I find it hard to believe that even our more "philosophical members" are not disappointed that progress has been "leisurely to say the least, if it were truly "stagnated" we would not have seen her painted and dolled up and returning to Dalian. I had all but given up on the lovely J-20 until the imposition of the East China Sea ADIZ, and if I weren't lazy and on a schedule, I would find a post or two where I predicted that would "re-vitalize" the J-20 project. Shortly thereafter we see the upgraded 2011 ana 2012, which had no doubt been in the "oven" the whole time, wouldn't surprise me to see 2013 any day as the Russians have completed 5 prototypes, and I do believe there is more than a little desire to "match/surpass the Russians, but the real point is that although the aircraft were "cloistered" there was progress being made.
I would also remind that the Chinese are not ready to go "balls to the wall" against the USN, and doubt that they even find that frenetic pace admirable, or desirable. They prefer to be seen as the careful, "shrewd dude", making the most of a little, I'm sure when we least expect it, we will have another "rockstar roll-out", to pump a little excitement into the populace????
Maybe even a dozen or more J-15s operating off the deck???? anyone else care to comment?????
