A carrier's radar has a vastly different power budget than basically anything else which is mobile, though. I mean, the AN/SPY-1 puts out a full megawatt of RF power. Even the gas turbine on an M1 Abrams tank, if it was coupled directly to a generator and powering nothing else, can't provide enough electricity to run that. Hell, even if you put two of them together, they'd struggle.

That's not a traditional "EMP" attack, it's a brute-force assault with massive, expensive, and power-hungry microwave transmitting equipment that is never going to be feasible to deploy against drones.

It will be effective for maybe 50-100 yards. I can afford more drones than you can afford Aegis platforms.

Fun story, according to some whistle-blowers, after we started testing nukes and UFOs started showing up around test sites and and bases, it was our radars that fucked up their nav systems and caused the Roswell and other few crashes that happened in the late 40s until they adjusted somehow and the crashes stopped.
