She remained in service until 1955 and attended the Coronation Review at Spithead in June 1953. After reduction to Reserve status she was laid-up at Portsmouth where she remained until placed on the Disposal List in 1961. The ship was sold to BISCO for demolition by CW Dorkin at Sunderland where she arrived in tow on 12th August that year.
