of New Georgia. She returned to San Francisco, in July 1943, and then made two trips from the west coast to Pearl Harbor. Cimarron departed Pearl Harbor 29 September 1943 with the force which raided Wake Island on 5–6 October, and returned to Pearl Harbor on 16 October. She sailed once again on 14 November to fuel in support of the Gilbert Islands campaign, returning 1 December, and sailed to San Pedro, California, to reload 12 December to 4 January 1944. Clearing Pearl Harbor on 13 January 1944, she supported the Marshall Islands operation and the February attacks on Truk from Majuro until 6 June; the Marianas operation from Eniwetok until 26 August; and the Palau Islands operation from Ulithi. After a stateside overhaul from October through December 1944, Cimarron arrived at Ulithi on 26 December 1944. From 27 December to 21 January 1945 she sailed to fuel the task force launching air attacks on Indo-China and Philippine targets as part of the Luzon invasion, and put to sea again from 8 February to 22 March for air raids on the Japanese home islands and the invasion of Iwo Jima. From 26 March to 23 May she sailed from Ulithi to fuel ships engaging in the Okinawa operation, and from 3 June shuttled between Ulithi and the areas from which the mighty carrier task forces launched the final series of raids upon the heartland of Japan. Ulithi remained her base as she supported the occupation until 10 September, when she anchored in Tokyo Bay. Operations in the Far East continued until 4 February 1946, when she arrived at Long Beach Naval Shipyard, for overhaul. Korean War Between July 1946 and June 1950, Cimarron ferried oil from the Persian Gulf to naval bases in the Marianas and Marshalls, occasionally continuing on to the US West Coast. Her first tour of duty in the Korean war, from 6 July 1950 to 3 June 1951, found her fueling ships of the Taiwan Patrol at Okinawa, amphibious ships at Kobe, and operating from Sasebo to the waters off Korea to fuel task forces. Several times she entered the heavily mined waters of Wonsan Harbor South Korea to fuel the ships carrying out the lengthy blockade and bombardment of that key port. Returning to the west coast, she gave service as a training tanker until her second Korean tour, from 1 August to 10 December
