After shakedown off the Gulf Coast, this mobile station tanker loaded a cargo of fuel oil at Corpus Christi, Texas; steamed through the Panama Canal; and joined the Third Fleet at Espiritu Santo on 5 April. She took on a deck cargo of lube oil drums which she discharged at Purvis Bay. Returning to Espiritu Santo, she then proceeded to Efate, New Hebrides, fueling Battleship Division 3 and Destroyer Division 90. Arriving at Purvis Bay 20 July, the ship assumed fueling station ship duties and made several side trips to the Russell Islands.
On 14 September, Raccoon proceeded to Samoa to load fuel oil, returning to Espiritu Santo and Purvis Bay for station duty. With the exception of a short trip to Bougainville, she remained at Purvis Bay until 6 February 1945, when she proceeded to the Russell Islands to fuel a task force of attack transports (APAs) and amphibious cargo ships (AKAs). Departing 21 March, Raccoon proceeded to Iwo Jima to fuel destroyers and destroyer escorts on patrol screen. On Easter Sunday, 1 April, she came under fire from Kamikaze aircraft. She arrived at Saipan on 14 June for harbor fueling duty which lasted through the end of the war and into April 1946. She then sailed from the Mariana Islands, transited the Panama Canal, and arrived Norfolk, Virginia, on 3 June. Raccoon decommissioned on 10 July, was redelivered to WSA the next day, and was stricken from the Naval Vessel Register on 31 July 1946.
