"RAF" Alconbury in Huntingdon, England is a non-flying facility, under the control of the United States Air Force.
It was announced by the Pentagon on 8 January 2015 that RAF Alconbury and RAF Molesworth would be closing by 2020 (although some current estimates are more like 2022). The intention seems to be to move most of the missions at Alconbury and Molesworth to "RAF" Croughton, along with the personnel.
