Two 054A FFGs of the latest batch moored at the distance, with pennant numbers likely to be #543 and #580. Posted by @笑里Cang刀 on Weibo.
Do we know the size of the latest (sixth) batch? Wikipedia says 10, for a total of 50, but only 6 have been observed so far. With the 100mm gun and the ability to carry the Z-20F it's quite different to previous batches.
The fifth batch is often listed as having an extended helicopter deck as well, but I measured on satellite images and it doesn't seem longer and given that the entire hangar area was redesigned for the sixth batch it probably can't carry the Z-20F.
