Glad someone else is as skeptical of side bays in Su-57. Drop away sheaths are possible but even then, it's not simply an issue of does the volume in that space exceed the volume of a sraam. Missile require much more room for pylons, launching and control mechanisms, not to even mention hinges if they are doors or even mechanisms if they are drop away sheaths. Unless they've made super tiny sraams, su-57 does not have side bays. It also is unlikely to be able to carry 6 mraam as they claim. I have similar doubts about J-20's main bay carrying 6 mraams.

Many fanboys are still delusional about this to this day despite not having seen one official source confirming these claims or any actual photographs showing the ability. Unless China and Russia miniaturise they're mraams, their respective 5th gen fighters will carry fewer missiles than the raptor. This hugely disappointing for those of us who are cheering on China and Russia in their attempt at matching US military capability. China's J-20 is far closer to an F-22 competitor than Su-57 it seems on the surface. Having said that, I wonder what those protrusions are for. My bet is spacing for existing electronic warfare equipment, radar, or future modifications for those items or others.

Since he doesn't require official proof for these claims, then the rest should be treated similarly.

Very difficult and every cm count in the weapons bays.
But here good site and Russian wiki also 8 HPs for 8 AAMs, max 4 x A2G weapons of about 0.6 -0.7 t max in fact 1000 lbs bombs.

Seems possible Russians have AA-12/R-77-1 do 42 cm with fins small

Chinese for J-20 have PL-12 and 15 much more big do 67 cm so 4 make completely sense in more Huitong post 4 internaly and necessary a new to have 6...

Exactly, and while I'm not going to discount that each bay "may" carry 3 staggered, for a total of six?? I'd have to see that to believe it, may be true, but even that is really cramming them in there??

If they did that, then they wouldn't be able to launch those missiles while turning. Two medium missiles in each of the Su-57's two bays is already a tight fit. Those areas are TINY. J-20's main bay seems larger due to adjacent positioning but they do also look a bit wider and deeper than Su-57's so maybe will be able to fit some larger missiles in them as well. Most likely 4 MRAAMs for the time being until smaller ones are fielded. PL-15 doesn't look thinner than PL-12 to the point where J-20 can fit 6.

So far it would seem to us, the under-informed speculators and appreciators, that the Su-57 is a very compromising 5th gen fighter. This could explain why the RuAF and IAF cut orders, if the IAF will eventually induct any at all. If the Su-57 is really all that the fanboys cranked it up to be, they'd all be ordering hundreds and many air forces would express interest in acquiring it or becoming future partners in developing their own projects. Japan, S.Korea, Iran, Turkey... they can all afford to join up and improve their own domestic 5th gen projects. Instead S.Korea went with Lockheed Martin. Japan is happy with F-35 and most likely won't continue with Shin Shin. Others are all considering partnering up with each other but none with Russia or India (with their AMCA project). Sure we could say that's because Russia isn't selling their top line fighter immediately. But they've been happy putting just about everything brand new on the market and the factories do need the scale to bring costs down so we're not talking about Armata.

Exactly how many Su-57s have the RuAF ordered? Was the last official word something like 12 with more Su-35s to supplement? They're certainly not bankrupt and Russia does still have plenty of funds left for these procurements if they wanted to. Maybe they know as the technology currently stands, building many of these are a waste because they provide little improvement over Su-35 with huge costs. They may be waiting for KRET's next gen sensors, next gen missiles from various developers, and manufacturing technologies to make this a more LO fighter before putting all their eggs in.

If the wingspan quoted online is accurate at 14m. Each bay is at most 1.2m wide. With expandable fins of R-77, a fixed minimum diameter of 350mm for each missile. This means each main bay cannot fit three of today's R-77s. Three R-77s side by side would be around 1.05m, giving only around 15cm for gaps between each of the three missiles and the adjacent wall clearance. Assuming even gap, this would be only less than 4cm for each gap and clearance. There's no safe way of ejecting those missiles while turning with that kind of clearance. Bay is not deep enough to double stack or orient the missiles according to fin geometry. Su-57 should have more shallow bays given the thickness of the aircraft in that section. Why the designers didn't go with a fuselage similar to LM designs is strange. Perhaps costs were such a big issue they only had enough for new avionics and electronics on a stealthified flanker with internal bays. This is all not even considering the thickness of those doors which would realistically take out those gap margins completely because they certainly cannot be inward opening or sliding doors.

This is very cool. But I have to question what Moscow Mayor is doing with a secret military project at the Federation level. Is it "out of his jurisdiction" sort of speak
I wouldn't say it is totally out of his jurisdiction.

If it is a highly secretive project, he surely would not be allowed to visit. But I think at this moment, the new engine project is not really a secret any more to bar the mayor. UEC has made it public, showing a tip of the nozzle is not leaking anything. BTW, the plant does pay tax to Moscow, so the mayor should care a lot of the plant's performance and needs. The inspection by him at an appropriate time is normal.

Putting such a list of countries' supposed "turning away" from collaboration/purchasing Su-57 is really weird argument to support your point. Who said Japan, S.Korea have ever thought of turning to any non-western supplier? Since that is an impossibility in our life time, putting up the two as an argument is "blow into the air" i.e. "an assault on a position that nobody occupy". Even Turkey's chance of approaching Su-57 is non-existence for the moment, and slim in the next 10 years because Turkey has participated F-35 program long before PakFa surfaced.

Yep, he's NEVER wrong,, he can not admit he doesn't have a clue?? after all, he was married to a Russian woman, so he must know everything about Russia.

anyway, thanks for trying,,,, its apparent after looking at photo's with the gear doors open that SU-57 does not have any side bays, there's simply no room...

that thin fuselage has likely caused them other issues as well, but even the main bays will end up being rather shallow, one reason they had to move the engines well outboard,,, which could cause a problem if you "lose" an engine with those tiny verts?

I must have missed something. What photo are you talking about? By the "gear doors", do you mean the main landing gear? Or something else that I missed?
