Stellar-class Warships

Stellar-class Warships are a type of large, fusion powered combat spacecraft utilized by the humans. They were utilized by Fleet International during the Doomsday Battle.

Weapons
Most stellar-class warships are equipped with gamma-ray laser and EM kinetic railgun weapons systems.

Speed
Stellar-class ships have four common acceleration states. Ahead Four is the maximum possible acceleration, capable of traveling at 1/100th the speed of light (2997924.58 m/s).

Deep-sea State
Stellar-class Warships can enter deep-sea state, which fills the ship cabins with a breathable oxygen-rich deep-sea acceleration fluid. The liquid protects the humans against the high forces, allowing them to tolerate the extremely high acceleration. Ships must be in a deep-sea state prior to Ahead Four acceleration in order to ensure crew safety.

Other Attributes
Stellar-class warships have super-antiradiation shielding which gives them some degree of protection from radiation, as noted by the 1,000 km distance that the Combined Fleet maintained from the Trisolaran Droplet prior to the Doomsday Battle.
