For the primary universe counterpart, see USS Defiant (NX-74205) (I).

In the mirror universe, the ISS Defiant (NX-74205) was a warship constructed by the Terran Rebellion, and was based on Defiant-class specifications stolen from Deep Space 9 in 2371. Once operational, the Defiant helped turn the tide in the war against the Klingon-Cardassian Alliance, especially at the Battle of Terok Nor, and represented a major boost to the rebels' morale.

Service history[edit | edit source]

The specifications for the Defiant were stolen by Miles O'Brien during a visit to the primary universe. "Smiley" O'Brien was able to download the schematics from Deep Space 9's computers and brought them back to the mirror universe, where construction began at Terok Nor, now under rebel control. While construction proceeded well with materials stolen from the Alliance, the powerful warp core on the Defiant caused the ship to almost shake itself apart during test flights, much like had occurred with the counterpart version.

With an Alliance fleet on its way to retake the station, O'Brien enlisted the help of Professor Jennifer Sisko to bring Captain Benjamin Sisko into the mirror universe, so that he could solve the problems on the Defiant. Sisko was able to iron out the problems and even commanded the Defiant in the fight against Regent Worf's fleet. (DS9 episode: "Shattered Mirror"; WizKids module: Tactics)

The Defiant attacks the Negh'Var.

In mid-2375, the Defiant was used to pursue Ezri Tigan and Brunt and to repel a further attack by the Alliance. (DS9 episode: "The Emperor's New Cloak")

A few months later, Rebellion Generals Zek and Julian Bashir gained the resources to build twenty-four more Defiant-class warships at their new shipyard at Empok Nor. Twelve of these were made, including the Capital Gain, Jadzia and Terra Victor. However, eleven were destroyed in the explosion that destroyed Empok Nor, and the Capital Gain was disabled.

The remaining twelve warships were built some time later by O'Brien as part of his plan for a Alpha Quadrant-wide "revolution" against the Alliance. That made a total of thirteen Defiant class warships including the Defiant herself. (DS9 - Obsidian Alliances novella: Saturn's Children)

In early 2377, Leeta was in command of the Defiant. (DS9 novel: The Soul Key)

In January 2379, Ezri Dax assumed command of the Defiant under the Galactic Commonwealth. (ST novel: Rise Like Lions)

Background[edit | edit source]

While the vessel was never actually named onscreen as the ISS Defiant, the ship's dedication plaque - barely visible onscreen - referred to it as such.
