A starship, also refered to as a spaceship, is the classification given to any vehicle capable of traversing the vacuum of space for an extended period of time, often at FTL speeds. There is enormous variation amongst this particular class of vehicle, with some starships measuring only a few meters in length and others measuring up to several kilometers. Additionally, starships may be modified for military, scientific, or mercantile purposes, as well as providing another form of public transport. Although rules and regulations regarding these particular vehicles vary wildly from civilisation to civilisation, they almost invariably play a important role in any space faring society.

Starships are commonly divided into Military vessels and Commercial vessels.
