It is a single section, and about the size of other hangers for one helo.I am more interested in the internal layout. If it's just one narrow, self-contained section, what's the opposite side used for?
The 730 and VLS effectively bisect the rear superstructure, but the 730 shouldn't need deck penetration all the way down to the flight deck, so it should be possible to position the flight control room in the centreline, under the 730, thereby freeing up the right hand side, to allow a second hanger there.
I should have said the rear superstructure. But I am just curious what they have behind the control room that they feel is more useful than a second hanger.
The other side (as mentioned above) is used fro controlling the landings and monitoring it...a flight control center towards the aft portion of the structure (and you can see the viewing station there). My guess is that they use the rest for equipment of various sorts.
There are clearly either storage or equipment access rooms directly below the CIWS. You can see three hatches there under it.
