Izdeliye 30 will have supersonic burning detonative resonated afterburner (according to UEC chief).
Armament will be 4 items in 2 MWBs + 2 items in FSBs (1 item in each of 2 FSBs) - 6 total for Stage 1 airframe.
It is possible that items number (for Izdeliye 180 MRAAMS and similar size) in MWBs will be increased to3 in each bay (which will give us 8 in total with FSBs) for Stage II airframe. But it is unclear for now.
Any way we will have only 2 big items like KAB-500 or Kh-58UShK in each MWB due to their sizes.

All the systems are operational (as LRIP starts next year).
However it has so unique abilities, unique avionics work modes and completely unique weapons that it needs significant time to test them all and then compose airmen instructions and tactics to give VKS the full understanding on how to use it properly.
And of course, you cannot compare medium (Rafale) and heavy (T-50) fighters from different generations. It is some naive :)
LRIP next year? why not.
As F35 shows, after LRIP there is a long road to induction and war ready.

Americans wanted to cheat the fate sending really a premature aircraft into LRIP.
That's why they have so much trouble because they need to build new planes and rebuild/rearrange already built ones in parallel to this process.

What are the advantages of such a setup?
Supersonic burning process gives us rather higher gas pressure in afterburner and thus rather higher afterburning thrust especially on high altitudes.
Detonative resonated burning process gives us the highest possible fuel efficiency due to full fuel burning without Serum remainings. And this type of burning is rather more stable and laminar than usual subsonic one.
This is in fact a technological revolution that makes us much closer to G6 engines.

@gadeshi is RCS of Pak fa being quoted 0.1 to 1m^2 is for frontal or all aspect stealth cause f 22 marbel size RCS is from front only & according to latest report even f 35 frontal RCS is less than F 22 but it's over all RCS is more

We don't know it for sure (frontal is too simplified and secret), but PAK FA devs give it 0,1m.
As for F-22 0,000001 or the like rumors, it's secret as well. There is some F-22 dev team members interview in which they say that F-22 RCS is a big deception as they have applied 350kg extra RAM coating to make it pass RCS tests :)
It's obvious that F-22 could not fly with such an extra garbage on it :)

Wait for the T-50-6-2 and above models to come online I don’t know about the outcome of PAKFA RCS test UAC /Sukhoi bureau wanted to conduct recently may be @gadeshi can update us as for your “all aspect’’ Stealth someone rightly said before The final design of the PAKFA along with its full suite of RAM Russian TOP COAT equivalent, blockers, and even design changes along with clean sheet propulsion design (new engines) and new engine cowlings is yet to fly even as a prototype. The RCS measurements u quoted are of Patented design of initial phase..... I am happy for the guys at Sukhoi bureau now that Iran is also opting for Su-30s they may not feel the CASH CRUNCH because of declining OIL prices and Western sanctions.....

At the top of this, single aspect ratio cannot be described with single number. There only a numbers range can be found as a result of screwing complex differential equation resolution. Single digit is too simplified and serves more as advertisement.
And of course you cannot expose all-aspect RCS as a single number - it is physically impossible due to RCS diagram appearance.
But you can define ranges for each aspect by resolving a multi-dimensional matrix (system of differential equations described above) to buikd all aspects RCS diagram.

About RCS, the F-22/35's front-on RCS values are deceptive. They have effectively chosen the sector of the plane that has the least RCS and are marketing it as the radar signature of whole plane. Now it is true that F-22 has extremely low RCS levels even from the sides & rear, but it still does not remain as stealthy as the front-sector.

And the front is only one value. There is no guarantee that an enemy will always come from your absolute 12 o'clock, level. He could appear from the sides, from below or above. You only need to change the aspect angle by even as much as 1 degree, and the RCS changes, or should I say increases.

If a smart modern radar even gets to read the returns from a stealth plane from a couple of different swaths, there should be enough data to identity it as a contact. Ofcourse I admit these are highly relative scenarios and, as of the moment a binary answer (yes, or no) is difficult to give.

They stole the main wings plan to Lockeed ?

Very stupid meanings to be honest.
T-50 is more like YF-23 by Northrop-Grumman than F-22 from Lockheed.
The only common thing is normal AD scheme :)
Thanks for "Stupid".
No, look T50 from below. The wings, in quite all détails, is a F22 like.
