Honestly, I don't know but RBE2 XG will get multi fonction antenna and will have to collaborate with SPECTRA so the evolution seems to merge the two system in one, perhaps by steps, after a first step where they are separate...
Both J-10C and J-20 shifted to WS-10 sometime back. J-20 has now reportedly shifted to WS-15 engines which allow it to supercruise above Mach 1.5.
Majority of their fleet is running on al-31 variants. You have j-10A/B/BSH,j-11A/B and initial model D's. The j-16's run on al-31's too. Su-35 and su-30mkk's too which use al31 variants. The ws-10 is a marketing gimmick atleast for the next two years. Don't even forget the huge chunk of j-7 and j-8 variants that make 1/3 of their AF
The APG-85 is intended for batch 17 of the F-35 block 4 which would enter service in mid-2029, if all goes well, barely 6 months before the RBE2 XG.
There are only about 100 J7 and J8, which only account for 1/20 of the total number of Chinese fighters
With the exception of the early part of the J15, all Chinese flankers use WS10,Another part of the J10C also uses the AL31, but it uses the AL31FN Sep3 engine, which has 1 ton more thrust than India,The early J10A/S are gradually replaced by WS10B
WS10 was originally derived from the G9 core engine of the mapping and imitation CFM56 civil engine,The G9 core engine is used in the F110 engine.Of course, WS10 references some of the AL31's designs, such as the compressor and the casing
The french and Americans shared the cfm56 tech for commercial airplane engines the Chinese used that to "reverse" engineer them into mil turbofans. There's a thread on brf. It's an interesting story.
J-11's,su-30mkk's,su-35 and your early j-16's all use al-31 and it's variants. 2/3's of your j-10 fleet runs on al-31's.
Like it or not, Chinese have made a breakaway in jet engine tech. They are still decades behind US and Euros. But they have almost caught up with Russia and that says a lot. Most of their current fighters are now powered by their own engines like WS-10 and WS-15.
The J-11A is an assembled production of the SU27, naturally using the AL31, and the J11B uses the WS10A, which is an improved Chinese design
Scary sight for any opponent(including ourselves). That's why 4th gen/++ planes still have a place in modern air-combat. 10 missile load is nothing to scoff off, IMO.
