This seems superficially reasonable, but it looks like the TB2 Bayraktar was used to bomb the fuel depot in Bryansk less than two weeks ago and that's 150km into Russia. They seemed to have used the TB2 the other day on Snake Island. As of a week ago there had been 6 internationally confirmed incidents where a Tb2 was shot down. They were known to have had at least 20 when the war started and have received more sense…
It's a very solvable problem though. At least for countries other than Russia, which might not be technically nimble enough to adapt mid-conflict and under a strong sanctions regime. S-300s/S-400s/Buks and the somewhat rarer western equivalents like the Patriot system just aren't designed to target something flying that slow with that small of a radar cross section. That doesn't mean the drones aren't reasonably easy…
Or just, ya know, shoot the damn thing.
The specs are well within what you can expect to hit with with an "old enough they give them out like candy" AA gun.
