The 307th Air Refueling Group is an inactive United States Air Force unit. It was last assigned to the 47th Air Division, stationed at Travis Air Force Base, California. It was inactivated on 31 December 1983
Two Presidential Unit Citations were awarded to the Group during World War II, one for action in the bombing of the Island of Truk, the most heavily defended and strongly fortified Japanese base in the Pacific. During withdrawal. gunners of the Group destroyed 31 of the 75 attacking aircraft, probably destroyed 12 more and damaged 10 in an air battle that lasted 43 minutes. This daring raid, made on 29 March 1944, neutralized the Japanese airfields, making possible long range flights without fighter protection, The other Presidential Unit Citation was awarded for the successful strike at the Baltkapapan Oil Refineries in Borneo on 30 September 1944. The 307th had to fly their B-24 Liberator bombers 17 1/2 hours for a round trip of 2,610 miles, the longest mass daylight mission ever flown by this type aircraft.
In the postwar era, the 93d Bombardment Group was one of the USAAF bombardment groups assigned to Strategic Air Command on 4 August 1946, the group being activated as a redesignation of the 498th Bombardment Group due to the Air Force's policy of retaining only low-numbered groups on active duty after the war.
The group deployed to Okinawa during the Korean War and was awarded the Republic of Korea Presidential Unit Citation for its air strikes against enemy forces in Korea. It was also awarded the Distinguished Unit Citation and several campaign streamers. The group was inactivated in 1952 when the parent wing adopted the Tri-Deputate organization and assigned all of the groups squadrons directly to the wing.
