Earth starships

Earth Starships were limited to low warp ships before the launch of the NX-01 which was the first warp 5 starship of the NX Class. They became the most advanced starships of the Earth Starfleet when launched in the early 2150's after 90 years of low warp. The first NX class Enterprise launched in 2151 was a major achievement without which The United Federation of Planets would not of exsisted.
