Drones over the bases in Britain ranged in size and configuration, a U.S. Air Forces in Europe spokesperson said.
Unidentified drones have been seen over three air bases in Britain, which are used by the United States Air Force (USAF), last week, both countries have confirmed.
The USAF confirmed «small unmanned aerial systems» (UASs) were spotted flying above and in the vicinity of Royal Air Force bases in Lakenheath, Mildenhall, and Feltwell in eastern England between November 20 and 22, The Press Association news agency reported.
It is unclear at this stage if the drones spotted were considered hostile.
«The number of UASs fluctuated and they ranged in size/configuration», the USAF said in a statement. «The UASs were actively monitored and installation leaders determined that none of the incursions impacted base residents or critical infrastructure.
