The Quasar Fire-class bulk cruiser, also referred to as the Alliance escort carrier or the Quasar Fire-class cruiser-carrier, was a modular starship typically used for freight. Designed by the Sullustan megacorporation SoroSuub, the Quasar Fire-class bulk cruiser resembled a triangle, with the bridge at the frontal point and the cargo bay at the base. The cargo bay could be modified to house various freight modules or, in some cases, passenger modules.
Originally built as cargo vessels by the SoroSuub Corporation, the Quasar’s cargo bay could be modified by the owner to accommodate different types of freight modules. Although unarmed in its stock configuration, many operators installed an assortment of defensive weaponry to deter pirates. Several ships were converted into fighter carriers by the Virgillian insurgency, a modification they later shared with the Alliance who were in desperate need of ships.
