The Gorgon was an air-to-air missile powered by a turbojet engine and equipped with radio controls and a homing device. It was developed by the U.S. during World War II, was later expanded into a more general program including turbojet, ramjet, pulsejet, and rocket power. Straight wing, swept wing, and canard (tail first) air frames were investigated and visual, television, heat-homing, and three types of radar guidance were looked at for use as possible air-to-air, air-to-surface and surface-to-surface guided missiles and as target drones.
