The Airgeep was developed to fulfill a U.S. Army Transportation Research Command contract for a flying jeep in 1957.

Power was by two 180 hp (134.2 kW) Lycoming O-360-A2A piston engines, driving the rotors by a central gearbox.

[3][4] It was re-engined with a single 425 hp (317 kW) Turbomeca Artouste IIB turboshaft replacing the two piston engines, flying in this form in June 1959.

[6] While the Airgeep would normally operate close to the ground, it was capable of flying to several thousand feet, proving to be stable in flight.
