WTF? So basically they are saying this plane is different from other 5th gen, but still a rip off?

Who the hell said that the plane was similary to the Saab Viggen? So much for "Experts" these days. I think I should end my engineering career and work as one of those "experts" instead.

It seems many of these military journalists visit Key Publishing Forum. There was a upset poster trying to say the J-20 was a rip-off of the Typhoon. Then when the first flight pics came out he claimed it was a rip-off of the Viggen. I bet that's what these journalists are reading as experts.

I can't believe that so many of you are complaining that your competitors are not pleased for you and congratulating you on your success.

In the real world the measure of success is indeed the sourness of the grapes that your competitors send you.


Long time ago i read this little phrase in a modelling magazine, that stuck in my head ever since . It basically goes ( please excuse my translation , english is not my native language):
"Nothing is harder to forgive than other people's merits."
Says it all isn't it.

Don't think i added my congratulation for J-20's first flight on this forum, so here goes, excellent job China! :D

Quess no matter what the J-20 looks like someone will claim that it is a clone, but of cause they also claim it is a better clone :)

Let recount what the J-20 have allegedly cloned.

Lockheed Martin F-22
Lockheed Martin F-35
Sukhoi T-50
Mitsubishi ATD-X Shinshin
Korean KFX-201
Eurofighter Typhoon
Saab Viggen

If this is true then the J-20 would have the best features of all the above fighters intergrated :) ROFL

IMO how successful your stealth plane is, dependent on the complete package. If the other guy has a superior weapons suite and radar etc etc , which allows him to see you before you see him then youre toast. Nothing can be more demoralising then seeing your fellow pilots being downed, and you don't know where its coming from.

as a example heres what one guy over at WAB opinionated?. Note Im not saying he's correct, because i haven't a clue on judging whether he's on solid ground when it comes to crunching the numbers.

"..... So, the J-20 should have a 50% larger AESA than the F-22, which, if the Chinese can get their AESA technology right, should increase SnR in DB by 50%, or reduce the F-22's effective RCS by 1.8 DB. If it's in the F-35 RCS range, then that reduces the DBSM difference from 10 to 8.2, which reduces the F-22's detection range advantage to 170/70%; the F-22 can spot the J-20 at 170% the distance the J-20 would. So, this works out to something around the J-20 getting detected at 22 nm and the F-22 getting spotted at 13 nm. The J-20 would get detected by the F-35 at 16.5 nm and detect the F-35 at 19 nm..........."

Please use your common sense. The performance specifications for the F-22, F-35, and J-20 prototype(s) are highly-classified military secrets.

For example, what's the RCS of the J-20? Firstly, it depends on which angle of observation that you're referring to. Secondly, no one outside of the Chinese military knows that answer with certainty. How can you answer the question if you don't know the effectiveness of the RAM coating?

Analyzing an engagement with performance numbers that are pulled out of thin air is a waste of time. As they say in the computer industry, "garbage in...garbage out." A conclusion based on imaginary stealth and radar specifications for the F-22, F-35, and J-20 is pointless.

Some of you fellows have no clue what this forum is about. It's about intelligently discussing Chinese military matters. Not bashing fellow members, the press/media or other nations because they make comments real or not about a piece of military hardware. China's a World Power..China shall be challenged at every level. Everything she does will be scrutinized. Get over it. That's how the World works.

In this thread all the above has occurred. SampanViking has already made a plea to change the level of you discussion. Apparently some of you have ignored him. Well now it's time to clean up this thread.

First off all of you need to read the forum rules...and obey them.

FORUM RULES: Things to Remember Before Posting, important, please read!

This thread is LOCKED for about one hour while I clean it up. If you post is missing when I re-open this thread so be it. Don't post the same garbage again.

DO NOT COMMENT ON THIS POST!!!

Hellooooo ...Thread open.

THIS THREAD IS ABOUT THE J-20 AND NOTHING ELSE!!!!!

1) Knock off the off topic chit chat.. such as US treasury bonds or debt..or the Olympics. ETC..ETC,,
2) Knock off the country bashing remarks.
3) Knock off the personal attacks.
4) Stop bashing the media.. they know nothing about the military. NOTHING! If they don't like China so be it. Trust me they hate the US also! You don't see me crying about it! Get over yourselves. China is in the big leauges now!! The hits and media scrutiny will just keep coming.
5) Knock off the silliness. This is not a internet amusement park.

Lastly >>>> Once again, this thread is about the J-20 and nothing else. Use the private message for personal chit-chat. Use the proper thread or start one for discussions of other matters.

.

Exactly, so tell me what puts you in a better position to dismiss out of hand, claims by Lockheed Martin that a breakthrough in stealth detection had been made. I think you are just like those who dismissed Chinese Claims of a 5th gen plane being around the corner.
Lets not forget the the Stealth is a the sum of many parts, and is as good as its weakest link. Or the fact that many people on this forum acknowledge that China is still a little bit behind in the tech stakes when it comes to constructing and outfitting the said plane.

Are you saying that it was LM that made the claim? Besides not even LM could make such claims about specific RCS and AESA detection ranges down to the exact mile of some unknown aircraft. And please refrain from making false accusations.

I think it is pretty clear that there are two J-20 prototypes out there, each one using different engines so the PLAAF can see which performs better. For example

j20-eng01-01.jpg

j20-eng02-01.jpg


and a couple of more showing the same:

j20-eng01-02.jpg

j20-eng02-02.jpg


Could those engines in fact be the AL-31F also used on the J-11 and the WS-10A used on the J-11B?
