Any image of two WS-15 engine prototype?Sorry in case I misunderstood your post And yes, so far J-20A no. 2051 is still powered by two WS-10C, the second prototype no. 2052 has indeed two WS-15 installed and concerning LRIP, that‘s for the engines, but not for the J-20A.
Recently, some declassified news has been circulating in Chinese social media.
After CAC won the PLAAF 5th Generation Fighter Bid, there was a shortage of manpower due to very limited mission time.SAC provided assistance.The main frame beam of J20 was designed and manufactured by SAC.
Allegedly the twin-seater was seen again …
The question therefore is, how recent this imagery is? My point is, both 2031 & 2032 are already grey, 2033 is known from an unconfirmed image … so either a new image of 2033 or even a new prototype

Supposedly this was one of the designs which lost to Chengdu J-20.
IMO not too different from J-20.
Canards, a bit elevated above wings. Tail design more «traditional» though.
