A non-starship specifically intended for defensive operations inside a star system.


System Defense Boats (SDB's) range in size from 100 to 10,000 tons and are constructed at all tech levels from TL 8 to 15. There are hundreds of different types, depending upon the specific mission for which they are designed.

Please see Military Starship Types for more information.

Strategy and doctrine[edit]

SDBs most often operate according to predetermined plans designed to optimize their defensive potential. SDBs are typically stationed at the vital points of a system including gas giants, asteroid belts, major worlds, and so on.

Because SDBs usually have no jump drives, shifting them from system to system can be a problem. Some types have jump shuttles which fit to the craft and provide jump capability.

Another method is simple transport in large bulk cargo containers; the SDBs are loaded into 10,000-ton or 20,000-ton bulk carriers for the multi-parsec journey. This method, of course, is not recommended if immediate combat is expected at the destination.

History and background[edit]

SDB's were developed on the principle that a non-starship, because of the additional armament made possible by its lack of jump drives, can ordinarily defeat a jump-capable starship of equal tonnage.
