Police Ships
Crime never disappears, whether it's black marketeers, smuggling, starship theft, murder, or accidentally stepping on some minor nobles foot at the spaceport. No Noble House can afford to allow crime to run rampant in its systems, to combat the threat of pirates and smuggles Houses deploy Police Ships. The crews of which are specially trained and equipped for search and seizure.
In Fading Suns, Police Ships are usually small Raider, Escort, or Frigate class vessels who's design focuses upon speed, and are armed with disable guns and small but elite marine boarding crews. While there weaponry is comparatively light to that of a front line warship, most pirate crews posses nothing greater than a converted tramp hauler and some light lasers or slug guns. Fighting crime while not as glorious as a military battle is still a battle, so go out and get that guy who stepped on my foot!
