1. Pakistan does not have any capacity, capability or knowledge to develop 5 Gen fighter to be very frank. Project AZM is nothing but a piece of paper sorry to say (Not undermining ourself but logically speaking we are nowhere in R&D of developing state-of-the-art weapon systems with high-performance applications). Even Turkey having long expertise in F16 still their 5Gen project is only on paper.
2. Anything coming from China will be the last bet for PAF in accordance to 5 Gen (most probably J31).
3. At first glance, J31 completely failed to attract audience because of its engines performance and also lack of interest by the Chinese AF in the aircraft afterwards.
4. China never make anything for Pakistan. They had zero interest in developing JF17 thunder (rather a testing platform or R&D purpose). Later when Pakistan officially jumps into the FC program (long story short our stupid AF think tanks wasted 1 and half decade to realized that the Americans are ******— looking for something cheaper to maintain and need something for a longer-run with no fear of sanctions, FC program was the last option at that time. When Pakistanis have shown interest into the FC program, then Chinese gotta hint okay we will help you to develop this to serve your needs else Chinese had zero interest.
5. J31 is again only designed and developed for the Chinese Air Force. If Pakistan need this, we should again become a part but we can’t modify from 2 X to 1 engine. The aircraft completely designed according to the core requirement of Chinese Airforce not for us or any third party technically.
6. Seems like platform design somehow close to F35 JSF, but the aircraft with two engines clearly shows they have something in their mind which is “carrier based naval platform” where you need power-pack machine for take-off and landing.
7. Again because of lack of interest by the PLAA, platform suffers a-lot. They want it but they’re not hurry... if Pakistan need it, we have to become a part of this project officially then might be Chinese will push this project faster...
