The Amatsuotome Expeditionary Command Cruiser was designed in YE 34 to replace older flagship designs with a powerful ship that was capable of tending to its fleet without the need of a starbase. It was designed and built as a joint project between Origin Industries and Ketsurui Fleet Yards.
The Amatsuotome was originally conceived as a replacement for the Takumi-class Expeditionary Command Cruiser, but it soon became more than a simple replacement. Drawing on resources from both KFY and Origin, the ship quickly evolved from a simple command ship to what was essentially a miniature starbase. The addition of an Ayame-like docking ring to what was turning into another forgettable battleship suddenly made the idea much more useable and capable in its role as a fleet's command vessel.
The key, and most distinguishing feature of the Amatsuotome-class, is the large, circular docking ring around the rear third of the ship, which gives it the ability to tend and support a fleet without the need for a starbase in most situations.
The Amatsuotome looks like a pillar laid on its side, with a disc stuffed through the middle of it horizontally. Near the back is a large cluster of systems, including the four main thrusters. Attached to these thrusters via a system of supports and elevators is a vast docking ring which has 8 ship hangars and 8 large docking structures. The sides of the ship are covered in gimbal-mounted turrets, and there are numerous spikes and fins poking off the ship at different points.
The Amatsuotome-class is based upon an older design that had never even made it to the prototype stage, due to Origin's shift of focus to smaller ship classes. However, in YE 34, the Star Army Fifth Fleet approached Origin with several proposals, ranging from simple weapons all the way up to a new ship class. The old design was dusted off, and brought back into the fold, where some of KFY's engineers suggested adding on to the design, and rearranging the layout. These suggestions were taken into consideration and eventually added in, creating what would become the Amatsuotome-class.
See Damage Rating (Version 2) for an explanation of the damage system.
Because of the size and volume of the Amatsuotome, it is very luxurious inside. Intended as a fleet's flagship, it contains quarters for both the Admiral and the Captain
The Main cargo area of the Amatsuotome is located in the belly of the ship, accessed on either side by the massive forward-facing hangar openings beneath the central disc. The Cargo bay is 350x800x100 meters
The Amatsuotome has several kinds of crew cabins, for enlisted, officers, and, essential for ground operations, barracks for Infantry. Decks four and five are entirely devoted to housing infantry, while Deck two contains a ring of crew cabins around the recreation areas. Spread about each of the crew decks are a number of accommodations, including dining areas.
The Observation deck is, essentially, three things. A park, a mall, and an observation deck, being covered with a 100m x 50m transparent Zesuaium bubble. It is part of the recreation available for the Amatsuotome, though naturally it is evacuated in the case of a battle.
The Amatsuotome's engineering main space is sandwiched between the cargo bay and the massive hydrogen tanks which power the ship. This main space has passageways leading from it to each of the four enormous fusion power-plants, to all the weapons systems, and to the computer cores. There are also a number of damage control stations spread about the ship.
The Amatsuotome has a hybrid of KFY and Origin-style maintenance conduits; the conduits are the larger, 1m square Origin-style conduits, which have gratings covering the systems to keep them in place and protect the engineers, but they also, like the KFY-style tubular conduits, now have padded floors and ceilings, with bulkheads every 10 meters, and strapping to aide movement in low-gravity conditions.
The Amatsuotome's main medical center is a Star Army Standard Hospital Center, located centrally in the ship. Supplementing this hospital center are ten Sakura-type Medical laboratories, increasing the capacity of the ship's medical capabilities, and shortening the distance between an injury and its treatment.
A system of small tram cars which run on lines traversing either side of each of the inhabited decks, except for the Observation deck.
There are three types of Hangar bays on the Amatsuotome; Standard hangars, housed in the main hull, and support hangars, housed in the docking ring. Both of these types hangars can internally micromanage the level of gravity, allowing easier lifting of heavy objects, or allowing people to comfortably work in normal gravity. They all also contain all the necessary tools and equipment to repair and maintain starships. On top of this, there are numerous shuttle bays.
The Amatsuotome has two construction bays, which are capable of building starships. 600 meters long, and 300 meters at their widest point, these semi-circle bays can create most ships of the Plumeria-class and smaller. The top of the bay is normally covered, but can retract to allow constructed ships to deploy. Only one type of ship may be built at a time.
The Amatsuotome's docking ring contains eight docking points, allowing for larger ships, such as the Sharie-class, to dock with the Amatsuotome, for the transfer of supplies and personnel. These tunnels can be extended to fit different ship classes, and the gravity within can be controlled in order to easily facilitate the passage of personnel and goods between the craft.
The Amatsuotome's superstructure is composed of three main parts. The innermost part is a fine Zesuaium latticework, providing the backbone for the ship, creating a rigid structure onto which everything else is mounted. The middle layer is composed of ten meters of Yamataium, making up the bulk of the ship's physical defenses. Encasing the entire ship is a third layer of armoring, made from five meters of Endurium, which adds another layer of defense to keep the internals of the ship safe.
The Amatsuotome is an odd ship in that it has two computer cores, of different design and manufacture, which work in unison (usually) and account for one another's weaknesses, making an overall more effective system.
The Amatsuotome has a Matter Collection System, allowing it to take in resources from space, usually by flying through Nebulae. As opposed to simply using the four relatively small opening located at the front of each of the massive fusion engines, the Amatsuotome's MCS can project larger virtual 'scoops' using the shield system, to increase the area from which the ship can collect matter.
The ship has three methods of Propulsion, for various conditions.
The Amatsuotome has two main types of power generation: Aether, and Fusion.
The Amatsuotome carries four kinds of shielding. The shields generators are buried in the hull of the ship, with four large shield deflectors built onto the hull, arranged around the middle of the ship.
Electromagnetic shields: The shield creates a bubble which encompasses the entire ship. Combined threshold 4
Gravitic shielding: This creates a shield bubble that encompasses the entire ship. Combined threshold 4
Navigational shielding protects the ship against navigational hazards, and allows the ship to run with a smaller sensor signature. This shielding system, however, does not help much against weapons. Threshold 1 (non-stacking)
The Amatsuotome's cavernous hangars in the main hull allow for even full-sized starships to dock internally. While it is capable of being reconfigured, the standard configuration of the Amatsuotome has docking spaces for 20 Courier freighters, ten in either of the two hangars.
The Amatsuotome can support about 1000 shuttles at any given time. Typically they are Kuma T8 shuttles.
The Amatsuotome has two main fighter types on board, one for space combat, and one for general purpose and defensive work.
The Amatsuotome carries two types of Power Armor, the ubiquitous Mindy for space operations, and the sturdier Daisy for ground operations. As most space-borne combat is handled by fighters, the number of Mindy armors is much smaller than the number of Daisy Armors.
