According to recent declassified documents, President Reagan commended GE employees for their work on a secret spy satellite. In September of 2011, the world at large learned that some 250 GE engineers and manufacturing workers were honored by a U.S. president. That president was Ronald Reagan and his presidential commendation took place 27 years ago, in August of 1984. That satellite is now on display at the Smithsonian National Air & Space Museum’s Udvar-Hazy Center and is one of 20 such satellites that were launched between 1971 and 1986.

The reason for the delay was the workers’ top-secret mission, which was only just declassified: They were building key components of Cold War-era spy satellites, the Gambit and the Hexagon. “I’ve been waiting for this to happen,” says retired engineer Fran Smith.

Smith, an Air Force veteran, spent 33 years with GE, including 19 years working on the satellite program. He said that on occasion he “had to travel incognito. My wife would think that I went to one place, but I would be somewhere else.” Smith recalled that “it was difficult at first to not to be able to talk about our job, especially with close family, but people eventually got used to it and so did we.”

The spy satellite programs ran from 1963 to 1986. The Hexagon was one of the largest spy satellites ever built. It was the size of a tractor trailer, 10 feet in diameter and 55 feet in length.

GE designed and built recovery vehicles for the satellites, command systems, mission planning software and other systems critical for the mission. The recovery vehicle for example was designed to bring safely to Earth the satellite’s precious cargo: The exposed film. This was still during the dawn of digital communications and the era when images can be beamed from space wirelessly.

The engineers were working with the cutting edge technology of the time: Transistors, diodes, and capacitors. Smith recalls that his top-notch memory system could store 1000 words holding 40 bits of data. Today, a simple memory stick can hold gigabytes of data.

Still, they succeeded. In 1984, President Reagan commended all of the contractors who worked on the satellite programs. He stated that “a generation of this Nation’s youth has grown up unaware that, in large measure, their security was ensured by the dedicated work of your employees. National security interests prohibit me from rewarding you with the public recognition which you so richly deserve.” The president stated that “the technologies we now take for granted had to be invented, adapted and refined to meet the Nation’s highest intelligence information needs while exploring the unknown and hostile medium of space.”

Although the Gambit and the Hexagon programs have been declassified, the photographs the satellites took are still secret. The National Reconnaissance Office stated that the programs gathered “highly detailed imagery of sensitive targets, and became a major source of information for photo analysts during the Cold War.” The NRO also said that the satellites served as “primary means for verifying Soviet compliance” with nuclear arms control agreements.

Says Smith: “I feel that because of these systems we were able to win the cold war.”
