Much has, to 50,000 volts per meter.
So the bad guys just up-power the space nuke effect to 100,000 volts per meter.
The 50K protection remains effective against the low energy, intra-atmopheric EMPs, or vehicle mounted DEWs.
Good points. I understand radiation, in the gamma ray and X-ray spectrums, because of what I do for a living, but in the electromagnetic spectrum as a whole with what is characterized as EMP...not so much.
From what I understand, it is the transmission over long distances that takes place outside the atmosphere that makes those types of airbursts at that distance so dangerous, because the gamma rays travel such a long way before interacting with the atmosphere and energizing the atmosphere, as opposed to a airburst in the atmosphere or near the ground.
I just know that they test platforms when they are designing and building them, but don’t know to what levels they harden them to.
