This is perfect. I believe they do 1 major delivery of transport aircraft every year (or at least that was the way in the past). So, this is probably all of their production for this year. It's hard for me to identify which ones are prototypes and testbeds vs production units. I'm guessing maybe 2/3 to 3/4 of these are production ones Maybe WS-20 ones will take longer time to join service. If I go by Huitong's page, there are probably close to 35 Y-20s in service with the 4th and 13th division + 3 Y-20Us. If I had to guess, the production levels probably looked something like this (maybe a little optimistic for the past 2 years)
2016 4
2017 4
2018 6
2019 10
2020 15
2021 18
This is another case where they can really pick up the production once WS-20 is deemed to be ready. I remember back in most of my years following PLAAF, how they lacked large transport so dearly. Y-20 really is a transformational aircraft for them. In some ways, it's been even more important for China to get Y-20 right than J-20. If they can actually get production rate up to over 20 a year, this would be huge. Again, not something I expected to happen so soon. Ramping up production was always a major issue during those earlier years when I was following PLAAF. It seems to me that if they can keep this going, large transport platform would not longer be in shortage by 2025. If we use USAF/RuAF as reference, PLAAF probably need by 150 in production for various roles.
