The Aerojet SD-2 Overseer was an unmanned aerial vehicle developed by Aerojet General and Rheem Manufacturing Co.[1] in the late 1950s for use by the United States Army. Built in limited numbers, it never saw operational service.

Design and development

Development of the SD-2 drone began in 1957 by the Rheem Manufacturing Company, and the project continued through the company's acquisition by Aerojet General in 1959.[2] Developed as part of the AN/USD-2 surveillance system, the SD-2 was designed for truck launch using two solid rocket boosters; following launch, a piston engine provided propulsion. At the end of its mission, the drone would be recovered via parachute.[2] Control was provided from a translateration system for navigation (similar to the much later differential GPS technology), which allowed the aircraft to steer on a pre-programmed course.[3]

The SD-2 was designed to use a modular sensor system, allowing equipment to be switched between missions according to requirements. Available payloads included cameras for either recovered or real-time photography, an AN/AAD-2 infrared sensor, AN/DPD-2 side looking airborne radar, or equipment for the dispensing of biological or chemical warfare agents from tanks mounted under the wings of the aircraft.[3]

Operational history

Thirty-five production SD-2s were produced. Poor results from the navigation system resulted in the system's cancellation in 1966, and the program was terminated without any Overseers having seen operational service.[3] In 1963, the SD-2 was given the designation MQM-58A under the revised designation system.[2]
