Most modern US military hardware is shielded to withstand a certain amount. I would assume the Russian/Chinese makers are about as far along as we are in this respect.

My guess is some of the electronics is shielded in the radar/ missile batteries/control centers.... but not enough. The weakest links will be knocked out by fried electronics.

Shielding is done by using vacuum tube electronics/ by lead shielding/ my shielding with other metals. Someone correct me if I am wrong....

Mostly. In solid state electronics, materials and some non-industry standard techniques can also provide some protection. But that's the cost problem. Our computers etc are so cheap because they can make runs of thousands at a time. Going for "special" chips magnifies the costs enormously and lags a bit.

You think Congress screamed over a $10,000 toilet seat, what do you think they would do if today, we paid $200,000 each for a bunch (say 300) of 386 or 486 chips?

Shielding can be done with wire mesh. look up Faraday Shield. Lots of mis information out there about this EMP stuff.

Radiation hardened chips are regularly used in space. Semiconductor manufacturers are very good at making radhard devices.
