Fairchild SD-5 Osprey

In 1958, Fairchild received a U.S. Army contract to develop a jet-powered surveillance drone for the AN/USD-5 drone surveillance system. The drone itself, named Osprey, was referred to either as SD-5 or also as AN/USD-5, although the latter was more properly the designation of the whole system. The Osprey first flew in May 1960.

SD-5


The SD-5 was a subsonic delta-wing aircraft powered by a single Pratt & Whitney J60 turbojet. It was zero-length launched with the help of a single solid-propellant rocket booster (giving 178 kN (40000 lb) of thrust for 3 sec) and recovered by parachute. The drone had an operational radius of 1600 km (1000 miles) and could fly at altitudes between a few hundred feet and 10700 m (35000 ft). Projected payloads were infrared scanners, side-looking radar and optical mapping systems. The sensor data could either be transmitted by radio or stored for examination after drone recovery.

The Army had planned to have the AN/USD-5 system operational by 1964. However, in November 1962 the program was cancelled because of budget constraints.
