The Rak-Miunis was a Kobheerian freighter commanded by Captain Viterian in 2369. That same year, the Rak-Miunis carried the passenger Aamin Marritza to Deep Space 9 from Kora II so that he could set forth his plan to force Cardassia to acknowledge its guilt. (DS9: "Duet")
In 2371, Commander Benjamin Sisko took the Defiant into Cardassian space with modified shield harmonics to disguise them as a Kobheerian freighter. When hailed by an approaching Cardassian ship, Sisko used a holofilter to disguise himself as Captain Viterian and identified his ship as the Rak-Miunis. (DS9: "Second Skin")
