USS Polaris (AF-11) was a Type C2 "Liberty fleet" standard freighter and an Aldebaran-class stores ship acquired from the United States Maritime Commission by the US Navy for World War II and the Korean War.

World War II North Atlantic operations

Polaris made five round trips from the U.S. East Coast to Reykjavík, Iceland from June 1942 to February 1943. She then made five voyages from the U.S. East Coast to Port of Spain, Trinidad, and San Juan, Puerto Rico, March to July 1943. From October 1943 to February 1944 she made four more voyages to the Caribbean, touching at Port of Spain, Trinidad; Guantanamo Bay, Cuba; Hamilton, Bermuda; the Virgin Islands; and San Juan, Puerto Rico.

From March through September 1944 Polaris made three round-trip voyages in convoy from the east coast to Oran, Algeria, and other Mediterranean ports. In October she made another voyage to the Caribbean.

Pacific Ocean deployments

On 10 November 1944 she departed New York for the Panama Canal Zone escorted by the USS Leland E. Thomas (DE-420) and arrived at Cristóbal, Colón 16 November 1944.^[2] Polaris then sailed to Enewetak, Saipan, Tinian, and Apra before returning to Seattle, Washington, 9 January 1945.

She was underway 16 January to Pearl Harbor, Eniwetok, and Ulithi. She returned to Los Angeles, California, 31 March and was underway again 13 April on a replenishment cruise to the Carolines and the Ryukyus, firing on Tokashiki Island in the Ryukyus 9 July, and returning to San Francisco 30 August.

Polaris served in the Korean War with Service Squadron 1 and made six cruises to Korean waters between 29 January 1951 and 23 July 1954.
