No prototype bort numbersHow can people tell it's a production J-20A?
No prototype bort numbers
The J-50 may not follow the same procedure as the J-20. For one, one is SAC and the other is CAC. Second, the J-20 has been following the same procedure with numbering for prototypes vs none for production planes for a decade plus now. Third, there seems to be multiple J-20As without borts.By this logic is the J-XDS/50 already in production? Not necessarily even in LRIP, but at least beyond EMD?
To date, not a single J-XDS airframe has been seen with bort numbers. And we've had lots of good quality photos of its underside and even on the runway, and overall these include at least a version with a pitot and a second version without. We've also not seen any major external structural changes (apart from the aforementioned pitot) as a stark comparison with the J-36 prototypes.
There's not enough photos of J-50 to say it doesn't have bort numbers. It could simple be on top of the airframe or somewhere else. Shenyang usually puts their serial on the vertical stabilizer for J-35s however J-50 doesn't have any so it could be anywhere and judging from J-35 they could also tiny in size.By this logic is the J-XDS/50 already in production?
