On 3 January 1952, "Arikara" departed Pearl Harbor to deploy again to the western Pacific. By the end of the month, she was back in the Korean combat zone. During that tour of duty in the Far East, the tug served once more at Wonsan, as well as at Cho Do and Pusan, and stayed in the waters between Japan and Korea until the beginning of August. That fall, "Arikara" moved to the Marshall Islands to support Operation Ivy, a nuclear bomb test conducted at Eniwetok Atoll in November 1952. Although the conflict lasted into the summer of 1953, the tug saw no additional service in the Korean combat zone.
