Su-57 Felon

SU75 is the heir to the SCAM-FA PROGRAM.

India isnt going to jump in those waters again. They are better off jumping on board the KAI KF-21. The Su-57 is dead in the water and isnt going anywhere. At this point it is nothing more than a vanity project and airshow demonstrator.
I think the only recognition it will get outside of Russia (other than video games) will be part of the boss fight in a movir for a fictional wreckless USN fighter pilot who should have been grounded for all the safety violations in his career or was constantly passed over for promotion.

Who cares what the SU-57 can do or not do. After what we have seen over the skies of Ukraine the Russian fighter mystique is nothing but smoke and mirrors.

Despite Ukraine/sanctions etc, I still think they make a go of it.

National vanity project, Vlad won't let it die. Unless maybe he does, but I still think it'll somehow survive. Look how long they took to get the Flanker right. OK, it's not performing well in Ukraine - but a lot of that is poor planning/leadership. The SU-35 (despite being shot down via ground fire) is still a respectable machine. According to Ukranian Mig-29 pilot "Juice", it still commands their respect.

So even if they just field 50, it'll still be a program of record. Likely the least produced/feared of all wanna be 5th gens, but they've got over a decade now sunk into it. The SU-75 will never materialize, not after Ukraine. The SU-57 is the only solution... much like the F-35 is for Western airpower.

That, and the new engine for it will continue to be developed IMO...

What barriers prevent Russia from fielding Su-57 or -75? Certainly not energy, materials, knowledge, or persistence. Never underestimate them.

The Su-75 was nothing more than a concept looking for a partner to co-develop it. Yet, that possibility is pretty much gone now.....

The "problem" or "barrier" is that the Russian tank turrets fly better than the Su-75

One of the biggest and most expensive problems/barriers to the development of Su-57.
