SJ supports the expansion of Spacefleet and its pre-emptive use against the Sathar. In addition, it has proposed many bills supporting UPF exploration and colonization in the direction of suspected Sathar-controlled star systems in order to gain a strategic advantage. SJ is slightly larger than the Central Party with whom it often allies.The party is led by the Yazirian Maxxer Trej of Yast. Trej is famous for her time in Spacefleet when as captain of the light cruiser UPFS Intrepid a misjump landed the ship in an uncharted star system filled with Sathar spaceships.
