Private John R. Towle (AK-240) was laid down, under U.S. Maritime Commission contract, as Appleton Victory (MCV hull 162) by the Oregon Shipbuilding Corporation, Portland, Oregon, 9 December 1944; launched 19 January 1945; sponsored by Mrs. John Goodland, Jr.
She was delivered to the Maritime Commission, thence to the American Mail Line for operation, 23 March 1945. She operated along the Pacific coast for a year, was returned to the Maritime Commission.
Appleton Victory was transferred to the Army Transportation Service (ATS) at New York City, in June 1946. Later returned to the U.S. West Coast, she was renamed Private John R. Towle, 31 October 1947, and, under that name, continued to serve ATS until returned to the Maritime Commission; transferred to the Navy, and designated T-AK-240 in March 1950.
Between 1950 and 1955, the Victory ship, assigned to the Military Sea Transportation Service and manned by a civil service crew, continued cargo operations in the Pacific Ocean.
Then reassigned to the Military Sea Transportation Service in the Atlantic, she began preparations for her first Antarctic resupply mission. During the southern summers of 1956–57, 1957–58, 1959–60, and 1960–61 she steamed south to deliver cargo to McMurdo Sound. On 20 January 1957, when delivering supplies, the then master of the vessel Capt John C Nissen-Wiis helped commemorate the opening of New Zealand's Scott's Base together with Sir Edmund Hillary and other dignitaries at Pram Point, Antarctica.
The ship made annual visits to Greenland to resupply the US Air Force base in Thule and Sonderstrom.
Needed elsewhere, the ice-strengthened AK did not return to Antarctic waters until the 1963–64 season. Since then, however, and into 1970, she returned annually to support the military and civilian personnel working there. She was active in Antarctic re-supply as late as March 1980.
During July 1974 Towle sustained ice damage to her hull off of Hamilton Inlet Labrador, Canada, and was assisted by the icebreaker USCGC Edisto (WAGB-284).On 25 August 1980 Private John R. Towle was returned to the U.S. Maritime Administration and laid up in the National Defense Reserve Fleet, James River Group, Lee Hall, Virginia. She was struck from the Navy List on 31 July 1982 and was sold for scrapping on 4 June 1982.
