Several people emailed me asking for more info on the spy sats I mentioned in my message on observing Mir. I don't know too much about them myself, except that I saw what I think was one of them once several years ago and the reason I think it was a spy sat is because it was so incredibly bright and fast moving. No idea which it was, though, because I didn't have access to orbital elements for any recon birds then.
Now, everybody does. Just grab the file http://www.io.com/~mmccants/tles/classfd.zip.
Unzip it and feed the file into any tracking program that can handle 2-line elements.
The only spy sats I know by name are the Lacrosse series - scan for them and you'll find several listed. They are reputed to be very bright and to have a distinct red color when observed visually. Gold plating? Who knows.
By the way, Ted Molczan, the Canadian Space Society, and a band of hardy observers around the world hunt these spy sats down visually, calculate their orbits from their observations and generate these orbital elements themselves. Quite a group!!
