So they're slow walking the airframes destined for the "2nd stage" engine.
What this tells me is that there's going to be no easy, "swap out" for this new engine. That is, using the same airframe... they just install the new engine and go flying. Now of course it's going to take testing to get it right, but it also suggests it's a lot bigger deal than perhaps previously thought. You didn't see the US Navy stop producing TF-30 powered F-14's, while awaiting more powerful motors. There wasn't a new inlet design that needed to be put into place, etc.. No, you had some of those same aircraft swap the TF-30 for the more powerful GE F-110's when it was ready.
I don't get the sense it'll be that easy on the SU-57. Which means a lot longer test period, and holding off on any substantial airframe buys until the new engine is truly ready. We already know the inlet design needs work, at least from a stealth perspective. Dealing with that might be small potatoes vs. airflow issues given the much greater thrust and supercruise they're trying to accomplish. 2025 might be do-able, but I think 2027 - 2030 is a lot more realistic.
Opinions?

They will make something of it, there's too much national pride at stake. And Putin's a big fan, so that needs to be taken into consideration as well.
But as a mass produced item it's doubtful, in fact they said it wouldn't be. Then left the door open for maybe it would, if "the rest of the world" catches up to their SU-35S, LOL. But honestly, by the time the engine etc is ready it'll arrive at 5th gen status, once the world is fielding 6th gens...

There will not be new inlet! It will have radar blocker,which is mentioned in couple of Sukhoi patents. Radar blocker isn't present with 117 engine because it is part of new engine. New engine is also important for rear RCS because its nozzle have much smaller RCS and probable smaller IR signature then classic nozzle( new one is fattier plus have something which look like cooling ports) :

They are gonna use the most sophisticated Russian tools to get that thing going no matter what we say, think or do.
Some random pliers, some torn screwdrivers, some rusty hammers, some rolls of duct tape and a gallon of superglue.
Then paint the thing pink and call it 7th gen to spook the crows. (Who will drop out of the sky laughing anyway).
While the levcons are actually a good idea? ? ? My barn doors have better hinges.
But?
As usual, they'll shine at airshows.
(Replacing molten engines every time they put air in the tires.)

This may sound stupid for a lot of people but does the Su-57 have RWR?
I went through the avionics of the Su-57 (granted it was only Wikipedia) but I couldn't find it.
The Himalayas system is ECM? can it perform RWR? If not, then that means that the only long range detection method of the Su-57 is via Active radar

On a fifth-gen fighter the line between RWR, radar, ECM and IFF is blurred, since an AESA can perform any of those tasks. The SU-57, by reports released thus far, will be no exception. The electronics probably won't be quite as compact and efficient as those in the F-35, but by the reports thus far, they are designed to work in broadly the same way.
That said, RWR is of fairly dubious value for long-range targeting, at least against airborne targets.

Given Russian electronics inferiority, it is unlikely the Himalayas is a very good ESM either; it is likely equivalent to Western 1990s systems at best, but probably more similar to 1980s systems.

2000s if you look antenna technology (AESA to be precise). I don't know any western ESM which use AESA antennas in 1990s, maybe I am wrong.

The sensitivity of the antenna is more important than being AESA or not, as is the other components. It uses an Elbrus processor for example.
I freely admit to having little knowledge of these topics, but to the best of my understanding, Russia is still decades behind the West in related eletronics fields.
I also admit I probably exaggerated the relative technology of Himalayas by a few decades; access to Western technology has allowed the Russian technology base to catch up a fair bit since the end of the Cold War, just not completely.
