Tengumo-Class Space Station

The Tengumo-Class Space Station is a mobile space station developed by the Yugumo Corporation in late YE 45 with the first station set to come online in late YE 45 with others following in YE 46.

Tengumo 天雲 is a Yamataigo (邪馬台語) word meaning “Imperial/Celestial Cloud”.

History and Background

Until YE 45 the Yugumo Corporation had not developed their own class of mobile space station or shipyard. They had relied on the Geshrinari Shipyards Ge-H1-7A - Kōdaina Minato-Class Orbital Installation of which Port Jiyuu and its modified, older industrial station Port Siren(Kodoku-Class Mining and Processing Facility). Both stations were modified for mobile use and taken with the Colonization Initiative Alliance fleet to the Kosuke Sector1)2)3). Unwilling to commit to the daunting task or price tag of having two Ge-H1-7A - Kōdaina Minato-Class Orbital Installation constructed to replace them, the Yugumo Corporation decided to finally construct their own class of mobile space station that was customized to their needs at a more reasonable cost and size.

  Yugumo Fleetworks brought together their design team and came up with the concept for the new Tengumo-Class Space Station. The primary design schematics were approved in YE 45.7, with the first of the planned stations set to come online sometime in the early part of YE 46. A second version of the station was planned to replace the Kodoku-Class Mining and Processing Facility, but it was set as a lower priority as that the purchased Dragon-class Mobile Refinery vessels could handle refinery needs for the corporation until the design could be perfected.

In reality, parts of the design for the Tengumo-Class began long before the initialization of the project, as the production of their own dedicated shipyards and space stations had been circulating since the Yugumo Fleetworks had come together in YE 43, it was just there had not been a call for their development from management until this project started. The design team came forward with multiple suggestions that were updated plans from what had been a wishlist created for the day the company was in need.

Kumo no Kagayaki Station will be the first of these stations to be built. It will be positioned in the Jiyuu System.

Description and Design Goals

The Tengumo-Class Space Station is a mobile space station designed to serve as a civilian commercial hub, residential “city in space” and port-of-call in key systems within the Yamatai Star Empire, in particular, but not limited to the Motoyoshi Colonial Sector and future development in the Kosuke Sector4). The decision for the mobile design was influenced by not only the company's need to be able to move the stations between locations but also to utilize them as part of the overall evacuation plans for the systems they would be built in.

Design Goals and Mission Specialization

The Tengumo-Class Space Station was designed to meet the following design specifications set by the management of the Yugumo Corporation:

  1. To serve as a commercial hub for imports and exports in a system.
  2. To accommodate civilian populations serving as a city in space.
  3. To have functional shipyards for the production of Yugumo Fleetworks or the customer.
  4. With the start of the Third Mishhuvurthyar War, serve as part of the evacuation structure for systems in the event of invasion. 5)

Environmental controls and forcefields maintain a controlled atmosphere within the bay, facilitating seamless operations without the need for decompression.


The Factory on the Space Station is the largest built by the company. Within these areas, skilled Engine Rating Crew and Engine Officers collaborate with advanced machinery like KAIMONand Yugumo Fabrication Systems to create a diverse range of items, from uniforms and drones to power armor. These facilities boast stringent quality control measures, robust security protocols, and precise environmental controls to ensure safety, precision, and efficiency throughout the manufacturing process. Materials are managed efficiently through nanofabrication systems, material recyclers, and resource processors, reducing reliance on external supplies and waste production. Located deep within the station's hull and connected to the Cargo Bays for efficient material movement.

Cargo Bays

The Cargo Bays were inspired by the success of the Shuryoku-Class Super Freighter, this versatile cargo bay serves as the logistical hub of a starship or space station, facilitating the storage, transportation, and access to a diverse array of goods, equipment, and supplies crucial for missions, trade, exploration, and survival. Positioned typically in the central or lower section of the vessel for stability, the cargo bay comes in various sizes to accommodate the starship's type and purpose, with the capacity to store Standard Starship Cargo Containers efficiently using tracks, cranes, and robotic arms. Entry to the cargo bay is provided through large, Forcefield-Nested Isolation Doors, ensuring ship integrity during emergencies. Durandium Alloy-reinforced walls and modular securing mechanisms protect cargo during space travel, while Graviton Generated Forcefields maintain atmospheric and environmental conditions inside the container holds. Adjustable laser diode lighting enhances visibility, while environmental controls cater to cargo-specific needs. A range of cargo-handling equipment, including KAIMON/Ascendant Carrier, anti-gravity lifters, cargo cranes, and transport sleds, assists crew members in cargo handling, with software systems like KAIMON managing manifests and inventory for efficient tracking and retrieval.

Production Bays

The two massive extensions of the Tengumo-Class Station's main structure are the station's production bays. They are large enough to support the construction space for up to eight Tanya-Class Expeditionary Heavy Cruiser each at a time. They are connected to the station's Factories to ensure the adequate movement of materials needed for ship construction to the bays. The bays include shipyard supervisor stations, KAIMON controlled robotic arms, cranes, and other machinery, and are well stocked with construction mecha.

Docking Structures

The station has six extendable docking arms designed to accommodate up to forty Misha-Class Explorer or Yūgure-class Merchant Destroyer along their sides. The larger docking connection at the end of the arms is designed for Tanya-Class Expeditionary Heavy Cruiser or larger vessels They were designed in expectation of the new Misha 2 which should be released sometime in YE 46.

External Construction Frames

Shipyard Modules/External Construction FrameDue to the restrictions of internal construction bays, the station's production capabilities are increased by shipyard modules/external construction modules. These units have their own dedicated shipyard management offices, and Hoshi II Series Turbo Plasma Drives to assist them as they are positioned to construct starships externally from the station's main body.
