It was announced by the Pentagon on 8 January 2015 that RAF Alconbury and RAF Molesworth would be closing by 2020. Most of the units at Alconbury and Molesworth will be moved to RAF Croughton, along with the personnel.[5]

However, changing security conditions in Europe and resurgent politico-military moves by Russia have caused USEUCOM to begin reconsidering these closure actions in 2017 and actual closures remain in flux.[6]
