As a part of the Rikugun’s attempts to become more mobile, studies into developing an assault carrier to replace the Kagai-Class Assault Ship was launched. The Kagai, which began its life as a cruiser, didn't have the internal lay out to move more than a Rikugun century and their equipment. This had the potential to cause unit cohesion issues as the movement of a single battalion would require personnel to be spread across several ships. Rikugun leadership felt that this was an inefficient use of resources.

After the Yugumo Corporation was contracted to design the Teisatsu-class Special Operations Support Transport, they were approached by the Star Army Rikugun to build them an assault carrier capable of moving an entire Regiment along the same design philosophy. Functionally, the Rikugun Regimental Assault Carrier is a scaled up and less modular version of the SOST.

In 44.8 Mizumitsu Benji Taisho Rikugun Chief of Staff designated the Rikugun Regimental Assault Carrier as the Sigrún-class “Rikugun” Regimental Assault Carrier.

Forgoing the Aether Shock Array found on most larger Star Army of Yamatai vessels, and opting for an overall taller frame and more compact interior, the RRAC manages to maintain the Star Army’s customary swept look while managing a much more space efficient deck plan. Sacrificing the internal comfort of a similarly sized vessel such as a Fuji-class Expeditionary Gunship, the ship can transport and support an entire Rikugun Regiment along with its associated vehicles and equipment. The resulting use of vertical space results in a taller and bulkier silhouette than Star Army vessels of a similar length. The RRAC is down right cramped compared to most Star Army vessels. The RRAC is not a craft designed for long range patrols or exploration missions. Instead when not involved in exercises, operations, or on standby, these ships remain docked with space stations or large command ships such as a Tanya-Class Expeditionary Heavy Cruiser or an Izanagi-Class Dreadnought.

Like with its sister design, the SOST, the aft portion of the RRAC is given over to cargo and hangar bays. There is a command spire at midship and crew living quarters and training facilities are located towards the bow.

While the ship is intended to be versatile these are the primary mission profiles.

1. Contested troop landings
2. Regimental troop transport
3. Command and control plus intelligence, surveillance, target acquisition, and reconnaissance (C2ISTAR)
4. Fire support for planetary forces
5. Rapid response
6. Field resupply
7. Humanitarian aid

(fix up table and put it here)

Yugumo standard items add details and customize.

• Escape pods, emergency lockers, and emergency sound-powered telephones are present in abundance on every deck. Other security features are present where appropriate as well.
• Other safety equipment such as panic buttons, intercoms, [[items:equipment:fire_extinguishers]], AEDs, eyewash stations, and safety showers are readily accessible on every deck.
• Public toilets and water fountains, vending machines, and housekeeping closets are ubiquitous and conveniently accessible on every deck.
• Standard Star Army Zero-Gravity Passageways are the main method of vertical movement in the crew compartments. There are freight elevators and a personnel lift in the Aft Cargo Area.
• Multilingual signage, both physical and volumetric, are conspicuously and frequently posted, clearly marking compartments, features, and directions at every intersection. There are information kiosks with interactive displays as well. A personalized guide may projected on the floor to help individuals find their way, and also have alert and emergency modes. Sectors oh the ship have color-coded recognition-aid features
• Magazines are fully automated and only accessible via maintenance conduits and their loading ports, irrespective of what deck they are on, as are the weapons systems themselves.
• Maintenance conduits crisscross every deck, and between decks, parallel to the main passageways. In populated areas they have inconspicuous entrances.
• Walls, ceiling, and floor have an anti-spalling coating.

Some ideas for compartments below…

Ships officers use cabins based off of the MFY Type 30 Standard Officer's Cabin that are modified to hold a pair of twin beds. There are eight such cabins allowing room for a standard compliment of officers and leaving room for guest officers. Enlisted personnel sleep in the twenty-two standard MFY Type 30 Standard Enlisted Bunkroom. The Captain's and XO's quarters are unmodified Type 30 Standard Officer's Cabins. As per Star Army regulations, the crew cabins are modified with Military variant Type 40 Star Army Bunk Beds.

Because of the cramped quarters aboard the RRAC, while there are two small MFY Type 30 style dining halls, both are mixed dining. Officers do tend to congregate to one side or other, but there isn't space to make an entirely separate officer's mess beyond the Wardroom. By maintaining two small dining halls instead of a single large one, one facility can be closed and converted into a recreation room, briefing room, or theater while the other remains open for diners.

Food prep and stuff. (determining if there should be a public use one)

Visiting Flag officers, diplomats, other VIPs. Visiting officers of field grade or lower tend to bunk in the crew quarters if space is available.

Known to the crew as “the land of comfy couches,” the General Recreation Room contains a large number of the coveted couches, general gaming tables, and electronic entertainment and is an excellent place for crew to mingle and unwind between shifts. The Recreation Room is the best place on the ship to find a Catacombs & Creatures group that meets regularly.

Cramped, even for the officers, the Rikugun Quarters are treated more as temporary housing than the more permanent and elaborate quarters most ship's crew enjoy. The quarters are a warren of narrow hallways connecting barracks, bunk rooms, heads, laundry facilities, and common rooms. Rikugun officers are bunked two to a room in quarters resembling MFY Type 30 Standard Enlisted Bunkroom⁶⁾. There are 135 such cabins. The Regiment Commander and their XO are allowed small single occupant cabins. Enlisted troops bunk in barracks in the Star Army Half-Century Barracks (Plumeria Type) configuration. There are 44 such barracks, allowing room for every soldier and potential spillover. These extra bunks are often occupied by specialists on temporary assignment such as Star Army Special Operations elements. The barracks include an extended version of the MFY Type 30 Standard Enlisted Bath House and two MFY Type 30 Standard Laundry Facility at either end of the enlisted section and a single one in the officer's quarters.

Volumetrics room, fitness center, small briefing rooms

Ships officers often dine in the MFY Type 30 Standard Wardroom. Officers from the attached Rikugun Regiment can choose to use the Wardroom, but due to the small size, generally only field grade officers dine there.

The RRAC is commanded from a Star Army specific version of the Misha-class Bridge SAoY Update located in a conning tower. In the exterior hallway, facing the bridge, there is a port side door to a conference room and a starboard door leading to a Combat Information Center (CIC) in the model of the Ascendancy-class Flagship’s Fleet Information Center. The CIC provides advanced command and control for air and ground assets and communication and coordination with other fleet assets allowing the bridge to focus on ship’s operations. SPINE compatible chairs (need to elaborate)

MEGAMI and KAIMON-Gate cores and cryo cooling systems.

Taking influence from the MFY Type 30 Warship Engineering, the engineering bay is somewhat oversized for the ship's size. This is to account for massive aether generator powering the ship's powerful sensor, comms, and E-War suites, and allowing its Yumeoibito Hyperspace Fold Drive to charge at record times.

Maintenance access S

(4×6 cargo)

The primarily for cargo bays, mech and power armor bays, and houses a workshop and armory. It has a deck has a roof clearance of 12 meters Apart from a lower ceiling clearance, all three bays are heavily based off of the Yugumo Standard Cargo Bay. While this bay is primarily a warehouse for mission equipment, there are spaces for overflow from crew storage. This level also includes the storage for Mecha and Power Armor.

A portion of the storage bay is armored and grounded.⁷⁾ Only accessible by armorers and stores missiles and bombs and the like and keeps them safe from tamper or accidental detonation. Limits the damage such a detonation can have to the rest of the craft.

Four freight elevators⁸⁾ freight elevators are positioned towards the fore and aft of the cargo decks. They facilitate the rapid movement of troops, vehicles, and equipment between floors. Yellow safety lights flash when the elevator is in use, and the floor around the elevator shaft is marked in black and yellow warning stripes.⁹⁾ There are also two smaller personnel lifts near the airlock.

The Garage and Surface Vehicle bay is split into two 5400 square meter vehicle bays, each 6 meters tall. The front and rear of this deck have airlock/boarding rams that allow vehicles to roll directly on and off the ship into the upper bay. Ramps, stairs, and freight elevators connect this these levels to the main cargo level and the Hangar and Launch Bay hangar.

The top deck is a 3600 square meter small craft hangar that leads into a launch bay Ke-A1-R4200 Vehicle Subspace Deployment System.

Like many of Yugumo’s modern designs, the RRAC utilizes Yamataium ¹⁰⁾ for the hull structure. All windows and viewports utilize Transparent Durandium, and most have a retractable armored exterior covering for opacity against beam weaponry.

Like other Star Army crafts of its size, the RRAC uses a MEGAMI as its primary ship’s computer. This system is utilized for primary computing, sensing, and communications. By allocating secondary tasks to the KAIMON-Gate suite, a large amount of extra processing power is cleared up leading to even faster problem solving and target identification. The KAIMON system isn’t without its own tricks. The Sorakagami Aerospace Operations Suite gives Tower Officers, Air Traffic Controllers, and Mission Operators advanced Battlespace Communications, Command, and Control capabilities. This helps the RRAC carry out its vital duty of gathering raw data and processing it into a usable intelligence product in order to coordinate between its organic surface and aerospace assets and with wider fleet assets. The Umikagami Subsurface Operations Suite further expands the RRAC’s operational capabilities. As with the sensor suite on the recent Yugumo Tanya-Class Expeditionary Heavy Cruiser the RRAC's impressive sensor suite includes a Mineral Scanner and a SachiTech Tech-Scanner available to the science officer, expanding the types of information available to ground assets.

Both the MEGAMI and KAIMON suites are stored in armored rooms kept below −153 °C with the use of pulse tube refrigerators. The temperature can be temporarily brought up to livable temperatures allowing maintenance technicians to service them.

The RRAC also mounts the Star Army Electronic Warfare Suite, Type 44 a mil-spec variant of the Yugumo (ELECTRA) E-War suite.

The Tanya-Class Expeditionary Heavy Cruiser is equipped with yu_standard_emergency_systems. It has its own fire suppression system and Forcefield-Nested Isolation Doors, and Yugumo Standard Damage Control Alcoves to assist with the repair of damage to the ship in the event an emergency occurs. All windows and viewports are Transparent Durandium, with retractable armored blast shields to provide further protection or opacity against beam weaponry.

In the event of a catastrophic failure or impending doom, the ship has 3200 "Ikigai" Escape Pods. ¹²⁾

There are more than enough Yugumo Standard Damage Control Alcoves, Yugumo Standard First Aid Lockers, Yugumo Standard Armory, and Yugumo Standard Survival Lockers easily accessible at key points throughout the ship, all fully-stocked, for any emergency.

Star Army Standard Life Support Systems (Primary) Yugumo Standard Life Support Systems (Backup)

Not ones to unnecessarily reinvent the wheel, the RRAC’s design team utilized lessons learned from the Star Army of Yamatai 1B variant of the Tanya-Class Expeditionary Heavy Cruiser when designing propulsion systems. The RRAC's primary sublight propulsion comes in the form of a pair of Hoshi III Series Multi-stage Turbo Plasma Drives located on the ends of its wing assemblies. Sublight performance for this craft usually can withstand 0.375c.

(Ion thrusters) and the Plasma Projection System are used for attitude adjustments and docking among other precision sublight maneuvers .

For FTL travel, the RRAC utilizes a Yumeoibito - Max Hyperspace Fold Drive capable of speeds of 394,470c (0.75 ly/m) and their Integrated CFS Array for secondary FTL propulsion maxing out at 18,750c

Umikagami Subsurface operations suite enables the use of Magnetohydrodynamic Propulsion with the Hoshi III Series Multi-stage Turbo Plasma Drives for underwater propulsion.
