In 1988, Congressman Ike Skelton (D-MO) announced the B-2 Advanced Technology Bomber would be based at Whiteman AFB, Missouri. It was also announced that the 509th Bombardment Wing would become the USAF's first B-2 Spirit active-duty wing. Military personnel began leaving Pease in June 1990, and on 30 September 1990, the 509th was inactivated at Pease and activated at Whiteman Air Force Base as a non-operational unit the same day without aircraft, personnel or equipment. With the reassignment the unit was redesignated as the 509th Bombardment Wing, Heavy. On 1 June 1992, the Air Force disestablished the Strategic Air Command (SAC), transferring all bomber aircraft to the newly established Air Combat Command (ACC). The 509th was redesignated the 509th Bomb Wing on 1 September 1991, and became part of the new Air Combat Command on 1 June 1992.
