Excellent info, and analysis xiabonan. Very much appreciated as it whets our appetite for what we all believe is coming...that is two carrier being constructed simultaneously in the PRC.Liaoning's Provincial Party Committee Secretary has just said publicly that "after the commissioning of the Liaoning, China's second home-constructed aircraft carrier will start construction at Dalian, with an estimated construction cycle of 6 years, together with 2 other 052D guided-missile destroyers. "
First, this MAY or MAY NOT be reliable. But I believe it should be as it corresponds to what we have known so far (North and South each will build a carrier, with the North start the construction of 052Ds). Although the number of 052Ds does differ from what we have known (2 vs 4).
Second, in the original report what he said was "国产" which literally translates into "country-made" or "country-produced" or "country-manufactured". So, by "second" he could mean that Liaoning is the first OR he could mean that the carrier at Shanghai has already started construction (which may be those structures we have seen in photos).
These are just some of the possible interpretations of his words and some of my own speculations.
But, as with all things, it is time that will reveal what actually happens.
