The Ryan Firebee was a series of target drones developed by the Ryan Aeronautical Company beginning in 1951. It was one of the first jet-propelled drones, and one of the most widely used target drones ever built.
The Firebee I was the result of a 1948 US 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 endplates on the tailplane. The Firebee could be air-launched, specially modified Douglas A-26 Invader bombers being first used for this, or ground-launched with a single RATO booster.
Following successful evaluation, the target was ordered into production for the USAF as the Q-2A, powered by a Continental J69-T-19B turbojet engine, with 1,060 pounds-force (4.7 kN) of thrust. The Air Force then obtained small numbers of a Q-2B with a more powerful engine for high-altitude performance.
The US Navy bought the Firebee as the KDA-1, with much the same appearance as the Q-2A, differing mainly in that the powerplant was a Fairchild J44-R-20B turbojet, with 1,000 lbf (4.4 kN) thrust. The KDA-1 could be distinguished from the Q-2A from the fact that the KDA-1 had an inlet centerbody. The US Army also obtained a version designated the XM21 that differed from the KDA-1 only in minor details.
The Navy obtained several improved variants of the KDA-1, including the XKDA-2 and XKDA-3, which were not built in quantity, and the KDA-4, which was the main production version for the series. These variants were hard to distinguish from the KDA-1, differing mainly in successively uprated J44 engines and minor changes.
In the late 1950s, the USAF awarded Ryan a contract for a substantially improved "second generation" Firebee, the Model 124, originally with the designation Q-2C. The initial prototype performed its first flight in late 1958 and went into production in 1960. In 1963, it was redesignated the BQM-34A.
