The current stage with most of the superstructure being a placeholder with a multiple parts being "borrowed" for that use to get the general gist of the shape.
The aft below waterline is also a placeholder as I'm trying to figure how to make it look like a proper trimaran and I can't seem to get the bow quite as I want it to look like. As a bonus a prototype railgun above the aft flight deck.
Pretty much everything forwards of the aft deck is a subject to change as I'm still trying to nail the aesthetic of the ship so that it will look like it could actually exist.
Now then for the actual design. Starting from the rear we have a flight deck with elevators on both sides to get anything and everything that flies from the hangar up to the deck. We also have a rear door/ramp/whatever the real term is for deploying the naval infantry units for coastal assaults and landings.
The rear "island" is mostly a C&C center for aviation and landing operations and anything in between. So in essentiality it handles everything outside the ship.
Then there is an elevator on both sides in the middle where the secondary hangar is located and this is used mostly for the VTOLs (cuz durr) and/or heavy troop/cargo helos.
The primary "island" is the brains, brawn and looks of the ship as it is where all the magic happens. The bridge, the C&C for it's armament, radars and sensor are all operated from somewhere within here.
The front deck will most likely be stuffed with VLS systems ranging fron your regular SSM/SAM missiles to nuclesar capable launchers, much like the Russian/Soviet Kirov class battlecruisers.
The main armament will be the railguns which I'm yet to decide 4 per side or 2 along with the massive VLS ordnance it carries. It in it's current state has 8x Kashtan CIWS for any nasty buggers that get close.
