 The Pegasus was rolled out on 30 July 2001 and performed its first flight on 23 February 2003 at the US Naval Air Warfare Center at China Lake, California.Both the Air Force and the Navy had been developing plans for operational follow-ons to their respective demonstrator programs, but pressures rose for the two services to merge their efforts, resulting in the formation of the "Joint Unmanned Combat Air System (J-UCAS)" program in October 2003 under DARPA direction.Of course, the candidates for the J-UCAS program include follow-ons to the X-45A and the X-47A.
