Major Update "Leviathans" - Rumor Round-Up & Discussion (Part 3)

the su-57 has actually a smaller wing span than the Su-27

and is actually not that much bigger than the F-22

even in the 2nd there are many similarities and its clearly copied in at least partially. if you have a front end photo that would be nice

Don’t talk about Iran especially not so close to the thing lol

That is far from modern, late 1980s standards at best.

U still get the flanker vibe though, especially when flying. The way it flies is soooo nice.

Yeah Ik there is definitely similarities but pretty much down to the tail and the connection of radar. Based off Y-7 and a new two side AESA. From what I can see this is prototype of a prototype, just to test if the airframe works. Cause seemingly the wings don’t yet fold, likely modified Y-7.

If the F-22 was bombed on an air field, that would be indefensible and would yield the same reaction. Seriously. Also, the Su-57E being “exported” are few in number, if they are being exported at all. Not to mention the fact that over a 1000 F-35s have been built as well as over 150 raptors… while the Su-57/57E have maybe 3 dozen or so airframes in service.

2nd of all, even among 4th generation fighters, when was the last time there was a confirmed dogfight? If the only good feature of a “stealth” jet with an RCS estimated to be .01 to 1 m^2 is that of its dogfighting ability, it would be dead on arrival to any warzone. If Dogfighting is such a in demand figure, i wonder why the fighter mafia’s red bird never took off…

The F-35 especially has a better radar, better sensor fusion ability, better situational awareness, better networking, and to put the cherry on top, the advent of high off bore sight Fox-2s makes the dogfighting less important. Im sure you buy into the idea that the F-35 cant beat an F-16 in a dogfight-- which is untrue. While a Clean, minimum fuel F-16 may give it a run for its money, the F-35 in every other circumstance was shown to wipe the floor with the F-16. Not to mention its overwhelming stealth advantage of the F-35 over the Su-57, the only time the Su-57 would have the clear advantage if both jets are in a dogfight with cannons only. About the F-22, the upgrade plans for the raptor aim to put it on par with the F-35s abilities sensor-wise.

Third of all, the Su-57s visual similarities with the YF-23A are very real.


The nose cone, the cockpit, the recantuglar s-duct tucked under the wing, the omni directional stabilizers, etc.

I agree that the Su-57 is not a 1:1 replica of the YF-23A, however it would be dishonest to say that the designers of the PAK FA and more refined Su-57 never drew inspiration or design cues from the YF-23A

What about the modern domestic Iranian SAM and -ESA radars?

its not even that high, in 2024 it was estimated only 14 production Su57s were in service so unless russia has tripled their fleet in a year when they couldn’t in 15 years its a little over a dozen

Mostly relatively short range, like Pantsir and Tor. Also I doubt that PESA systems are very good, as well as the fact that stuff like Osa and Strela would be out of service if they are ‘good’. They are to me 1990s standards for AA systems.

Bro I thought they fixed 405 bug.

from what I have read PESA are marketed as being able to detect stealth aircraft but experts have debated that in reality they would probably struggle

Estimated. Pretty bad to take seriously cause they are normally on the safe side as to not exaggerate the threat.

Well that is still a PESA, u wouldn’t use it if u have an AESA.

the highest estimate was 22 so not even 2 dozen so still just over half of what you said lol

Estimate, again, nothing reliable, especially coming from NATO sources on a hostile nation’s top secret. 22 is very much on the safe side and when mass production starts this will soon jump. The number estimated for J-20 for example jumped from 2 dozen in 2016 to more than 200 today, with estimates of as many as 3-400 purely by tail number.
Also what did I say on numbers?

Cool, definetly going to watch that!

the Su57 has struggled to get into mass production for years so its quite the jump to assume they can, and thats still a 9 year gap from a couple dozen to 200 for the J20, this was from a year ago I highly doubt that a nation that has sturggled to produce a dozen Su57s over the last 15 years has suddenly been able to produce several dozen in a single year

they didnt struggle, they waited for the AL-51 to finish develpoment

That was in fact 2018, but there is a lag time cause u need to analyse data from previous years. I would say Su57 RN is around 30 or 40, maybe 50-60 accounting prototypes.

they did, the original plant was to small and ill equipped to build 76 by 2027, which resulted in a new line being built, the higher estimate was they could build 20 in 2024, compared to the say 110 F-35s that were built in 2024
