How come there are no good clear images of a Y-20B yet? Or have I completely missed them?
well, it is not yet in service
A pair of J-20 were spotted refueling from a YY-20B. I think they’ve been in service for some time.
Yes that is supposed to be WS-20 but since this image is an artist illustration/CG, the real WS-20 engine housing may looked different as illustrated.
