"Sigourney" arrived at San Pedro, Calif., on 31 May and entered the Bethlehem Steel Co. Shipyard for an overhaul, remaining there until 3 September. She moved to San Diego the next day and, a month later was underway, for New York City via the Panama Canal, arriving there on 20 October. In October, the destroyer was ordered to Charleston, S.C., to prepare for inactivation. On 20 March 1946, she was placed out of commission, in reserve, with the Atlantic Reserve Fleet.
