on 12 March 1993 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 first B-2 Spirit stealth bomber arrived and was assigned to the 509th 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). On 17 September 1996, three 509th B-2s dropped three inert GBU-36 weapons, the highly accurate Global Positioning System-Aided Munitions (GAM) which used the GPS-Aided Targeting System (GATS). The B-2s made the drops at the Nellis AFB, Nevada, bombing range. Range officials, inspecting the area after the releases, were astonished to find that the GBU-36s had fallen seven, four, and four feet, respectively, from the target. A month later, the 509th repeated this impressive feat—only this time, they used live weapons. On 8 October 1996, three B-2s revisited the Nellis range and released 16 2,000 lb. class GBU-36 bombs from an altitude of 40,000 feet. Again, amazed range personnel discovered all sixteen projectiles hit close enough to their targets to be confirmed as 16 kills. The results so impressed USAF Chief of Staff General Ronald Fogleman that he announced at a mid-December press conference the 509th and the B-2 would reach limited (conventional) operational capability on 1 January 1997. Operation Allied Force The B-2 first saw combat 23 March 1999, during NATO operations in Serbia and Kosovo, the first sustained offensive combat air offensive conducted solely from U.S. soil. Over a period of two months, the 509th generated 49 B-2 sorties flown roundtrip from Missouri to targets in Southeastern Europe. Although the B-2s accounted for only 1 percent of all NATO sorties, the aircraft's all-weather, precision capability allowed it to deliver 11 percent of the munitions used in the air campaign. The missions lasted an average of 29 hours, demonstrating the global reach of the B-2. On the night of 7–8 May 1999, during the Kosovo War B-2s flying out of Whiteman attacked the Belgrade embassy of the People's Republic of China, killing three and causing heavy damage. Although a strike was authorized against a target called 'Belgrade Warehouse 1', the CIA-provided coordinates pinpointed the embassy's location. Neither the aircrew nor the US Air Force were found to have any responsibility for the affair. Operation Enduring Freedom
