The declassification of GAMBIT and HEXAGON was publicly announced on September 17, 2011. Two GAMBIT systems were developed for surveillance of specific targets. GAMBIT 1 initially launched in 1963 and was equipped with the KH-7 camera systems. GAMBIT 3 followed in 1966 and was equipped with the KH-8 camera system. The HEXAGON system was launched in 1971 and was developed for wide-area searches of denied territory. Together these satellites became America's eyes in space.
Additional Information can be found under NRO's FOIA: Declassified Records.
