Since 2025, only the Su-57M with AL-51F1…
The new engine has a Composite inlet guide device (VNA), the composite VNA on the new engine does not negate the presence of a radar blocker. On the old one, this VNA was metal with a radio-absorbing coating… Показана снижающая заметность решётка в воздухозаборнике истребителя Су-57

The addition of Side antennas is actually interesting, dk how practical it is irl. But isn’t the L-Band antenna only for IFF?
Also anyone can ELI5 how an AESA IFF antenna works? Apparently it was integrated in the Su-35 and 30SM2
“This module is not confirmed yet”
I’ve read that as well. The leading edge L-band being for IFF, not for practical detection because they’re supposedly low-power in a system (the aircraft) that already has to dedicate power to many other electronics, especially the higher powered forward-looking radar.
I have not seen brochures or more official sources confirming that information, though.
That its mostly on Su-35s. Su-57 use one more advance. Assessing the Tikhomirov NIIP L-Band Active Electronically Steered Array This paper is about the Su-35s L band radar. Yea its a bit underpower for a L-band. But it can work and seriously why would some manufacture build a IFF so big and complex? that just don’t make sense.

Temeraire reply: I’ve read on those antennas working for other stuff as well (interference for satellite, etc.).
My personal opinion is that those modern systems probably can divert power to whatever is needed, as needed, to work at 100% power (or over) while some other less important system runs at a lower power. Of course, that’s speculation on my part, but if I were designing aircraft systems nowadays, it’s certainly a route I’d explore. Sounds kinda obvious but then I remember companies only started putting decent radar symbology and color coding when it was already F22 days.
Dude posting meme above:
As for the YF23 meme. Yeah, according to sources worth listening to, it was a stealthier design. And it’s not like there weren’t changes made from the YF23 to F23, we have some unclassified drawings and there were lots of changes adopted – DSI included, which we would only see from LM in the F35. The F22 used splitter plates for boundary layer control, which is known to be a worse solution for stealth.
Besides, the ATF LM/YF22 also had problems and applied several solutions proposed by the YF23 for the production F22.
I won’t dwell on those because it’s off-topic

That its true. Usually radar work on “X” KW but they have a “Peak” KW. The Advantage of GaN over GaAs. Its that Its have higher Peak and produce less Heat. Heat being one of the mayor problems in these system. That paper even talk about it.
Speculative IMO. Just like Su-35s use a Hybrid PESA as main radar and AESA GaAs on wing. Su-57 use a GaAs AESA as main radar with GaN on the wing. There are image on internet on 4283 (Su-35s) and N036L and they don’t look the same.
This is some Russian inteligence psy-ops meant to bait out “sekret dokuments”.

The only person making false claims here is you bro, because you can’t accept that the F-22 isn’t as good as the US says it is

its better than the US says it is. official figures for supercruise are 1.5+ on USAF website but pilots have hit 1.8+ without afterburner.

Got a source for that?
https://www.af.mil/News/Article-Display/Article/135233/general-jumper-qualifies-in-fa-22-raptor/
USAF chief of staff “exceeding mach 1.7”
other pilot have said 1.8-1.82 iirc but i cant find the direct quotes

Ok, interesting. Thats from 2005 too.
same year as F-22 introduction. its also why its F/A-22 since they wanted to really show off its a2g ability (but as we all know now, they changed it back once it entered service)
now, could you find me a source stating that Su-57 can even supercruise? and if it can, at what speed?

Depends if you want a source from Russia or a source from another country:
Can apparently supercruise at mach 1.3
oh and this too:
" A major driver of the Su-57’s performance are its two engines. The Saturn izdeliye 30 engines are each meant to generate between 24,054 and 35,556 pounds of thrust, with the high end in the same territory as the F-22’s F119 engines. These are meant to drive the fighter to speeds of up to Mach 1.5 in supercruise. Unfortunately the izdeliye 30 is undergoing difficulties, and as a result the first twelve of Moscow’s new jets will be powered by a pair of Saturn AL-41F1 afterburning turbofans producing a combined 65,000 pounds of thrust, the same engines that power the Su-35."
show me where i said anything like that
and again, here you can see proof of what i actually did say to disprove pro russian fake claims;
heres some proof from my side
imagine a “5th gen” with worse supercruise than a eurocanard lol
