The USS Tappahannock (AO-43) was a Kennebec-class oiler constructed during World War II, originally laid down as the SS Jorkay, a T2-A tanker, under a Maritime Commission contract (MC hull 157). Built by the Sun Shipbuilding & Drydock Co. in Chester, Pennsylvania, she was launched on 18 April 1942 and acquired by the Navy on 29 May 1942. After conversion at the Philadelphia Navy Yard, she was commissioned on 22 June 1942 and designated AO-43, the only U.S. Navy ship bearing the name derived from the Rappahannock River in Virginia. The Tappahannock's early service saw her operating across the South Pacific, supplying fuel and supplies to Allied ships during key campaigns in the Solomon Islands, Guadalcanal, and others. Notably, she participated in the Battle of Guadalcanal, surviving Japanese air attacks, including a dive-bomber raid in April 1943, which damaged her radar and hull but did not incapacitate her. Throughout World War II, she served as a vital station and underway replenishment ship, supporting operations from the Gilbert Islands to Okinawa, and aiding in the occupation of Japanese-held territories after the war. Her duties included fueling fleet units, serving as a station tanker, and supporting carrier raids, earning nine battle stars for her wartime service. Post-World War II, Tappahannock operated in the Far East, China, and the Mediterranean, supporting occupation and logistical operations. She was transferred to the Military Sea Transportation Service (MSTS) in 1949, and after decommissioning in 1950, she was recommissioned in 1950 amid the Korean War buildup. She served in Atlantic and European waters before decommissioning again in 1955. Reactivated in 1956, she operated across the Caribbean, Mediterranean, and Arctic Circle, supporting NATO and other operations. Recommissioned in 1966, Tappahannock saw extensive service during the Vietnam War, supporting the 7th Fleet's Yankee Station and Market Time interdiction operations off Vietnam. Her duties included underway replenishments, delivering millions of gallons of fuel, and supporting combatant ships in a hazardous environment. Despite her age, she remained a key logistical asset until her final deployment in 1969. Decommissioned in 1970, she was struck from the Navy List in 1976 and scrapped in 1987. Throughout her career, USS Tappahannock earned nine battle stars for World War II and nine for Vietnam, marking her as a distinguished vessel in U.S. naval logistics and operational history.
