IV. Propulsion Systems:

(All):

• Maneuvering thrusters (24): Flygmotor T-300 fusion-plasma reaction thrusters with steerable nozzles. Four are located in the bottom, four each on the sides of the nose, four on each sponson and four on top of the vessel.
• Reaction-mass thrusters (4): Westinghouse RT-82 fusion-plasma reaction thrusters with protoculture energizer mounted in a diamond configuration in the rear of the main hull.
• Emergency reaction-mass thrusters (4): SNECMA BCET-6T fusion-plasma reaction thrusters with protoculture energizer paired in a vertical arrangement outside of the side main reaction thrusters.
• Anti-gravity system (1): 3 RRG Titan anti-gravity pods.
• Spacefold drive (1): RRG Mk3 spacefold drive. This system generates a small fold bubble.
• Planetary Capabilities: The Tristar and Argonaut have atmospheric capabilities through their reaction thrusters and anti-gravity system. The hull has sufficient structural strength for the ship to make a cold landing on it. Note that the ground underneath should be as firm as possible.
  The Ajax has atmospheric capabilities through its reaction thrusters and anti-gravity system. The hull overall has sufficient strength for the ship to make a cold landing, but if the ground is not firm or smooth enough, the possibility of damaging the ventral landing ramp increases greatly. A prepared site is preferred, but operating the anti-gravity system at -99% of the local gravity is an acceptable alternative.
  All classes will float in an ocean, but the main access ports in the hangar, as well as the ventral landing ramp of the Ajax, will be submerged and inaccessible.

(Tristar, Ajax, Argonaut):

• Main power system: RRG Mk. 12 Reflex furnace. The original powerplant can deliver up to 526 terawatts of power, and can operate at maximum output for up to 67 minutes before overheating and automatic shutdown.

(All B flights):

• Main power system: RRG Mk. 12A Reflex furnace. This new powerplant can provide up to 530 terawatts of power, and can operate at maximum output for up to 75 minutes before overheating and automatic shutdown.

V. Endurance and mobility limits:

• The dry stores endurance is limited to about ten months for the Tristar and Argonaut, and two months for the Ajax; after such time the ships will need to restock. Water stores are recycled almost completely. Hydroponics installations are often installed in slack space, providing the crew with a medium supply of fresh fruits and vegetables, but will be insufficient to sustain the crew indefinitely.
• The Navy mecha consumables of all classes are somewhat limited; the Tristar and Argonaut are able to sustain combat operations for twenty-four days, while the Ajax can only support ten days of combat operations.
• The Army unit consumables of the Ajax are enough to sustain ground combat operations for twenty-eight days.
• Ship-launched missile magazines will be empty after two major battles or three small skirmishes.
• The Reflex furnace can function for about 25 years at normal usage levels before an energizer rebuild is necessary.
• At full power, the main propulsion systems can produce up to 10.7 Giganewtons of thrust at a minimal reaction mass efficiency profile, or as little as 0.26 Giganewtons of thrust at a maximum efficiency setting. At lower power levels, these thrusts are commensurately smaller.
• At full power, the Tristar and Ajax classes can achieve a maximum Δ-v of 166 kps at the cruising acceleration of 0.1 gees, a maximum Δ-v of 33.2 kps at the battle acceleration of 1.0 gees, and a Δ-v of at most 9.3 kps at the flank acceleration of 2.5 gees. At lower power levels, these ranges are commensurately smaller. For any change in weight, there is a proportionally equivalent penalty or bonus applied to these figures.
• The fold systems are not navigationally guaranteed for any single jump beyond 10 kiloparsecs. If longer voyages are required, the ships must conduct multiple fold jumps.
• The maximum sustained atmospheric speed is Mach 3. The maximum hover time on the anti-gravity systems is limited only by the protoculture supplies and maintenance requirements, but the system is too weak to lift the ship against gravities of more than 1.1g without assistance from the reaction thrusters. In fact, even at 1.0g the bottom-mounted maneuvering thrusters are often used to reduce the strain on the anti-gravity systems.
