If trend continues we should be seeing 3-3x come end of 2017
Batch 3 and mid 30s in number
J10C upgraded with WS10B and CFTs should warrant a J10D
Is a J10D even possible? In my opinion certainly yes, if a designation was ever in question it should have been J10B to J10C since it's minimal changes
There was a pause in 2015 in between J10B and C so we could be in that pause period right now in between J10C and D
Only CFT would warrant a new designation as a few J-10Cs already fly with WS-10Bs and they're still called J-10C. However, there has been very little information on CFT development by the PLAAF; a few video screenshots here and there, and that's it. So, it's doubtful that the next J-10 iteration will incorporate a technology that we've been hearing little about. If it does, consider me very surprised.
