Heitan-Class (1B) Carrier

The Heitan-class is a multi-role fighter craft carrier created by Ketsurui Fleet Yards for the Star Army of Yamatai first manufactured in YE 31. In YE 42 the Heitan underwent a massive design overhaul.

About the Heitan-class

The Heitan-class is designed to provide a formidable fighter presence in combat areas. The carriers are not intended to directly engage enemy capital vessels. They are equipped with weapons to protect them from enemy missiles, fighters, and other small craft. They are typically part of a battle-group and depend on the vessels in that group for protection from enemy warships. The overhaul made radical changes to the ship offensive and defensive arsenal. The overhaul also made significant enhancement to the ships capacity to carry and launch fighters.

History

With the Kuvexian War it was determined that the Heitan Class Carrier needed a major refit. This prompted Mikasa Sorano-Taisho to have Libra Star Fortress began evaluating new technology and how to make use of it. Takumi was the Chief designer of the refit.

Appearance

The Heitan-class basic appearance not only gave rise to its name Heitan meaning flat, but was intended to offer the smallest profile to the enemy. Attached to the main section are the hangar modules mounted above and below. The ship's hull is two-toned, with some parts a dark gray while other parts are the standard blue-gray. As with all modern Star Army vessels, it is marked with a Star Army Hinomaru on its dorsal surface.

Unique Compartments

The following compartments are unique to the Heitan.

Side View

Flag Bridge

The Heitan has a second Standard Medium Starship bridge. It is for use by an embarked Admiral and their staff. It is located beneath the bridge.

Hangar Deck

The Heitan has three separate hangar decks.

Alpha and Beta

Alpha and Beta are identical in size and configuration and are for fighters. They are located on the upper portion of the ship. Alpha and Beta deck are 440 meters long, 160 meters wide and 13 meters high with 2 meters of maintenance area beneath each. Forward of each hangar is the launch/recovery bay and aft of it is the workshop. Each hangar has 84 berths which means each can hold seven squadrons of fighters.

Hangar Layout

Launch/Recovery Bay

At the forward end of each hangar deck is the launch/recovery bay. Each bay has a containment force field on the entrance as well as an armored door. A Durandium Alloy blast shield protects the interior of the hangar from the engine exhaust. Alpha and Beta hangar decks have two bays. Each bay can launch four fighters arranged two side by side. Each bay also has several KFY Graviton Beam Projectors to assist damaged craft with recovery.

Upper bays

Berth

Each fighter craft assigned to the Heitan has a specific berth location in the hangar decks. This is where the craft are checked, and prepared for their mission. Each has diagnostic interfaces and a standard Star Army Tool Locker. Each berth is typically 20m x 20m but the space can be reconfigured to accommodate larger craft should it be necessary. Every fourth berth has a Firefighting Version of the tool locker. These are indicated on the hangar layout by red circles.

Pallet

Craft on the hangar deck are placed on pallets which are used to move them from their pit location, to the workshop, or the launch/recovery bay. Each pallet is hexagonal and has configurable clamps that secure the craft to the pallet.

Gamma

Gamma is as large as the other two combined and is intended for special equipment. Gamma deck is 440 meters long, 160 meters wide and 28 meters high with 2 meters of maintenance area beneath it. It has a single large launch recovery area.

Lower bay

Workshops

Aft of each hangar deck is the workshop. This is where craft that have sustained structural damage are taken for repair or cannibalization. Between the ship's fabrication and the workshop, a Heitan can manufacture replacement fighters if necessary.

Hyperspace Field Boosters

The Heitan has a pair of hyperspace fold emitters which allow the carrier to produce a fold bubble large enough to encompass the entire compliment of fighters and jump with them deployed. They are located on the sides of the carrier.

The Boosters allow the Heitan to generate a hyperspace bubble of one kilometer in radius.

Primary Flight Control

This is where all launch and recovery activities are controlled on the Heitan. The room has several Volumetric Display displays that show the status of each Launch and Recovery bay. They also display the position of all the craft around the carrier.

Weapon placements

The Heitan features a wide range of state of the art weaponry.

Type 31 Secondary Anti-Starship Turret

  • Mounted laterally along the sides, three to each side on the top and another three mirroring the top placements.

Point Defense Turrets

  • Eight on the top and bottom of the bow, and eight on the top and bottom of the stern.
  • Four on the top corners of the upper and lower pyramid.
  • Six on top of the Alpha hangar
  • Six on the bottom of the Gamma hangar
  • Twelve laterally at the side paralleling the hangars

Anti-Armor Missile Launchers (retractable)

  • Seven mounted on the 'wings' protecting the Hyperspace Booster assembly.

Star Army Ke-Z1 Torpedoes Launchers

  • Launched from 5 launchers on the port and starboard wings.
  • The launchers are a modified Ke-D7-W3900 Mass Launcher which fire the missiles from the tube.

Ship Systems

This section contains the unique system information for the Heitan.

Armored Hull

The Heitan has a one meter thick hull of Yamataium. The frame of the ship is Durandium Alloy. All windows on the Heitan are made of Transparent Durandium. The ship's hull is painted in Omnihue.

Computer and Sensor Systems

The Heitan uses a KAMI for command and control of shipboard systems and is equipped with a Psionic Signal Controller.

Blast Shutters

On the Heitan Forcefield-Nested Isolation Doors are used.

Flight Launch System

Scalable Graviton Beam Projector Array

Propulsion

The Heitan uses five Ketsurui Fleet Yards Multi-Stage Aether Drive drives for propulsion at sub-light speeds.

The Heitan uses a Ketsurui Fleet Yards Integrated CFS Array for FTL propulsion

The Heitan has two Ketsurui Fleet Yards Hyperspace Fold Engines. One is sufficient to allow the carrier to travel. However for certain combat situations, the Heitan uses both of them to create an extended hyperspace bubble to allow it to deploy its compliment of fighters, take them into hyperspace for rapid engagement of the enemy when they drop out.

Weapons Systems

The Heitan is primarily focused toward defending the ship.

Vehicle Complement

Gamma Hangar

The number and type of craft carried in Gamma Hangar depends on the mission.

Alpha and Beta Hangar

Non-technical data

Tactics

The following are the more common tactics the carrier uses.

Strike Mision

The carrier gets to within range of its objective. It then launches Ke-V7 "Ginga" Bombers and fighter escorts. Two Bombers are paired with a Squadron. The Ke-V7 "Ginga" Bomber then uses their hyperspace fold system to take 6 fighters as escort. Once they return to normal space the bombers make for the objective while the fighters provide cover for them.

Assault Mission

The carrier launches its contingent of Fighter Squadrons and whatever other craft are deemed appropriate. Two of them are designated as CAP to defend the carrier when it arrives. It then jumps into hyperspace using the field boosters taking all of the launched craft with it. When it arrives the fighters are already launched and can immediately engage the enemy.
