air sells a crapton of premiums
I find it funny that people believe that the ”L-band radar” can be used to detect targets at long range (100km<). If you know how radars work you would realize that it’s physically impossible with a radar of this size.

that is true russia didnt use a serpentine inlet or s-duct because (if i had to guess) they didnt want to impact flight performance at slower speeds
but at high speeds and BVR the copressor blades arent visible due to the air intake doors that are used to regulate the speed of the air entering the engine
this reduces RCS significantly in a BVR scenario where it matters the most, once someone gets close enough for both of you to slow down enough for the intel ramps to be open stealth dosent matter anymore because you are likely within visual range
that is true we cant because it is highly dependednd on radar frequency but there are radar simulations out there that will atleast give us an aproximation or something to compare it to
edit:
that simulation has been made by stealthflanker and iam going to attach the original link to it once i find it

I wonder what assumptions Stealthflanker made about the Su-57, it really differs from other simulations I’ve seen. I would like to know more about the model he used.
the air intake doors closed
and the IRST being covered like in this picture:
instead of it being open
it can be open and closed in flight
Im aware of this, I found some of his posts on a forum. This is the model he used for the F-35 btw. I don’t think we can compare the Su-57 to the F-35’s RCS with whatever this is.

peak f-35 model…
I did some more digging, the Su-57 model Stealthflanker made is apparently very low poly/resolution without many details so you should take the RCS estimations with a grain of salt.
just like i do with every RCS values
but what iam saying is that the RCS of the Su-57 does not seem too bad after all (in BVR conditions)
where it matters the most in my opinion

Yeah it’s not as large as people claim it to be, but not as small as other people like to claim it to be. I would sayings decent but not F-35 level. F-35 should not be compared to Su-57 really, same goes for F-22. F-22 is a project from 30 years ago and the F-35 has a different role than Su-57 and has a way, way bigger development budget.
The Su-57 is unique, in that it didn’t sacrifice speed or maneuverability for stealth. It’s stealthy enough to not be seen at long and medium ranges, so it gets up-close and personal, forcing a merge or evasive action from the slow and flying bricks like F-35. When the F-35 finds the Su-57, it’s already too late because the Su-57 can sure as hell spot the F-35 too.

i also think that raw flight performance might be becoming more important in the future with stealth becoming better and better
the better stealth gets, the shorter the engagment distance will be, meaning that jets might be forced to do dogfights again
