I'd say that those are a couple times more important than a couple dozen F-16s or AH-1s or whatever. Have you heard of something called System of systems or Network Centric Warfare? Even if that wasn't the case, say that the advancements in networking and low observability haven't been made yet; Radars, SAM missiles, Vertical Launch Systems for ships, MPA, AW&CS and Transport aircraft are strategic assets that honestly even a key NATO ally like Turkey can't get its hands on and has to develop alone.
On top of that, you have an emerging technological superpower ally right next door making you an exception and willing to provide you pretty much anything you can finance with financial help from said party.
-On a somewhat unrelated note-
Turkey had sent the LoR for F-16Vs on 15th of September, 2021. Since then, it hasn't even reached the Congress yet and from there it is in the best case dubious whether the sale would pass through.
2 years! 2 years of waiting for some crappy F-16s that Turkey have been operating hundreds of for the last 40 years and has an equivalent modernisation program with indigenous avionics and radar. Meanwhile Turkey wastes the valuable remaining flight hours of its F-16s, stationing them in Romania and Poland, protecting European skies like an imbecile...
And when it comes to the local production of 109 S-70i helis under the name of T-70; it turns out Turkey has to pass a new request through the Congress again in order to keep producing T-70s after the 38th helicopter. Need I remind you that this is a 10 year old deal people!
I'm not even talking about all the subcomponents embargo bullsh.t that Turkish companies had to deal with...
