These things take time, usually years, to work out.
Totally get where you're coming from: billion $ defense transactions can take years to firm up once they're agreed to in principal, especially if some degree of localization/ToT or offsets are involved.
Maybe I'm not paying enough attention or just looking in the wrong direction, but a bit surprised that there haven't been any reported tire kickers except KSA.
Was also told that many civil operators of the Il-76 that would be interested in the Y-20 bought their Il-76 airframes second hand at discounted rates when the collapse of the USSR apparently glutted that market for years, and won't be able to afford shiny new Y-20s. Not sure how true that is, but could be a factor. Who knows . . .
IMO highly unlikely if not simply impossible based on all images we have, based on all known/confirmed serial numbers we get in certain intervals (I know we are always late, but not about 50 aircraft), based on the known units ... and even more it simply makes no sense at all!
That's fair. I know you've been watching the PLAAF for a long time, so appreciate your assessment here!
Obviously not going to hold you to this, but if you're to ballpark it, how many Y-20 airframes of all varieties do you think XAC is cranking out yearly?
