There is an estimate waterline length of 300 meter plus or minus 5 meters, comparing to CV-16LiaoNing's 270 meter waterline and USS Ford's 317 meter waterline. The final full load displacement is expected to be around 90,000 metric tons according to many discussions in China. The displacement of type 003is surely a bit than the USS Ford's but technology wise I believe is definitely a rival to the Ford class in terms of EMALS and electronics on board. Also, the width of the rear section of the ship is almost the same width as the mid section, and this is different from Ford class which has a narrow rear. Type 003 is still going to be a nice Supercarrier no matter what haha
What is the source of that estimate?
Based on previous estimates posted on this forum, the expected waterline length is 318m. Waterline beam appears to be ~39.5m-40m. Displacement cannot be estimated based on these two figures alone. The missing variables are draft and the block coefficient or the "finesse" of the hull. Photographic evidence indicates that this hull is significantly finer than either the Nimitz or Ford class and more comparable to Kitty Hawk class. With these assumptions, the upper estimate of full displacement is around 86,000t.
Ford class full displacement is not published, but is understood to be larger than the Nimitz class which displace around 106,000t.
The next relevant thing to watch for are the hangar dimensions. After that, the flight deck dimensions. That will give us good idea about the power of this ship.
