J-20 5th Gen Fighter Thread VIII

Generation-wise, I think WS-15 is on the same generation as F119 and F135, i.e. 4th.
But in terms of max thrust, WS-15 is somewhere in between F119 and F135 (more likely to be closer to F135).

In terms of thrust it is superior to F119 and on the same level as F135.
Or if they will have reduced vertical stabilizer when it will happen. Just enough to cover nozzles IR signature from the sides.
In terms of technology, I think it is better than F119 and F135. You need to understand that F135 got the higher thrust by increasing its bypass ratio compared to F119. For the same engine core, higher bypass ratio increase thrust at the cost of lowering the maximum speed of the plane. F135 and F119 has similar technological advancements. If anything, the WS15 has a even lower bypass ratio compared to the F119, yet it has a higher afterburner thrust. Like others here, I am still waxed by how the WS15 has slightly lower military thrust while having a significantly higher afterburner thrust compared to the F119. I guess we will get our answers down the road.
Don’t overestimate WS-15’s max thrust. Trade offs are made to optimize high speed, high altitude performance.
That's debatable. If it is only the inclusion of TVC, in the scope of all of the other changes from J-20 to J-20A, it could just be included under J-20A, especially if the production version of J-20A has TVC as standard.
Should 18.5 tons be a reasonable estimate for WS-15's max thrust? Cuz that's a pretty widely quoted figure right now.
