The problems you mentioned are all about the engines,and the engines come from Russia it's nothing about China.Paf choices the RD93MA,then you have to wait for it.
It depends on what kind of threat you will face.CAMM-ER or ESSM is good enough for now,but they will be eliminated by hypersonic anti-ship missiles like Russian's 3M22(Zircon) in the furture(within 10 years).In fact CHINA needs a new generation high speed(>6MA ) medium range(>100KM) anti-air...
Su-72 looks a good fighter,but serial production start in 2025~2026 while maiden flight start in 2023 is impossible.No one can finish all the test of one 5Gth fighter in 3 years....if russians have such capacity then they will at lest have dozens su-57 in service now.
I know your means pro,but i didn't say HHQ-16C is working now at the existing ships too....PLN didn't want to change much to the old 054A to acquire more air defense range at the last five-years plan until the latest five-year plan is begining at 2021.So does the hhq-16c will in service with new...
If Turkey buy some(≥36) su-57 with type30 engine,then i think the Russian will allow Turks to buy some type30 engines additionally.Anyway, Turkey needs advanced fighters against Greece and its allies now while Russian indeed lack of money.
1.F-22P do have 2X730 simplified version above the helicopter hanger.
2.PLN will purchase 8X055,12X052DL,20x054A block2 and some new 057 during the 14th Five Year Plan Period(2021~2025).
They are mistanding,it's true that each AJK-16 FC-RADAR can suport you shooting 1 or 2(under certain conditions) targets with launching 2 missiles,but 054A has 4 AJK-16 FC-RADAR totally....
Purchasing Type30 engines from Russia is a possible and good option for project TF-X.And other techs Turkey can ask for help from EU such as manufacturing Integral titanium alloy fuselage frames etc.In a word, as long as you have enough money, the problem is no longer a problem.
