Aircraft of this type have no onboard human pilot.[5] As the operator runs the vehicle from a remote terminal, equipment necessary for a human pilot is not needed, resulting in a lower weight and a smaller size than a manned aircraft. Many countries have operational domestic UCAVs, and many more have imported fighter drones or are in the process of developing them.[6]
