The Russians never gained air superiority due to the fact Ukraine were still conducting air ops after the invasion whereas the Russians were very limited in theirs.....with the introduction of western ground to air weapons, any Russian air ops were ground to a halt...I think they have air superiority. Ukraine can fly but are losing a larger portion of their air assets than Russia is. I do think the Russians were not prepared for the tenacity of the Ukrainian ability to strike them in the air, so they are just softening them up with cheapest method. Just bomb into dust everything they can reach with the cheap stuff.
Of course I'm not there but I do know a few people who are and they were saying Russian helos are pretty much all grounded and flying only if they absolutely have to...
