USNS Private John R. Towle (T-AK-240) was a Greenville Victory-classcargo ship that served as a commercial cargo ship during the final year of World War II. Post-war she was acquired by the U.S. Army as USAT Private John R. Towle until the 1950s when she was assigned to the U.S. Navy's Military Sea Transportation Service for various duties, including runs to Antarctica's McMurdo Sound.
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.
U.S. Army service
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.
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.
