Now that we are finally getting to mass production of Y-20B with WS-20 engine (reported going into service next year), I wonder if this is when production for transport and refueling variants really take off.  I remember listening to an interview from Zhuhai 2018, where the person being interviewed by Shilao crew said that they need 10x the number of IL-76 order that they put through in 2005.  That would put requirement at 300 to 400.  Clearly, that hasn't happened yet.  So, I feel like Y-20 production is a little bit like J-20.  The initial batch in Russian engines is suboptimal.  As such, they didn't produce it at as high of a level as they could.  Now that they have the engine that they want for Y-20, I wonder if we will see a huge ramp up here at XAC.  Has their factory space expanded? Maybe something like 40 a year eventually.  That's the level they would need if they want 200 Y-20 and 200 YU-20.
