In case you haven't been following Ukraine, that's what it's doing. It has multiple cheap long range drones (FP-1, FP-2, etc) plus more expensive ones (FP-5), and it's making them in the millions a year, I think.
They just took out 40% of Russian oil export capacity.
no, the million or two is small battlefield drones, mostly quadcopters carrying an RPG warhead or similarly sized payload. The long range drones - and they carry only relatively small, like 20-50kg payloads - are well under 100 thousands. FP-5 was declared 1 per day half a year ago. By now i think we've seen may be 10-20 such missiles used - they use real turbo jet engine, there isn't much of them available, and they are expensive.

Yes, Ust-Luga and Primorsk. Very successful hits. Painful for Putin. Yet it isn't a knock-down. Russia is like a big drunk guy in a street fight - just delivering painful blows to him doesn't help, you have to deliver a knock-out blow, and unfortunately Ukraine still seems far from it.
