Not sure what you're speculating about.

Me too !?? :eek: ::)

IMO the one on top is difficult to use (does it have the same scale ??), since it seems only to have scaled the nozzle diameters to the same size.

On the other side that's not a real problem since - even if we still don't have clear shots of the AB-arrangement like flameholder and so on - I'm convinced that CAC once again turned to Saturn to use an AL-31FN vesion.

That's the idea!
We assume that both aircrafts have Russian engines such as Al-31.
The J-20 truly has a great size.

Bad choice of pictures lead to bad assumptions. Are the exhausts both open to the same angle?


We've been over this before, I see nothing interesting or useful in your pictures to add to the previous calculations done.

Hold on now, that second picture is great.
It shows 2002, the second prototype. Which means you can now claim that there are two flying J-20s and actually be credible when you do so.

Sean was alluding to the overheated "two prototypes" discussions when the first prototype was unveiled.

Whenever I see J-20 videos I can't help but wonder if the residents know what a blue sky looks like.

Part of it has something to do with air pollution but the climate in Chengdu is mostly responsible for the foggy weather.

Obviously you've never lived in Seattle, it all looks perfectly normal to me! :)

I still can't quite mentally reconcile China, land of the execution van and forced labour with China, where you can film this sort of thing and stick it on YouTube.


And what's with the flexible tail? :eek:

You can film it because China wants it to be filmed as proof of how powerful they are becoming. Its not like they couldn't have been doing all of this at an isolated base had they wished.

And get him a decent camera. I'm tired of the Keystone Cops jerky framerate.

Looks all right. Reveals some lines and rivets. A bit more of quality shots and we'll probably get some good panel shapes

It looks no difference from 2001.
Sorry if my comment was misleading and You are correct that besides that new pitot and the ability to close the MLG dors while taxying the only "new" observation is this yellowthink with these <> corners.

Otherwise I think this shape is interesting ... but again not new !

Hey, correct me if I'm wrong, but in the final few seconds of the video posted by Deino ( many thanks) you can see the backs of as many as FOUR J-20s lined up :eek: !

It is quite possible that this part already exists on #2001 but was painted black from the outset and therefore not as visible.

That notch in the nose mold line is probably where the forward-looking MAWS sensor is located, IMHO.

You can't exclude it, but when the first photos of the J-20 surfaced, many, including me, suspected PS might've been employed. Please note it hasn't been settled unequivocally yet whether a/c no. 2001 had two differrent engine types fitted, or there were/are two different examples bearing the same bort number. If the latter is true, we already have at least three examples. And how long was it before Chinese authorities officially admitted the existence of the J-20 after the type's photos flooded the net? When it comes to military technology, the official story is usually far behind the current state of affairs.

Bit off topic here, but relevant.

I was going through an old flash drive of mine when I came across this picture:


Last time I used this flash drive was several years ago before the J-20 was revealed, but it matches almost perfectly the center plane. The upper plane is that new Trainer the Chinese have, but I'm more interested in the lower one, which seems to line up well with that plane we've seen pictures of on the highways. Could this image have been a leak years ago from maybe a Chinese PowerPoint showcasing the future PLAAF airfleet? Just seems too creepy with how things have lined up so far.

I doubt it. The j-20's shape has been circulating around the web under the term j-xx years before the unveiling.
