IRST is much more limited in range then radar, as for ECM, it is not impossible for an AESA radar to burn through an aircrafts ECM, not to mention many missiles have the ability to simply home in on a jamming aircraft, thus why the f35 has a deployable ECM device that is towed behind the aircraft if it is ever acquired by an enemy aircraft
The ball never reflects light back to the radiation source, it will always distort the light.That is, the reverse radiation will be strong
Burn is a big word.It all depends on the power of the radiated source.And how does the Radar cope with such
What you’ve stated about stealth suggests you’re reading wikipedia incorrectly. The truth is much more complex than anyone has stated. Russia’s Su-57 is no doubt a 5th generation fighter proper and fits in an entirely different (better) category of stealth than anything else that isn’t gen5. There is low observable (LO) (F/A-18E block 3+, Rafales, KF-21, etc)… and then there is ‘very’ low observable (VLO) which solely belongs to F-22, F-35, J-20, Su-57 currently. I am aware of others but we are discussing proper fighters.
The ranges an Su-57 will be found frontally on radar will be low enough so as to alert both aircraft to each others positions by other sensors prior to any possible radar acquisitions. This is sufficient stealth.

First of all, no im not reading off of wikipedia, as most of the details im citing are common sense based off how light reflects off of objects in the microwave spectrum, and the fact that you have made several claims that are factual garbage such as : “The ball never reflects light back to the radiation source, it will always distort the light.That is, the reverse radiation will be strong”., which is physically impossible mind you.
second of all it has been proven through several studies that the shape and material of the su57 is outright unstealthily in its current iteration (see weapons bay not sealing, engine fans being visible, and subpar materials like wooden screws
Much of what you have ‘stated’ to counter my points are old talking points by propagandists before the war trying to give off a ‘russia strong’ image, the su57 is at best low observability, and at worst a non functional vanity project that has never been tested on the front lines of any combat scenario
I didn’t say any of that
This is all nonsense. The F-22 has worse exposed fasteners of similar type all over the cockpit area. This isn’t a huge concern like you think. All of what you have stated is either ground models, non production, or otherwise not a flight worthy serial aircraft afaik.
Everything in your last post is exactly that. Post specifics and I’ll debunk them.

You can learn more from here
1, both of you have identical user icons so my b,
2, the su57’s most famous images of the exposed screws where when it was airborn, aka flight worthy serial aircraft, as noted in this image, the most famous one
good image on the su57’s engine ducts,
you can see the compressors blades, not ideal for stealth

And you can take photos of the F-35 and F-22 prototypes

yes you can, neither have exposed uncoated screws, nor are their engines exposed from the front

There are screws and rivets sticking out.That’s why they are prototypes in order to identify imperfections and eliminate them

no other stealth aircraft, not even the j20, did that during their prototyping phase, the su57 STILL lacks any form of covering for its engines, it entered production in 2022 as per russian sources
11 flight prototypes were built for the Su-57 and each was designed to work out some tasks.Engine protection is provided by a radar blocker
do you have a source of whether or not that grate is on any models?
think this might be the only image on the internet with the engine mesh in place, earliest i could place this is from 2020, and while im sure it might be effective, they would be better of simply retooling the whole engine like the planned su57M models, as this mesh will still reflect radar, if by less
Pre production PAK FA T-50, production airframes are redesigned and have actual ram coating and proper panels. The same goes for the radar blocker in the intake. F-22 has similar ‘issues’.

These are T-50-10 and T-50-1 prototypes
