(From Wikipedia): Starting in December 1952, Fairchild began concept studies for a ground-launched long range decoy missile that could simulate radar signatures of large bombers.

(From National Museum of the Air Force): If several ground-launched, intercontinental-range SM-73 decoys saturated and confused enemy defenses, the real bombers had a better chance of getting through to their targets.

The Bull Goose carried electronic simulation and jamming equipment, and reflectors in its airframe made it look like a much larger aircraft on air defense radars.

(From Wikipedia): In December 1955, Fairchild was awarded a contract to develop Weapon System 123A which included the SM-73 missile.

The XSM-73 was powered by the Fairchild J83 on all test flights but was also capable of using the General Electric J85. The Fairchild J83 was operating by early 1957.

The SM-73 utilized a non-metallic fiberglass fuselage. A Thiokol solid-propellant rocket booster was used to launch the SM-73 to a speed of 300 knots (345 mph).

Cruise speed for the SM-73 was 488 knots (562 mph). The SM-73 had a fuel capacity of 803 gal (3,040 L) of JP-4. This fuel was stored in 10 fuselage and six wing tanks.

In December 1958 the program was canceled because the missile was not able to simulate a B-52 on radar. The Fairchild J83 engine program was also canceled in November 1958. Total program cost at cancellation was $136.5 million USD.
