The Ryan Firebee is a series of target drones developed by the Ryan Aeronautical Company beginning in 1951. It was one of the first jet-propelled drones, and remains one of the most widely used target drones ever built.
The Firebee I was the result of a 1948 U.S. Air Force request and contract to Ryan for a jet-powered gunnery target. The first flight of the XQ-2 Firebee prototype took place in early 1951. The drone featured swept flight surfaces and a circular nose inlet. The initial models had distinctive "arrowhead" shaped end plates on the tailplane. The Firebee could be air-launched from a specially modified launch aircraft (Douglas A-26 Invader was first to be used for this), or ground-launched with a single RATO booster.
