The USS Polaris (AF-11) was an Aldebaran-class stores ship originally built as a Type C2 "Liberty fleet" standard freighter, launched in 1939 by Sun Shipbuilding & Drydock Co. in Chester, Pennsylvania. Designed to serve as a supply vessel, she was acquired by the U.S. Navy for use during World War II and the Korean War, playing a vital role in logistical support across multiple theaters. During World War II, Polaris conducted extensive service in both Atlantic and Pacific theaters. From June 1942 to February 1943, she completed five round trips from the U.S. East Coast to Reykjavík, Iceland. Subsequently, from March to July 1943, she made five voyages to Caribbean ports including Port of Spain, Trinidad, and San Juan, Puerto Rico. Between October 1943 and February 1944, she continued Caribbean operations, calling at Trinidad, Guantanamo Bay, Bermuda, the Virgin Islands, and Puerto Rico. From March through September 1944, Polaris undertook three convoy voyages from the U.S. East Coast to Mediterranean ports such as Oran, Algeria. In November 1944, she transited the Panama Canal to support operations in the Pacific, visiting Enewetak, Saipan, Tinian, and Apra before returning to Seattle in January 1945. In 1945, Polaris participated in replenishment cruises to Pearl Harbor, Eniwetok, and Ulithi, supporting operations in the Pacific Theater, including firing on Tokashiki Island in the Ryukyus. After the war, she served in Japanese waters and along the China coast before being decommissioned on 18 January 1946 and struck from the Naval Vessel Register shortly thereafter. Reactivated for the Korean War, Polaris served with Service Squadron 1, making six voyages to Korean waters between 1951 and 1954. Notably, she set a record for her class by transferring 116.10 tons of provisions per hour during underway replenishment to the USS Midway in April 1955. She was struck from the Naval Vessel Register in October 1957 and transferred to the Maritime Administration. By 1970, she was part of the National Defense Reserve Fleet in Suisun Bay, California, marking a distinguished career as a vital logistical support vessel for U.S. naval operations across multiple conflicts.
