The 307th Operations Group (349 OG) is an Air Reserve Component (ARC) of the United States Air Force. It is assigned to the 307th Bomb Wing, Air Force Reserve Command, stationed at Barksdale Air Force Base, Louisiana.

In the postwar era, the 307th 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 307th Operations Group was activated on 8 January 2011. It's mission is strategic nuclear deterrence and global strike. The Air Force Reserve wing is a B-52 Stratofortress unit whose mission is to train B-52 pilots in initial qualification.
