Gambit 3 KH-8
DAYTON, Ohio -- Gambit 3 KH-8 is one of three formerly classified reconnaissance satellites now on display at the National Museum of the U.S. Air Force. The three satellites were among the most important U.S. photo reconnaissance systems used from the 1960s to the 1980s, and played a critical role in winning the Cold War and maintaining U.S. national security.

The GAMBIT 3 KH-8 photo reconnaissance satellite improved upon the GAMBIT 1 KH-7 by providing much better image resolution. Its great spot-surveillance capability complemented both CORONA and later HEXAGON wide-search satellites in tracking adversaries' weapons development. GAMBIT 3 was a long-lived system, and completed 54 missions from 1966 to 1984.

The most notable advancement from GAMBIT 1 to GAMBIT 3 was the addition of a "roll joint" between the camera module (the forward part on display) and the Agena control vehicle in the rear. This rolling joint made the satellite extremely stable as a photo platform, conserved film, and increased the number of targets photographed. In addition, new super-thin photographic film allowed the vehicle to carry more film.

General Electric built both the vehicle housing GAMBIT 3 cameras and the recovery capsules, while Eastman Kodak made the cameras. Lockheed built the Agena spacecraft. The Air Force launched GAMBIT 3 KH-8 satellites aboard Titan IIIB rockets from Vandenberg AFB, Calif., and provided tracking and control at an Air Force facility at Sunnyvale, Calif.. USAF aircraft recovered the film capsules in midair near Hawaii.
