Boeing X-45A Unmanned Aircraft Demonstrates Autonomous Capability

Boeing X-45A Unmanned Aircraft Demonstrates Autonomous Capability

Saint Louis, Missouri -- (Boeing) June 24, 2005 -- A Boeing [NYSE: BA] X-45A unmanned aircraft completed its 52nd flight recently, demonstrating its ability to adapt to a realistic and changing wartime operational environment.

Boeing X-45C Full-Scale Model Making Debut at Farnborough. A glimpse into the future was unveiled when the Boeing Joint Unmanned Combat Air Systems (J-UCAS) X-45C full-scale model made its debut at the Farnborough International Air Show on July 19, 2004. The model represents what the X-45C will look like when completed at the company’s St. Louis manufacturing facility in 2006. Assembly of this revolutionary aircraft began in June and it is scheduled to make its first flight in 2007. Boeing previously built two X-45A vehicles, now being flight-tested at Edwards Air Force Base, Calif. The X-45C is 39 feet long with a 49-foot wingspan and cruises at 0.80 Mach. It will carry eight Small Diameter Bombs (SDBs), Boeing’s newest near-precision, 250-pound weapon, or the full range of Boeing’s Joint Direct Attack Munitions(JDAMs). The J-UCAS X-45 program is a Defense Advanced Research Projects Agency/U.S. Air Force/U.S. Navy/Boeing effort to demonstrate the technical feasibility, military utility and operational value of an unmanned air combat system for both the Air Force and the Navy. Operational missions for the services may include suppression of enemy air defenses; strike; electronic attack; and intelligence, surveillance and reconnaissance. Boeing Photo.

During the test flight, a Joint Unmanned Combat Air Systems (J-UCAS) X-45A departed from NASA’s Dryden Flight Research Center, Edwards Air Force Base, Calif., climbed to 29,000 ft. and entered the base’s test range. While flying the mission, several simulated Surface-to-Air Missile (SAM) emitters were activated and the unmanned aircraft autonomously created its own flight plan to remain out of lethal range of the simulated SAM sites. Always managed by the pilot-operator, the X-45A then attacked its simulated priority ground target and showcased the ability to suppress enemy air defenses. Once the aircraft had conducted a simulated battle damage assessment, the X-45A safely returned to Edwards.

“The X-45A proved it could autonomously react to a dynamic threat environment while engaging a priority target,” said David Koopersmith, Boeing J-UCAS X-45 vice president and program manager. “Onboard planning and decision capabilities like these will make our next unmanned system, the X-45C, a highly survivable platform for the warfighter.”

The first X-45C will be completed in 2006, with flight-testing scheduled to begin in 2007. It will be 39 feet long with a 49-foot wingspan, cruise at 0.80 Mach at an altitude of 40,000 feet, carry a 4,500 pound weapon payload, and be able to fly a combat radius of more than 1,200 nautical miles. The software used and tested on the X-45A may be offered as a candidate for functionality in the development of the J-UCAS Common Operating System.

Boeing began its unmanned combat aircraft program in 1998. The following year, the Defense Advanced Research Projects Agency (DARPA) and the U.S. Air Force chose Boeing to build two X-45A air vehicles and a mission control station under the J-UCAS Advanced Technology Demonstration Program.

Winner of a 2005 Flight International Aerospace Industry Award, the J-UCAS X-45 program is a Boeing/DARPA/Air Force/Navy effort to demonstrate the technical feasibility, military utility and operational value of an unmanned air combat system for the Air Force and the Navy. Operational missions for the services may include persistent strike; penetrating electronic attack; suppression of enemy air defenses; and intelligence, surveillance and reconnaissance.
