The russian air farce has been pretty much non existent throughout their failed war on the Ukraine. The Ukraine air force is practically non existent, and has no bombers capable of carrying out "strafing" runs. They have old russian fighters that they continue to repair.
The Ukraine pilots are not stupid enough to go up against the modern russian fighters that are much better when they do show up.
No air war, because there is little air power in Ukraine that needs to be resisted.
