post-Cold War process that would later become known as Base Realignment and Closure or BRAC. Although Mather AFB's navigator training mission would relocate to Randolph AFB, Texas, the Mather B-52G bomber/KC-135A tanker wing would inactivate and the AFRES KC-135 tanker group would relocate to nearby McClellan AFB, relocating again four years later to Beale AFB when another BRAC process would close McClellan AFB. Concurrently, the Pease AFB bomber/tanker wing would lose its FB-111 aircraft and transfer to Whiteman AFB, Missouri in preparation for transition to the B-2 Spirit while a portion of Pease would be transferred to the New Hampshire Air National Guard for its ANG KC-135 air refueling wing and be renamed Pease Air National Guard Base. Additional closures and divestments of SAC bases would continue throughout the late 1980s and early 1990s, accelerating even more so as a result the START I Treaty's mandated elimination of both the entire B-52G fleet and the inactivation of all Minuteman II and Peacekeeper ICBMs, as well as the 1992 reorganization of the Air Force that disestablished SAC and dispersed its assets to other new or existing MAJCOMs, primarily ACC and AMC. In addition to closures of Mather AFB and Pease AFB, this would eventually include the following subsequent closure and realignment actions, primarily due to BRAC: Altus AFB (tenant SAC presence disestablished and transferred to AMC, later AETC) Barksdale AFB (transferred to ACC, now AFGSC) Beale AFB (transferred to ACC) Carswell AFB (transferred to USN as NAS JRB Fort Worth per BRAC) AFRES (later AFRC) HQ 10th Air Force, an ACC-gained AF Reserve fighter wing, and an AMC-gained ANG airlift wing remain Castle AFB (closed by BRAC) Dyess AFB (transferred to ACC, now AFGSC) Eaker AFB (closed by BRAC) Ellsworth AFB (transferred to ACC, now AFGSC) Fairchild AFB (transferred to AMC) F. E. Warren AFB (transferred to ACC, then AFSPC, now AFGSC) Grand Forks AFB (transferred to AMC, now ACC) Griffiss AFB (closed by BRAC) AFMC Rome Air Development Center and ANG Northeast Air Defense Sector HQ remain Grissom AFB (transferred to AFRC as Grissom ARB) K. I. Sawyer AFB (closed by BRAC) Loring AFB (closed by BRAC) Malmstrom AFB (transferred to AMC, then AFSPC, now AFGSC) March AFB (transferred to AFRC as March ARB per BRAC) McConnell AFB (transferred to AMC) Minot AFB (transferred to ACC, now AFGSC) Offutt AFB (transferred to ACC) Plattsburgh AFB (closed by BRAC) Robins AFB
