This came up my mind too. Have read that a high altitude EMP bomb would cause havoc on modern infrastructure.

Not sure about the details though. Hope someone knowledge can chime in.

“EMP” is mostly a Hollywood thing. Not that is entirely fabricated or anything, but it’s almost entirely popular science articles and action movies, very little real weapons systems, and the movies create a lot of misconceptions.

https://en.wikipedia.org/wiki/Electronic_warfare is the closest related thing.

What you would actually do is see if you could jam its comms, hit it with a laser (these exist as actual practical weapons these days), or engineer tiny high altitude anti aircraft missiles, either something that already exists or small mods to existing tech for the use case.
