I mean the only truthful thing to say is that Su-57 is unproven and an unknown factor. At least to my knowledge

its getting some attention now, some stopgap upgrades before later block F-35 and NGAD become operational.
but mostly dropped for cost. F-22 is not a cheap jet to buy or fly
Manufactured =/= retired though. Last T-80s were probably made from the late 1980s before the soviet union collapsed, yet it is still being upgraded right now
Same goes to the F-22, recent plans for upgrades includes iirc HMD and Link 16 transceivers. Probably even better radar and EOTS

Su-57 is not stealth, but it is an aircraft of substantial size, lighter than an F-22, larger than an Su-27, with the RCS most similar to Rafale.
It’s an impressive jet for not being stealth.
It gets a lot of hate cause my American media claimed it to be stealth when it wasn’t.
Also @Busheedoh , F-35 is a single-engine stealth aircraft, and the future is single-engine stealth aircraft, for which there’s more progress to make.
Korea will likely make the next jump, but the jet to bring forth far more stealth than them will be one that uses a singular moderate engine, such as a Saturn type, Pratt & Whit 220 type, or General Electric 129 OR 414 type.
And yeah. F-22’s radar is a first generation AESA.
Either way, all countries are behind on stealth fighters even my own America. Likely due to the navy requirements more than anything else.
what are you talking about?

I don’r think it’s fair to call it not stealth when no one really knows actual RCS figures (because you know, it’s classified).
It’s probably not as stealthy as American stealth, but it’s still a stealth jet

Not stealth according to what? Stealthflanker’s simulations? YT comments?
The reasons given for the “not stealth” have all been debunked. Russia has done flat nozzles, faceted IRSTs, full S-ducts, radar blockers, RAM, RAS…Soviets were studying stealth as far back as 1983 with the S-22. Those arguments for “muh F18 RCS” couldn’t be buried any deeper.
I guess LM doesn’t know about stealth designs either. Imagine mentioning 0.1-1m^2 for the KF21 
Also, KF21 RCS simulation by StealthFlanker/Aircraft101 for the frontal arc:
About 0.7m^2 frontal. So, again, all that help from LM, on a plane that looks a lot like a F22/35 blend. Is it LM that doesn’t know stealth, or is it that internet data is unreliable?

How much help do you think LM had in that aircraft?
I have no idea, I’d guess probably a lot since South Korea hasn’t been dealing with stealth technology since the 1980s like the USSR/RU is, but that’s irrelevant, I don’t believe in those simulations for starters, my point is, see how easy it is to throw some make-believe numbers from the internet, treat them like the Tablet of Stones and just deny any incoming arguments?

Hope one day both SU-57 and F-22 fight each other to prove who’s the best whoever win is better yeah seem it the only way to prove it
I don’t care really much about this whole “muh aircraft”. This post was made for Ragebait. That being said I think you should understand the KF-21 is Korean. The only thing the US did for Korea in it’s development is provide technical data.
My point was that it’s foolish to believe some amateur simulations on AF101 are telling us the truth, or that Sukhoi would put real RCS numbers on a public patent, or that a YT video is telling us the real RCS for a Korean 5th gen. I’m not saying which one is best either, I’m saying the reasons for discrediting Sukhoi are coming from disproven/bad arguments.
KF21 is probably a very capable aircraft, as I don’t think for a second SK engineers are idiots, and neither are the ones at Sukhoi or LM or Northrop.

Rafale have bigger RCS what Su-35 he he
I really hope this is bait, because you don’t seem to understand the KF-21 at all.
KF-21 as it stands now is not stealth, and isn’t intended to be stealth. In fact, it is an agreement with LM that a certain production number of it will only be 4.5th get aircraft with limited low-visibility features. (Can’t find the source, might be false.) It is planned for Block 3 to introduce a fully stealth design with internal weapons bay and flush sensor elements.
Current KF-21 shouldn’t be compared to an F-22 or F-35, but rather something like a Super Hornet Block III.
You have mixed everything into one pile…
- The Su-57 is an air defense fighter…
- F-35 reconnaissance and strike complex…"Due to the ability to penetrate enemy territory using radar with a low probability of detecting radiation and passive sensors, the F-35 will not operate in proximity to a modern, so-called fourth-generation aircraft. Instead, it will fly in well-protected enemy territory, transmitting the exact coordinates of targets to a conventional aircraft equipped with weapons with a range beyond the enemy’s reach. The F-35 aircraft is designed so that an electronic attack (jamming, misleading the enemy, using disorienting interference and energy beams) would be as simple as an attack using conventional weapons. "…
However, from the experience of combat operations, it is known where the concept of using the F-35 is rapidly changing… «Увеличивает дальность и эффективность поражения»: США провели испытания истребителя F-35B с ПКР AGM-158C LRASM

It won’t happen!.. Both the F-22 and Su-35 are aircraft of the same class (primarily air defense fighters)…
The F-35 is different…!

Please tell me what exactly in this garbage article proves the image to be wrong ?
Author is grasping at dead straws and jumping into conclusions out of pixel counting …
You have a lot to learn my friend if you believe that you can debate me with teenager blogpost tier of material for support to your arguments !
What are you supposed to be showing with this ?
