Two interested shots of an F-22 and an F-35B, both naked, for a rough comparison in synthetic parts coatings:

YF-22 vs F-22 changes were considerable but what we’re talking about here for the T-50 is something very deep. Look at this underside picture of the aircraft:
The engine nacelles are almost identical to Su-27 and I can bet there’s some very wide frontal angles where the engine face can be seen. To hide those, they’d have to get rid of the rear weapons bay and make it look more like the S-37. If they do that…thats a whole new aircraft. In fact I’m surprised why they didn’t build on top of the S-37 instead of the Flanker.
Its clearly focused on frontal RCS reduction, but right now given the alignments of the engines and the rest of the fuselage, that will be nowhere near F-22 ranges (or F-35). Side and rear seem to be getting little attention here.
I’m going to go out on a limb here but this seems like a dressed-up Flanker rushed into prototype stage in order to attract the Indian’s attention. Expect another 10 years of improvements on this.
Nice pic, thanks for sharing. The first shot I see from beneath, very interesting.
I could agree with most things you say, for they are far from irrational. The problem is, your way thinking is too “american”, so to speak. Don’t get me wrong, I don’t mean any offence.
It reminds me of a comment I read at F-16.net, where there was this guy who (typically) argued that that the PAK-FA was nothing but a copy of the F-22, and at the same time he argued that… well, it is not enough like the F-22, so it’s not stealth enough. It’s as if the world of stealth in aeronautics begins and ends with the F-22.
Hillarious.
F-22 = Metal Marble
F-35 = Golfball
PAK-FA = ?
That’s the million dollar question I guess. But then again, it would be better stated as Su-4x RCS = ?
Cause right now it’s as if you are asking the YF-22’s RCS. Who cares about it?
In the heart of the question, only speculation can be made, nobody can either claim or reject any figures.
Sure…if they change the engine positions, the engine intakes, and change about half the alignments on the aircraft…Then it would be too early to tell 😉
Oh, roughly the same (and more) things the Americans did to the YF-22. You are so right, got to agree with you on that.
But looking at straight curved engine nacelles with large intakes which don’t leave much room for any s-ducts, some very unaligned angles throughout the fuselage etc. It can be improved as its surfaces are refined in the future…but its very configuration means its not going to be near F-22 levels of stealth.
O rly? According to whom? It’s a prototype we’re talking about… It’s like saying that the original T-10 is so crappy and not even near to the manuevrability of the F-15. If you had made that statement in the seventies, you would possibly sound right. But today you would sound funny… :rolleyes:
It may be all dressed up…but I’m not convinced. Clearly a huge step forward fro the Russian aviation industry, but certainly not near F-22 or F-23 stealth capabilities.
It’s way too early to tell. :rolleyes:
Considering it took the USSR about double that time to get Su-27s into front line service since the first flight of the prototype…I really doubt Russia will do it twice as fast 😉 This plane will enter joint development with India…and you can be sure it will be in Indian service before Russian.
According to Novosti, contract was awarded on Aprin 2002, so first flight was 8 years later. By comparison, contract for the YF-22 was awarded on October 1986 and first flight on September 1990, four years after. But it was introduced in service in 2005, roughly 20 years later, and still it is not regarded as completed or fully to the desired standards.
Will the Russians do better? Nobody knows, nobody can tell, only speculate. If they do just as well, they would introduce it to service by say 2020-2022, twenty years later, just like the Americans. I think they are capable of at least that.
yes he did, that guy is me 😀
i used a 1/144 F-23 as a basis, i never thought it could actually near the real thing. i am planning one in 1/72on topic:
i think it does look like the YF-23 (from the front anyway) 😀
Well, it’s a small world, isn’t it. 😀

aditya The F-35 looks more like a baby T-50 than a baby F-22 as some folks found it5,500 K range seems too much
That would depend on the engine, wouldn’t it. 😉
I think many of us including myself are guilty of responding to potential flame biting in the IAF thread. Let us make a pledge to ignore all off topic posts by the usual suspects.
(no offence whatsoever) Off topic situations do not arise because someone posted something off-topic; that’s daily routine. They arise because someone else replies to that.
Best regards 😮
The PAK-FA that flew yesterday is still more like a techonological demonstrator: Engines from the flanker, no radar, no electronics for productional fighter, and no EWS.
I wouldn’t be surprise if a real protype of early productional PAK-FA (with radar, basic electronics & EWS and so on……) comes out at the time of 2013.
The engines were not from the Flanker, so says NPO Saturn, unless if you have a better source…?
Hej, look at that! This guy actually almost made it!!!

Since we are free to speculate for the time being, do you think a 2d IR-hiding nozzle will be incorported in the long run??
Hej guys! Putin says will be in service by 2013! I’m sh*ting you not!
Russia to start receiving fifth-generation fighters in 2013
29/01/201016:42 The first batch of Russian fifth-generation fighters will go into service in 2013, Prime Minister Vladimir Putin said on Friday.

Thanx for sharing Otaku. Very nice sequence, with no TV stations’ watermarks too. 🙂
Pardon my ignorance, but, are those ‘All Moving’ tail fins?
Yes. Watch closely at 0:43-47
P.S. Can see the “VS” threads working over time now…Especially on f-16.net…And they don’t seem to approve “non American” types over there…Should be interesting if a little sad.
Yes, I noticed it too. Nobody enjoys competition/loosing his monopoly. Arrogance is at serious surplus over there. I couldn’t imagine what would happen when the PAK-FA would actually become operational… Some people might actually turn to alcohol/drugs :diablo:
How realistic do you think this weapons load is? As far as I can tell from the pics, only 2 pairs adders in tandem would fit, but I don’t know. The drawing is otherwise accurate though.

Which brings me to the second question, obviously these guys had some sort of hints, they didn’t made these drawings by chance, did they. Nor did Sukhoi saw the drawings and tought they’re cool, so let’s make the PAK-FA like them. Obviously it was a well controlled leak…
What about the tail cone, do you think it will incorporate a mini backwards looking radar? Has enough space for that, it seems…
