re: PLAN Type 052 Class Destroyer
Yeah it's pretty clear that this thing is definitely 052D.
The main gun is different (turret itself seems smaller, less bulky than the 100mm and doesn't have the ladders over it), the APAR looks like the one aboard 891 (difficult to tell, it's so blurry but we can't see the shadows of curves ala SAPARS), the windows on the bridge are different (5 vs 7 of 052C or something), even the hull itself looks a little wider (I first pointed this out when the pics of hull 6 and 7s bows protruding out of the building hall emerged. I thought I might have been seeing something that wasn't there, but by the looks of it 052D will indeed be somewhat wider than 052C).
And apparently hull 7 may launch some time next week, so the long wait for 052D is finally coming to an end.
