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.

It was also awarded the Distinguished Unit Citation and several campaign streamers.
