In the mirror universe, the ISS Constellation (registry NCC-1017) was a Terran Empire starship, a Constitution-class battle cruiser in service to Starfleet in the late 23rd century. By the 2270s decade, the Constellation was refit as an uprated Enterprise-subclass vessel. (TOS video game: Shattered Universe)

Service historyEdit

In the late 2240s, the Constellation served as Commodore Robert April's flagship. April took the ship to H'atoria and attacked a Klingon research outpost, engaging in a battle with four Klingon warships. The Constellation emerged victorious but the ISS Indomitable was destroyed in the process. (Mirror Universe short story: "Ill Winds")

By 2257, Matthew Decker held command. In that year, the Constellation traveled to Qo'noS to deliver Emperor Alexander's gene-weapon. Before the genocidal weapon could be unleashed on the Klingons, the rogue ISS Shenzhou attacked the Constellation, blasting its warp nacelles apart, and Captain Airiam seized the weapon. (DSC - Discovery - Succession comic: "Issue 3")

By the 2270s, the Constellation was serving as Grand Admiral Decker's flagship, as well as Starfleet's actual flagship.

In the year 2277, the Constellation, under orders from Empress Hoshi Sato III, led a fleet of Imperial Starfleet vessels to the Terra Nova system in the hopes of ambushing and destroying the ISS Enterprise. When the Enterprise arrived in the system, Admiral Spock quickly surrendered and had himself beamed aboard the Constellation to hear the charges laid against him by Admiral Decker.

Unfortunately, Spock had managed to persuade the Constellation's first officer, Commander Hiromi Takeshewada, to lead a mutiny and assume command of the Constellation. Mutinies by officers loyal to Spock also took place on starships all across the fleet, and in order to withold her position, Empress Sato III appointed Spock the new Grand Admiral of Starfleet.

Spock's first actions were to promote Takeshewada to captain and ordered that she take the fleet (which had been ordered to attack the Enterprise) to the Klingon border, so as to bolster defenses in the area. (TOS - Mirror Universe novel: The Sorrows of Empire)

In [[2293], the Constellation and the ISS Intrepid 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't'inga-class battlecruisers. Intrepid and Constellation took heavy damage from a combined fleet of Excelsior fighters, Klingon birds-of-prey, and Klingon Hunter-class and went missing in the battle. (TOS video game: Shattered Universe)

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