Enterprise (NX-01)
The USS Enterprise (NX-01) is a prototype starship developed by Earth's Starfleet with some assistance from the Vulcans. It is the setting for the series Star Trek: Enterprise.
Technical Specifications
The Enterprise was the first Earth-built starship to mount a warp drive capable of achieving Warp 5, although even that was mostly a theoretical limit.
When the ship left port, it was armed only with torpedoes of unspecified yield which proved to be rather feeble compared to the weapons carried by the ships of other space-faring races. The crew were able to install three phase cannons without returning to Earth for a refit, substantially improving the ship's combat capability. The ships original torpedoes were eventually replaced photonic torpedoes during a refit at Earth. The ship relied on polarized hull plating to reduce damage from enemy weapons.
The Enterprise was the first Earth ship to mount a transporter system, but the device was not generally trusted and only used to transport living people as a last resort.
