    The stretched 052D is 161m x 17m. The aspect ratio (~9.5) is hardly the highest among other PLAN destroyers. That distinction belongs to Type 051 (132m x 12.8m, ~10.3).

    That array at midships looks strange. Is this a longwave radar of some sort for anti-stealth?

    They also took out the two X-band SATCOM bulbs amidships which previously is just situated front and below the metric wave radar, and replace them with a single one on the back just above the hanger door. The small white bulb that used to be there, which is either a Ku-band SATCOM or a missile datalink, is now moved ahead of the X-band SATCOM bulb.

    Another thing of change, although this started around the 10th Type 052D, is the ESM unit. Previously, they looked like this going all the way back to the 052B. They are similar to the DWL002 passive sensor, which in turn is similar to the Tamara, Kolchuga and the earlier VERA units. Capabilities of the past and the new ESM are unknown and vaguely documented. These sensors work on threes, two will give surface or bearing location information, and the third will give altitude information. On ships however, two will only be used.

    Newer ones had a more of a capsule shape.

    The newer ones remind me more of the VERA NG. Remember this? Back in 2006 or 2007, China tried to buy these from the Czechs but the US blocked it. This one with the rounded cap is a much more recent design, around 2015 and up.

    The rounded, more capsule form ESM is also partially hidden on the Type 055 --- you will find them near the base of the mast. They are also found retrofitted to at least three, maybe four of the 052C, and given the rate of progress and intention, all six should be retrofitted. The new ESM is also retrofitted on the Liaoning earlier this year when her communications equipment and bridge was overhauled.

    This overhead picture of the 052C and 052D together shows the new ESM on the 052C.

    It's strange you would use turbine-to-VLS ratio to judge the merit of the two platforms.

    I guess. I am assuming the turbines are the major portion of the cost of the vessel. I could be wrong though. Perhaps it is electronics and then it makes more sense to use the larger vessel.

    If crew is the major funding issue in upkeep costs then the larger vessel is better.

    I think it is the electronics.

    For the Type-52D, there was a quote that half the cost was electronics.

    Remember that a long range Sam system like the Russian S-300 is about $200M and a S-400 is about $600M.

    There is also a lifetime cost breakdown publicly available from the US gov, which includes the Arleigh Burke amongst the numerous weapons systems. Personnel and gas turbines aren't significant.

    So you can use that to estimate what the equivalent Type-52D cost breakdown would be.

    IIRC the radar in itself cost 1/4 of the ship !
