VX-391 functioned as a cargo transport vessel. It transported the frozen bodies of individuals such as Anakin Skywalker, Obi-Wan Kenobi, Ahsoka Tano, in addition to various clone troopers who were all encased within carbonite blocks.
The spacecraft was flown by R2-D2, who achieved this by taking control of a B1-series battle droid. This was necessary because all living beings detected onboard would be subjected to irradiation, resulting in their vaporization. Following the successful completion of the freighter's inspection, Juhm inquired with the irradiator operators regarding the presence of an additional vessel within the transport group. As the freighter began its descent into the atmosphere of the planet Gwori, the entire convoy received instructions to alter their trajectory. However, R2-D2 was unable to comply, thereby exposing the freighter as an illegitimate participant. In the moments leading up to the ship's destruction by droid fighters, Artoo deployed both the carbonite encased bodies and himself, ejecting them onto the sandy surface below.
