    Well, 055 does use modular construction yes, based on what we've seen. Most if not all Chinese warships in the last decade or so have been built in that manner.


    Unsure how many personnel 055 may have, and like I said I wasn't too sure just how many personnel 052D has either.

    Thanks blitzo. I see that your estimates match very well mines that i posted in this forum in june 2015 based on the satelite photo of the wuhan mockup:

    Close; that said my estimate for the bow and stern sections do not include the completed bow which will likely take it up to 180mish, and the difference in beam of 0.5m while not seemingly big would have quite significant consequence for the ship's displacement.

    But overall, the projected completed length for this ship is quite close to what many predicted back two years ago when the mock up first emerged. The beam however is a bit smaller than some predictions, like 21m-23m range.

    That said, back then I wasn't too confident if 055 would end up approaching 180m in length or closer to 175m.

    Close Slava Class, less big than a Zumwalt mainly less futuristic less automated, Chinese don't like progress to big steps also.
    But wide as all recent combattants which are more than before, stability matter ?

    I think power plant limitation definite played a role on ship size. China doesn't like to rely on foreign imports for major weapon systems if it can help it. Look at how Russian frigate programs are doing with Ukrainian engines. And warships take many years of design and planning before construction can start. I bet 055 program didn't get the approval until Ukrainian gas turbines can be produced domestically.

    Another factor is logistics. PLAN didn't start major replenishment ships construction until recently. Bigger ships burn more fuel.

    QC-280 engine is not a clone of ukrainian engines. Its a more powerful version, at least thats what been mentioned in this forum. But i dont think that there is certainty in this, so perhabs it could be a clone. IDK

    ok, until foreign technologies have been digested.

    I'm a bit disappointed that the beam is only about 20.5m, with length at 180m, full load displacement at 13,500t and propulsion rated at 4 x 28 MW.

    Here are the corresponding numbers for some destroyers/cruisers in more or less the same class:

    Type Length (m) Beam (m) Full-load (t) Propulsion (MW)
    Arleigh Burke 155 20 9,200 4 x 19.8
    KDX-III 165 21.4 11,000 75
    Atago 165 21 10,000 75
    Slava 186.4 20.8 12,000 97

    052D 156 18 7,500 2 x 28 + 2 x 6

    QC-280, the gas turbine that 055 and 052D use, is rated at 28MW. Even at a lower rate of 23MW, as some claimed, the combined power output is still larger than most of the above ships with the possible exception of Slava.

    I had thought they would go for a beam of at least 22m.

    Depending on how one measures it, the beam might be up to 21m, because the "crease" which is the widest vertical point on the ship is lower than on other past ships which may make it satellite measurements for beam not as accurate.

    A 20.5m-21m beam is a bit lower than what I expected; I thought it would probably be closer to 22m as well, but given it also has a likely total length of 180m I am still pleasantly surprised overall.

    length to beam about 9:1 ... a view from the angle like below will be cool:
