New and noteworthy:
Professor Jin Yinan (who is director of the strategic research institute at the PLA's National Defence University) at this conference said construction of China's third aircraft carrier began in March 2015 at JNCX!! 3:57 of the video, and it would be "flat deck, catapult take off". Consistent with known rumours of course.
I assume that means steel cutting beginning in March 2015. If true (and I do believe it most likely is, and corresponds with previous/current rumours), I think we will probably see modules of 002 start to appear at JNCX next year at earliest.
The timing was a bit vague.
Essentially, he said he had given a lecture in Dalian in 2014 where 001A was being built. He said then he had given another lecture in JNCX back in March, 2015, and proceeded to give a brief intro of JNCX: How it was merged with another shipyard in 2010, which is now the builder for 002. Finally he said 002 is currently under construction in JNCX.
So he clearly confirmed that 002 the conventional CATOBAR carrier is under construction currently in JNCX. Whether the construction started in March 2015 is not obvious from his statement. It was a rather off-hand comment, and Chinese language does not have tense.
But clearly it's newsworthy, coming from a rather authoritative figure.
