(tenant Regular AF SAC presence disestablished; base remains an AFMC installation with ACC and ACC-gained ANG flying wings) Seymour Johnson AFB (TAC base transferred to ACC; tenant SAC presence disestablished and SAC-gained tenant AF Reserve presence transferred to AFRC, now gained by AMC) Whiteman AFB (transferred to ACC, now AFGSC) Wurtsmith AFB (closed by BRAC) On 1 July 1989, the 1st Combat Evaluation Group reporting directly to SAC headquarters was split with most HQ 1CEVG organizations transferring to SAC HQ (e.g., the Command Instrument Flight Division) and RBS personnel, equipment, and radar stations becoming the 1st Electronic Combat Range Group. Airborne NEACP alerts ended in 1990 and during 1991's Operation Desert Storm to liberate Kuwait from Iraqi invasion and occupation, SAC bomber, tanker and reconnaissance aircraft flew operations (e.g., B-52s with conventional bombs and conventional warhead AGM-86 ALCMs) near Iraq from bases in Great Britain, Turkey, Cyprus, Diego Garcia, Saudi Arabia, and the United Arab Emirates. Following Operation Desert Storm, the dissolution of the Soviet Union and the de facto end of the Cold War, President George H. W. Bush and Secretary of Defense Dick Cheney directed SAC to take all bomber and refueling aircraft and Minuteman II ICBMs off of continuous nuclear alert on 27 September 1991 and placing said aircraft on quick reaction ground alert. The 31 May 1992 major reorganization of the USAF organizational structure subsequently disestablished SAC, moving its bomber, reconnaissance and aerial command post aircraft and all SAC ICBMs, along with all Tactical Air Command aircraft, to the newly established Air Combat Command (ACC). The newly established Air Mobility Command (AMC) inherited most of SAC's KC-135 Stratotanker aircraft and the entire KC-10 Extender aerial refueling tanker force, while some KC-135s were reassigned directly to USAFE and PACAF, with one additional air refueling wing assigned to the Air Education and Training Command (AETC) as the KC-135 formal training unit. Land-based ICBMs were later transferred from ACC to Air Force Space Command (AFSPC), while manned bombers remained in ACC. USAF nuclear forces in ACC and AFSPC were then combined with the United States Navy's Fleet Ballistic Missile submarine forces to form the United States Strategic Command (USSTRATCOM), which took over the SAC Headquarters complex at Offutt AFB. In 2009, the entire land-based USAF ICBM force and that portion of the USAF manned bomber force that was still nuclear-capable, e.g., the B-2 Spirit and B-52 Stratofortress, was transferred
