never confirmed or acknowledged by the U.S. military. BRAC 2005 In its 2005 Base Realignment and Closure (BRAC) Recommendations, DoD recommended to realign Grand Forks Air Force Base, North Dakota. It would distribute the 319th Air Refueling Wing's KC-135R aircraft to the 6th Air Mobility Wing (6 AMW) at MacDill AFB, FL (four aircraft) and several other installations, increasing the number of KC-135R aircraft assigned to the 6 AMW from twelve to sixteen aircraft . Concurrent with this BRAC decision, the 6 AMW would also host a Reserve association with the Air Mobility Command-gained 927th Air Refueling Wing (927 ARW) of the Air Force Reserve Command (AFRC), the latter of which would be realigned and relocated from Selfridge ANGB, Michigan to MacDill AFB. Under the Reserve Associate arrangement, both the 6 AMW and the 927 ARW would share the same KC-135R aircraft, while the 927 ARW would turn over their KC-135R aircraft to the 127th Wing (127 WG) of the Michigan Air National Guard at Selfridge ANGB. The 927 ARW began relocation from Selfridge ANGB to MacDill AFB in 2007 and formally established itself at MacDill in April 2008. Additional KC-135 Aircraft for 6 AMW / 927 ARW Long range USAF plans in the 2015 defense budget called for MacDill AFB to add eight additional KC-135R aircraft to its extant sixteen KC-135Rs in FY2018. The 6 AMW would also increase manning by approximately 300 personnel. These additional KC-135R aircraft would come from other Air Force, Air Force Reserve Command and Air National Guard units transitioning to the KC-46A Pegasus aerial refueling aircraft and the timeline would be contingent on those other units completing their transition and achieving operational capability with the KC-46. Departure of NOAA Aircraft Operations Center Until mid-2017, MacDill AFB also hosted the Aircraft Operations Center (AOC) of the National Oceanic and Atmospheric Administration (NOAA). Commissioned officers of the NOAA Corps and NOAA civil servants fly "Hurricane Hunter" missions in NOAA's WP-3D Orion and Gulfstream IV aircraft, as well as other research missions in these and other assigned fixed-wing and rotary-wing aircraft. With the anticipated increase in KC-135R aircraft and the need for additional maintenance hangar space, the Air Force informed NOAA in 2016 that they would no longer be able to host the NOAA Aircraft Operations Center, its aircraft, and the 110 NOAA personnel in Hangar 5 and its adjacent operations building at MacDill AFB.
