For the "regular" universe counterpart, see T'Plana-Hath.

The T'Plana-Hath was a Vulcan vessel in service during the mid-21st century. It was the first Vulcan ship to land on Terran soil.

Upon landing in Bozeman, Montana, the crew greeted the first Human to break the warp barrier: Zefram Cochrane. However, Cochrane pulled out a shotgun and led the Terrans to kill the Vulcan crew and raid the ship. History reported that the ship was part of an invasion force. (ENT: "In a Mirror, Darkly")
