Likewise in the aerial space, the development of air defense technology over the past couple decades, as seen with the S-400 system, has outpaced the ability of airplanes to evade air defenses.

Ground based air defenses are vulnerable and can be suppressed by electronic warfare and anti-radiation missiles.

The Russians seem to be relying on missiles rather than aircraft to carry out both strategic and tactical interdiction, while CAS as a concept seems to be largely abandoned because it is simply too risky in a modern battlefield.

The Russians are relying on missiles rather than aircraft because they know NATO is covertly supplying the Judeo-Ukrainian regime with targeting data. NATO fixed radar, AWACS, and aerostat radar track every Russian warplane movement and provide Ukrainian air defenses with a firing solution.

Russia can't suppress Ukrainian air defenses with anti-radiation missiles because they only have to turn on their fire control radar momentarily when they fire a missile.
