You probably missed or forgotten this picture which was posted in this thread earlier and in the 052C thread.
Its a pretty good bet its a warship, due to the lines and shape of the side that suggests RCS reduction. But it looks more 052C than 054A. The shipyard is Huangpu.
no, I remember that one, I'm just saying that one doesn't look like its in the 054 class. Maybe we will see one more like 054A at the new HP shipyard.
