Type-D Basestar,[1] also known as Modern Basestar or Baseship was the primary capital ship used by the Cylons at the time of the Fall of the Twelve Colonies and ensuing 2nd Cylon War. They performed an similar role to the Colonial Fleet's battlestars, that of being armoured fleet carriers/battleship hybrids.
As with most Cylon technology following the Cylon War, the Basestar is organic in origin, and damage can be repaired like a wound regenerating. Within the central section of the Basestar is habitation for Humanoid Cylons and their Centurion servants, with a computer room housing the Hybrid, a Cylon integrated into the ship's mainframe and essentially the personification of the ship.
Above and below this section of the ship are rotating sections, each with three wings coming out in a Y-shape. These sections are the ship's hangar decks. Raiders are embedded within the wings to await launch. These wings can also be entered to reach the hangar deck, which is pressurised. These inner parts of the ship have the organic elements exposed; during a Colonial mission to destroy a Basestar with a nuclear bomb, a Raptor had to land on the flesh. Another bay for Heavy Raiders may also exist, as this flesh was not encountered by Colonial officers during preparation for the Battle of the Resurrection Hub.
While Basestars are heavily armed and can fire a multitude of missiles of different types, from conventional missiles to nuclear missiles to MIRVs, they are not nearly as armoured as their Colonial counterparts, though their regenerative abilities excel a damaged battlestar's requirement for several months of drydock.[2]
