Senior Prom was a classified black program conducted by the United States Air Force in conjunction with the Lockheed Corporation's Skunk Works for the development and testing of a cruise missile utilising stealth technology. Based on the company's Have Blue demonstrator, the six Senior Prom vehicles proved successful in testing conducted at Area 51 in the late 1970s; despite this, the aircraft was not selected to enter production, and the program was terminated in the early 1980s.
