The Radioplane Q-1 was an American

anti-radar missile
.

Design and development

Shortly after its formation in 1948, the United States Air Force issued a specification calling for a new type of high-speed target drone. Required to be jet-powered to provide the most realistic training, the contract for the development of the drone was given to the Radioplane Company, later a division of Northrop.[1]

Powered by a single

vertical stabiliser, the design was modified to a twin tail configuration to provide additional clearance of its carrier aircraft.[1] Recovery, following the conclusion of the drone's flight, was by parachute.[1]

Operational history

The first flight of the XQ-1 prototype took place in 1950; 28 aircraft of the type were built.

Continental YJ69 turbojet replacing the pulsejet, becoming the XQ-1A;[1] however it was determined that further improvements were needed, and so a major redesign of the type was undertaken.[1]

Known by the company as RP-50 and designated by the USAF as YQ-1B, the revised drone flew for the first time during 1953, being evaluated by the Air Force later that year. Using the YJ69 engine, the air intake for the jet was relocated to the nose of the aircraft, while the airframe overall was modified to increase the streamlining of the craft.[1] The rocket-sled launch was abandoned in favor of air launching, with the Douglas DB-26 being the most common carrier aircraft.[1]

Six YQ-1Bs were built for evaluation; they proved trouble-free, no production order for the type was undertaken, the competing

anti-radar missile, which would be tested by the U.S. Air Force as the GAM-67 Crossbow.[3]

Variants

XQ-1
Initial pulsejet-powered prototype with single tail; later refitted with twin tails. 28 built.[1]
XQ-1A
Turbojet-powered version. One modified from XQ-1.[1]
YQ-1B
Definitive turbojet-powered version, six built.[1]
XQ-3
Variant planned to be constructed of fiberglass, none built.[1]
