The Ruby class battlecruiser is a highly potent vessel designed for maximum firepower in a fast, sleek package. It is an excellent interdiction vessel, superlative in the arts of flanking sweeps and the annihilation of enemy supply convoys behind the lines. It features battleship-level firepower in a fast package which can keep up with cruisers, making it a popular command ship for missions that require speed above toughness. However, it lacks a battleship’s ability to take punishment, requiring dexterity, restraint and opportunistic aggression in equal measure from its captain. The Ruby is armed with a pair of disruptor banks and a pair of lethal particle lances – weapons which can slice through any armour ranged against them.

The Sapphire class is a more specialised and unusual vessel, conceived for disruption and close range engagements. In combat, it relies on a pair of ion storm generator banks to inflict crippling damage at close range with the option of use in the orbital bombardment role. Its second main armament is a pair of gravity coils. These forward facing constructs create a highly localised and damaging beam of gravitic disturbance, ripping chunks from hulls, crushing bulkheads under their own weight and even changing the heading of a multi-thousand ton warship, disrupting the battle plan of any foe.
