The USS Arctic (AF-7) was an Arctic-class stores ship built for the United States Navy, originally constructed as the steel-hulled freighter Yamhill in 1919 by Moore Shipbuilding Co. in Oakland, California. Acquired by the Navy on 4 November 1921 and commissioned at the New York Navy Yard on 7 November 1921, she was renamed Arctic (AF-7). The vessel was designed to serve as a supply ship, primarily delivering provisions such as food and household items to fleet units and naval stations in the Pacific. Arctic’s service was predominantly concentrated in the Pacific Ocean, where she operated chiefly with the fleet's train, supporting the Battle Fleet and various naval bases. Her routine involved annual voyages along the U.S. West Coast, including San Diego, San Pedro, San Francisco, Portland, and Seattle, along with trips to Hawaiian waters. During her pre-World War II service, she participated in a notable Australasian cruise to New Zealand and Samoa in 1925, accompanying the fleet. With the outbreak of World War II, Arctic’s activity increased significantly. She operated between Pearl Harbor and San Francisco, and in 1942, she saw deployment to Alaskan waters, supplying ships and shore facilities at Kodiak. Subsequently, she was assigned to the South Pacific, making supply runs to strategic locations such as Nouméa, Espiritu Santo, Efate, and Samoa. In 1944, Arctic was part of Service Squadron 8, conducting multiple voyages to the Marshall Islands, Ulithi, Palau Islands, and Iwo Jima, providing essential provisions to fleet units and shore installations amid ongoing combat operations. Later, she supported operations at Okinawa and provisioned fleet units off Yokosuka after Japan's surrender. Her service included sinking a mine with gunfire en route to Tokyo and Yokosuka. The vessel’s extensive wartime service made her a vital logistical asset in the Pacific Theater. Decommissioned on 3 April 1946 due to material defects, Arctic was struck from the Naval Vessel Register on 1 May 1946 and sold for scrap in 1947. Her service history underscores her maritime significance as a reliable supply vessel supporting U.S. naval operations throughout World War I, the interwar period, and especially during World War II in the Pacific.
