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
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
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.
