Su-57 won't get into Pakistan, if Pakistan continues its SAM procurement (and it really needs to per Sindoor experience - so it most probably will do just that). It will fly outside. Closer and much safer than any 4th gen, sure - but still outside.
Everything else is sort of secondary - even winning back local tech superiority over border region a-la Kargil war doesn't mean that much; Indian ambition (which they in fact demonstrated in 2019, and failed to demonstrate in 2025) is ability to enter Pak airspace. Stand off, they already can, and can very well; India didn't even unleash their true non-nuclear firepower in may (Darwin award: win non-nuclear competition and get a nuclear one). Their visible goal is not to settle for that, but get more. Only stand in ops promise more than what they already can. And only stand in ops promise even slight hope to do something with PAK nuclear option.
Yes, Su-57 will probably screw over Pakistan even more over sea - but it is already hopeless there, PAF composition just doesn't support long missions over sea very well, no matter weapon/sensor superiority; IAF and IN air arm just do.
Yes, su-57 is very likely to push PAF away from border region just through their specs, making Rafale AASMs matter again. But it is another tit-for-tat, if PAF procures FC-31 in the future, su-57 doesn't appear to be ideal frontliner against VLO.
Espeeecially if you replace its DBR set with our precious Uttam. J-35 most probably already has GaN x-band set. It already likely supercruises. And, of course, X band stealth.
Sindoor is interesting. On one hand, it was a spectacular failure to execute "strike package" theory - which was simply intercepted head on and disintegrated under fire. It wasn't even under truly challenging circumstances - Indians were stopped without IADS playing role.
But that was first
On the other - later fires exchange evolved into same aerial stalemate we see over Ukraine; which is perhaps normality for most air forces (only US and Israel are proven to be able to break in, and among other perhaps only China can be really expected to be able to do it).
In this stalemate, India did very well in stand off "mounted archery competition", having more, better long range fires than Pakistan. But...do you really need su-57 for that?
Indian pride, bread and butter is Brahmos series. Big Brahmos versions already fly on Su-30MKI and they won't fit into Su-57.
Smaller Brahmos-MA will probably fit under wings no prob (and Russia won't have any problems integrating the, which i very much doubt for french) - but so can hundreds of other indian 4th gen aircraft.
Same is true for Rampage, LORA, and so on.
Su-57 stand off munitions are excellent - but they're unique package, on top of already procured Rafale one.
My posts aren't against su-57 - i am quite fond of this aircraft (though always find ironic that it didn't end up something even Russia needed the most). It just shows that Indian situation isn't black and white.
