One of the most important starships in interstellar history, Enterprise (NX-01) was the culmination of the NX Project. The NX-01 was the first NX-class starship, launched by the United Earth Starfleet in 2151. Enterprise established United Earth as a legitimate interstellar power and caused a wholesale revolution in Alpha and Beta Quadrant politics, paving the way for the creation of the Coalition of Planets, and eventually the United Federation of Planets in 2161.
The NX-class was a type of United Earth starship in Starfleet service during the mid-22nd century. The class is notable for having been the first to be constructed with the warp five engine, allowing Humanity to explore beyond neighboring star systems. The lead ship of the class, Enterprise, was launched in 2151, weeks ahead of schedule, while the second, Columbia, was launched in 2154, after lengthy delays in drydock.
