it never hurts to have one more set of measurements.
I used both the drydock dimensions and the shelter dimensions as base, for double security factor.
Tried to take into account the slight off nadir angle of the image, which may make the carrier a bit longer if not carefully choosing the stern ending point.

Anyway, I am getting this:
317 m overall length
80.5 m overall deck width at its widest point (but not taking into account any possible antenna/rail protrusions)
76.3 m deck width at mid point.
Elevators are 20 m by 14.7 m in dimension
Catapult length seems to be 109 m.


How does that compare to Nimitz for example. Also measurements taken via GE, not just using readily available numbers:
333 m length
78.6 m max deck width
76 deck width at mid point
Elevators are 15.5 m by 20.8 m/25.6 m.
Catapult length is some 106 m.

*of course, all these are subject to errors due to low resolution. So a meter or two here or there is quite possible/likely.

So indeed, quite peculiar that PLAN decided to have a carrier with a smaller and narrower hull feature a deck even slightly wider than a Nimitz. And on a deck shorter than Nimitzes, to have a catapult slightly longer than one on Nimitz.

Given all this and my previous displacement estimates, I'd say 003 should be right around 80 000 t. Give or take a few thousand tons.
Could you please explain which is the length and which is the width of the elevators.

Given the estimated displacement, a better comparison is the Kitty Hawk:
Waterline beam: 39.6 meters
Length overall: 326 meters
Extreme width: 86 meters
Full displacement: 83000 tons

As we can see, the Kitty Hawk was quite a bit wider than this carrier and significantly wider than the Nimitz class despite having a 4ft narrower waterline beam.

Are you measuring the drydock width as 80.4m wide? Because the set of measurements done by horobeyo on twitter was based off the drydock internal width being 82m wide, from contractor documents for the shipyard back in the day.

In any case, the general size of the ship is already pretty clear.

The waterline beam of the ship is within spitting distance of a Nimitz (~0.5 meter within range, depending on the measurement).
Extending the ship's flight deck to be Nimitz/Ford length would've required a commensurate increase in hull length and displacement. Can't see that happening without at least a further increase in propulsion output, which may or may not have been viable.
Yeah, my figures were based on both the dock and the shelter width, was getting the same number for both. As said, with such low resolution end results likely do contain some errors.
If for example I use 82 m as drydock width, I will of course get bigger figures for width. 81 m wide deck at its widest. And 77 m wide deck at its mid point.

I was getting bigger difference in waterline beam than 0.5 m before, compared to Nimitz, but that's not a topic I can repeat discussing right now.

Could you please explain which is the length and which is the width of the elevators.
In my context, width is bigger than length. Elevator Length is parallel to ship's width. And Elevator width is parallel to ship's length. So i guess it can be a bit confusing the way I wrote it.

Why do you think that propulsion power output was the limiter in making the ship 5% longer?

, the goto reference for USN vessels. The source you referenced has bad data for the overall length and flight deck width.

If you analyze the satellite photo below, you can convince yourself that the USNVR data is correct. My estimate for the extreme flight deck width is 82.5m. The width of the flight deck between elevators is 72.3 meters (not including the safety extensions). This is less than the 76m for 003, estimated by @Totoro, but very close to the 73m estimated by Naval News.

Are we 100% confident the internal drydock width is 82m? The Naval News piece pretty much affirmed the estimated length of 003 at about 320m but estimated flight deck width fell well short.

Extrem bean or width, is not fly deck width. The parameters have to be the same to be able to be compared.

I measured the same region where the flight deck reaches its extreme that @Totoro measured for 003. The parameters are the same. I've no idea what your German source measured. Do you?

Red = extreme flight deck width = 82.5m
Blue = flight deck width between elevators = 72.3m

If you weren't lazy you would've done the measurement yourself and saw that it checks out.

Anyway, I used the same image @Totoro used, with his pixel size estimates, but I got 74.5m for the middle section width of the flight deck for 003. The line he drew was not parallel with the lateral axis.
