The Royal Saudi Air Force (RSAF) formally has unveiled its first CH-4 armed unmanned aerial vehicle in a ceremony celebrating the 50th anniversary of the King Faisal Air College in Riyadh.

The new CH-4 is an unmanned combat aerial vehicle developed by the China Academy of Aerospace Aerodynamics of China Aerospace Science and Technology Corporation (CASC). The CH-4 series of drones looks like a US MQ-9 Reaper developed by General Atomics.

CH-4 is capable of firing air-to-ground missile from altitude of 5,000 meters, therefore the aircraft can stay outside of effective range of most anti-aircraft guns. It also allow CH-4 to be able to fire from a position that provides wider viewing area.
