Antares-class freighters were a type of starship used by several races during the 24th century, most notably the Bajorans, Cardassians, and Corvallens. These vessels commonly served as cargo ships or transports. (TNG: "Ensign Ro", "Face of the Enemy", DS9: "Life Support", "Rules of Engagement")
- This class was named after the ill-fated starship from "Charlie X". The Corvallen-used version was a different, but similar, model from the Bajoran/Cardassian variety. It seems unlikely that the Federation would use the same designation for two vastly different starship types, so it might be assumed that the Corvallen freighter is a variant of the Antares-class.
