So from now until 2025, SU-57 production line produces like 10 planes. Meanwhile 2025, F-35 will be numbered in the thousands.
Generally, I don't buy Russian face saving maneuvers like claiming a plane is TOO good, and it's been confirmed by two days non combat testing in Syria as a reason we shouldn't produce the plane.
It's BS, the Russians don't have the money, the industry, nor is the plane that good.
The Russians are not competing with the US, at least not at this time. And if the PAK FA is good enough to defeat the F-22, then those thousands of F-35s will not be very useful against the PAK FA.
As for this combat testing in Syria, the decision to not mass produce the Su-57 Stage 1 was taken years before this combat testing took place. It's when RuAF decided they won't be going for the 55 Su-57s by 2020 they promised earlier. Overall, they will buy some Su-57, but it won't be at mass production rates.
What the Russians have said is they will develop a sixth generation version of the PAK FA and mass produce that.

Russia may upgrade advanced Su-57 aircraft to 6th-generation fighter jet
This one refers to upgrading the PAK FA with 6th gen avionics.

The article also says the Stage 2 engine won't be ready for the PAK FA until 2024. The RuAF originally were planning to buy a lot of Stage 1 PAKFAs with the 117, which I've always thought is a very bad idea. There's nothing strange going on, the Russians have decided to jump a generation.
FGFA discussions on going is the equivalent of a face saving maneuver.
We don't need to do such a thing in the first place. FGFA is merely not a priority right now, but we still need an aircraft of this class. It will become important right after the new tender is done.
In fact, I have always supported delaying the FGFA in order to build up more advanced features than what's going into the Rafale F4. The Rafale will come with an advanced GaN radar with 360 degree capability. So I have pointed out that the FGFA should have a photonics radar instead, which should come in by 2030, instead of simply paying to make something that the Rafale will also come with. That delay will allow us to manage funds properly as well. I think the IAF is thinking along the same lines, hence the delay.
Western media has simply confused Stage 1's cancellation with the entire program, something that's common knowledge on this forum at the very least. And being here, you already know that no one's gonna be buying the Stage 1, neither India nor Russia.
