Union-class trimaran CVBN

Named for the union of the two kingdoms of Isselmere and Nieland, the Union-class will serve to reduce the number of vessels operated by the Royal Isselmere-Nieland Navy without incapacitating any of its warfighting capability.

Design
The Union-class has been in development for several years now, the lengthy design stage being necessary to minimise the safety issues that arise from the operation of multiple landing surfaces upon a single vessel.

All eight of the Union-class's aircraft lifts are well-clear of the landing areas, as are the six armoured ammunition lifts. The deck-edge lifts are located aft and the inboard lifts are located fore, aft of the forward flight deck. Great efforts have been taken to minimise the radar returns from the deck-side lifts with some success. The inboard lifts are at the edge of the primary hull.

Flight operations
The microwave automated carrier landing system (ACLS) uses radar, optronics, and secure datalinks to allow the Union-class to land conventional landing (CTOL) aircraft in rapid succession onto its three landing areas. The ACLS is designed to land each aircraft on the number three (of four) wire. Once the senior flight control officer (SFCO) assigns an aircraft to a specific landing area, the aircraft is guided down by a secure datalink that permits no confusion. The two standard-length landing areas do not intersect one another. The broader extended length landing area, angled at 8.5 degrees to port, is for larger aircraft and partially intersects the standard-length landing area angled to starboard.

Two electromagnetic aircraft catapults (electromagnetic aircraft launching system; EMALS) are positioned on each secondary hull sponson, with four EMALS, including two heavy systems, located on the forward flight deck.

The Union-class is equipped with two small islands -- one on each secondary hull -- for antennae and flight control observation that have been designed to minimise both the returned signature from electromagnetic devices (radar, infra-red) as well as the air turbulence caused by such structures.

Ship's operation
In most instances, the Union-class is controlled from the command centre (CIC) using optronic information from eight remote piloting stations (RPS) and other sensor data "piped" down through EMP-hardened links to the "bridge", offering the ship's crew an all-encompassing, panoramic view of possible hazards. This network of systems permits the Union-class to be berthed from the CIC, although more traditional methods are generally used.

Armour
The Union-class has been provided with the heavy armour of its predecessors, enabling the massive vessel to contend with many anti-ship missiles as well as smaller battleships and cruisers should the need arise. The main strength deck, however, has been lowered to the hangar deck, owing to experiences with the Peel-class carriers. Though the decks had protected the carriers from harm, the damage required extensive repairs due to the transference of impact throughout the structure, more so than would have been required had the shipyard been able to simply replace the affected section. Future RSIN aircraft carrier designs will likely incorporate the same design philosophy as that implemented on the Union.

The armour scheme is a lighter version of that used on the Europa- and Jimnam-classes. The structural basis for the ship is of titanium-vanadium-aluminium (TVA) alloy to cope with the stresses large trimaran vessels must contend. The framework is supported by bulkheads reinforced by hardened crossbeams. The outer shell of the vessel is covered in insulating, fouling-preventative laminated ceramic tiles, upon which is laid an additional environmentally-friendly synthetic rubber anti-fouling surface. Behind these initial layers of protection are tubes of very high hardness steel (VHS) within kinetic energy resistant insulation (KERI) foam that are intended to attenuate the blast effects of any projectiles able to penetrate the first armour layers. Braces of TVA ('spacers') between the outer and inner hull provide an additional layer of defence. The next layer of high strength steel is buttressed by further crossbeams in case of outer hull failure, as are the longitudinal and transverse bulkheads, followed by an additional void space filled with KERI foam before the secondary hull of high hardness steel (HHS). Another layer of KERI foam serves to provide some anti-spalling protection along with a sandwich of ballistic polymer fabrics and a honeycomb of high strength composite.

The Union-class's torpedo bulkheads are at twenty-to-thirty degree angles from the vertical, while the keel is provided with another layer of TVA armour to counter under-keel torpedo attacks.

OOC: the cost, "Cost: $64,000 million USD", is it 64 million dollars (64,000,000) or 64 billion dollars? (64,000,000,000)

$64 000 000 000 = $64 000 million = $64 billion (US definition)

$64 000 000 000 = $64 000 million = $64 billion (US definition)

OOC: Trying to make the price seem smaller? ;)

For $4 billion less I can get 6 Nimitz carriers, an escort fleet for each, an army, an air force, and a marine corps. Also that number of carriers can support more than twice the number of aircraft making a much harder target to hit. Offer an escort fleet to justify that obscene price.

OOC: ...and how can taht, in any way, replace this carrier because you can use the same price to afford six ships built using designs influenced from the 1950s and get some random destroyer that can be damaged by a .50cal hit on the hull as your so-called "escort fleet"? Or for the matter of fact, how are you in the position to assume that combat performance is automatically multipled just because there's a greater number of aircraft and ships? And what's the relevancy between these "army, air force, and marine corps" units of yours when you can't even deploy it from the ships you described?
Using this same senseless and ridiculously flawed logic, we can sufficently conclude that we can buy one hundred PCs from '94 with 486 processors, network them, and say that it's a replacement for a single computer with a new gaming machine from '05. Employing this same logic, we can also state that the procurement of fifty F-16s is stupid just because you can buy 1000 P-51s for the same price.

It's a very nice ship and an elegant design, but comparing it to a fleet of six Nimitz CVNs proves no point other than the amount of flaws such direct comparison possesses and the senselessness that it exhibits.

A comparison to Isselmere's vessels to American vessels is an insult. I demand you apologise at once, naval notknower. Otherwise it's a damn good aircraft carrier.

You patently have no understanding of present-day costings for any of the above. The most recent American carrier will cost the US Navy about $8 billion (before its air wing), the escort fleet (destroyers and cruisers going for about $1 billion per unit, plus helicopters; submarines for about $2 billion a go; etc., etc.). Furthermore, whilst 6 Nimitzes could reasonably support 480+ aircraft -- and if you really wanted to, you could cram upwards of 300+ aircraft onto this ship -- the Union-class has more armament, more sensors, more armour (which tends to be quite expensive), a larger hull, etc., etc. Besides, of the aircraft I had listed in the provisional outfitting, several are larger aircraft that can't be operated from the "small" deck of a Nimitz-class carrier.

In addition, if you are unable to offer a reasonable argument delivered in a reasonable manner, I suggest you find somewhere else to blether inanities.
