On 1 June 1992, as part of the first major reorganization since the creation of USAF, the Air Force inactivated Strategic Air Command and assigned Ellsworth's organizations (including a renamed 28th Bomb Wing (28 BW)) to the newly activated Air Combat Command (ACC). After less than a year under the new command, the 28th's mission changed from that of strategic bombardment to one of worldwide conventional munitions delivery. The mission of the 99th Tactics and Training Wing (later to become the 99th Wing) also continued, albeit slightly modified to fit the requirements of the new force concept.
