On November 1, 2005, management of the J-UCAS program transitioned to the new Joint Program Office headquartered at Wright-Patterson Air Force Base. This is the archived website developed by the DARPA J-UCAS office during its management of the program.

Joint Unmanned Combat Air Systems


The Joint Unmanned Combat Air Systems (J-UCAS) program is a joint DARPA/Air Force/Navy effort to demonstrate the technical feasibility, military utility and operational value for a networked system of high performance, weaponized unmanned air vehicles to effectively and affordably prosecute 21st century combat missions, including Suppression of Enemy Air Defenses (SEAD), surveillance, and precision strike within the emerging global command and control architecture.

The J-UCAS program combines the efforts that were previously known as the DARPA/USAF Unmanned Combat Air Vehicle (UCAV) and the DARPA/USN Naval Unmanned Combat Air Vehicle (UCAV-N) programs.
