The McDonnell LBD-1 Gargoyle (later KBD-1) was an American air-to-surface missile developed during World War Two. It was one of the precursors of modern anti-ship missiles.

Following German success with the Hs-293 and Fritz X, the U.S. began work on a series of similar weapons. These included Bat, Felix, GB-8, and Gargoyle.

Gargoyle had a 1000 pound (454 kg) warhead (M65 general purpose {GP} or M59 semi armor piercing {SAP}), intended to be launched from carrier-borne aircraft in conditions of good visibility, against maneuvering targets. Launched from 15000 feet (4500 m), it had a range of almost four miles (eight kilometers), and could be controlled at up to 24 miles (45 kilometers).

A launch speed of at least 200 mph (320 kph) was necessary, so its low wings would not stall; a 990 pound (450 kg) static thrust 8AS1000 jet assist takeoff (JATO) bottle in the tail boosted it to a maximum speed of 600 mph (960 kph).

Operated by radio command guidance, Gargoyle was tracked visually by means of flares in the tail, much as Fritz-X was; this limited its maximum range to how far the flares could be seen. Gargoyle relied on similtaneous or separate operation of the elevators and rudder on the weapon's butterfly tail; it was capable of 4g, for a turning circle of 2550 ft (777 m).

Production by McDonnell Aircraft began in 1944, but the war ended before it entered operational service.
