Belgian designer Phil Pressel unveils the secret of his spy satellite, after 46 Years of keeping mum about it, according to, on October 14.

Reportedly, the spy satellite, KH-9 HEXAGON, commonly called “The Big Bird,” and the “Sentinel of Liberty,”was responsible in revealing vital images like they were only two to three feet away from the viewer.

High resolution images of significant information were gathered as it revolved around the globe. It has prevented a destructive war reportedly, by revealing in advance Soviet Union’s missile bases and other crucial military data. The declassified KH-9 HEXAGON played a major in the US reconnaissance program.

According to

“The HEXAGON was a search system, designed to capture military construction projects, repositioning of troops and materiel, radar installations and activity at submarine bases and airfields. Each sweep of the camera photographed a wide swath of terrain covering 370 nautical miles — the distance from Cincinnati to Washington — on every orbital pass over the former Soviet Union and China.”

Reportedly, Phil Pressel had kept the secret even from his wife for 46 long years, but the spy satellite is now on display at the Smithsonian National Air & Space Museum’s Udvar-Hazy Center for all to see. Below is the video disclosing the secrets of the KH-9 HEXAGON spy satellite.
