Guys ... maybe a strange question esp. since I'm most of all interested in NEWS, fancy images and serial numbers but most recently - probably due to the fact that since 1. October nothing new was heard on the J-20 - here in this thread and in other too (aka the FC-31) there are pages of endless discussions on weight, manufacturing techniques and estimations ... not really directly related to both these fighters.

So my question ... should I leave it as it is or shall we move these part out into a new dedicated thread for discussing such technical issues?

What do You think?
Deino


By the way ... this is a J-20A ... for those who already don't know how it looks like :)

Come on guys lay it off enough of this never ending discussion nobody is going to convince the other guy. This forum is not for people who want to show who has the bigger d(*&%
Here is some news. It make sense that they deploy the first operational regiment close to hot spot

China’s stealth jet may have done flyover of S Korea
A vaguely worded statement from the PLAAF has made some wonder if a J-20 fighter was deployed to gather intel on a US-South Korean war game

Has China’s fifth-generation fighter the J-20 just accomplished a top-secret reconnaissance of the ongoing war game Vigilant Ace between the United States and South Korea, totally undetected by either military?

According to Chinese news portal Sina, yes. Evidence?

The People’s Liberation Army Air Force (PLAAF) said on its Weibo account on Monday that its reconnaissance aircraft, during a scheduled training exercise, took off from an airbase in northern China and flew routes they had not taken before, “to places they had never been before.”

Some military observers in China believe these planes traversed South Korean airspace above the East China Sea and the Yellow Sea. Yet what is interesting is the fact that Seoul has been silent so far.

Some speculate that Korean radar must have failed to track Chinese reconnaissance planes tasked to gather intelligence on the joint drill, for which Pentagon has marshaled its ace warplanes including F-22s to the Korean Peninsula.

“If that’s the case, then the only Chinese plane that was so stealthy that [it] could come and go totally undetected must be the J-20,” one commentator said.

“One or two J-20s may have flown with the group, which first headed to the East China Sea in a freedom-of-navigation patrol, but the fighter then turned northeast and pierced Seoul’s airspace, taking advantage of its cutting-edge stealth coating without triggering any alarm on Seoul’s radars.”

Other sources suggest that the PLAAF has started deploying a small batch of J-20s, which just entered service this year, at its key airbase in Cangzhou, in the northern province of Hebei.

Cangzhou borders the Bohai Sea across Korea Bay as well as the west coast of the Korean Peninsula, but is secure enough as it’s guarded by China’s Shandong and Liaodong peninsulas.

All this speculation is from that one statement that J-20 had gone where they had never flown before?? LOL

Now from what I think I understand, J-20 might very well get there without being seen but coming back is a lil' trickier since those engines were not made for rear-aspect stealth... In any case, if their only source of speculation is that incredibly vague statement, then I'm not convinced at all. After all, doing something like this is very risky with minimal benefit. Then, if successful, dropping hints that it happened to alert others is just... not the personality of the CCP in my opinion.

The reporter is a moron. It was the TU-154 reconnaissance

J20 is not an all aspect stealth because it was not designed to be. It just has enough stealth to make it effective at A2A engagement mostly at stand off distances.

If it had overflown SK on some sort of recon run, I'm 100% sure SK's air defence umbrella would've seen it.

so yes you're right, reporter is a moron but unfortunately this is quite common when you have non-technically adept people report on military or more technical matters.

Is that a fact? If so, there ought to be mass firings at Chengdu if they thought it was acceptable to sink billions into a project they knew would result in a crippled fighter. Happily for the employees at Chengdu, they thought no such thing.

The current iteration of the J-20 might have some problems with radar returns from the rear because the engines haven't been shaped and treated for RCS reduction. This is a problem that is being partially addressed by the WS-10 variant being tested, and will be fully addressed by the WS-15.

The J-20 was designed to be, and shall be, an all-aspect air-superiority fighter.

Let's not be so harsh, we all make mistakes.

Your own statement agrees with my observation... the J20 is certainly NOT an all aspect stealth at this point in time which is what the subject is about in regards to the article.
The bolded quote above I agree with. This I don't:
J20 is not an all aspect stealth because it was not designed to be.
Besides, "detecting" and "engaging" a stealth fighter are two very different propositions, as I'm sure you know. China's long-wave radars regularly pick up F-22's and F-35's -- so let's leave aside the snark about "getting lucky" over Myanmar or Sudan.
