"Sigourney" was placed in full commission again on 7 September 1951 at Charleston, S.C. She underwent shakedown training at Guantanamo Bay in early 1952 and, in April, joined DesRon 322 with Norfolk as her home port. She conducted local operations from there until October when she entered the Norfolk Naval Shipyard for an overhaul which lasted until January 1953. She returned to Guantanamo Bay for refresher training until March, after which she operated out of her home port. On 29 June, "Sigourney" began a combined seven-month Far East tour and round-the-world cruise. While in Korean waters, the destroyer was attached to TF 77, the Fast Carrier Force, and TF 95, the United Nations Blockading and Escort Force.
