One of these ships was part of a six-vessel caravan that fled the Talaxian-Haakonian War in the mid-24th century. It was the only ship that was kept intact after the Talaxians settled on a remote asteroid.
In 2378, the ship deployed sixteen force field emitters on the asteroid to provide protection from Nocona's miners. While it was doing so, it was defended by the Baxial and the Delta Flyer II. (VOY: "Homestead")
