On April 6, 1979, the Hexagon mapping camera, also known as KH-9, captured this image of Kubinka Airfield, near Moscow in the former Soviet Union. These three images show the airfield at 20X, 40X, and 150X magnification. The legacy Hexagon system provided the U.S. with impressive broad-area search and mapping capabilities from June 1971 to April 1986.

Interesting that those photographs were only Classified Secret. When I worked in a SpintComm relay center in about 1972, all traffic about those birds was in a compartmented program and usually TS code word.
