So far it only reported the 2011 has undergone low speed taxi run, no maiden flight of 2011 prototype.

2011 features several modifications from the previous “tech demoers”, as noted in your post

Finally I think we are getting closer to the real J-20 ‘2011’ or ‘2003’ … come on, and if You like “just leave Your hat on” !

It’s difinitely not “2003”, because the incoming one is the first “prototype”. 20-1-1 means J20 ( 1st 2 digits), the third digit 1 stands for “prototype”, o stands for “tech demoer”, and last digit stands for number of the prototype.

How many “tech demoers” built? it’s difinitely more than the “2001”, and “2002” we used to see, because one of the 2002s have been re-numbered to 2004 in CFTE for the correct numbering.

2014 will mark the service of J10B, 1st in service Chinese fighter with AESA

From top to bottom:

1 New WS10 with black nozzle and longer petal; 2. WS10A with silver nozzle. 3. AL31F

Said to be J20’s AESA, like any 1st image, it’s vague and blur

Plus, Mr. Obama didn’t help………..

Yes, he should have stopped NSA sniffing activities when he first elected. He ate his own words

1) i think so. at first i thought both tpes would be produced at same time. DSI intakes somehow affect super sonic flight and bring down the top speed, therefore compromises its ability in interception missions. But with the weight reduce, better radar, and probably lower cost on the air frames, i found it hard to convince anybody to continue the parallel manufacturing of J10A.

2)i’d rather believe time has been wasted on engines. I can imagine this: “I want WS10As on the J10Bs!” said the official, “We tested it on the J10B, and they just work totally fine with all 3 test flights”, answered the chief engineer. “Then the WS10As works great with the new planes!” “Sure they are.””Now deliver us the Russian engines, we have the 1st block to produce.””OK”.

Your 2nd part surely sounds vivid, but no WS10A for J10B, if the 2nd lot of J10b gets indigenous engine, that will be WS10B
