This one (156) went to the Sixth Destroyer Flotilla of the ESF. This is an accomplished formation, somehow got four 052C (150 to 153), 154, which is their first 052D, 155 which is a strange 052D as it is a hybrid of 1st and 2nd batch features, and now 156. Even after this, they still got more 052C than 052D.
There should be another Type 052DL in advanced state of trials, which means, based on PLAN's new revised procedures for doing such, the weapons and acceptance trials are being done by the PLAN.
New radar is not an L-band. While it is a new antenna with more elements, it still runs on UHF.
