USS Cygnus (AF-23) was an Cygnus-class cargo ship acquired by the U.S. Navy for service in World War II. She was responsible for delivering necessary goods and equipment to ships and stations in the war zone.

World War II Pacific Theatre operations

After sailing in convoy to Pearl Harbor and back between 4 September and 24 September 1942, Cygnus cleared San Francisco, California, 10 October and arrived in Auckland, New Zealand, 3 November. Until 5 January 1944 she operated on a regular run carrying chilled meats and vegetables from Auckland to the American bases at Tongatapu, Tonga Islands; Pago Pago, American Samoa; Bora Bora, Society Islands; Cook Island; and Funafuti, Ellice Islands. Between 18 January 1944 and 9 September 1945 she sailed on similar duty from Auckland and Napier, New Zealand, to Espiritu Santo and Efate, New Hebrides, the Solomon Islands; and Noumea, New Caledonia.

End-of-war activity

After a west coast overhaul, Cygnus sailed via Pearl Harbor to discharge cargo at Okinawa in December 1945. Arriving at Manus, Admiralty Islands, 3 January 1946, she operated out of this port on cargo duty to Noumea, Espiritu Santo, and American Samoa until 13 March when she returned to the U.S. West Coast and then sailed for New York, arriving 2 July.
