The US military reportedly evacuated aircraft from RAF Mildenhall, a second airbase in Britain, on Monday after a threat from Iran, according to a report citing people familiar with the matter.
The report said two US refuelling tankers operating from the base were diverted to Germany earlier on Monday.
Several other tankers stationed at Mildenhall were moved to Germany and other locations later in the day, the report said.
The move comes weeks after Washington withdrew its bombers from RAF Fairford over a suspected security incident linked to Iran.
