Throughout the history of the universe, there have been multiple timelines, alternate realities and parallel universes that have all contained versions of the starship type commonly known as Constitution-class, as well as various refits and facsimiles.
Alternate mirror realityEdit
The Constitution-class was a type of starship operated by the Terran Empire Imperial Starfleet as a heavy cruiser and flagship in the 2250s of the Kelvin timeline mirror universe. One notable member of the class was the ISS Enterprise, which launched in 2258. The Enterprise was destroyed by the Romulan mining ship Narada when James T. Kirk took it over and killed Nero.
