Tagging you, my friend.
F-35 uses GaAS AESA. APG-81 has RCS of 1 at 150km
SU-57 uses GaN AESA . N036 has RCS of 1 at 400km
GaAs and GaN are useless parameters to highlight - what does this even prove? This sounds familiar actually - all those mouth-watering marketing terms you read on the box of a shiny new motherboard...
Refer to this post:

Russians consider 3m^2 RCS as the standard reference point to highlight detection power of their radar systems on brochures for the public.
A (decent) airborne AWACS system is likely to pick on a jet fighter having an RCS in the 0.1 - 1.0m^2 range at around 200 KM mark.
RCS TABLE FOR REFERENCE
Ever seen the radome of a modern AWACS system? massive to say the least. Think about how many T/R modules it would be packing within.
N036 has RCS of 1 at 400km?
NOT EVEN CLOSE
"Compared to previous Russian radars, the N036 will likely be more capable in most aspects – that’s what you get from an AESA radar. However, this is an area where Russia is significantly lagging behind the West. Till date there’s not a single operational AESA radar on any Russian aircraft despite Russian manufacturers marketing their AESA radars from over a decade now. Even the latest Mig-35s that were sold to Egypt actually had Zhuk-ME MSA radars. This clearly shows Russia’s lack of maturation in AESA radars.
I’ve seen people confusing Su-57’s side-looking arrays (N036B-1-01) with the main (N036) front radar and considering them as a single radar, which they are not. The X band side-looking arrays have a different Field of view with respect to the front radar, except maybe a negligible overlap. Therefore, you can’t actually “fuse” data from all 3 radars as they can’t see the same target at the same time. Sure, the data from all 3 arrays are likely to be processed together.
Also, the N036/AFAR is using GaAs T/R modules as per the manufacturer (ФАР с ЭУЛ) and not GaN modules as what many propaganda sites would want you to believe. Honestly, I never saw any genuine data to suggest that any Fighter-borne radar uses GaN AESA radar today.
Coming to those L band arrays, contrary to what many believe, those are not radars. There’s not a single piece of data from NIIP (manufacturer) to suggest that those leading-edge L band arrays function as ‘radar’ nor is it technically practical. You may refer: PAK FA and L Band arrays. Those L band arrays are for IFF and possibly part of EW suite. Its current setup would be very good at IFF function.
Many don’t realize the level of difference between different generations of AESA radars (in terms of operational radars). This is the difference between a 2nd gen. (APG-77) and 3rd gen. (APG-77v1) radar which have T/R modules from APG-81.

Range is just one aspect.
So how good will be Su-57’s 1st gen. AESA radar? Probably better than any radar on a Russian Fighter. It’s having ~1,550 T/R modules. So may have some minor advantages compared to AESA radars with smaller radome (T/R modules) like on Gripen, Rafale, etc. Any comparison with APG-81 (~1,672 TRMs) is pointless."

Case closed.
( N036 L-band radar array will alert its pilots to the general vicinity of enemy 5th generation stealth fighters such as F-35 )
EMPHASIS ON THIS PART:

Even the most powerful of current generation Russian VHF radar systems will not unmask F-35 from decent enough distance:
Declassified information
-- SU-57's Passive sensor IRST ( infrared search and tack system ) .... infrared camera that scans a head of the aircraft up to 30 km and since it does not emit a signal the enemy can not detect that you have them locked up
( potentially helping it find stealth aircraft at close ranges )
F-35's passive sensor network have no peer in the world in the domain of jet fighters yet. FYI:
https://defence.pk/pdf/threads/unde...-35-jsf-for-the-dummies.472240/#post-10935637
To give you an idea about its detection sensitivity:
[1] That rocket was in motion about
800 MILES away from the position of
this F-35 prototype jet and the latter's DAS network easily locked onto it, and this is an OLD TEST (2010). Imagine the sensitivity of DAS network in its current form...
And as I pointed out earlier, F-35 have an excellent sensor fusion architecture: AESA + RWR + EOTS + DAS + CNI + HMDS
1. DAS notice something in a particular direction (360 degree coverage).
2. The sensor fusion hub directs EOTS, AN/APG-81 and Barracuda towards the initial
contact.
3. EOTS zooms in on the
contact to classify and ID it, and attempt to range it with LASER.
4. AN/APG-81 does very narrow search towards the
contact to get radar information about it.
5. Barracuda listens to emissions coming from that direction with parameters that match best the type of target (if known).
6. The sensor fusion hub collects and analyses all the information coming from all the sensors and generates and maintains target tracks by tasking the sensors depending on target and situation.
Respective detection range of each sensor system is NOT TO SCALE - refer to
[1] above. And F-35 offers FUSED VIEW of the
battlefield to its pilot.
And Su-57 is
NOT a VLO design per Western standards (see
RCS TABLE FOR REFERENCE above), so expect it to be picked on earlier and engaged earlier...
-- Russia has advanced electronic warfare capabilities and SU-57 is equipped with digital radio frequency memory (DRFM) jammers that can blind the air to air missiles active radar seeker
See the top response in this link:
https://www.quora.com/Is-it-true-that-an-SU-35-can-easily-jam-an-AMRAAM-120D-AIM9X-making-an-F-35’s-BVR-capabilities-less-effective
AIM-120D AMRAAM incorporate multiple guidance mechanisms in its operation:
- and feature both
HOJ and
HOBS capabilities to get around potential jamming.
-- SU-57 has two engines with more agile characteristics, higher ceiling, impressive ferry range and more ruggedly built than the F35
Pointless observations. Refer back to this response:
https://defence.pk/pdf/threads/turk...ighters-to-ankara.613126/page-5#post-11363519
-- F-35A has no Thurst vectoring control ( TVC ) , even F-22 has 2D thrust vector jets ..... but SU-57 has 3D thrust vector jets which the US Fighter Jets do not have
Pointless observations once again.
Su-35S also have 3D Thrust Vectoring, and yet:
Russian design philosophy is different from American, and conventional black-and-white comparisons of the characteristics found in Russian and American fighter jets are
ill-advised.
-- The internal payload = F-35A : 4 air to air missiles ..... SU-57 : 8 air to air missiles
Su-57 is relatively bigger bird and its internal payload capacity is SIX - same as in F-22A Raptor.
However, this is not much of an advantage to highlight when up against an F-35 variant or F-22A.
so Turkish design cockpit , electronics , mission computer , IFF system , self protection electronic warfare suite , national data link , network centric warfare and weapons can make SU-57 more dangerous under the control of crazy talented and well trained Turkish Pilots
Sure.
