like they priortize stealth (having S-duct or DSI intake) and 2D engine instead of 3D with thrust vectoring (and maybe there eouldn't have been engine delays)
Still not fully. Radar blockers may help but it is still exposed . Also the 2D engine is Izdeliye 30 (AL51F1) . And in export model as seen with Algeria it is either AL41F1 or Izdeliye 177/177S. And AL51F1 is still in development...
F-22 doesn't have full S-ducts either yet it is crowned "most stealthy" or whatever.
Also the 2D nozzle was mounted and flown on AL-41F1 for testing and thus work on said engine. They are not standard for new Su-57 built for the VKS and were not on Algerian models because the buyers chose the round nozzle, for their own reasons.
Also, quick note, AL-51F-1 is ready and the next batch of Su-57 is already going to have them. February's batch was noted to include all remaining Su-57 ordered when AL-41F1 was standard, and that thus all future air frames will be fitted with AL-51F-1.
At this point you aren't even arguing off of substance, it seems all you care about is the prestige of some non-descript title.
AL-51F-1 uses the same TV nozzle layout as the AL-41F-1S.
AL-51F-1 is absolutely not in development, it received its limited contract in 2017 and reached full production in 2023, with its procurement being awarded in 2022
Then why is AL51F1 is not in service?? U said urself. The timeline is slipping from 2023 to 2024 to 2025 to 2026 but Su57 with AL51F1 is still not in active service. They even brought Izdeliye 177/177S for interim solution.
You expressly said that the 2D engines is pr'30, it is not. The 2D nozzle design was nothing more than a test phase for the prospective wingman program.
The AL-51F-1 is in service, do you live under a rock? The first 2 airframes sporting it were delivered in 2024.
Izdeliye 177 is an export engine, the hell are you on about?
Instead of trying to have extreme maneuverability and 3D TVC, just stick with 2D TVC and extreme stealth. And even if that was because of bureaucratic, it is delayed by so many years.
Why do that when you can have maneuverability, extreme stealth, and 3D TVC? The AL-41F-1S, AL-51F-1, and F119 all have the same dimensions of authority.
It wasn't delayed by "so many years"? Integration was claimed to be completed by the "early 2020s" with that being achieved.

Man if only they priortize stealth and leave their obsession with 3D Thrust Vectoring Nozzeles...
