Izumo SFBB-9000

The Izumo class ships are the most powerful ships in the Mars Base fleet. Each massive ship carries an enormous amount of crew, troops, mecha and weapons. Due to the large size and cost only one, the MBSS Izumo, was completed in time to be used in the end of the Inbit conflict as the command ship of the Third Earth Recapture Mission.

The Izumo was largely based on the smaller Ikazuchi class carrier. A pair of secondary weapons pods were added to the sides to carry a pair of enourmous particle cannons and to act as sheilds to protect the enlarged main hull from side attacks. A third, smaller weapons and hanger pod was added to the lower hull of the ship. Surprisingly, the Izumo suffers from the same flaw as the Ikazuchi and Garfish class ships- a lack of Anit-Aircraft armamaent. Hangar decks and crew spaces were distributed through the vessel, including several of the quick-launch bays first used on the Ikazuchis. However, there is a large main Horizont bay located in the lower body, capable of a high turn-around rate on the shuttles. There is no command citadel, though there is a conning tower that rises above the main hull, on which the CIC is located.

VEHICLE TYPE:

• Space Fortress Battle Base

CREW:

• Main Body : 1162 (including command personnel)
• Side Bodies : 250 each
• Lower Body : 275
• Total crew 1937; includes 275 medical, 130 cooks, 232 command/security, 1300 engineers

TROOPS:

• Armo-Fighters & Pilots: 1740
  • Main Body : 1275 pilots for 713 mecha (includes reserve pilots)
  • Side Bodies: 200 pilots for 200 mecha each
  • Lower Body : 65 pilots for 60 mecha
• Ride Armor troops: 1824 combat ready, 1000 in reserve
• Additional Military Personnel: up to 3000 additional troops, personnel, or civilians
• Total troops: 7590

TOTAL OF CREW AND TROOPS:

• 9527, plus an additional 950 personnel can be accommodated in an emergency.

MECHA COMPLEMENT:

Note: This is a typical complement; only 268 Legioss's and 20 TREADs are standard for the ship, while the other mecha belong to other units stationed on board. About 1200 mecha total is normal, but there is storage and hangar space for 1600+ craft.

Fighters: 250 total

• 192 Legioss's in Armo-Soldier Mode stored in one of 8 quick launch bays like those used by the Ikazuchi class carriers.
• 40 Legioss Armo-Fighters or Dark Legioss Stealth Armo-Fighters. They can be replaced 20 Treads or Dark Tread Armo-Bombers or a combination of 10 Treads or 20 Legioss. 10 will usually be Legioss Drones or Jagd Dark Legioss Drones.
• 9 Tread Armo-Bombers or Drak Tread Stealth Armo-Bombers.

  Note: Prior to the Third Recapture mission to Earth, no Dark fighters were in active service in the Mars Base fleet.

Ride Armors: 2800 total

• 1500 VR-052 Mospeada Ride Armors
• 500 VR-041 Blowsperior Ride Armors
• 800 VR-038 Bartley Ride Armors

  This number includes mecha pilot emergency Ride Armors, reserves and special forces assignments.

Other Aircraft (standard, true numbers do not vary significantly):

• 8 Horizont Transatmospheric Carriers,

Vehicles Of Note:

• ~70 AAT-30 and AAT-40 Assault Transports

PROPULSION:

• Reaction-mass thrusters for combat: Fusion-Plasma Reaction Thrusters, capable of a sustained 0.25g acceleration until fuel is exhausted (4.2 hours). 0.5g of acceleration can be sustained for two hours, 1g for one hour, and emergency 1.2g is available for 20 minutes before auto-engine shutdown.
• Emergency thrusters: Fusion-Plasma Reaction Thrusters.
• Planetary Capability: The Izumo can not land on a planet. The thruster systems required would be far too fuel hungry to be fesiable.

MAXIMUM RANGE:

• Presumably unlimited. Fuel supplies give an estimated life of 2 years of constant use. The Izumo's fuel tanks are also used to supply other shorter range ships in the fleet.

DIMENSIONS:

• LENGTH: 1012 meters
• HEIGHT: 304 meters
• WIDTH : 282 meters
• MASS : 16,000,000 tons

MAIN ENGINE:

• Fusion powerplant
• Liquid Hydrogen fueled turbine

GRAVITY CONTROL SYSTEM:

• Internal, including an Inertial Dampening Field.

WEAPON SYSTEMS:

• Synchro Cannon: Has an effective range of 200,000 miles; delivers the equivalent of of a 14 MT weapon. The weapon is located in an aperture in the center body. The Synchro Cannon may fire once every several minutes, each blast can disintergrate what ever target it strikes, be it thousands of Invid mecha, a clam ships or even a Ikazuchi class carrier.
• Two Main particle cannons: Have an effective range of 200,000 miles; deliver 2.5 TJ of particle energy per shot, equivalent to approximately 500 tons of TNT. Can fire once every twenty seconds. One is mounted in each of the side bodies. Cannons can fire separately at different targets or fire coaxially (by themselves, or with the main Synchro Cannon) at a single target.
• 28 Tri-Barrel Gun Turrets: The same upper hull mounted turrets used on the Ikazuchi, with ten on each secondard weapon pods and eight on the main hull. Each turret fires once every three seconds, but the power drain is so great that the turrets can not be fired with the Synchro cannon and the two main particle cannons. Very limited anti-mecha capabilities.

SPECIAL EQUIPMENT OF NOTE:

• Long-range laser and satellite relay communications
• Long-range radar

  The Izumo used in the Third Recapture mission possessed a Dark stealth shielding device.
