Lockheed YF-12A Blackbird Mach 3 Interceptor Prototype

The Lockheed YF-12A was a three-aircraft Mach 3 interceptor prototype developed from the A-12 to defend against supersonic bombers. Its two-person crew, AIM-47 missiles, high-altitude speed records, and 1968 program cancellation define a distinct air-defense and research boundary; the surviving aircraft later supported USAF/NASA supersonic-cruise investigations.
