Take a look at F-15 SE's background.... and then take a look at the PakFa..many similarities from an engine and airframe's standpoint. Both have 5th gen electronics and tweaked sonic cruise capability. But....both are STILL based on 4.5 gen foundation, i.e. the airframes.
Both Raptor (operational) and J-20 (even still in design) represent a leap over F-15 SE or the PakFa. If you don't want to admit reality, its up to you. If the F-15 SE was that potent to compare with the F-22, trust me, you'd be seeing hundreds of orders already inked. Similarly, if the PakFa was really as true stealth and advanced as other major competition, you'd have seen about a dozen Russian allies putting advanced purchase orders on it. But nope. That's not the case. As far as the J-20 is concerned, the engine issue is a whole different discussion but doesn't jeopardize its operational capability if they keep using AL-31 engines. Engine has nothing to do with its stealth or advanced technology related characteristics, as long as the engine can provide the thrust the jet requires. J-20 is based on the Western tech as its known, stolen tech at that. But PakFa is a traditional Russian design with stealthy features.
Based on 4.5th airframes... were you part of Sukhoi's DFMEA to claim that... visual cues are not the basis to analyse any design....
So I ticked you guys off because PakFa would become an Indian plane and only God knows, the Indian people or their products can't have anything missing and they are better than everything else? Common guys, when does the blind patriotism become common sense? Wish to see sense taking over important discussions.
Read my post three times and then read your responses. I think you sound like a smart guy, you'll see disproportional responses to a credible fact based discussion.
I never said J-20 is on par with the Raptor. Let's make sure we are on the same page. There is NOTHING on par with the Raptor at this time in the entire world or all the way till 2025. J-20, however will be second to the Raptor and the JSF (although J-20 is STILL inferior to the Raptor).
Now when I say SECOND to the Raptor and the JSF, that's coming from analyzing other Stealth projects around the world. The J-20 is based on very modern Western stolen tech. Like the F-22 and the JSF, it is ALSO based on a brand new airframe with many sensitive techs and capabilities. Russians are smart people, no doubt about it. But they also produce planes with certain things in mind, the use of nano-tech is barely there in their Jet manufacturing. If you just take a look at their top line jet cockpits just 5-7 years ago vs. a Western top line jet's cockpit from 10 years ago, you'll understand what I am saying here.
So I am more than positive that the PakFa is a very potent plane and it'll probably have super low RCS, enough to consider it "Stealthy", but its SU based airframes come with their own issues by design and you couldn't make a "Stealth" plane out of that.
Remember, Stealth and Stealthy are two VERY different things. So back to what I was saying, the Raptor and the JSF will rule the skies around the world. The J-20 will be the second thing to them and then the PakFa, and then the Japanese or Korean stealthy planes.
Air frame analysis on Appearance, Stealth validity on skin profile, Engine analysis on perceived manufacturing capabilities... Quick question what does ruling the sky means?
