Super Eikan-class Heavy Cruiser

Named after Taisho Eikan Minato, Ketsurui Fleet Yards Ke-C12-2A “Super Eikan” is a larger rebuild of the earlier Eikan Cruiser.

About the Ship

The original Ke-C12-1 series Eikan was a replacement for the older Ayame-class Cruiser. The Ke-C12-2 Super Eikan is an improved, expanded version of the Eikan that replaced the older model in YE 33.

While some other craft are designed with a multi-purpose mission, the Eikan is focused on space warfare; all priorities are second to actual damage output and capacity. Eikan Heavy Cruisers also include a number of countermeasures to overcome enemy technologies designed to work against the Star Army equipment.

Key Features

  • Well-armed
  • Extremely Tough
  • Heavy Sublight Engines
  • Large amount of point defense weapons
  • Countermeasures

Mission Specialization

The Super Eikan specializes in starship combat and large-scale fleet warfare. It is also equipped to serve as a command vessel for small to mid-size squadrons.


The Eikan-Class Heavy Cruiser has a jagged arrowhead shape and a sloped central section. Hull color is the standard Star Army light blue-gray with some dark gray accents. It has two dorsal “pyramids” like the Sharie-class Battleship. It has a large main sublight engine clusters with three smaller engines on either side. The engines glow a bright teal color.

History and Background

Development of the C12 Cruiser began under Taisho Ketsurui Yui in YE 30 as a response to delays and issues with the C10 Cruiser Project (which was eventually canceled). The Star Army's main cruiser, the YE 24 Ayame-class Cruiser, was growing old and Yui's desire for a new battleship, cruiser, and carrier was growing increasingly. The C12 was originally conceived as a small battleship, but was downgraded to a cruiser as the Sharie-class Battleship finally began growing closer to fruition.

A redesign began in YE 32 with a goal of completing the redesign by the end of the year. It had the following requirements:

  • Size increase to 500+ meters to accommodate more fighters, cargo, and anti-starship weapons
  • Standardize weapon turrets

The “Super” Eikan design was highly successful. First introduced in spring YE 33, the Super Eikan has become sought after by fleet admirals. By the end of YE 33 ships of this class had been produced in large numbers and were the backbone of the Star Army of Yamatai fleets.

The Eikan completed its 5-year review in YE 37 and was reauthorized for production and use until at least YE 42.

In YE 42, the Star Army evaluated the performance of the Super Eikan and decided to continue to produce them until at least YE 47.

In YE 43, many Eikan-class cruisers were destroyed in the Battle Of Glimmergold, including 3,882 in First Fleet and 425 in Second Fleet.

Statistics and Performance


  • Crew: A crew of at least 100 is recommended. Due to a high degree of automation, the ship could be operated by a single person.
  • Maximum Capacity: There are accommodations for 200 people. About 500 people could be crammed aboard in an emergency.


  • Length: 525 meters (1,722 feet)
  • Width: 192.5 meters (632 feet)
  • Height: 150 meters (492 feet)
  • Decks: 20 (4 meters each)

Where It Fits


Comparison with a Sharie-class Battleship:

Propulsion and Range

The Super Eikan is designated as a “Category 1” starship (standard warships) by the Star Army of Yamatai and has the following travel capabilities:

  • Sub-light drive capable of speeds up to .375c (~112,422 kilometers per second)
  • Continuum Distortion Drive: 18,750c (~2.14 ly/h)
  • Hyperspace Fold Drive: 394,470c (0.75 ly/m)
  • Sublight Boost: Triple speed available for up to ten minutes
  • Range: Unlimited
  • Lifespan: 20+ years estimated service life
  • Refit Cycle: Frequent minor updates through the PANTHEON system and a refit once every three years

Damage Capacity

See Damage Rating (Version 3) for an explanation of the damage system.

  • Hull: 40
  • Shields: 40 (Threshold 4)

Inside the Ship

The Eikan has an interior that is typical of the Star Army of Yamatai and uses standardized compartment designs.

Compartment Layouts

Ship Systems

Armored Hull

The key substance that makes up the .5-meter-thick hull of the ship is Yamataium. The frame of the ship is Yamataium, while armor plates are made of Yamataium-coated Zesuaium. A Xiulurium coating has also been added to counter aether-detecting sensors and anti-aether devices. All interior passageways and rooms are protected from scalar fields by the internal gravity systems.

Combined Field System

The Eikan has an excellent Combined Field System that can generate an Anti-FTL Field with a 2.5 au radius. The Eikan's CFS field generators are designed to mask the ship's movement and minimize the ship's effect on surrounding space. A “silent running” mode is also available, similar to the one first used on the Yuuko-class Gunboat.

Computer and Sensor Systems

The Eikan uses the MEGAMI Integrated Electronics System package and is also equipped with an Active Jamming System.

Emergency Systems

Escape Pods

Ke-S3-X2900 Escape Pod escape pods are located on decks 3 and 4, and at various other locations on the ship.

Soul Savior Pod

The Eikan includes one Soul Savior Pod.

Life Support Systems

The ship has a very thorough recycling system, tied into a Hemosynthetic Conduit System, 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 500 Yamataian or Nekovalkyrja, Type 33 personnel up to twenty years. Water can be recycled for twenty years as well. Eikan is also equipped with a Psionic Signal Controller.

Power Systems

The Eikan Heavy Cruiser's main power sources are high-output aether generators; the cruiser also includes fusion and anti-matter reactors. The Eikan boasts an extremely robust power distribution system that is built to withstand and control tremendous surges (such as those caused by electrogravitic and electromagnetic pulses and anti-matter ion weaponry). Plentiful capacitors allow the ship to run for a while without any power being produced.

Cooling System

All major heat-generating pieces of equipment are paired with appropriately-sized heat absorbers, which rapidly and effectively absorb thermal radiation and convert it to usable energy.


The Eikan features three methods of propulsion: it carries auxiliary engines for sublight travel, has a hyperspace fold generator, and can also use its combined field to travel at slower-than-light and faster-than-light speeds.

Auxiliary Engines

At the aft of the ship, these four giant engines can move the ship up to cruising speeds of .375c and maximum speeds of .99c (although this can wear the engines heavily) for up to ten minutes.

Combined Field

The primary method of travel in combat. See Continuum Distortion Drive and Combined Field System.

Fold System

Eikan's fold system can reposition the ship to a new location in space. The hyperspace fold generator takes approximately fifteen seconds to charge.

See: Hyperspace Travel

Shield Systems

The Super Eikan uses a standard Combined Field System.
