Or maybe they could do something like the F-117. Make the air intake a lot larger, and at the same time add a grill stealth protection. It would also protect the engine from debris, no?

The biggest problem is that it has no stealth coating and the engines are exposed unlike the F-22

There is no fixing the Su-57.

it doesn't really need fixing for what it is (a somewhat stealthy modern flanker), rather it's just not built in enough numbers, and russia can't do it currently.

It would be better, but you'd need to unfuck its base materials science and production methods as well. It would basically become a new plane entirely.

S ducts can't make shoddy build standards and design choices into a real stealth fighter.
It's the same with the other copycats like the KAAN or the KF-21.
Lack of RAM is also a deal breaker.

Imagine the IR signature those exposed engines give off.

It's biggest problem is that it's designed and built by Russians.

>>64016209 (OP)
It would help with radar returns from fan faces but also make the body of the aircraft less stealthy so you are just trading one problem for another.

>>64016209 (OP)
To fix the Su-57, you would need to focus on the supply side of the Su-57. Russia's airframe production facilities are decidedly NOT of a peer quality.

This photo contains almost half of the entire Su-57 production line.

Literally true. Well spotted, Anon.

the one thing they did very well with the su-57 is that it can fit 4 x-69 stealth missiles internally.
