It's too funny because the F16 doesn't stand a chance against Russian air defenses. The US and NATO are giving Ukraine F16 fighters undoubtedly stripped down to the feature set reserved for buyers like Pakistan. They will lack any modern advanced electronics equipment to keep them from getting easily shot down. It's an old fighter at this point and without the latest upgrade packages is going to be cannon fodder for Russian mobile anti air, which is actually quite advanced.
Have they figured out how they will actually deliver these? I remember last year the "united front" of nato playing hot potato over who would deliver the jets.
Well, the Ukrainian pilots would need to stop flying into each other mid-air first to actually test the viability of an outdated airframe in contested airspace.
