The U.S. military diverted refueling tankers and transport aircraft from RAF Mildenhall in Suffolk on Monday, marking the second time American assets have redeployed from British bases in two months amid security concerns linked to Iran.
Flight tracking data verified by the press showed that 10 KC-135 Stratotanker refueling jets and three Osprey transport planes left the English base on Monday.
The refueling tankers headed to facilities in Germany, Spain, and Scotland. The Ospreys relocated to nearby RAF Lakenheath.

Four KC-135 Stratotankers landed at Spangdahlem Air Base and one arrived at Ramstein Air Base in Germany. Four additional tankers landed at Morón Air Base in southern Spain, and one went to Glasgow Prestwick Airport in Scotland, according to public aircraft tracking data confirmed by CBS News.
Security at both RAF Mildenhall and RAF Lakenheath was raised to Force Protection Condition Charlie (FPCON Charlie), which is the second-highest defensive threat level in the U.S. Department of Defense security system.

The U.S. military’s European Command declined to discuss specific asset movements or intelligence matters. A spokesperson said that the command takes proactive measures to ensure safety while working closely with host-nation allies.

“Aircraft and other assets move regularly according to operational requirements,” a U.S. Air Force spokesperson said.

The redeployment from Mildenhall follows a similar security incident at RAF Fairford in Gloucestershire, where the U.S. Air Force removed B-1 bombers in October following an investigation into an alleged, Iran-backed plot to target aircraft and military personnel.
British counterterrorism police were probing a ‘major’ incident near the base on September 28, and two men were subsequently charged with assisting Iranian intelligence in relation to the incident: Mohmed Abdulkarim, 24, and Nouman Essghir, 24.
