The destroyer escort reached the Philadelphia Naval Shipyard on 22 November 1945 and, after pre-inactivation overhaul, was decommissioned on 14 June 1946 at Green Cove Springs. Earmarked for deferred disposal status on 21 March 1947, Bangust was taken to Charleston Naval Shipyard in June 1947. Towed there by Challenge (ATA-201) on 17 and 18 June, the ship remained in the yard until 13 August when, under tow of Tunica (ATA-178) she was taken back to Mayport, Fla., arriving the next day. Inactivated on 20 October 1947, Bangust was transferred to the government of Peru on 26 October 1951 under the terms of the Mutual Defense Assistance Program (MDAP). Her name was struck from the Naval Vessel Register on 18 April 1952. She was renamed Castilla (D.61) and served as such into the 1970’s.
Bangust earned 11 battle stars for her World War II service.<ref>Dictionary of American Naval Fighting Ships [http://www.history.navy.mil/danfs/b2/bangust-listi.htm]</ref>
