In 1993, after two years of non-operational status, the 509th became operational again. On 1 March 1993, the wing activated the 509th Operations Group as part of the 509th Bomb Wing's reorganization under the USAF Objective Wing plan. All flying squadrons, as well as an Operational Support Squadron (OSS) were assigned to the 509th OG. The wing grew larger on 1 July 1993, when it accepted host responsibilities for Whiteman from the 351st Missile Wing. Its 509th OG received the first operational B-2 Spirit stealth bomber on 17 December 1993 (the date was the 49th anniversary of the activation of the 509th Composite Group and the 90th of the Wright brothers' flight).
