This vessel was used by Ulis and his crew in raiding other starships of their valuable contents. Among the raids for which this vessel was utilized was a raid on a Gavarian ship and another on the Earth starship Enterprise NX-01 in 2151.
Following the encounter with the crew of Enterprise, command of Ulis' starship was handed to his cousin, Krem. (ENT: "Acquisition")
In the final draft script of "Acquisition", this type of ship was described simply as "small." Although on-screen evidence leaves it unclear precisely what form of propulsion the craft used, the script refers to the vessel entering warp at the end of the episode.
