The advantages of a multi-hull carrier are stability, survivability and interior volume.
Some proposed trimaran carrier designs incorporate a flight deck that spans across the top of all 3 hulls but the hangar is still situated within the central hull because the outer hulls support the flight deck only. In the design of the Sea Command carriers the hangar also spans across the top of the 3 hulls, maximising hangar space to the full beam of the carrier. The width of the flight deck is further increased due to the flared sides, bow and stern of the superstructure, this also helps reduce radar signature. The outer hulls extend beyond the length of the centre hull for greater protection from a side on attack as the centre hull contains the 2 Nuclear reactors, fuel supplies, command centres, weapons storage, amphibious deck and other vital areas so this protection is paramount.
The crew accommodation, usually made up of smaller spaces is contained within the part of the superstructure situated between the centre and outer hulls and below the hangar deck. This allows protection with the outer hull, separates the accommodation from the centre hull (away from the fuel and weapon supplies - for better fire protection) and gives easier access to the hangar. There is a small launch bay for rescue / mission RIB`s contained within the side of the centre hull amidships.
The 2 door openings on the superstructure front, contain each, 1 gun and 1 missile launcher, the openings on the underside each side of the centre hull contain the anchors - these doors protect from heavy seas. The 2 pointed triangular shaped structures protruding outwards from the front of the superstructure help strengthen and also protect from heavy seas. The forward outer hull extensions contain countermeasure systems while the aft extensions contain 1 gun, countermeasures and 1 missile launcher each - for aft defence.
The hangar is served by 3 large 100 ton lifts and 2 weapons lifts, the aft aircraft lift serves the flight deck, hangar and amphibious deck. The lifts are centrally located within the hangar to provide support for the wide flight deck above and also allow access from either end, their position means that the sides of the hangar are fully enclosed allowing for a good amount of armour protection. Each lift is large enough to carry 3 jets or 4 UCAV`s (depending on UCAV size).
There is enough space for aircraft to be moved around between parked aircraft and the lifts. The forward part of the hangar has bays for engine and drone maintenance, the main hangar is separated into 4 large bays, 1 each side of the lifts and 1 at each end.
The flight deck has 2 longitudinal landing strips and 5 EMALS catapults, the central one launching larger aircraft. The area aft of the lifts is for helicopters and other VTOL aircraft, the aft weapons lift serves these aircraft for arming. The weapons lift situated forward of the lifts is for CTOL, STOVL jets and UCAV. VTOL aircraft or even VTOL UCAV`s can also take off and land along either landing strip. Between the actual flight deck and each island structure is an area for parking the crane, fire tender, towing trucks and pallets, this area keeps these vehicles and other off of the flight deck allowing a more free space for aircraft.
The islands are set 'off 'of the actual flight deck area, reverting back to some kind of ' flush deck 'design afforded to early carrier designs like that of HMS Argus (1918), they are also angled outwards away from the flight deck for added safety. This location of each island gives an unobstructed view of the whole flight deck and also a view down the side of the outer hull as well as out to sea. The structures are narrow (to help reduce wind turbulence) and only widen at the top to give more space for the integrated Fly Co / Ship Control room. They are constructed from light composite materials with radar, communication and other systems` antennas incorporated into the island structure itself, the islands are also connected via a passage way (between flight deck and hangar ceiling) for ease of access. They are positioned slightly aft of amidships to allow equal viewing distance to the cats and to the traps. As well as the island structure, each sponson also supports 2 guns, 2 banks of 16 missiles, countermeasure systems, domes for communication, life rafts and landing aid.
No specifics on exact types but there are 8 guns (possibly laser of some kind), 4 missile launchers - each launching 6 missiles, 4 banks of 16 missiles and an extensive amount of countermeasures to aid defence.
Around 120 aircraft would be normal with the number of helicopters being around 8, but the number of helicopters would increase for aid support role. In 20, 30 or even 40 years time UCAV`s may make up the majority of strike aircraft within the air wing, a squadron of small surveillance / search and aiding rescue 'scout ' drones (about 50 or so) could also be included - used to survey and search flooded, Hurricane / Typhoon and earthquake hit areas.
In aid support role Sea Command is transformed into a warehouse for storing and transporting a huge amount of aid and other equipment like bulldozers etc, (essential for crisis hit areas) or even used as a temporary hospital able to treat thousands of people if the situation ever arose, with the carriers carrying portable desalination plants for clean water as well as tents and portable medical units as standard all transportable by air and by water. So in essence these carriers would be a complete fast, safe and very capable aid transport and delivery 'work horse' with the added bonus of super carrier and amphibious assault capability rolled into one for combat role.
