- You may also be looking for the Rigelian freighter (22nd century).
Rigelian freighters were a type of cargo freighter operated by the Rigelians during the 24th century. These Federation vessels were of a completely different, and presumably more advanced, design, than their 22nd century counterparts.
It was used to shadow the Starfleet runabout, taking the fugitive Croden back to Rakhar, while attempting to avoid a Miradorn raider that was scanning all ships leaving DS9, as both ships traveled through the Bajoran wormhole. (DS9: "Vortex")
