I’ve come across a declassified CIA document from 1972 illustrating a speculative Soviet air campaign in a Cold War turned conventionally hot. Having just emerged from the nuclear monomania of the past decade, it shows the weaknesses of the Soviet air forces in what was new territory for them. Almost everything was either too short-ranged, too vulnerable, carried too small a bomb load for conventional war, or a combination of the above.

That being said, it still would be very formidable to oppose, especially by the standards of “we only need to hold the air above the North German Plain for a few days”.
