Marked as secret IC since the lead ships of the class are currently being constructed somewhere where spy sats or "tourists" with cell phone cams can't go. =p.

This is very much PMT.

Notes: Intended as the lead ship of a new class of battleship known as a "Strike Battleship"; vessels of this type are meant to operate alone rather than part of a fleet and excel at raiding and hit and run attacks and especially commerce raiding.

The antiaircraft array is unique in that it is primarily energy-based; it uses a combination of Ra Kai Quantum Cascade Pulse Lasers and Raptor Kai maser systems. The lasers have a range of line of sight, and their output is sufficient to not only easily destroy missiles and aircraft, but actually engage incoming shells and at closer ranges, damage other vessels. They are run on an ultraviolet frequency which allows them to penetrate clouds, fog, and smoke more easily.

They are backed up in their task by Ra Kai maser arrays, which direct a wide-area beam of microwave radiation that fries the electronics of missiles and can damage aircraft, though their range is far shorter than that of the lasers.

Finally, there are numerous 20mm super rapid guns firing caseless rounds.

Missile armament consists of a mixture of surface to air missiles, medium antiship missiles, and cruise ASROCs carrying Delta two-stage 933mm torpedoes; these torpedoes are two-stage weapons, utilizing a "cruise" stage to close most of the distance to their target and a "burst" stage, where in their terminal run they eject the cruise section and use a supercavitating drive to close the remaining distance.

Primary gun armament consists of eight "Valient II" hypervelocity linear guns; based on technologies developed from study of the 78cm weapons utilized by Bretton's A7V Peacemakers, these weapons are capable of hurling rounds more than 800 kilometers away, though in practice, accurate range is at most a quarter of this. The primary type of round used is the "Geniestange" guided projectile; this is a shell with aluminum driving bands and small thrusters which allow it to deflect it's angle towards the target somewhat. It has a small targeting package to allow it to pick up something at closer ranges.

While a more maneuverable projectile was desired, the immense muzzle velocity of the Valient II unfortunately precludes this.

Secondary gun armament are a number of super rapid 155mm caseless cannons; they are capable of raining down a high-speed barrage of fire at ranges of up to 40km. They are capable of acting as dual-purpose guns when neccesary, though the trasverse speed of the turret means they are not the best weapons against aircraft (though they would do fine against airships, such as those Axis Nova or Fourheats uses).

Tertiary gun armament is served by the Ra Kai Quantum Cascade Lasers, which while primarily anti-aircraft weapons, can also serve against land and sea targets with equal efficiency. Unlike conventional solid-state lasers, the optical transitions occur between electric subbands rather than between the conduction band and valence bands. The "cascade" is a series of equal energy steps built into the material matrix while the crystal is being grown. When the electrons are transmitted through the laser crystal, they emit one photon at each of these cascade steps, unlike diode lasers which only emit one photon per electron transmitted.

This leads to greatly increased efficiency, though laser crystals do tend to degrade over time and require replacement every few hundred shots (a rotating revolver-style loader is in place to facilitate this) and due to their extensive use of superconducting materials they are quite expensive.

Antitorpedo armament is provided via several blue-green lasers; operating at frequencies water is more transparent to, they are able to predetonate torpedoes at a greater range than conventional supercavitating CIWS guns, and due to being lasers, they are aimable simply via prisms extended from the hull rather than a bulky gun, increasing streamlining.


Propulsion uses two separate systems; the primary is a pair of underwater thermonuclear ramjets. Using a fusion reactor to superheat and vaporize water passing through them into a plasma, the plasma is then focused and expelled from the back of the ramjet at high speeds, propelling the vessel forward also at high speeds. Acceleration is quite quick, though the ship needs a rather large amount of distance to stop. Course can be changed rather quickly with the ramjets in operation, simply by reducing power to one to create a thrust imbalance.

When a more sedate pace is called for, propulsion is provided by a trio of 9-blade propellers.

Finally, the I-Type mounts an extensive battery of ECM equipment; it is well equipped to jam radar over a large area, allowing it to operate in a blind spot as far as anything nearby is concerned.

OOC: If this vessel is intended to be a large, slow moving vessel, then it suits its purpose.. However, if you intend to have a little more straight-shot speed, you should design something around a wing-in-ground effect craft, where the craft actually floats ontop of the surface of the water, http://docs.hydrofoils.org/wig.pdf see that for more details of how this actually works in real life. :)

Nothing that weighs more than 100,000 tons is going to be a hyrofoil. =p

Actually, it uses ground effect, it isnt a hydrofoil... Besides, people also thought the 747 wouldnt fly because it was too heavy.. it'll just require a higher speed for the ground effect to work..

With ground effect, the entire ship is actually 1-4ft above the surface of the water, there are NO ship parts in the water, unlike a hydrofoil which is still residing in the water itself.
