Constellation Strike Frigate

Believed to be from the Mirror Universe, though there is some doubt, the Constellation Strike Frigate is a version of the Starfleet Constellation refitted to frigate construction standards and used as a combat craft. Several reverse-engineered models are employed in this universe as policing craft by the Emporium, a trading nation near the Trill, Gorn, and Ittick-ka.

In comparison to Federation craft they are awkward matches, with the firepower and shielding of a Centaur-B but the hull of a stock Constellation. Their science package falls between those of a Constellation and a Constellation-A, but their accommodations are inferior to either. They have the endurance, and probably the impressive warp sprint speed, of a Constellation-A.
