May be PLAAF and Chengdu AVIC is doing something so incredible that is beyond our belief. They could have decided to open "the long rumoured 4 assembly lines for J20" and decided that batch 7 production-run should be stretched over a period of more than 12 months.

China is always capable of doing things beyond our expectation. May be this is one of them.

Potentially yes. By anywhere from 20 to 50.
hmm, that might be a high estimate. Remember, when we used that method, we had always assumed that the last number was the highest it could be, because we had in our mind how many J-20s there might be.

If we now assume batch sizes are about 24 each and that the 7th batch was fully delivered by the end of year, then there are about 170 J-20s, which isn't that far off our original estimate. Moreover, if we assessed last year that there are about 100 J-20s at the end of the year, the production rate of close to 70 is still reasonable.

Yeah, hence my earlier comments about getting the answer right with the wrong method lol. But I think it’s more likely now that we are not yet closing on 200, and 20-50 is mostly in reference to that higher count.

Sure but we thought CB0370 meant maybe ~170 aircraft but if the last digits are actually sequential of total production and we have a CB07156 that would mean we are at at least 156 aircraft and maybe/probably higher.


Ok … I think I need indeed to check my image collection and start again from scratch with a theory.
