KH-9 (BYEMAN codename HEXAGON), commonly known as Big Bird or Keyhole-9, was a series of photographic reconnaissance satellites launched by the United States between 1971 and 1986. Of twenty launch attempts by the National Reconnaissance Office, all but one were successful. Photographic film aboard the KH-9 was sent back to Earth in recoverable film return capsules for processing and interpretation. The best ground resolution achieved by the main cameras was better than 0.6 metres (2 ft 0 in). They are also officially known as the Broad Coverage Photo Reconnaissance satellites (Code 467), built by Lockheed Corporation for the National Reconnaissance Office. The KH-9 was declassified in September 2011 and an example was put on public display for a single day on September 17, 2011 in the parking lot of the Steven F. Udvar-Hazy Center of the National Air and Space Museum. On January 26, 2012 the National Museum of the United States Air Force put a KH-9 on public display along with its predecessors the KH-7 and KH-8. Thanks for watching !!
