The [[United Federation of Planets (STO)|Federation]] Starship ''Defiant,'' a [[Constitution class (STO)|''Constitution'' class]] cruiser,<ref name="TOS64"/> was constructed at Tranquility Base, [[Luna (STO)|Luna]].<ref name="ENT94"/> During the [[Klingon War (23rd Century)|Klingon War]] of [[2256 (STO)|2256]]-[[2257 (STO)|2257]], the ''Defiant'' and her ''Constitution'' class sister ships were largely redeployed away from the fighting.<ref name="DSC16"/> 

In [[2268 (STO)|2268]], the ''Defiant'' answered a distress call from a [[Tholians (STO)|Tholian]] colony fleet in the [[Murasaki 242 (STO)|Murasaki 242]] [[protonebula]]. The ''Defiant'' soon found itself outmatched by a [[Na'kuhl (STO)|Na'kuhl]] fleet that had traveled back in time in an attempt to spark a war between the [[Tholian Assembly (STO)|Tholian Assembly]] and the Federation. Aided by the [[U.S.S. Pioneer NCC-1500 (STO)|U.S.S. ''Pioneer'' NCC-1500]], which had also traveled back in time from [[2270 (STO)|2270]], they were able to prevent a war, but not to save the Tholians. When the Tholian [[Recluse class (STO)|mothership]] rammed the Na'kuhl [[Khaerops class (STO)|dreadnought]], the chronal energies released, coupled with the unique properties of the protonebula, caused an [[interphase (STO)|interphasic]] rift that trapped the ''Defiant.''<ref name="STOWebs"/>

This interphase had an adverse effect on humanoid neurophysiology and caused mass insanity among the crew. [[Starfleet Captain (STO)|Captain]] [[Morrison, Gil (STO)|Gil Morrison]] managed to get a distress call out to the [[U.S.S. Enterprise NCC-1701 (STO)|U.S.S. ''Enterprise'' NCC-1701]] before the crew succumbed to madness and started to kill each other. By the time the ''Enterprise'' arrived at the ''Defiant's'' location on [[Stardate]] [[2268 (STO)#SD5693|5693.2]], three weeks had passed. The crew of the ''Defiant'' was dead, and the ship had been drawn deeper into the interphase rift. Interference from the Tholians prevented the ''Enterprise'' from retrieving the ''Defiant,'' and the ship was left behind. The ''Defiant'' was last seen shimmering, suspended between dimensions, until it faded into interspace.<ref name="TOS64"/>

The interphase, however, was actually a rift between realities created by the Tholians of the [[STOM Timeline|Mirror Universe]] in [[2155 (STOM)|2155]]. The ''Defiant,'' after disappearing from its universe of origin, appeared in that universe and was taken by the Tholians to a drydock in the [[Vintaak system (STOM)|Vintaak system]] for study. Word of this eventually reached [[Terran Starfleet Commander|Commander]] [[Archer, Jonathan (STOM)|Jonathan Archer]], first officer of the [[I.S.S. Enterprise NX-01 (STOM)|I.S.S. ''Enterprise'' NX-01]], who saw the ship as an opportunity to seize power for himself within the [[Terran Empire (STOM)|Terran Empire]]. He seized control of the ''Enterprise'' from [[Terran Starfleet Captain|Captain]] [[Forrest, Maximillian (STOM)|Forrest]] long enough to reach the ''Defiant.'' While Archer led a boarding party to the ''Defiant,'' the ''Enterprise'' was detected by the Tholians and destroyed.<ref name="ENT94"/> Using the ''Defiant's'' advanced weapons, Archer was able to rescue most of the ''Enterprise'' crew and escape back to Imperial space, where it quickly became obvious that the balance had just tipped back in favor of the Empire in an ongoing civil war, led by [[Vulcans (STOM)|Vulcans]] and [[Andorians (STOM)|Andorians]] who sought to unseat the [[Terrans (STOM)|Terrans]] in control of the Empire. The ''Defiant'' rendezvoused with an assault fleet, but discovered the [[I.S.S. Avenger NX-09 (STOM)|I.S.S. ''Avenger'' NX-09]] was the only ship remaining. Destroying the rebels, Archer then proceeded to assassinate [[Terran Starfleet Admiral|Admiral]] [[Black (STOM)|Black]], and decided he was going to use the ship from the future to overthrow the Emperor. The alien crew members on the ''Avenger,'' however, led by [[T'Pol (STOM)|T'Pol]] and [[Soval (STOM)|Soval]]&mdash;inspired by the ''Defiant's'' database, which described a United Federation of Planets in the other universe&mdash;convinced [[doctor|Dr.]] [[Phlox (STOM)|Phlox]]&mdash;the only remaining non-Terran aboard the ''Defiant''&mdash;to disable the ship, allowing the ''Avenger'' to attack. However, the crew was able to restore the ship's systems and destroy the ''Avenger,'' killing Soval. Shortly after arriving at [[Earth (STOM)|Earth]], Archer was poisoned by [[Sato, Hoshi (STOM)|Hoshi Sato]], formerly the Captain's Woman to Forrest and an old flame of Archer's as well, who then declared herself [[Terran Emperor (STOM)|empress]].<ref name="ENT95"/>

By [[2257 (STOM)|2257]], after more than a century in the [[STOM Timeline|Mirror Universe]], the ''Defiant'' had seen numerous modifications by the [[Terran Empire (STOM)|Terran Empire]]. The [[U.S.S. Discovery NCC-1031 (STO)|U.S.S. ''Discovery'' NCC-1031]], while briefly stranded in that reality, downloaded information about the ''Defiant'' from the Terran Empire's computer networks, as well as secured files aboard the flagship of the [[Starfleet (STOM)|Terran Starfleet]], the [[I.S.S. Charon (STOM)|I.S.S. ''Charon.'']]<ref name="DSC10"/><ref name="DSC12"/>
