Watchkeeper is an unmanned aerial vehicle (UAV) for all weather, Intelligence, Surveillance, Target Acquisition and Reconnaissance (ISTAR). Watchkeeper provides enhanced UAV capability that will enable commanders to detect and track targets for long periods, without the need to deploy troops into potentially sensitive or dangerous areas. The system is capable of rapid deployment and operations anywhere in the world and will support the information requirements of all three services.）
