T'Plana-Hath was the prototype vessel for the T'Plana-Hath class of surveyors, launched from Vulcan in 2053. Under the command of Solkar in 2063, the T'Plana-Hath landed near Bozeman, Montana on Earth and established the first official contact with humans following the flight of the Phoenix.

According to one account, the T'Plana-Hath was studying potential wormhole eddies that could be created by the interaction of Jupiter and Sol when it detected Zefram Cochrane's warp flight and changed course to investigate. (Star Trek novel: Preserver)
