The Ukrs also claim to have shot down the greater number of them. If those claims are true, it suggests either that the drones aren't very capable, or that the Russians aren't using them right.
I don't think that actually follows.
Drones do not have high survivability. That's kind of the point: if you don't have a pilot, and the platform is relatively cheap, it doesn't need high survivability. So drones have always been vulnerable to anti-aircraft fire. The deeper you penetrate into enemy territory, the more vulnerable you are likely to become. Drones like Global Hawk can fly very high altitude and so aren't vulnerable to stuff like manpads, but a suicide drone can't stay high altitude.
The real question regarding whether Russia is using them correctly isn't whether a lot of them are getting shot down. The real question is if they are doing enough damage to justify their costs, including the loss rate in the calculation.
So as an example, let's say a drone costs $100k. If that drone takes out a target worth $50k, that's a misuse of the drone unless your enemy is a lot poorer than you. If you take out a target worth $1 million, that's a good use of the drone. If you need to send 4 drones because the enemy shoots down 75% of them, but you're still taking out a $1 million target, then that's still a good use of those drones.
I have no idea how much damage these drones are actually doing, and I doubt Ukraine is going to make details public in a way that really helps Russia evaluate their effectiveness. So I can't say whether they're using them well or not. But the fact that a lot are getting shot down isn't proof in and of itself that they aren't being used effectively. It just raises the bar on what's required to qualify as using them effectively.
Whichever is the case -- you'll join me in hoping that both are true -- the situation is bound to change. Technology will improve and operational methods will become more efficient.
Absolutely. War is never truly static.
