Takagi

In the mirror universe, the free starship Takagi was a Memory Omega jaunt ship in service to the Terran Rebellion, and subsequently the Galactic Commonwealth, in the late 24th century. The Takagi was part of the fleet built by Memory Omega to overthrow the Klingon-Cardassian Alliance.

Wartime
The Takagi was part of the fleet of jaunt ships - battleships with an in-built wormhole generator - Memory Omega built at Erebus Station, beyond the rim of the Milky Way Galaxy. These ships were given to Terran Rebellion personnel after they had received training on the station.

Peacetime
In January 2379, the war was over and the fleet of jaunt ships re-launched with missions of defense and peaceful exploration. In July, Commonwealth Assembly settled on a name for their new, democratic nation, the Galactic Commonwealth.

Its fleet of jaunt ships continued to operate from Erebus Station under the shared auspices of Memory Omega and the newly-minted Starfleet.
