drone
drone or remotely piloted vehicle, a pilotless craft guided by remote control. Aircraft, ships, and land vehicles can be designed or outfitted as drones, although underwater vessels—both piloted and pilotless—are usually called submersibles . Small, relatively inexpensive military drones are used as targets in combat practice, while high-performance models may be used in hazardous reconnaissance missions and to carry and launch missiles against enemy targets without exposing pilots and their far more expensive aircraft to antiaircraft fire. Depending on the mission, drones can be equipped with armament, radar, video cameras, lasers, or sensors for chemical or biological weapons. Guidance of the drone can originate from an airplane, a ship, a ground station, or a satellite link. Building upon the successful use of drones in the Second Persian Gulf War, the Homeland Security Department is planning to use unmanned aircraft to track drug smugglers, illegal immigrants, and terrorists along the U.S. borders. Contemplated civilian uses include replacing stationary video cameras and sensors for traffic control, for monitoring crops, to help fight forest fires, and for atmospheric research.
