EMP blast, nets, lasers, signal jamming - there are a few ideas but nothing full proof.

I've heard of multiple people just shooting then down if they trespass, so there's always guns.

I can't remember the article but I saw on HN a story where law enforcement triangulated a drone operator who was doing something criminal like smuggling. I'm sure that would be just as beneficial for deterrence if the operator knew they would be found.

Serious question: Has there ever been an actual weaponized EMP on any scale? I’ve never heard of one, and there seems to be real doubt among nuclear arms control experts that this is likely or even possible in a practical sense.

Not that I know of, just ideas at this point.

I've seen a few companies not just signal jamming, but actually hijacking the radio signal to take full control of the drone.

Still plenty of consumer models have full autonomous modes guided by gps, so I guess that's got to be part of the mix too.

I think just the act of detonating a nuke sets off an EMP. However all electronics getting fried just before the entire city is incinerated ranks pretty low on the priority list.

Well that's kind of the thing right? Once you launch your ICBM, the fate of your cities are already sealed. On top of that, the effects seem to be highly variable. From a practical point of view, you might as well just use them in a traditional manner.

There is a cruise missile capable of delivering an EMP-like effect under development.

I wonder if directed energy I.e. microwaves could work?
