Takumi-class Expeditionary Command Cruiser

The second vessel designed by the Taisho Ketsurui-Motoyoshi Katsuko, Commander of the Star Army’s Fifth Expeditionary Fleet and the KFY Designers posted at Taiie no Iori and then later at Akina no Iori. This state-of-the-art command cruiser was intended to expand the horizons of SARA’s colonization and exploration initiatives by providing a capital ship capable of executing extreme long range missions along with the newer Hummingbird-class Colony Ship, also designed by Taisho Motoyoshi.

Design Goals

The Takumi meets the following design considerations, derived from Star Army Research Administration’s response to the initial design proposal:

  • A capital ship of the 'Command Cruiser' classification capable of performing independent operations with limited need for resupply or fleet resources.
  • A vessel identified as a ‘long-range force protection weapon’ specifically with colonization fleets in mind.
  • A vessel equipped with state-of-the-art laboratory facilities, capable of handling a large volume of samples, specimens and equipment.
  • Large production bays for the production of mission specific equipment, weapons and other products.

History and Namesake

The ‘Takumi’ Name, translated to ‘Peace and Calm’ was chosen to promote the strong shift toward a vessel designed more for exploration. Not to ignore however, that the Takumi Class ECC is more than well equipped with the latest and some of the most powerful weaponry available to the Star Army of Yamatai. Vessels constructed of the Takumi line are to be given names relating to nature. (Moons, planets, forests, rivers, and other things in the natural world).

Production of the Takumi ECC began in YE 29, with the prototype, YSS Takumi being completed ahead of schedule at Taiie no Iori, Headquarters of the Fifth Expeditionary Fleet. However, a set back was encountered when the Iori was destroyed and production had to be moved to KFY’s Luna Bianca Lunar Shipyards, and Yamatai Shipyards. Thankfully the prototype was engaged in a field testing in the Katsuko Nebula and escaped destruction.

The YSS Yugumo, the second ship of the Takumi line was finished being built in YE 29. The YSS Yugumo would become a key ship in the Fifth Expeditionary Fleet on its exploration mission, to venture far beyond the current sphere of the empire’s influence.

In late YE 30, the Takumi received an upgrade to its computer systems (from WIES to MEGAMI).

Notable Internal Features

Main Bridge


Three aft sections of decks twenty two, twenty three and twenty four are devoted to main engineering. Engineering houses the primary Aether generator power plant, hyperspace fold drive, and other major systems. It is also the primary junction point of maintenance conduits that lead to other system access points around the ship and can serve as an auxiliary method of moving thru the vessel. The chief engineer’s office is located off the main control room on deck twenty three.

Maintenance tunnels have several alcoves for production of NH-12 Nekovalkyrja Sprites for damage control and intruder suppression. The tunnels are large enough to accommodate most Star Army Power Armors.

Two secondary engineering monitoring rooms also are located in the forward bow, here the secondary quantum power plants, and backup controls can be accessed in the event that main engineering is compromised in combat or other high alert situations.

Auxiliary Bridge

In the event that the main bridge is compromised or destroyed there is an auxiliary control room located on deck thirty in the most central area of the ship. The auxiliary bridge is heavily armored, its interior sections are lined with Yamataium plates and it has its own quantum power plant, access to the ACS, its own Hemosynthetic Conduit System network and can be sealed off from the rest of the ship.

Laboratory Complex I

The Takumi boasts the largest scientific laboratory of any ship in the fleet. With the ability to accommodate over two hundred science personnel. There are eight decks in the central forward section of the ship devoted to Biology/Xenobiology, Chemistry, Organic Chemistry, and other labs as well as two storage facilities for containment of specimens large and small and of various risk levels. The labs all meet Star Army Research Administration regulations for bio-containment, safety and research integrity.

Laboratory Complex II

The second section of the laboratory complex is an additional two deck sections beneath Laboratory Complex I. Equipped with mission variable laboratory spaces, stellar cartography, and houses the ship’s Medical Bay. The ship’s medical bay serves the needs of the crew with a spacious infirmary, examination alcoves, and operating rooms. Medical Bay is also the central junction for the ship’s HSCS systems and is where body synthesis, mental backups and torture of prisoners is generally conducted.

Galaxy Arboretum

The Galaxy Arboretum is an artificially maintained Yamatai environment. This area of the ship simulates the experience of being on Yamatai, everything from crystal rippling ponds filled with fancy fish to towering fruit trees and a variable climate control system to simulate weather and maintain this carefully planned environment. Benches, fountains and walking paths make for a great way to relax during those off duty hours. This section of the ship was recommended by Star Army Research Administration for maintaining a good mental state in crew members during extremely long voyages.

Enlisted Barracks

Enlisted accommodations are small cabins built to accommodate four to six crew members. Bunks are inset into the walls allowing for the central cabin to be open living space, large enough to fit a few chairs and a table. Unoccupied bunks can be utilized for additional storage. Each crew member is allocated:

  • A bunk, with standard issued sheets, thermal blanket and pillow.
  • Two under bunk storage drawers
  • One small storage locker (inset into the headboard)
  • An allotment of space in the storage closet for additional clothing and belongings

Per two enlisted cabins there is one shower room, showers are communal showers with enough room to accommodate eight to twelve NH-29’s and maybe a few toys or extra shower friends.

Enlisted Common Rooms

Large community areas devoted to the rest and relaxation of crew members when they are off duty. Most common rooms have several comfortable couches, chairs and other decorative fixtures. A small beverage and Food bar ran by the ship’s hospitality crew is located in these areas to reduce the number of crew members using the dining hall for minor demands, as well as to serve alcohol during social gatherings.

Media Rooms

A place for crew members to unwind and socialize. The room is equipped with video games, virtual reality and a small area devoted to the viewing of films or other entertainment.

Enlisted Dining Hall

A large cafeteria and auditorium equipped with a state-of-the-art kitchen facility. The Dining hall often doubles as a place for large gatherings that the common rooms cannot contain like theatre productions, talent shows, and other morale boosting events.

Officer Quarters

Intended for one or two officers, these quarters are spacious and nicely decorated. Officers are given a small workstation/desk area, a large walk-in closet, their own head and larger beds. The quarters are carpeted and comfortable with the extended voyage in mind.

Officer’s Dining Hall

A finely decorated dining area with decorative carpets, tapestries and the occasional chandelier set an ambiance of elegance for the enjoyment of those charged with the running of the ship. The Food served is often gourmet, and a small stage is located in the forward area of the room for the occasional musical production.

Cargo Bay & Storage Section

Located in the aft most ventral section of the ship underneath the armor bays the ship’s main cargo bay and warehouse is a fully automated storage and receiving center for the goods required for missions, equipment and overflow for storage for the personal effects of the crew. The cargo facility is managed by the computer, small cranes, haulers, and transports move materials into the appropriate storage areas. The cargo bay is equipped with an exterior docking mount specifically designed to accommodate docking with the new Odori Class Freighter.

Production Bay

Located forward of the Cargo Bay and Storage Section is a spacious production facility inspired by the fabrication rooms on the newer class of light cruiser. The production bay allows for the ship’s nodal system to manufacture equipment, weapons, and other needed materials. Finished products are then forwarded via a series of conveyors, automated carts and lifts to storage in the cargo area or weapons hold of the ship.

Multi-purpose Rapid Launch Bays

The launch bay is located above the cargo bay and storage facility. The bay is the entire width of the aft section, and is the height of three average deck sections, however from the exterior it appear there are two distinct bays. Two bay doors open up from the stern of the vessel, and a single door both the port and starboard side. The combined bay serves for the launch of shuttles and armors. The floor is a glossy, polished black and the walls are made of the typical gray paneling found in most Star Army ships.

Maintenance alcoves line the forward most section of the bays, as well as pilot locker storage and weapon holds for armor weaponry and accessories. In the event of an emergency, blast shutters and force fields can seal the armor bay off from the rest of the ship.


The lifts provide quick access from deck to the deck. Lift can also be used to travel to other ships when vessels link together (most Star Army ships have standard gauges of lift systems, allowing lift cars to move from ship to ship).


Takumi Space Frame & Integrated Hull Systems

Primary Space frame

The Takumi’s primary space frame is constructed primarily of Zesuaium truss frames interlocked together. These major trusses are arranged in higher concentration around the sections of the vessel that are most likely to become stressed like around the CDD nacelles, auxiliary engines and to provide additional strength to areas such as armor bays, the main bridge and around major weapon mounts. Smaller Zesuaium trusses that form the interior frame of the vessel provide internal support for decks and interior sections.

Force field generators are arranged at major truss junctions to provide additional strength, and protect these junctions from anti-matter hits in the event the major space frame becomes exposed or compromised in a battle. Of course the force field generators are small and can only absorb a limited amount of energy before becoming useless but this serves effort to provide strength to the space frame.

Secondary Space frame

Secondary framework is nested within the primary space frame to provide additional support and provide support for ships systems. The secondary frame is composed primarily of small Yamataium trusses and rods lined with Yarvex meshing to provide shielding to interior structures.

Armored Hull Plating

The primary substrate of the hull plating is Zesuaium coated 0.60m thick Yamataium plates. Interior sections of the vessel are provided shielding by layering of Yarvex meshing across the secondary framework structure.

  • Zesuaium-S: Zesuaium is a nonporous gray substance which does not conduct any form of electromagnetic radiation, including heat and electricity. It neither bends nor breaks, but will remain in a solid piece. The fabrication of Zesuaium takes place factory starships, where a certain substance is molded in the shape desired, and then is transmuted into the fixed Zesuaium form. The properties of Zesuaium are related to time energy. In the Takumi ECC, Zesuaium is interlaced with Yamataium in the hull plating.
  • Yamataium-S: Because Zesuaium armor is nearly impossible to repair, the ship's plating is primarily composed of Yamataium-S, a SARA-created artificial metalloid with self-healing molecular bonds. Under the guidance of the HSCS-3, the Yamataium can patch holes as needed in a matter of days. Yamataium-S is also made to interact efficiently with the repair systems and bond with Zesuaium-S.
  • Yarvex: A highly advanced, virtually impenetrable gluon mesh, first used by Ketsurui Fleet Yards in the Ke-M3 Series "Kylie" Anti-Armor Power Armor power armor. Particles that make up protons (quarks and gluons) the gluons and quarks are strung together in a long chain using an alteration of Yang-Mills Theory. This permanently binds the quarks together so they may never be pulled apart. The resulting cloth like substance is impervious to penetration, although it does nothing to stop kinetic energy. All interior passageways and rooms are surrounded by Yarvex sheeting.

Computer System

The Takumi uses the MEGAMI and a Type 31 Electronic Warfare Suite.

Combined Field System

The Takumi has an excellent combined field system. In effect, the CFS sustains a small “pocket universe” around the vessel by nesting electrogravitic and electrostatic fields. Gravity and time outside the shield bubble do not affect the objects inside, and objects inside the bubble are protected from both solid and beam weaponry, because the projectiles or beams pass through the curved space and around the ship. The combined field serves a number of purposes, including propulsion, defense, weaponry, and stealth; for this reason, it is almost always on. The CFS can also be used to generate waves and pulses, which can be used to detect hidden ships and objects when used in combination with the sensors.

Interdiction Field

The ship is capable of projecting a powerful artificial gravitic field that disrupts the operations of FTL drives of all types in a specific area of effect (minimal effective AOE is a 1,000 meter cubic area; maximum AOE is 1 AU cubic area). This is useful in preventing enemy vessels from escaping from battle. The interdiction field also has a secondary mode that can defeat the interdiction efforts of enemy forces in a localized area roughly half the size of its normal operation.


The ship propels itself at speeds many times the speed of light by generating continuum distortions in the CFS and nesting them to create asymmetric peristaltic fields. The normal CDD speeds are augmented by working with the forward deflector (located on the underside of the ship). This allows the ship to travel thousands of times the speed of light. This gives Star Army ships the advantage of attacking at FTL speeds. The Takumi uses a combined distortion drive capable of generating small wormholes, navigating the quantum slipstream, creating hyperspace fold points, and acting as sublight propulsion. Distortion-based systems allow the ship to stop or move nearly instantly because the ship has not “moved.”

Primary Defense

The shields are automatically modulated and phased by the ships computer system. While all frequencies, planes, and dimensions are theoretically covered by the shield, the modulation enables extra power to be routed to the bands, planes, and frequencies in which enemy weapons operate, decreasing the possibility of a shield overload and rendering enemy weapons largely useless. The CFS also protects the ship from collisions during high-speed space flight and can be used to facilitate ramming other vessels. As the ship's defense against weapons and high-speed impacts such as meteors in space and debris from destroyed starships, the shield is extremely powerful. The CFS can protect against up to 22 YottaWatts worth of damage per 1 square meter area in either kinetic or energy form, making the ship VERY difficult to damage, even with most main guns.

Outer Defense

The shield system is bordered (at a several kilometers out from the ship) with an intense scalar field which serves to dud electronics of incoming missiles and mecha, as well as detonating explosives, ablative armor, and overloading the nervous systems of pilots. This feature is disabled during normal operations, and (usually) enabled in combat.


The ship can also be rendered invisible to scalar radar, aetheric-energy sensors, other forms of detection by using the shield bubble to keep the ship in its own alternate plane of existence. It can also use its scalar fields to simulate that photons and other sensory forms pass through the “empty space” and thus its presence is hidden. When the ship is fully it its bubble plane, it may only use its RDD sensor to monitor normal space.

Auxiliary Engines

The ship has three ion impulse engines for use if the CFS system is damaged or destroyed.

Hyperspace Fold Drive

A FTL propulsion drive which pushes a vessel into a dimension adjacent to our own dimension but where distances are far smaller.

Emergency Systems

Escape Pods

The Takumi uses Ke-S3-X2900 escape pods.

Hemosynthetic Conduit Systems

This network, consisting of blood-filled tubes, runs throughout the ship carrying femtomechanical purpose-oriented molecules (constructed at the level of elementary particles) that are tied to the ship's life support and computer system. At access points, the bloodstream can hemosynthesize objects, including Food and Water packages, as well as dissolve objects. A secondary internal network (HSCS-2) recycles and dissolves waste, and a third, independent system (HSCS-3) carries femtomachines through various parts of the ship where repairs are needed, to control damage automatically, even during combat.

The HSCS system fluid can be differentiated by color. The HSCS-1 system is bright red, HSCS-2 is brown, and HSCS-3 is gray. While the HSCS-1 and HSCS-3 fluids are harmless to Nekos, the HSCS-2 waste liquid is extremely dangerous to organics (it dissolves them). Food from the HSCS is probably not what one has in mind when “food” is mentioned. The food packets generated by the HSCS, while edible, come only in the form of slimy blocks of nutrient-rich “flesh.”

The ship has a very thorough recycling system, tied into HSCS-2, which breaks down anything classified into “waste” into its atomic components. The air recycling system (which is segmented and highly monitored for security reasons) can support up to 11,000 Yamataian or NH-29 personnel up to fifty years. Water can be recycled for fifty years as well.

Conformal PSC Device

The PSC (Psionic Signal Controller) is a form of psionic and telepathic protection, capable of nullifying all such activity. The device can selectively allow channels to permit secure telepathic operation and to maintain communication even under psionic attack. The PSC devices also negate 'magical' attacks and effects. This PSC is safe enough to remain active at all times, unlike older “ADN” devices. The field generated by the PSC protects the entire Mindy, and extends only one meter out past the hull of the ship (thus, it will not create an obvious psionic “dead zone”).

Matter Collection System

The MCS allows the ship to collect hydrogen molecules as it travels through space, which can be used to provide fuel or converted into higher elements for use in the HSCS. The MCS units can be shielded in combat with cover plates.

Nodal System

Trillions of tiny femtomachines are distributed in the air aboard the ship, allowing anywhere to become a control panel with a simple swirl of a person's finger. The ship can use the system to sense what is happening throughout the interior, thus giving it more information to use for environmental control, security, and communication. Using the nodal system, the ship's computer may manifest herself anywhere on the ship in physical or holographic form.


KFY-C8-W2907 Projected Energy Beam Rakers

Utilizing the ships power generation system rather than the CFS for an effect much like for the traditional Projected Energy Beam Cannon except the energy is channeled through two dome turrets and diverged into four parallel beams which can be used to rake across the surfaces of enemy vessels causing extremely heavy damage.

  • Location: Two Dome Turrets mounted on higher portions of the ship behind the bridge dome
  • Primary Purpose: Anti-Starship
  • Secondary Purpose: Heavy Assault
  • Damage: Rating of 5. Total Annihilation in a beam of 1 to 25 meters in diameter.
  • Range: 10 AU
  • Rate of Fire: two twenty-second blasts every 4 minutes.

Dual Port Type 29 Torpedo Launchers

Similar to the Type 26 Torpedo launchers but with improved firing mechanisms, improved tube cover reaction time to protect the tubes during battle. In YE 32 these were modified to fire the new, smaller Z1 type torpedoes. They are capable of firing the Ke-Z1 Series Anti-Starship Torpedoes at a rate of 2 per second.

  • Location: 1 on the midline of the forward bow, 1 midline of aft above and between the two armor bays, and located on the mid-lateral lines both starboard (2), and port (2).
