The Watchkeeper drone is an autonomous aircraft, which the British army says can be fitted with radar sensitive enough to detect footprints left in the dirt.
The UK’s Ministry of Defence (MoD) has bought drones of this type to provide forces with the ability to carry out surveillance, target acquisition and reconnaissance 24/7 in all weathers.
The MoD will use Watchkeeper as part of a system made up of unmanned air vehicles, sensors, data links and ground control stations.
The drone, a modified version of the Israeli Hermes 450 craft, was due to be deployed by the UK military in February this year.
