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. So it doesn't seem like they've disappeared at all. So one can only assume that either Russia's air defense isn't as good as everyone thought, they aren't using it effectively, or the drone is harder to shoot down as operated than people thought.
