The Space Shuttle's cargo bay was the size it was so it could carry military satellites to orbit. Vandenberg Air Force Base was going to be a west coast launch site for the shuttle, and it seems as though every astronaut use to be a Navy pilot. Our program was plenty "militarized."

At least 11 space shuttle missions had classified payloads, it's reasonable to believe most of these were spy satellites.
