September, she was underway for Europe to take part in NATO fleet exercises. She then visited Dieppe, France and the Isle of Portland, England before returning to New London. Her final operation of the year was a training cruise to Bermuda in November. From 24 February-23 March 1958, Angler participated in Operation "Springboard," held in the West Indies and Caribbean, following those evolutions with numerous training exercises. On 3 November, Angler once again entered the Portsmouth Naval Shipyard for overhaul. Repairs were completed in March 1959, and the submarine resumed her schedule of operations and exercises along the East Coast. She also rendered services to the Submarine School, New London. In 1960, the ship reverted to her original designation, SS-240. On 24 October 1962, Angler commenced her first deployment
