The RX4 Patrol Ship was a vessel used by the Trianii Rangers for long term patrols of Trianii Space. Due to the family nature of Trianii Rangers, these ships had a much more homey interior than was usual for military vessels. Though not a heavy combat vessel, it was more than capable of dealing with the small-time smugglers and pirates that operated in Trianii space.
