- For the primary universe version of this vessel, please see the USS Constellation (NCC-1017).
In the mirror universe, the ISS Constellation was a Constitution-class Imperial Starfleet vessel in service in the 23rd century. By the 2270s, the Constellation was serving as Grand Admiral Matthew Decker's flagship.
In 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 ordered to attack the Enterprise to the Klingon border to bolster defenses in the area. (TOS novel: Glass Empires: The Sorrows of Empire).
