U.S. Air Force Relocates Aircraft from RAF Mildenhall Due to Security Threat

The U.S. Air Force has moved several aircraft from RAF Mildenhall in eastern England because of a security threat. Officials confirmed this decision on Tuesday. The Wall Street Journal reported that the threat originated in Iran.

As officials analyzed the threat, they elevated the base’s security to Force Protection Condition Charlie. This level suggests a likely terrorist threat against personnel or facilities.

According to flight-tracking data, 13 U.S. aircraft left RAF Mildenhall late Monday. Among these were nine Boeing KC-135 Stratotankers, relocated to airfields in Scotland, Germany, and Spain. Additionally, three CV-22B Ospreys were moved to RAF Lakenheath, which has reinforced aircraft shelters.

A U.S. official stated the relocations were precautionary. Some aircraft were on rotational deployments, while others were permanently stationed in the UK.

This event is the second major aircraft relocation from Britain in under two months. Earlier in October, bombers were removed from RAF Fairford following a thwarted attempt involving suspicious vans near the base.

Following the incident, two individuals faced charges under the UK’s National Security Act. Additionally, the U.S. Justice Department unveiled indictments against three individuals linked to terrorist plots, including one at RAF Fairford.

RAF Mildenhall hosts the 100th Air Refueling Wing, the sole U.S. tanker unit in Europe. Its KC-135 Stratotankers support missions like aerial refueling across the region.

U.S. Secretary of State Marco Rubio noted that repositioning forces globally is a routine activity. He mentioned this when pressed about the aircraft evacuation.

A spokesperson for 10 Downing Street confirmed that British air bases are secure. London and Washington continue to exchange intelligence on potential threats.
