The United States Air Force (USAF) has confirmed it will pull out of three UK airbases.
US Defence Secretary Chuck Hagel said the Americans will leave RAF Mildenhall in Suffolk and RAF Alconbury and RAF Molesworth in Cambridgeshire.
The move is part of a programme to save £320m ($500m) a year across Europe. The USAF lease the RAF bases.
Mr Hagel said he understood it would mean job losses and thanked those who had supported the US Air Force.
