Yashima-class battleship

The **Yashima-class battleships** are the most powerful warships of the Yamatai Imperial Navy in terms of direct weaponry.

## Naming convention

Due to their power and importance to the Imperial Navy, the Yashima-class battleships are some of the few ships in the Imperial Navy which have unique names. While some rare examples have personalised named from particularly cherished Navy commanders, the majority of Yashima-class battleships are named after the core Shinto gods, generally with the word Storm, Tsunami, Cyclone, Typhoon, Wrath, Hammer, Blade, Spear or Sword accompanying the god's name.

## Specifications

### Armament

#### Primary armament

What is often considered the main weapon of the Yashima-class is a ventral dual turret with two long-range multi-purpose 800 millimetre railguns capable of targeting enemy warships and bombarding enemy planets. They are particularly potent at dealing with orbital platforms and space stations. The main ship-to-ship weapons of the Yashima-class remains the typical 460mm railguns as seen on other battleship classes, mounting 18 triple-cannoned turrets. All of the main guns are aimed with the aid of the shipboard AI systems, of which three are installed.

Atypically for such a large ship, the Yashima-class does not mount a large amount of heavy beam lasers, with only eight Type-14 Grand Lance ultra-heavy beam lasers equipped, with four on the port side and four on the starboard side. This is due to the Yashima-class' design philosophy of moving close to enemy fleets before engaging with all of its firepower, with the long-range lances' long-range bombardment role also replaced by the 800 millimetre railguns. Despite this, the Type-14 Grand Lance is one of the most powerful models of beam laser mounted on a mobile vessel. Twelve Type-68 triple torpedo tubes are also present on the fore and aft of the ship for long-range combat and battle-opening salvos.

For closer-range combat, to complement the railgun systems and combat close-range craft, 84 quadruple-cell missile launchers are present throughout the hull at strategic locations to provide all-round offensive capability.

#### Secondary armament

In addition to its main weaponry, each Yashima-class battleship is also equipped with 40 turrets consisting of 20mm laser cannons in twin mounts for close-range and anti-fighter purposes. Complementing these are 24 quadruple-mounted Beam Guns for further anti-fighter purposes.

Spread across the hull are 30 of the ubiquitous Yamabushi CIWS systems, for anti-missile and anti-fighter purposes. The Yashima-class also has four mine dispensers in the aft.

### Armour

Designed to engage multiple enemy warships simultaneously, the Yashima-class is fitted with heavy armour plating comprised of the typical Yamataian armour blend of external Titanium-Haruhium plating with interlaced Yukitate Crystal Lattice for protection against energy weapons, a honeycomb mesh structure for protection against blunt-force impacts, followed by an internal layer of Titanium-3 plating. At its thickest point the armour is over five meters thick, though it generally has a thickness of around 200 centimetres.
