Hello:

This has been a great thread ! I was born in '56, but still had to learn
tube stuff in electronics class in H.S. I am reminded on the pilot that
defected from the USSR and flew his MiG to Japan. Everybody was amazed that
the radios on-board were all in tubes.

        [Steve Katz]  I'll bet the missle wasn't "all transistors" in 1963.
The guidance and targeting systems used high voltage microwave tubes
throughout the 1970s, including SAMs and AAMs.  Of course, a lot of those
late 1950s designs didn't actually reach production levels until the
seventies (no kidding).  We were building (Army) Hawks designed in '63 at
Raytheon/Martin (forebody/aftbody) in 1978; the Patriot didn't go into full
production until after that, and its acquisition system still used
tubes...ditto the Sidewinder, Sparrow, etc.  -WB2WIK/6
