The S-300’s and S-400’s are in Russia proper, they don’t move them forward. Instead they’ve been depending on other short range mobile anti-air platforms, which the Ukrainians have been good at either capturing or disabling.
Excellent info & thanks!
My question was a bit of a setup. I have read many Freeper responses that the S-300’s and S-400’s are providing air dominance for Russia. Clearly not the case.
Although some of the S-400 missiles could reach the Ukrainian aircraft, the S-400 radar does not have over-the-horizon capability.
