From the main invasion thread, where it was starting to be a hijack:
To be clear, I wasn’t saying that I thought that one shot, one kill was currently possible (though with fully computerized aiming, you might be able to get close to that). What I was saying was that, whether it’s possible or not, that’s the kind of economy you need to make an anti-drone defense practical. If shooting down a drone costs more than the drone itself does, then the side using the attack drones can just bankrupt you by throwing more and more drones at you. Or they throw so many that you can’t afford to shoot them all down, and some still get through. Or both.
This is especially true with the sort of drone warfare that Ukraine has been favoring. When you’re attacking fossil fuel facilities, all it takes is one incendiary getting through to the right spot to destroy the entire facility. One turret each on four flatbed trucks isn’t enough to stop every drone from getting through, and it only takes one. Net result, the refinery or whateveris still destroyed, except now Russia is also wasting money on the defense platforms, too.
