The workhorse spacecraft of the Thordonian Empire and its navy, the battlecruiser is used for all purposes both military and scientific. Thordonian battlecruisers are usually supplied with their own thordonian consciousnesses and are referred to as of the thordon class of construct with consciousness.

(Update: Battlecruiser Mk II series now takes on the role as general purpose starship.)

Everything beside the main hull, primary power systems, engines, and primary weapons, battlcruisers like most Thordonian constructs are completely reconfigurable. I imagine it's sort of like aperture science where the battlecruiser produces modules that can be relocated throughout the starship. This reconfigurability gives the battlecruiser resilience to damage and allows it to have flexibility in it's roles. The internal structure of the battlecruiser is usually equalized in pressure with the external vacuum of space, although the battlecruiser is capable of producing customizable pressurized habitat modules for passenger biologicals. The battlecruiser also possesses magnetic spinning superfluid gravity generators, allowing artificial gravity to be produced for utility purposes but to also provide comfort for biological passengers native to planetary bodies.
