One of the projects I worked on at the former Rockwell Intl (now part of Boeing) was the MX Missile project. Down the hall from us was the Minuteman labs. Going to the Minuteman Labs was like going to a museum. The Minuteman guidance system used peanut tubes in it's circuitry.

You might be right.  Everything I saw was solid state but there may have
been something in there that was tube.  It was the Minuteman system that we
were installing.

I was in missile class in the Air Force in 1963 and the lab and course


entirely in tubes even though the missile was entirely in transistors.
adaptation was very short (minutes, maybe and hour) and said that
transistors worked like tubes except at lower voltages and power levels.
That was all there was to transistors !!!  Not bad really for a class


hadn't been rewritten yet (and that may have been all the instructor


that time).

[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


production until after that, and its acquisition system still used
tubes...ditto the Sidewinder, Sparrow, etc.  -WB2WIK/6
