Unidentified drones were spotted over three airbases in the UK this week, the US Air Force (USAF) has confirmed.
The incidents involved “small unmanned aerial systems” between 20 and 22 November over RAF Feltwell in Norfolk and Suffolk-based RAF Lakenheath and RAF Mildenhall.
It’s not clear if the drones were considered hostile, according to the USAF, which uses the bases.
The air force said it maintains the “right to protect” installations but didn’t say if any defence mechanisms were used.
“The number of UASs (unmanned aerial systems) fluctuated and they ranged in size/configuration,” the USAF said.
“The UASs were actively monitored and installation leaders determined that none of the incursions impacted base residents or critical infrastructure.
“To protect operational security, we do not discuss our specific force protection measures but retain the right to protect the installation.
“We continue to monitor our airspace and are working with host-nation authorities and mission partners to ensure the safety of base personnel, facilities and assets.”

“This includes counter drone security capabilities. We won’t comment further on security procedures.”
