J-XY/J-35 carrier-borne fighter thread

- Start date
A J-35 spotted conducting test flight. Location and time unknown.
Addition:
This is a video from the historical archive. Not new.
I've came across some figures regarding the J-35 and quite frankly, I don't know if I should take them seriously.
Apparently, with the research of Wang Xiangming, they managed to control the empty weight of the J-35 to a ridiculously light figure. There are images floating around of the new, revised structural design in a paper. Called 《飞机新概念结构设计与工程应用》, which translates to "New concept of aircraft structural design and engineering applications".
The figures floating around ranges from 16-14 tonnes (which is already quite unbelievable), and a few claiming 12.5 tonnes (AL-51 having 200+ kN thrust level delusion imo, but we'll see).
The figure I heard the most is 14.5 tonnes. With WS-19 rumored with having around 112.5 kN of thrust each and a pair's combined weight being *less* than a F135, that makes approx. 225 kN per aircraft.
That means a whooping thrust to weight ratio (empty) of 1.582. Taking fuel, payload, even 2D TVC into consideration, it'd still be around 1.3 to even 1.5. The J-35 would have the highest t/w figure in terms of fighter aircraft, in the entire world, right now.
I'm taking this figure with an entire salt mine. Even if I increased the empty weight to 17 tonnes and a combined thrust of 210 kN, the t/w would still be 1.26.
Onto the most ridiculous rumor, 12.5 tonnes empty and 235 kN combined, the t/w would be 1.9. Which, quite frankly, have an *extremely slim* probability to straight-up impossible.
My *very* optimistic guess would be 1.45. The realistic, safe figure would probably be 1.3, or even lower. But still, in an optimistic scenario of the J-35 having 2D TVC, it has the potential of being the most versatile (and perhaps even agile) and stealthiest 5th generation fighter. Hence I'm quite doubtful of these figures. Take em with a whole mine of salt.
Does anyone know any solid info about the J-35's weight?
Here's some pictures from the said paper:

Additive/3D manufacturing of fuselage parts and use of advanced composites might reduce weight considerably over a conventional design.
Judging from the graphics provided the paper is talking about FC-31 (no folding mechanism for the wings and flaperons instead of separated flaps and ailerons) so while FC-31 and J-35 no doubt shares the same lineages and similar levels of materials & manufacturing tech, I’d take a pinch of salt when applying things discussed in this paper on the J-35.
additionally from memory the 12.5t empty weight initially was referring to fc-31 ver 1.0, even if this claim is true the J-35 would most likely be quite a bit heavier
The paper is really just a proof of concept.
And yeah, hence my guess that the J-35 would be around 14.5 tonnes.
F-22 @ 19t empty weight and 31,8 tons of thrust comes in at 1.67 twr...
What does the Su-57 engine got to do with this? And why start with a higher number than the lower? It's confusing.
