The “vampire drones” aren’t drones but 122mm rockets fired from an Czech RM-70 MLRS, an unguided saturation bombardment weapon aimed at civilians for the umpteenth time by Ukraine. Since these are relatively short range weapons they’ve started bombarding Belgorod more since Donetsk city isn’t within safe firing ranges anymore after the fall of Avdiivka.
Bombing runways is almost completely useless unless done on a daily basis, since the repairs can be done quickly and cheaper than the cost of whatever ballistic missile they use. Blowing up the airplanes in the hangars incurs an irrecoverable loss to the tune of a hundred million dollars give or take.
But even were Iran or anyone else to hit some expensive F-35 or similar NATO bullshit plane they will never confirm the loss officially or do so reluctantly weeks later; case in point, the whole F-16 debacle currently in Ukraine.
