A side by side pic showing the physical difference between J-20 (I and II) and J-20A (WS-15) would be nice.

And the twin seater is J-20B not J-20S regardless of the of the engine? Well I'm guessing they will be taking the WS-15 if they haven't enter into production yet.

yeah.....?
The Soloviev D-30 (now the Aviadvigatel PS-30) is a Soviet two-shaft low-bypass

...do you realize that every single turbofan engine (F119, WS-10, CFM-56) by defination can by refer as a bypass turbojet?

2. Later batch J-20 is a completely different beast from their earlier brethern. Despite the fact that the early batch has received software updates, after mock combat engagement with the new variant, pilots of older J-20 lament that their aircraft is a bit of a technological laggard.
I previously asked a question of whether we'd heard anything on the J-20A systems being retrofittable on J-20s. Would it be fair to say that Yankee's article implies that the J-20A shares some of the J-20B's new internal structures and processes, thus making it unlikely that J-20 airframes can be brought up to the J-20A variant without difficulty?

Excellent article by Yankee regarding the WS-15 flight that leaked a lot of interesting tidbits:
1. There are a lot of system redundancies on the J-20 to ensure that even if the plane has been damaged by enemy fire, it will retain limited ability to fly and fight. This makes maintenance of the earliest batch of J-20 very difficult. Later batches have significantly improved on this.
2. Later batch J-20 is a completely different beast from their earlier brethern. Despite the fact that the early batch has received software updates, after mock combat engagement with the new variant, pilots of older J-20 lament that their aircraft is a bit of a technological laggard.
3. J-20B (the twinseater) already incorporates most of the technologies used on J-20A, despite not having the target engine.
4. WS-15 will not only improve maneuverability and supersonic performance but also provide additional redundancies for onboard electronics, cooling system, and hydraulics.
5. Y-20 news -- one of Yankee's friends had the fortune of participating in a test mission on a Y-20 with WS-20 engines and claimed that he was able to get some good sleep onboard. Does this mean that the engine is a lot quieter?
Any comments on improved stealth the new airframe would offer?

Older J-20 probably can’t retrofit the same stuff that goes into J-20A but they’ve had at least two internal upgrades. See Yankee’s comments about differences between early AL-31 J-20 and WS-10C J-20.

Thanks! My interest in this stems from trying to understand what happens to the early J-20s. Going off Scramble, I think the PLAAF sent several J-11 brigades the J-16 as replacements, so would it be fair to say that the brigades that currently have J-20s will probably get the J-20As and have their J-20s sent to other brigades?
