as always it depends on the radar band and the aspect
in general the Su-57 should have a way higher combat radius than the F-22
the F-22 might have really powerful engines but they are awfully inefficent
the ammount of weapons they can carry should be about the same (tho iam not too sure about how much stuff the raptor can carry externally)
internally the raptor has 2 more radar missiles if the Felon only carries 4 r-77M’s internally (i have seen ppl claiming it is able to carry 6 internally tho and then it would be equal)
flight performance wise the Raptor should be great at BVR with its high speed and lots of thrust but in a direct dogfight it might not be as good (similar to the F-15E lots of thrust but really heavy)
on the other side i would expect the Felon to do worse at BVR (against other 5th gens) than the Raptor
against anything that isnt stealth it should do great due to it being able to carry the R-37M
(a big af missile with lots of range ~200-300km when launched from Su-35)
the Su-57 loses a bit of performance at long range engagements but is better for closer ranges (anything under ~100km) and should do better especially in 1 on 1 dogfights due to the following points
large wing area (lots of lift)
unobstructed air intakes (low channel loss)
3D thrust vectoring
a LDIRCM system to defeat IR missiles (similar to the Mi-28MN ingame currently)
i dont know to much about the radars on both the Raptor and Felon but the predecessor of the Su-57 radar, the IRBIS-E, is claimed to be able to detect a target with the Raports RCS at around 80km
but the to me it is quite interesting that the Su-57 has more or less 360° radar coverage
TLDR:
the Felon will most likely be better at the ranges relevant in war thunder due too how small the maps are
not on any stealth aircraft
the last leak was a Harrier manual
Officially the tail boom antenna is part of the ECM system. Technically it utilizes arrays of the N036, but whether it actually works as a rear-view radar is a different story.
I wouldn’t say it’s completely out of the question that it could work as a radar, but there’s a less evidence to support it at this point.
The rear part (L402) is “just” an adaptive ECM Jammer. The only actual Radars the Su-57 has are the main N036 and the two side facing (and most likely situational awarness related, as each only has ~360 T/R modules) N036Bs.
L-Band side arrays can already be found on many Flankers (e.g. Type 4283) and various NATO aircraft, iirc their main propose is “improved” long range detection, IFF and (rarely) communication - i.e. its not able to provide a lock, but only low accuraty approximate coordinates of a Target, which are then feed to the main Radar and EW suit.
In terms of gameplay, the Su-57 will hardly differ from something like the Su-30SM.
Seriously, the main differences are the AESA radar and a slightly different flight model. Unique missiles for it, like the R-77M, were shelved and never fully developed. Its stealth doesn’t help much against PESA/AESA radars, and the fact that it can perform a ‘Bell’ maneuver won’t save it from AIM-120s or Meteors, and so on.
In real life, this comparison would be ridiculous, but we’re dealing with a game and despite all the “realism” claims, it’s very arcadey. Because of this arcade nature, the gameplay difference between the Su-30SM and the Su-57 is minimal.
The Su-57 has much more modern weaponry, much different than what we see in game now. It also has a LDIRCM which gives it the ability to completely ignore x2 Fox-2 missiles being fired at it, it has stealth properties, maybe this blew past your head at Mach 10 idk.
It’s not like the r-77-1 is a bad missile for bvr, it’s roughly on par with aim 120a and is only worse than aim-120c5 in terms of range, while having better better time to target than either amraam model.
they can simply add su-57 with 6x external r-77-1 missiles if they don’t want to give it r-77m
