System patrol craft are any of a number of capital ship designs that fall between the 100 meter minimum and 250 meters, although some larger ships are relegated to this duty due to lack of available vessels. Systems patrol craft follow the primary directive o apprehend smuggling vessels, but they also serve as a star system's first line of defense against pirates, rebels, and hostile aliens as well.
Most of the vessels that fall into this class are either designed or modified for speed and fire power. Built to engage in "pre-jump" combat, patrol craft make maximum use of speed and maneuverability to catch fleeing vessels before they can escape to hyperspace. System patrol craft contain no hyperspace engines, instead relying on powerful sublight engines to make their way within a system.
Often, the crew of a system patrol craft spends long periods off-world in their vessel, patrolling the borders of their star system. They are called upon to respond quickly to any ships leaving the system with stolen or smuggled goods, so the crews must be constantly on watch for threats from within their system as well as those from beyond. |
