I understand and that makes sense, but does that we mean they are down to 1 J-20 dadui at Cangzhou and that there are more than 3 J-20 daduis at Wuhu?
I think Cangzhou always had only one dadui equipped with AL-31FN-powered J-20s with 7823x numbers (if it ever was a full dadui?) and again one dadui equipped with WS-10C-powered J-20As with 7803x numbers (again if it ever was/is a full dadui?)
so we are saying 7823x is no longer there. There is only 7803x. So basically just 4 AL-31FN J-20 daduis in total. 3 at Wuhu + the original one at Dingxin. Rough guesstimates. About 40 J-20s with AL-31FNs (let's call that batch 1). At least 56 J-20s with WS-10C (batch 2). Sounds pretty reasonable?
This sounds about right.
If we extrapolate further. They had close to 3 daduis with WS-10C after their mid year delivery in 2021. So that implies they produced 25 to 30 J-20s in the second half of last year. We know from past years they normally do 60% of their annual deliveries in the second half. Therefore, they likely already hit something close to rate of 50 a year by second half of 2022. That's quite impressive.
Yeah I think when we collate all the details with deliveries and serials it’s starting to sound quite likely that CAC did indeed expand J-20 production to 4 lines, which makes 50 a year quite likely as the current production rate. Would be curious to see if this is where the production rate stays at or if it expands even more into the future.
Continuing the discussion from the PLAAF news thread here, I wanted to compare the backsides of the J-20 and F-35
I don't believe the F-22's rear is relevant here since it follows different principles. Also, I remember reading some USAF general claiming that the RCS of the F-35 is superior to the F-22. Given that it's a more advanced aircraft designed with a more experienced industrial base, I have no reason to doubt his claim.
Giving them a look over with a Type 01 eyeball, it certainly seems like the design of the F-35 is more elaborate. The serrations are finer and they seem to have some treatment around them (like the some J-20s have on their missile bays). Also, the nozzles themselves have some complementary serrations and the engine sits deeper in the housing.
By contrast, frankly, the WS-10C looks like it could use some work. It definitely screams "interim engine". I also would like to understand the rationale behind the different choices of serration size, as I'm certain CAC could make the serrations smaller if it wanted to (there are smaller serrations on other surfaces of the J-20).

@tphuang @latenlazy Could we continue the J-20 discussion here?
