Indeed it would and it would also make sense for the PLAAF to replace those sold with new production ones using the WS-10, but would that fit to the point
@The Eagle noted, that Paksitan won‘t compromise quality when the should get used fighters?
People needs to understand that PAF is regarded as a top class fighting force highly disciplined and at par with any modern force out there despite of limited resources/options. In no way, any one should have a doubt on this. Even though, I didn't acknowledged neither claimed anything on AL-31F but one has to keep in mind that PAF is not going to compromise. That being said, whether AL-31F or WS-10; the top notch will be chosen by blue boys. IF J-10CP is here, it is going to be the spear head for PAF and in that area, there is no other option but to get the best out of it. I will hold down myself till the birds lands. We will then discuss as how, when it happened---- who was in China since when and in-fact how many of us (almost 6 members) knew from early 2019 or even before that.
I acknowledge & agree what
@SQ8 used to say that any information which is for personal delight, shouldn't come to the internet unless Source say so. Secondly, any responsible person having information on any such topic, wouldn't compromise the OPSEC for few brownie points. Lastly, we all need to act responsibly. Either the J-10 or as I used to say, not only J-10 but a lot coming; means it is a huge responsibility to keep things close to your chest until the time comes.
Getting back to the topic; AL-31F has its own advantages and PAF sees that close coordination with big wigs for the future of Pakistan Defence Industries. A lot has been settled and clarified between Pakistan-Russia and I wouldn't shy to accept that thanks to China for playing a bigger role in this regard. This is same as like how Pakistan played a bigger role to clear the path for Chinese reaching the Gulf Defence Industry.
Currently, whatever being said on internet and as revealed by officials through different channels; is merely the tip of iceberg. Having said that, if even 40% of the desired modernization is revealed; I bet people will remain in shock for at-least couple of weeks if not a month.
Have you ever seen me opposing particular platform or even trying to say that so & so person is making such a stupid claim that if J-15 or J-16 or any Flanker is coming? I bet you wouldn't find me seriously doing so. You know why? I do not look at merely a platform or an opinion of someone wishing PAF to have a flanker. What interests me, is the case of seeing far beyond just a platform or an equipment. I am more interested into things impacting Country's Defence in long future.
I believe that any professional force like PAF just do not buy an equipment to live through the day and survive for tomorrow. You might not believe but PAF plans for 30+ years to the least if anything is procured or inducted into the active operations. By that logic & tactics; one can easily understand that which tech might get interest of PAF and how come the same can benefit Defence of the Country by any means or different ways. While pointing to something being interested to PAF; just pay close attention to the benefits and future lies ahead in-form of that particular platform/equipment, people will get the idea as how PAF or PN or PA is planning. How beneficial it is and how this is going to support in very long run.
If we are talking about AL-31F engine with J-10C for PAF; I wouldn't deny that plainly rather be looking at AZM becoming reality, an NGF becomes the reality and taking shape, a defence industry of Pakistan moving forward and all these factors will be combined with the help of Friends indeed. PAF may not be bringing the AL-31F or WS-10 merely for the sake of it. Trust me. It has more to do with future tech, development and progress being made to meet with modern warfare challenges. I have no doubt that Russia, China & Turkiye are already helping in different areas and the future path has been set.
Unfortunately, public denial is because of an ill painted picture of Pakistan. Don't take me wrong (everyone) but not everyone has to stomach to digest what PAF, PN or PA has been up-to. Unfortunately, most of us never tried to look at the right side of the picture but this is us keep asking for everything on platter and being spoon fed. I am not denying the fact of OpSec and secrecy level being maintained by Pakistan or China as everyone does so but did everyone belittle the particular nation or undermine them as if their defence capability is nothing at par in modern times. Surprisingly, no one ever could get the idea as how Pakistan has been the center of power struggle in the region and plays a major role to set rules. No one ever could look at things that Pakistan did. It is a dilemma but a reality since majority believes in the narrative being pushed by leading or major media outlets. There is a less of interest by the people to dig deeper and look at the things as they are instead of how they tell us to believe.
The reason as of the same proven fact that PAF do not race into quantity with the rival but always comes ahead of quality and delivering the result. This is all about to control the end game.
... but even if I agree, that CAC had a design "up its sleeve", such a design to complete will take vast amount of resources and if it is - like you say - "no project Azm" - then I see no chance for yet another fifth generation type! Anyway ... most interesting.
I did not put him on my ignore list, so i can read his absurd posts
