Upon the outbreak of the Korean War, "Chauncey" was recommissioned 18 July 1950, and on 1 November, sailed to join the Atlantic Fleet. "Chauncey" operated from her home port at Norfolk, Virginia, along the east coast, and in the Caribbean, until 10 January 1953, when she got underway for the west coast on the first leg of a round-the-world voyage. Reaching Sasebo, Japan, 11 February, "Chauncey" screened the carriers of TF 77 off Korea during the final months preceding the Korean Armistice, and in June sailed on to call at Hong Kong, Singapore, Colombo, Aden, Athens, Naples, Cannes, and Gibraltar before her return to Norfolk 6 August.
