The USS Enterprise (NCC-1701-D) (or Enterprise-D, to distinguish it from earlier and later starships with the same name) is a 24th-century starship in the Star Trek fictional universe and the principal setting of the Star Trek: The Next Generation television series. The Enterprise-D also appears in the pilot episode of Star Trek: Deep Space Nine (“Emissary”), the series finale of Star Trek: Enterprise (“These Are the Voyages…”), and the movie Star Trek Generations. The Enterprise-D is a Galaxy-class ship and the fifth Federation starship in the Star Trek universe to carry the name Enterprise. Enterprise-D is the flagship of Starfleet. In most of its service in the Star Trek universe, the commanding officer of Enterprise-D is Captain Jean-Luc Picard. In Star Trek Generations, after combat with the Duras sisters’ ship, the ship’s stardrive section was destroyed and the saucer section crash landed on the surface of the planet Veridian III. The ship was replaced by the Sovereign-class starship USS Enterprise (NCC-1701-E).
