System Defence Boat (SDB)

System Defence Boat (artist Jesse DeGraff, used with permission); click for larger imageA non- starship (a spaceship) specifically intended for defensive operations inside a star system. Developed on the principle that a spaceship, with increased armament and defences due to lack of jump drives, can normally defeat a starship of equal tonnage. SDB's are typically stationed at the vital points of a system (the gas giants, the asteroid belts, the major world's oceans, and so on) and attack invading vessels according to one or more pre-determined plans.

System Defence Boats range in size from 100 to 5000 tons and are constructed at all tech levels from 8 to 15. There are hundreds of different types, depending upon the specific mission for which they were designed.
