[2] Foss was struck and killed instantly by a 20mm cannon shell during the first strafing run, making him one of the first U.S. casualties in the Pacific War.

Foss sailed from Boston on 22 September 1943 for the Netherlands West Indies to escort a tanker convoy back to New York.

Between 26 December and 9 October 1944, Foss operated on the New York-Derry convoy route, making seven voyages to build up forces in Europe for the Normandy invasion and to support the advance on the continent once the landings had been made.

Assigned to operational development activities in anti-submarine warfare, Foss sailed out of Washington, New London, Charleston, Norfolk, and ports in Florida during the next six years.

Six days later, she sailed for duty in Korea, where her special ability to provide power to the shore was used at Chinnampo, Inchon, and Hŭngnam in November and December.

In June 1957, Foss returned to the west coast and was decommissioned and placed in reserve at Mare Island Naval Shipyard on 30 October 1957.
