In the mirror universe, the ISS Intrepid (registry NCC-1631) was a Terran Empire starship, a Constitution-class battle cruiser in service to Starfleet in the late 23rd century. By the 2290s decade, the Intrepid was refit as an uprated Enterprise-subclass vessel.
In the 2290s, the Intrepid and the ISS Constellation were assigned as escorts to the deadly planet killer, which the Terrans had harnessed control of recently and were using to subjugate the Klingon Alliance. During the supposed rebellion of Captain Sulu and the crew of the ISS Excelsior, the Excelsior arrived in Klingon space under command of the counterpart universe's Captain Sulu and his crew, and found most of the territory had been devastated by the planet killer. Fortunately, Sulu was able to stop the weapon by disabling the ISS Kodos and allowing the planet killer to swallow it, depleting its power fully after it had already been significantly weakened from attacks from three K'tinga-class battlecruisers. Intrepid and Constellation took heavy damage from a combined fleet of Excelsior fighters, Klingon birds-of-prey, and Klingon Hunter-classs and went missing in the battle.

- The game objective did not require the destruction of the Intrepid and Constellation, but it did not effect the outcome of the round if the two vessels were demolished.
