Unmanned Combat Air System Demonstrator program
The United States Navy Unmanned Combat Air System Demonstrator program included:
The UCAS-D program was created to demonstrate the feasibility of operating an Unmanned [aerial vehicle|unmanned aircraft] from an aircraft carrier. Technology and operational procedures developed through the program and the X-47B demonstrator informed the design of a future operational carrier-based unmanned aircraft under the Unmanned Carrier-Launched Surveillance and Strike (UCLASS) program. After debate over whether UCLASS should prioritize strike or surveillance, the Pentagon restructured the program into the Carrier-Based Aerial Refueling System. The CBARS program aimed to produce an unmanned aerial vehicle for aerial refueling to extend the range of manned fighters.
This project led to the development of the carrier-based aerial refueling drone, the Boeing MQ-25 Stingray.
