Will many NATO air forces be mainly obsolete by 2030?

Given current exhorbitant cost of fighter aircraft, will most NATO airforces be completely obsolete by 2030 when the F-16s etc finally run out of steam?

Right now NATO’s Eastern flank is pretty much obsolete (e.g. Poland’s Su-22s and arguably Polish and Slovak MiG-29s, Bulgaria, Romania, Croatia).

The way economies are performing in the South of Europe coupled with ever increasing costs of things such as F-35s, it is unlikely a number of airforces will be able to afford to replace F-16s, F-4s, Mirages or even F/A-18s by 2030. This includes Greece, Spain and Portugal.

Even Italy might not be able to afford to replace all AMXs and Tornadoes.

Modernising was a lot more easier in the past thanks to US sponsored production and cheap loans, and availability of relatively cheap jets ala G-91, F-5 and F-16. In addition relatively modern second hand jets were freely available from the US (e.g. F-100, F-102, F-4).

Other than Gripen, current crop of Western aircraft are expensive to buy and expensive to maintain.

And given much reduced production runs, 2nd hand examples may not be available.

So will most NATO partner airforces be thoroughly obsolete by 2030?
