This facility was used by none other than LJB to direct the Vietnam War. We build this system in Mountain View, California at Ford Aerospace, Space & Recovery Systems. We also built and flew the KH satellites that provided the images. The hop was from Vietnam to a ship off shore, then to Hawaii to McClellan AFB and then on to Washington, DC. This system (Compass Link) provided secure voice, data and imagery at about 5 MHz. Very fast for 1968-1975.
