Project CANYON SIGINT Satellite Black Program
Project CANYON matters because it moved American signals intelligence from short-pass listening satellites toward a more persistent high-orbit architecture. It was not a UFO retrieval system, an alien-monitoring platform, or a fictional black-project label. It was a real Cold War reconnaissance program: a series of highly classified near-geosynchronous satellites, commonly associated in open literature with AFP-827 / Program 7500, launched between 1968 and 1977 to collect signals intelligence from a high vantage point. The strongest public record supports CANYON as an early American high-orbit SIGINT and COMINT system connected to NRO, USAF, and NSA mission needs. What remains hidden is the full sensor design, exact target deck, operating procedures, ground-processing chain, and the intelligence reports produced from the intercepted signals.
