take a look to the shadow - it is only the one and first segment, not more
I think lcloo is referring to the second, more blurry picture rather than the first, clearer picture.
In the first, clearer picture it is obvious that based on both the image of the hull itself and the shadow cast by it, that there is only one major grey coloured large hangar/flight deck module that's been added, obvious as seen both of the image of the hull as well as the shadow.
But in the second, less clear image, it looks like there are additional grey coloured "wall" modules added immediately anterior and posterior to the initial grey coloured large hangar/flight deck module. The second, less clear image also doesn't have a good casting of the shadows for us to visibly discern an obvious segment in the same way as the first image.
So it's hard to say.
Regardless of whether they've added additional wall modules, I do think that if the construction of CV-17 was any guide (where it had various wall modules for the hangars added first before the hull openings were closed), it would not be unexpected for 003 to go through something similar.
edit; crudely annotated and not scaled, but you should get the drift.
L side: blue represents the "initial large grey hangar/flight deck module"
R side: green represents additional "wall modules" added.
Not sure if it's the case in real life, but it's plausible. I'm sure we will get pictures over the next few weeks to show us anyhow.
