Frankly, though I should know about them ... until just now I had no idea there were so many different types ( and owners)

This is the pertinent part, I guess . But its all interesting
The spy satellites. The U.S. National Reconnaissance Office (NRO) operates satellites for the U.S. intelligence community. American reconnaissance spacecraft, including the NRO's major equipment, are launched to Earth orbit by the U.S. Air Force and are known by a variety of code names. They are spysats and they include these general types:
optical satellites that use a large mirror to gather visible light for photography -- like a Hubble Space Telescope pointing down at Earth rather than looking out into deep space,
infrared and ultraviolet satellites that record invisible infrared and ultraviolet light from below,
radar imaging satellites that uses microwave signals to peer through cloud cover and scan Earth's surface,
combo radar, optical, infrared and ultraviolet satellites that see wide areas of Earth's surface with more detail than the separate types,
signals intercept and detection satellites that tune in on radio, telephone and data transmissions,
ocean observation satellites used to locate and determine the intent of ships at sea.
One of NRO's mottos is "We Own the Night," indicating the agency's ability to collect data anytime of day in any weather anywhere."
So, JDB are we on the right track?
I saw The Hunt for Red October recently too. One of my favorite characters is Admiral Greer. That Darth Vader voice sells the whole deal. grady
