Thanks. How many J-11B block I are there?
I think Block I's are the first batch of 20-24 J-11Bs entering into service in 2008 and also participated in the 2009 Parade. All of them belong to the First Division in Anshan. It seems like the same guys from Anshan are participating in this year's parade. The rest are Block IIs (and Block IIIs), I think. As of the difference, I think the major one is the adoption of WS-10A engine for Block IIs and beyond. However, I don't know much beyond Block II. I was guessing. Sorry

! The Navy also has J-11Bs and BHs, so that could potentially be Block III. Also, everything I said here are based on memories from Chinese articles from 2013 or earlier, so they could be completely outdated info.
