China may have 370 J-20 fighters / interceptors
From the Zhuhai airshow, citizen analysts have recorded the serial numbers printed aft of the cockpits on two J-20As, as CB0369 and CB0370 respectively.
This has come as quite the surprise.
Excluding other explanations like a psy-op (to persuade us in the West of a larger inventory than is real), or a change in serial-labelling on account of a new batch designation scheme, these serial numbers indicate that China may have around 100 more airframes than was previously thought.
The J-20A, while manifesting a cruder design than those produced by Chengdu's more experienced Western counterparts,
complicates a Western intervention in Taiwan somewhat.
The J-20A's ability to assault lumbering support assets (AWACS and tankers) from afar produces problems for Western tactical fleets in the expanses of the Western Pacific.
It is already known that China's domestic aerospace industry has settled on mature designs in many classes of aircraft (Y-20, Z-8, Z-10, Z-19, Z-20, J-10, J-15, J-16, Y-8, Y-9, C919 etc, etc, and etc). Production lines are known to be ramping up (particularly on the J-16 line/s). Nevertheless, this could be a large and impactful shift in our understanding of their 2022 inventory and projections for a 2024-2025 inventory.
