The US operates from more than a dozen military bases in the UK.
The US Air Force's main bases in the UK are: RAF Lakenheath in Suffolk - home to the 48th Fighter Wing operating F-15 and F-35 jets; RAF Mildenhall in Suffolk - mainly a base for US air refuelling tankers; RAF Fairford in Gloucestershire - a large airbase which periodically hosts US Air Force long range bombers including B-52s, B1 and B2s.
RAF Fairford has recently been used by the US Air Force to carry out strikes on Iran, following a decision by the UK Government in March to allow the Trump administration to conduct so-called “defensive operations” against Iranian military targets.
It’s been reported the threat alert at RAF Fairford has recently been raised to Delta - the highest level, meaning there’s intelligence relating to an imminent potential attack.
The threat level at RAF Lakenheath and Mildenhall is believed to have been raised to Charlie - the second highest level when intelligence suggests there could be a potential attack.
