You are all forgetting one big advantage of transport-based turboprops - austere/remote basing. Props can use much shorter runways than jets.
I don't think that's an advantage inherent BECAUSE of turboprops. Aerodynamics and the wing design play a far larger role than engine choice. IIRC the C-17 has a better STOL capability than the far smaller and turboprop Y-9. The only advantage turboprops have in austere basing is less risk of FOD.

So, where is the engine for this 120-200 tons platform. The only thing available right now is 120-140kn WS20 spinoffs,
which means it has to be a 4-engine platform, or a sub-100 tons dual engine platform.

two WS-20 upgraded variants are more than enough to power 100+ tons mid size utility aircraft.

what i have heard, they are planning for mid sized twin engine platform for ASW and other purpose. the purpose of twin engine platform is cost and easy to maintain.

Having four WS-20 engines on an aircraft would mean an airframe with MTOW of about 200 tons, i.e. about the DC-10's and 767's category. At this stage, you might as well go bigger with a military platform counterpart to the 787, A330neo or C929 straight away.

Moreover, given that the (base variant of the) WS-20 has a max (probable) thrust range reaching 160kN, it should be viable to uprate the engine into having ~180/190+kN of max thrust. Otherwise, with allegations/claims of a ~250kN max thrust engine being currently under development (likely for a Chinese counterpart to the C-5 and An-124), such engines can certainly have a downrated variant of ~190/200+kN of max thrust.

I wonder if the CJ-2000 350kN class engine could be used for a mega-sized transport aircraft like an AN-225. 4 of those could give you over 1400kN of thrust, that should be enough. Though I doubt China needs or wants such a humongous plane.

pretty good clip and stuff coming out on KJ500A here

says it can search out stealth aircraft from long range out. Can direct electronic warfare aircraft to attack the other side. Forms a kill chain with J-20. And has been used in exercise to assist 4th gen against 5th gen (not a surpise really). Says it has electronic reconnaissance and spectrum sensing capabilities.

I'm assuming that last part is about the ability to passively connect electronic emissions from across the spectrum. It would always make sense for ESM to be a huge part of this aircraft and for it to gather it from front and side antennas.

here is the part about KJ-500A improvement over KJ-500. Specifically mentioned the improvement in radar, allowing for deep searches against stealth target.

here is a much longer video
