As two more (appear to be) 052C Luyang II DDG in Chancing Shipyard spotted under construction, it is nice to have franco-russe around to help us keeping track of the progress
they are launched at roughly six-month intervals:
Hull 3 28.11.10
Hull 4 20.07.11
Hull 5 16.10.11
The hull to the left in Hall 1 has almost certainly no superstructure, so that would be Hull 7, while the one to the right (seen before) is Hull 6.
