In early 2370 the K'Tang was dispatched from the Klingon Empire on a scientific exploration mission to the Gamma Quadrant. Before entering the Bajoran wormhole, the K'Tang docked at Deep Space 9 for shore leave and to receive replacement crewmembers from a visiting Klingon Bird-of-Prey. (DS9 - Hearts and Minds comic: "Prelude") In "Into the Abyss", Dax describes the K'Tang as being a K't'inga-class warship. This is at odds with the vessel's mini-series appearance as a Vor'cha-class cruiser.
