Frankly, I am not sure what the major utility of the Ada class would be for PN. It is another ship with only point defense systems and not truly multirole, which is the need of the hour for PN. I agree with
@Penguin that most engagement with IN would be via SSKs (of which PN will have 11). However these often would be sitting ducks against IN's sub-hunters in without surface protection in the form of Frigates/Corvettes. Now F-22P is moderately larger than the Ada. It is significantly longer (by 23m) though is slightly narrower with a beam of 13.8m vs 14.4m and has a slightly shallower draught (by 6in). Concominantly it has a max load displacement of 3100t vs 2400t of Ada. If redesigned along the lines of the C28A but with VLS systems like Sylver A50 with Quadpacked Umkhonto-R or CAMM, it would carry far more firepower for protection against aerial targets, than the Ada. In the proper load-out, it could be capable of carrying 96 - 128 medium range SAMs and if the boxes for C802 were moved to around the hanger location, could also carry 48 FL-3000N Short range SAM.
The TF-100 is not even a thing anymore and will be filled out by MILGEM Batch 2 AKA MILGEM-G which a
@Penguin pointed out, will be 10M longer and carry ESSM and (like ADA-Class), the RAM.

That places tremendous risk for PN given that ESSM May not be cleared for sale by US. If it is, that great, get a mk41 and place it on the Alamghir as well, but IF PN really wants to proceed with Turkish involvement in its corvette/frigate program, i would request that they RAM be replaced with FL-3000N and that Mk41 with ESSM be replaced by Sylver A50 with Umkhonto-R or CAMM.
Regarding the T-129, i actually prefer this given that it will be up to NATO standards vs the Wz-10. The Mi-28 will be a long shot. With the T-129, you could go for the Rolls-Royce Gem 2-1004D which powered the Mangusta (A-129) which would make it slightly less sanction prone as it is coming from UK. It would enable local weaponry to be integrated, like the Barq Missile instead of Hellfire/Umtas. Barq (likely being based off AR-1) has a suspected range between 8-10km. Having the Mi-28 would likely prohibit that use. More than its capabilities, it diversifies PN's suppliers and gives potiential for local manufacturing which Mi-28 for sure wouldnt.
