Ok PLAAF regiments with J10A/S with 43, 1,2,3, 24,9, 15 and 72
PLANAF yes just 12th regiment 4th division
My own calculations would say around 250 units
Add to that August 1st demo team
FTTC aggressor squadron
Does Chendgu have some units?
Add another 30 units to give 280 or so
Not far off the 300 tally
Sorry, but there are few errors included ... seems as if You are mixing regiments and divisions:
1 AR is a J-11B unit (1. Div)
3 AR uses J-8F (1. Div)
9 AR has Su-30MKK (3. Div)
15 AR has JH-7A (5. Div)
24 AR has H-6K (8. Div)
43 & 72 AR is correct
All I have:
PLAAF-regiments are the 2, 5, 8, 26, 34, 43, 72 and 131 + Ba Yi
PLAAF-brigades are the 124, 170 (FTTC)
PLANAF-regiment is the 12
---------------------------------------
As such thru a rough estimation these are 11 operational regiments or brigades with 28 aircraft each = 308 aircraft.
The FTTC and Ba Yi have smaller numbers - maybe only 8 (FTTC) - 12 (Ba Yi) - so these would be 20 .... all without the recent und still unconfirmed J-10B units (said to be three already, however the 5 AR replaced its A with B-models but I don't know, who gained their old A ?)
.... so about 308 + 20 = 328 early model J-10A/AS operational !
Compared to my estimated production run of 232 J-10A + 90 J-10AS = 322 aircraft I would say it fits nicely.
