In the 2150s, the Ti'Mur was one of the Vulcan ships participating in the anti-Terran rebellion. Captain Vanik was in command. In September 2155, the Ti'Mur led the assault fleet defending Aldus Prime when the Terran flagship, the USS Defiant and several NX-class battleships attacked the rebel compound to recover Hoshi Sato, empress of the Terran Empire, and the fleets engaged each other in battle.
