Thanks sir for your valuable reply and true expert opinion
@Mastankhan
IMO i just shared idea that PAF give hint of heavy leasar weapon, so they might minus few expensive 5th gen feature and add one and two feature from next gen list, creating there own combo considering cost and requirements.
otherwise local production of J31 or mini J20 can serve purpose but PAF want there own set of features, so they have allocated enough time for it. (Of course will taking basic technology stack from china and will add there own with help of _ _)
5th generation jet have some mojor issues along with to much high flyaway cast vs effectiveness, which are alien for others.
American stop production of F22 along ago , instead going totally F35 they are moving back to F15s.
Russian struggling badly with SU 57 that way given 6th generation program to Mig series as mig 41.
About Chinese jet, No body actually know what are capibility of J20 or how J31/j35 will perform in future.
Other countries specially European skipped 5th generation and moved towards 6th generation or can say 5th generation +
Coming back to PAF, as we know one of main feature of 6th gen will be leaser waapon, we will not be near to 6th generation at all, even counteries working on it not sure what thay can actually achieve its much asking for them considering feature set like
manned and unmanned switched
Over expectations from artificial intelligence .
Losely coupled Component approach to change quickly for any role with same aircarft.
Many other of wish list
