About next generation engines, there is one non VCE project with max ab thrust of around 200KN, TIT 2400K and 15% better fuel efficiency as the less ambitious option. There is also a VCE project with TIT close to 2600K(?)

That diagram showing a 2400K engine with 17.97% more thrust than f119, turns out it used a ridiculously high source of f119 thrust in itts references, so final thrust should be around 200KN

Yup, the Cooled Cooling Air proposal:

Yes, I think this is more likely. Though it maybe possible for a two stage LPT considering this engine has to have enough shaft output potential to drive the lift fan.
IIRC the F135 also is 3-6-1-2 for the exact same reason you said.

So this engine is possibly planned for cca integration in the future, a cca with 2600km range is indeed the way to go for battles in the pacific. VCE is perhaps too expensive for use in CCA i guess.

Just in case - the CCA here stands for Cooled Cooling Air, not Combat Collaborative Aircraft (although it is entirely possible for a drone to use it too).

Ah I see, that explains a lot. So for the J36 a non VCE version will likely have a combat radius of 2600km, the vce version might quite possibly reach 2600*1.3=3380km. Better than expectations I would say. A high end drone will most likely be using a single new engine and a more attritable cca could use a single ws19 or ws21. Anything even smaller then no real radar system and effective range.

Theres nothing to indicate this engine is actively being developed

in last ten years AECC revenue exploded so they started many programs, investing tons of money in R&D. and it is not necessary that, all research will translate into a physical prototype or just say enter in service. this 2400K TIT is actually exist. this maybe for next gen Engine like ACE/VCE.. remember that chart from Nanjing University.

China also did invest a lot in material science and continue to invest.

Given how MIC speculation goes there's also nothing that says this engine isn't, nevermind the underlying concept getting further fleshed out by the major engine institutes.
IMO there is little application for further conventional low BPR turbofans however this cooled cooling air concept could prove to be useful when combined with VCE designs to achieve ultra high TIT.
