This will be cross-posted with the 052C/052D Class Destroyers thread.
The photo was likely taken at the same time as the most recent overflying photo of Fujian at Jiangnan with the KJ-600 and what-looks-to-be C-2 counterpart on the flight deck.
Seen are the hull modules which belongs to 4x DDGs:
#1 - The 2nd unit of the 2nd batch 055 DDGs built at Jiangnan (seems like the construction and assembly is taking quite a long while)
#2 - A bow section, likely belongs to a new 052DG DDG
#3 - A bow section and a mid-section, both likely belong to a new 055 DDG
#4 - A bow section, likely belongs to a new 052DG DDG
