Unmanned Aerial Vehicle (UAV)

Existing UAV systems
UAVs have been developed and deployed by many countries around the world. For a list of models by country. The use of unmanned aerial systems, however, is not limited to state powers: non-state actors can also build, buy and operate these combat vehicles. Hezbollah used a drone during the 2006 Lebanon War, and in 2001 Al-Qaeda reportedly explored using drones to attack a conference of international leaders.
The export of UAVs or technology capable of carrying a 500 kg payload at least 300 km is restricted in many countries by the Missile Technology Control Regime. At the center of the American military's continued UAV research is the MQ-X, which builds upon the capabilities of the Reaper and Predator drones. As currently conceived, the MQ-X would be a stealthier and faster fighter-plane sized UAV capable of any number of missions: high-performance surveillance; attack options, including retractable cannons and bomb or missile payloads; and cargo capacity.
China has exhibited some UAV designs, but its ability to operate them is limited by the lack of high endurance domestic engines, satellite infrastructure and operational experience.
