All I'm going to say about this discussion is "guys, we don't have numbers".

Here's an article with some authoritative takes on the J-20's weakness.

The author Alex Lockie has a degree in "Rhetoric and Composition/Writing Studies"... Could someone educate me on what this is precisely and how it relates to material science, applied mathematics, applied physics, and aerospace engineering?

As many have mentioned, a TVC is very heavy and will change the center of gravity of the plane. So my understanding is that adding a TVC to the J-20 would literally mean that they will need to redesign the entire plane.

The J20 was designed with WS15 as intended engines, and the WS15 is almost certainly going to be heavier than the AL31s currently used.

As such, the J20 design would have already have allowances built in for the heavier engines, and are probably using ballast to maintain COG position with the interim AL31s.

The big question is whether the WS15 is designed to have TVC. If it was, the extra weight should have been accounted for in the design, in which case once the WS15 is ready, you just remove the ballast and COG is maintained. If not, then yes, it will be hard to integrate them later.

IIRC, TVC is not a mature Chinese technology; the J-20 would benefit from, but is not designed to require, TVC.

... A new J-20A at CAC or one of the older ones with a new MLG-door ?

... A new J-20A at CAC or one of the older ones with a new MLG-door ?

Probably a new one that hasn't been fully painted yet.

Also, why is it called J-20A and not J-20?

So now we have 5 types of paintjobs?
200X Black
201X Silver with red roundels
LRIP Silver with low vis roundels
A single one with Silver with Russian style splinter camo
And now this F-22 ish paintjob?

Are they experimenting with this?
