I believe Jinnah class Frigate will be a hybrid of ADA and Type 54A , it wont be classified as a Corvette but also a little less displacement than Type 54's , weapon package may include Harbah or Babur-3 CM , with probably the same VLS system that works on Type 54 .
I believe by 2030 PN will look something like this :
6-8 Type 54's
4 F-22P's ( Upgraded )
3 ADA Class Corvette
3-4 Jinnah class Frigate
3 Augosta 90B's
4-6 Chinese Submarines
Hopefully we Add 4 more Azmat class FAC's
and more Damen OPV's
