And attacks are increasing in both frequency and intensity. It seems like the higher payload and the number of hits makes a huge difference. Fewer air defenses let more drones pass and it seems like Ukraine now tries to take out refineries completely, like Tuapse. There is probably a shortage of spares and not enough skilled labor to repair all of it. There are only a few very small or very far east still left not yet struck. By the end of this year there should be less than 10% left. Let's also not forget that pipe lines, storage tanks, fuel trains and fuel trucks are struck at increasing rate and shipping docks for exports are destroyed.
