On 12 January 1953, Mount Baker sortied from San Francisco with a cruiser‑destroyer force for the largest, to that time, postwar training operation in the Pacific. Early in February she sailed for Sasebo, Japan, to resume combat duty. From March until the Armistice in July, Mount Baker gave efficient and essential service in the cause of a free Korea. Returning to San Diego early in the fall, she provided the fleet primarily with training ammunition, was overhauled, and 10 March 1954 sailed to support the 7th Fleet in operations off Japan and the Philippines.
