So, the Aerospace Forces (VKS) of Russia has about 1,500 combat aircraft. Ukraine has 200. At the same time, most of the aircraft were produced during the Soviet era, and the modernization was ambiguous.
Experts write that the Ukrainian military aviation can hardly be compared with even one Russian military district, let alone the VKS as a whole.
In addition, when attacking Ukraine, Russia can use tactical missile systems and artillery that will attack airfields with combat aircraft. Therefore, the Ukrainians should redeploy their own fighters to the western part of the country and contain Russia from the eastern direction with air defense systems.
