    In the waterline?


    Look at this drawing:

    If lenght is 248 meters, then width in the waterline is 30 meters. And that seems to be realistic.

    Unclear, but all sources I could find (and I did quite a bit of searching) quote 38m. I see that Jeff Head put the beam at 110ft=33.5m? But based on that drawing, your estimate seems plausible.

    38 meters is correct. But it is not the width at the waterline. This value is nowhere published in the internet.

    They might be waiting for the 003s conventional IEPS system before venturing into even larger LHDs, to make sure they are worth the cost.

    The two dimensional size of the deck doesn't determine the displacement, it's the three dimensional volume of the hull determines the displacement. That's why some of the cruise ships are no longer or wider than a Nimitz class carrier, but they can have three times the displacement.

    Both Chinese 075 and American Wasps and America are designed to transport as much as possible in their hulls. That's why they all look like bathtubs with almost vertical sides and rear. Whereas, Izumo is basically an aircraft carrier that's been called something else for the sake of law.

    The Izumo definitely is not 38m beam at waterline.

    If you look at satellite images of Izumo class ships, you'll find that the flight deck width is about 38 meters, which is why I believe the 38m "beam" refers to.

    The actual waterline beam of the Izumo is closer to 32m.


    .... obviously it goes without saying that a 38m beam waterline ship is a much larger vessel than what Izumo is, because 38m beam waterline is approaching the kind of beam you get out of a 65,000 ton carrier.

    I see there is 2 lifts. One rear and one in the centre (roughly) It doesn't look that big going by the render.

    My question is, I don't see evidence of a side lift so why have one in the centre?

    Obviously the chinese had the US experience to inform their choice, but they have opted for this configuration. I really wonder why?

    So the waterline is at 8.1m which is higher than all previous guessed figures. I remember the full displacement of 31500ton was based on somewhere around 7.5m of waterline, then that figure was adjusted to 36000ton due to the later believe of 8.0m waterline (that was yesterday). Now, it looks more towards 38000ton full displacement which isn’t that smaller than the Wasp class, and with better and more advanced internal design, we should be very confident with the overall result.
