I wouldn’t drive hype either but those F-16s are some serious capability. Not really so much because they would be that much better airframes as what Ukrainians are already flying but because they can carry a metric fuckton of different NATO armaments that are currently sitting in warehouses that can’t be shipped to Ukraine because Ukraine wouldn’t be able to throw them at Russia, or only with questionable effectiveness – say, those air-to-air IRIS-T that Germany is sending over: They integrate into IRIS-T air defence but launched from the ground they’re very short-range^1^. Having F16 means that Ukrainians can also strap them to planes, with system integration close to that of an Eurofighter.
^1^ they don’t care about launch orientation at all, that’s their point you can launch them in the opposite direction upside down while spinning heavily and they’ll still find their target. But the air-to-air variants just carry less fuel
