Ukraine's Air Force Targeting Policy

All of Ukraine's air bases are within reach of Russia's ballistic and cruise missiles. Even if you were to put Patriot to defend a main base that you were trying to set up F-16 ops on, the Russians still have Kinshel. The other issue is whether America would clear export of later model amorams because that's the air to a missile. Russian Air Force fighter combat air patrols are at medium to high altitude and often low-level, low supersonic.
