Boeing has test-flown a strike UAV that can be dropped from a supersonic F/A-22
Small, Lethal and Persistent
The U.S. Air Force wants to field a 100-lb. unmanned aircraft--launched from a stealth fighter flying at supersonic speed--that can cruise the battlefield for a half-day or more armed with a weapon powerful enough to disable a moving armored vehicle.
The project is called Air Dominator, and Boeing's Phantom Works has won the airframe technology demonstration phase of the project to build a low-speed, high-endurance candidate aircraft. The project is under the direction of the Air Force Research Laboratory at Eglin AFB, Fla.
As part of the project, Boeing also will look at an aerial refueling vehicle and a network "gateway" unmanned aircraft. Both, in company with the armed vehicles, would be part of a small interactive constellation of aircraft that would be launched in a cluster from a single F/A-22.
Although the five-year program has just started, Boeing has already flown the first prototype twice. It is a 4-ft.-long, 12-ft.-wingspan aircraft that uses advanced wing-warping techniques for flight control. That means the wing bends to turn the aircraft rather than using conventional flaps, ailerons and elevators. More flights will be made over the next year with an advance version of the miniature aircraft in a company-funded initiative.
The mature demonstrator aircraft is scheduled for first flight in 2005, said Carl Avila, Phantom Works' director of advanced tactical missile systems. The project is part of the persistent area dominance initiative being directed by the Air Force.
The concept of operations involves first defining a kill box or area of influence over which a number of flying munitions would scan the battlefield for a minimum of 12 hr.
"Those munitions would loiter there, and anything that enters that area, if it's a hostile target, would be attacked," Avila said. "The concept we proposed would loiter up to 48 hr."
