The GAM-67 Crossbow was a jet-powered anti-radar missile built by Northrop's Ventura Division (successor to the Radioplane Company).

Development[edit]

In the late 1940s, the Radioplane Company developed a set of prototypes of the Q-1 target series, which used pulsejet or small turbojet engines. Although the Q-1 series was not put into production as a target, it did evolve into the USAF RP-54D / XB-67 / XGAM-67 Crossbow anti-radar missile, which was first flown in 1956. It was also considered as a platform for reconnaissance, electronic countermeasures, and decoy roles.

The Crossbow had a cigar-shaped fuselage, straight wings, a straight twin-fin tail, and an engine inlet under the belly. It was powered by a Continental J69 turbojet engine, with 4.41 kN (450 kgf/1,000 lbf) thrust. Two Crossbows could be carried by a Boeing B-50 Superfortress bomber, while four Crossbows could be carried by a Boeing B-47 Stratojet bomber.

Only 14 Crossbows were built before the program was cancelled in 1957, in favor of a more sophisticated system that ended up being cancelled in turn. However, it did point the way to the range of missions that would be performed by UAVs in later decades.
