The T'Vran was a Vulcan science vessel that was in service during the mid-24th century. In 2369, the T'Vran was on an exploration mission of the Gamma Quadrant. The T'Vran transmitted messages to other starships through a Vulcan band frequency.
That year, the science vessel T'Vran conducted an exploration mission of the Gamma Quadrant. On its return trip to the Alpha Quadrant, the T'Vran offered assistance to the Starfleet runabout USS Ganges, located on the outskirts of the Chamra Vortex, where it had detected an explosion. Upon offering assistance to the Starfleet runabout USS Ganges its pilot, Odo, requested to have the two Rakhari survivors aboard transported back to Vulcan. (DS9: "Vortex")
