The United States military has relocated multiple aircraft, including two refuelling tankers, from the RAF Mildenhall airbase in eastern England to Germany and alternative destinations. According to reports citing sources familiar with the matter, the relocation was prompted by a threat from Iran.

US authorities elevated the security posture at both RAF Mildenhall and RAF Lakenheath to Force Protection Condition Charlie, which is the second-highest defensive level in the Department of Defense security system and signifies that a terrorist action is likely. While US officials continue to discuss the precise nature of the threat, representatives for the UK Ministry of Defence and the US Air Force noted that military assets and aircraft routinely move or rotate based on operational needs and standard procedures.

This deployment shift follows an incident weeks prior where five individuals were arrested outside the RAF Fairford airbase in southwest England, alongside two additional arrests suspected of assisting Iranian intelligence. That earlier security event led the US to withdraw B-1 bombers from RAF Fairford amid heightened regional tensions surrounding the ongoing US-Israel conflict with Iran. The Islamic Revolutionary Guard Corps previously stated that any installations used to launch attacks against Iran constitute legitimate targets, though Tehran's ambassador to the UK has denied involvement in plots against the airbases.
