For the first time the Ministry of Defence and the RAF have opened up their drone operations to the media.
The BBC's defence correspondent Jonathan Beale went to RAF Waddington in Lincolnshire to see the latest unmanned aerial vehicles being used by the British military.
He has been speaking to Wing Cdr Damian Killeen, who is in charge of the squadron that flies the armed Reaper drones over Afghanistan.
