Mirror Universe Excelsior-A

The Mirror Universe's version of the Excelsior-A. Lighter than the Starfleet version, it is substantially better armed and shielded but inferior in accommodations and science suite. The two ships have identical endurance and drive packages.

Of existing Federation craft the Mirror Universe ships are mostly closely comparable in fighting power to Sunrise-As, being slightly less well-armed but having identical shields and hull. In terms of peacetime utility, they are effectively closest to a general-purpose Starfleet frigate such as a Centaur-B or Comet.

These vessels had a crew of 771 at launch.
