Of course, given your intelligence, you think the Su-30MKI can easily defeat the J16/20/35 and our 6th generation fighters, it is not surprising that you think Brahmos is some kind of mysterious weapon that is difficult to intercept
Fighters do not operate in isolation. Whether you win or lose depends on whether your sensors can pick up threats, and they do not have to be present on fighters. The shooter can be anything; SAM, 4th gen fighter, or 5th gen fighter.
For example, if my fighter radar cannot pick up a J-20, but my ground radar can, then I will get my firing solution...
Within our IADS and upcoming C4ISR, any one of our jets with the right weapon can engage and kill next gen jets.
That's why the IAF isn't worried about the semantics around 5th gen, 6th gen etc.
We have two goals, protect our airspace and kill them in theirs. Fighters and drones will protect our airspace. And Ghatak and drones will kill them in theirs. That's our plan. So the fighters can be 4th or 5th gen, it doesn't matter. What matters is what sort of information we can collect and send to them, and all they have to do is get into position and fire their weapons. So the information network and the weapons have to be on the level required to kill the J-XX.
AMCA will be able to handle more information more seamlessly compared to older jets. Its level of stealth will be outdated when introduced, but it will still be enough for our needs.
We currently do not need platform superiority. That can come 10 years after AMCA.
