According to a source familiar with the development, the aircraft were transferred from RAF Mildenhall in Suffolk, England, to an undisclosed military base in Germany as a precautionary measure against potential threats.
The move comes amid growing security concerns surrounding American military assets in Europe and continuing tensions between Washington and Tehran.
In response to the reported threat, American military authorities increased security at RAF Mildenhall and RAF Lakenheath to Force Protection Condition Charlie, also known as FPCON Charlie.
The designation represents a heightened security posture used when intelligence indicates an increased threat of hostile activity or when an incident has occurred that could affect military personnel or installations.
The elevated alert level typically involves additional security precautions, including tighter access controls, increased surveillance and enhanced protection of military equipment and personnel.
A US official confirmed to ABC News that the military was taking precautionary measures to safeguard its aircraft, personnel and facilities.
However, officials declined to disclose the specific nature of the Iranian threat or provide details about the intelligence that prompted the relocation.
The US Air Force acknowledged that military aircraft frequently move between bases and operational locations for various reasons, including training exercises and active mission requirements.
In a statement, an Air Force spokesperson explained that such movements are carried out in coordination with allied and partner nations under established military agreements covering access to air bases and airspace.
The spokesperson declined to provide additional information regarding the aircraft relocation, citing operational security concerns.
The Wall Street Journal was the first to report that the aircraft movement was connected to an Iranian threat, while military news outlet The War Zone initially reported the increased security alert levels at the two British bases.
RAF Mildenhall and RAF Lakenheath are strategically important installations supporting American military operations in Europe and beyond.
Mildenhall serves as a major hub for US Air Force refueling aircraft and other operational missions, while Lakenheath hosts American fighter aircraft and plays a significant role in regional defense activities.
The decision to reposition refueling tankers highlights the military’s efforts to reduce potential vulnerabilities and maintain operational readiness amid an uncertain security environment.
Although US officials have not publicly identified the precise threat or confirmed whether the aircraft could return to Britain soon, the elevated security measures indicate that authorities are treating the situation seriously.
For now, the relocation and heightened alerts underscore Washington’s continued focus on protecting American forces and military infrastructure as tensions with Iran remain a major security concern.
