chill dude. its all speculations. there are people who right now claim Pakfa is crap. just like pakfa, even f22 has never been in an aerial engagement. nobody knows how good its stealth is. It has never been exposed to anybody outside. And just for a second, think why has it been scraped in the first place. Is it really the price? If it was so, they could have slowed its production down. Instead of 2500 F35 they could have afforded 1200 F22. After all, the US is the biggest economy. I am not saying pakfa is better than f22. I know it isn't.
All I am saying is it is not impossible for Pakfa to shoot down an F22.
Even a Su30 can shoot F22 but with a ratio of 5:1 or something like that favoring the F22 of course.
It doesn't matter if the rcs is 0.001 or 0.01 or even 0.1, its still difficult to detect. And that is what is required. You can go down to 0.0000001 m2 but it won't help any good and that is what happened to F22. F35 stealth is not better than F22 but is good enough. We intend to do the same with Pakfa. I hope I can reach you.
American missiles are better. No doubt about it. But radar wise we gotta think otherwise. The Su30 radar is almost 5 times heavier than an F15 radar. Its PESA right now. Still very very effective.
Also more powerful the radar, more are the chances of detecting a plane even with a smaller rcs. About the reliability part. Yeah they are reliable. But maintenance is a different thing. They are more reliable but require more maintenance after every flight. Also it requires much more money. There are articles all over the web describing how maintenance heavy F22 is.
Just my 2 cents.
peace...
