| | USS Defiant (NCC-1764) - Memory Alpha |
 | | The Defiant emerged in the mirror universe during the 22nd century, where it was discovered that Tholians in that universe had created the interphasic rift by detonating a tri-cobalt warhead within the gravity well of a dead star, and had sent the distress call which had lured the Defiant to the area. |
 | | At that time the Defiant was visible in the "normal" universe at interphase, then, as a result of a later phaser exchange between the Enterprise and the Tholians, created a hole through the spatial interphase, which was pushing the Defiant to parts unknown, trapping Kirk between universes. |
 | | The Defiant's mission patch is an insignia similar to the pennant on the sides of TOS starships and seen as a set decoration on starbases of that era. |
