I’ve read that some speculate that Russia is accepting losses of their planes, for air superiority to help them take territory faster.
But at this rate, they won’t even have enough to last the year!
Maybe they are hoping Ukraine will run out of missiles? Anyways it’s clear that Russia is willing to accept staggering losses, including losing 564 personel per day on average for more than 2 years now! (According to Ukraine numbers.) And even accelerate that number to almost double lately!?
