USS Coronado NCC-210

The Rockwell class began development as replacement for the NX class as early as 2156 by United Earth, but would be delayed by the romulan war until 2177, at which point the United Federation of Planets had already been formed. The NX class had begun to show signs of aging, becoming increasingly more difficult to maintain with each refit. So it was decided by starfleet to create an entirely new design to become the new wave of exploratory cruisers. The Rockwell class began to move along in the development process with the involvement of the Andorian Imperial Space Program and their warp 8 project.
