and began three weeks of training operations out of Pearl Harbor. On 12 August, Allen M. Summer stood out of Hawaii to return to the war zone. However, when she was two days out, the Japanese capitulated. Nevertheless, the warship continued her voyage west. Following a two-day stop at Eniwetok, she got underway again on 21 August and, six-days later, rendezvoused with TG 38.3 in Japanese waters. After some three weeks of postwar patrols, first with TG 38.3 and later with TG 38.1, the destroyer put into Tokyo Bay on 16 September. She remained there only six days before getting underway for the Marianas on 22 August. The ship reached Saipan three days later but soon resumed her voyage back to the United States arriving on the west coast in October and assuming duty as a training platform for prospective destroyer crews. 1946 to 1952 These operations continued until May 1946 when the destroyer departed the west coast, bound for the Central Pacific to support Operation Crossroads, the atomic bomb tests conducted at Bikini Atoll in the Marshall Islands. At the conclusion of that assignment late that summer, she returned to her former west coast duty. On 23 February 1947, Allen M. Sumner began an extended cruise to the Far East which included visits to Australia, the Marianas, the Philippines, China, and Japan before her return to the west coast for an overhaul and subsequent local operations. That duty continued until early in 1949 at which time the ship was reassigned to the Atlantic Fleet. She transited the Panama Canal in mid-April and arrived in Hampton Roads, Virginia, on 20 April. Between the spring of 1949 and the spring of 1953, the destroyer conducted normal peacetime operations out of Norfolk. That routine was broken only by a tour of duty in the Mediterranean Sea with the 6th Fleet between November 1950 and March 1951. Otherwise, she cruised along the eastern seaboard and in the West Indies conducting training—particularly in antisubmarine warfare. 1953 to 1966 On 24 April 1953, the destroyer stood out of Norfolk, bound for her only assignment in the war zone during the Korean War. Steaming by way of the Mediterranean Sea, the Suez Canal, and Indian Ocean, Allen M. Sumner arrived in Yokosuka, Japan, early in June. After 10 days in port, she joined Task Force (TF) 77 in the Sea of Japan and began two months
