Spying and the Hexagon KH-9 Reconnaissance Satellite
Introduction
The purpose of this blog is to provide information about the last film based spy satellite program that launched 19 vehicles in a polar orbit around the earth between 1971 and 1986. It was a key asset that helped keep the peace during the cold war. It was considered the most complicated satellite ever put in orbit and allowed President Nixon to sign the first SALT Treaty and permitted President Reagan to say "Trust but Verify." It did the photographing of military assets of denied territories. The program was declassified in 2011.
In addition to discussing the development of Hexagon, its importance, some imagery photographs Hexagon took of some Soviet assets, the blog will discuss some recently declassified information about it. Other topics will eventually discuss security, technical data, photographs of and personal memories by some participants at the company that created and built the camera system, the Perkin-Elmer Corporation in Danbury, Connecticut.
