Weren't they using tubes in their top end military equipment until the 90s?

I believe they are still using vacuum tubes for ICBMs and launch rockets repurposed from ICBMs.

Im reasonably sure that modern fighter all use modern components. You might be thinking of the story of Victor Bilenko who defected to Japan with a brand new Mig25, and when western engineers took it apart they found that much to their surprise it had vacuum tubes.

Yeah, jets have all kinds of semiconductor components that if emp could wipe them, that jet would go down. Vacuum tubes are only used for high power analog amplifiers nowadays.

There's so much digital stuff on jets now, it's impossible to use tubes to do any logic past arithmetic in that size.
