And so we have three J-20s already with the Milka-scheme.

Wait a minutes. It is 2021. If my memory serve right, there were another 2021 some time ago. This is the same aircraft, or a different one. @Deino, can you give a confirmation about this?

The 2021 is the aircraft seen a couple months ago with WS-10X engines ... there are currently two prototypes with Taihang engines ... the 2021 and the yet to be photographed 2022

HAPPY NEW YEAR
GOOD LUCK IN DOG YEAR

According a fyjs insider, without lens, the ground radar station will lost the track of J-20 (without stealth coating) in a matter of mins after J-20 take off.

Thats why you see lens are always attached to J-20, even in its factory un-coating status.

So basically you're saying the J-20 is ridiculously stealthy even without its RAM coating that the luneberg lens has to be mounted on it at all times or GC will lose track of it very quickly? That's pretty amazing.

That's an incredible shot. Always wondered why the canards are dihedral.

磁爷 is an unreliable source. He may know something, but he always create some extra "detail" to them.

Actually such performance is expected to a true VLO design:

The coating can at most reduce the RCS by 10dB or so, the shape should contribute the majority work of RCS reduction, and fighter can travel about 30km in mins since take-off, in other words, ground radar lost tracks in a matter of mins for J-20 without coating basically means: J-20 with coating should reduce a ground radar station's range of detection to <20km, which is expected for a VLO design.

The australian Klopp or someone did a rough RCS simulation about J-20 at the time J-20 first revealed, and he believe the RCS of J-20 is pretty good, the front RCS of J-20 is in the range of ~-40db according to his simulation, which is well qualified to be a VLO design.

磁爷 is an unreliable source. He may know something, but he always create some extra "detail" to them.

He just hate 601/SAC and love to mock them, but many of his informations are reliable as time proven, much more so than some sources in CJDBY like ridiculus rumors such as PLAN picked FC-31/PLAAF love FC-31/thousands of FC-31 are ordered by PLA or Yang Wei become irrelvant etc.

Many open news sidely proved his stories.

That "extra detail" can destroy his credit.

You have too high a standard for internet rumors and insiders, if such standard were applied, I guess you should stick to CCTV or other official channel who may take years after photo/video are all over the internet to even acknowldege the existence of something.

Generally speaking I found his stories are usually reliable, of cause he has some personal "bias" against SAC, but it is pretty easy to spot and you can screen these out if you want.

There are many relative reliable rumor source on internet like huahua，pb, 猫版, 席亚洲 and 星海.
