By the way ... since we are onto these new H-numbers on PLAN aircraft and especially J-15s I had an idea:
Altogether, five blocks of H-numbers have been identified on J-15s with xx = number:
1. H11111xx for all xx = 01 to 24
2. H17410xx for all xx = 30 to 35 & J-15S no. 46 + 49
3. H11011xx for all xx = 60 to 69
4. H11021xx for all xx = 70 to 79
5. H11031xx for all xx = 80 to 89
So far I wasn't able to deduct a pattern of which single seater was seen on which carrier and IMO they are assigned as per request on which one is available, but these H-numbers make me suspicious and my theory is:
- the nos. 01-24 are some sort of OCU at Huangdicun
- the J-15S and nos. 30-35 are a training unit at the NAU (also at Huangdicun ?)
- and the final three - most likely four - blocks of ten aircraft each are "operational flight groups" (daduis ?), which will either be permanently be assigned to a certain carrier or as per duty.
