The UK Royal Air Force (RAF) has hailed the Airborne Stand-Off Radar (ASTOR) system on the Sentinel R1 aircraft as a success after returning from trials in Afghanistan.
The aircraft is capable of operating for over nine hours at a time, during which it recognises and detects moving, static and fixed targets on the ground.
UK Minister for Defence, Equipment and Support, Quentin Davies said that the hugely sophisticated system successfully demonstrated what it could do in Afghanistan.
"The ASTOR system is a key element of the modern network-enabled battlefield, through which our forces can learn about the movement of enemy forces and react to prevent those threats to our troops," he said.
