USS Coronado/Rockwell class ortho

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.

The Rockwell class featured an improved warp drive and impulse engine and introduced directed shielding. The new warp drive included multiple m-am reaction chambers
The class featured directed shielding. A precursor to modern shield technologies, these primitive shields involved the deployment of force fields to defend against what polarized plating could not, lasting a maximum five minutes before an automatic cool-down period. As it's name suggests, directed shielding did not provide full coverage but only in area where it was needed most. The Rockwell class also featured landing gear.

The keel of the USS Rockwell (NX-200) was laid in 2185 and was completed in under 10 months. In the next 50 years, over 300 vessels of this class would be released becoming a staple of Starfleet.

The USS Coranado was launched in 2187
