The program began in 1977, with a reported budget of USD $24,000,000; the design of the aircraft was closely based on that of Have Blue, except scaled down. Intended for launch from Lockheed DC-130 Hercules drone launcher aircraft, the original configuration of the Senior Prom vehicle included winglets and a ventral fin; the aircraft was later modified to include a V-tail and more slender wings, closer in configuration to the F-117 Nighthawk stealth fighter. Radar-absorbent material was applied to the airframe as part of its stealth configuration; in addition to the faceting of the design, similar to that of Have Blue and the F-117, the "sawtooth" wing profile bore similarities to the B-2 stealth bomber's planform.
