Planes have a large sky to move around and the targets are generally fixed or slow moving. Hence planes generally had the advantage in hitting the targets. But with the supercomputing arriving, the situation has changed. Now the SAMs are getting upper hand over planes except in hilly terrains.
Jamming can be both ways. The ground radars also can jam the radar vision of the plane.
F22 is not yet tested against strong foes. That does not make F22 invincible
Destroyers are ships and hence they have limitations in thing like power generation, control over distant parts of seas etc. But ground based systems have unlimited power from power plants and can have lots of ground infrastructure for area denial. Moreover, till the advent of super computing, planes had upper hand over SAMs. But now things have changed after super computing arrival.
That makes little sense. Supercomputing arrives for air power too, making geolocation and identification of threats easier and quicker, and it also makes EW more effective against them.
It makes no difference because planes geolocate threats from their emissions. A jamming threat can be geolocated just as easily, and using the same methods as a radar threat, and this is all done passively. ARMs can also home passively.
Neither is the S-300/400/500. In fact it's not been tested against any foes.
SAM batteries are not hooked up to the electricity grid and neither are their radars or support jamming. A large ship can generate way more power than a ground vehicle, and hold way more computing power, yet aircraft carriers are still regarded as way more important than air defence destroyers.
