US tankers leave UK’s Mildenhall airbase over threat from Iran
US refuelling tankers have been moved from the British airbase Mildenhall following an Iran-related threat, the Wall Street Journal reported. The departures bring a second British airbase into focus after Washington withdrew bombers from RAF Fairford.
The WSJ reported that security at Mildenhall and Lakenheath had risen to FPCON Charlie, the second-highest US force-protection level. Officials were still assessing the precise nature of the reported threat.
Two tankers diverted to Germany on Monday, 9 November, with several more subsequently relocated to Germany and other destinations, according to Reuters.
A US official separately confirmed to The War Zone that enhanced security measures were in force at Mildenhall and nearby RAF Lakenheath but stopped short of identifying the rationale behind that.
Over the past couple hours flight tracking has shown unusual movements of many US airforce tankers out of RAF Mildenhall in quick succession. Experts note the activity is highly unusual for so many tankers to be leaving in such a short time. https://t.co/sP4vcLfebK

The British Ministry of Defence stated that aircraft move as per operational requirements. The US Air Force also cited routine rotations without confirming whether the tanker relocations were in response to Iran. Meanwhile, the Iranian ambassador has denied his country’s involvement in a plot against Fairford.

RAF Mildenhall in Suffolk hosts the 100th Air Refueling Wing, which operates KC-135 aircraft supporting US and allied operations across Europe and Africa. The tankers refuel aircraft in flight, helping them travel farther and remain airborne longer.
US B-1 bombers returned home from RAF Fairford in early October after a security incident near the base, The War Zone reported.
