The USS Kanawha (AO-1) was the first purpose-built fleet oiler of the United States Navy and the lead ship of her class. Constructed at Mare Island Navy Yard, Vallejo, California, she was laid down on December 8, 1913, launched on July 11, 1914, and commissioned on June 5, 1915. The vessel measured approximately 500 feet in length with a beam of around 66 feet, designed to carry fuel oil and gasoline to support naval operations. During her early service, the Kanawha operated primarily along the Atlantic coast, making multiple trips to Port Arthur, Texas, for fuel supplies, and participated in tactical exercises, mail delivery, and target towing. After the U.S. entered World War I, she was assigned to the Atlantic Fleet and served as an escort for the first American Expeditionary Force convoy to France, arriving at St. Nazaire in July 1917. Throughout the war, she actively supplied fuel to cruiser forces and convoyed vessels across the Atlantic, including voyages from Halifax to U.K. and French ports under the Naval Overseas Transportation Service. Post-war, Kanawha transitioned to operations in the Pacific, operating along the West Coast, Hawaii, and the Panama Canal Zone. She participated in the Army-Navy maneuvers in Hawaii in 1925 and joined a goodwill cruise to Australia and New Zealand. After decommissioning in December 1929, she was recommissioned in June 1934 and continued coastal and offshore fueling missions, extending her reach as far north as Alaska and as far east as Midway and Wake Islands. During World War II, USS Kanawha resumed her vital role in fueling Pacific fleet operations. She supported ships engaged in the Solomon Islands campaign until her sinking in April 1943. While anchored at Tulagi harbor, she was attacked by Japanese aircraft, resulting in fires from bomb hits and ammunition explosions. Efforts to rescue and extinguish fires failed, and she was beached and subsequently sank before dawn on April 8, 1943. Her service earned her one battle star, and her sinking marked a significant loss in her vital support role during the Pacific War.
