Throughout the history of the universe, there have been multiple timelines, alternate realities and parallel universes that have contained versions of SS Enterprise NX-01, as well as various duplicates.
In February 2152, Doctor Phlox witnessed a possible future where Nausicaan pirates attacked Enterprise. Phlox comforted the future Charles Tucker III as he lay dying. (ENT - Strange New Worlds VI short story: "Cabin E-14")
In alternate timeline created when Jonathan Archer was infected by interspatial parasites, the Xindi destroyed Earth and Enterprise, under the command of Captain T'Pol, led the fleet of surviving Human ships to Ceti Alpha V in 2154. In 2165, the Xindi attacked the Ceti Alpha system and crippled Enterprise, which was subsequently destroyed in a subspace implosion, resetting this timeline. (ENT episode: "Twilight")
In another timeline involving the Xindi, Enterprise was thrown back in time during the passage of a vortex. Arriving in 2037, Enterprise remained in the Delphic Expanse to avoid contaminating its own history. In 2154, the generation ship Enterprise, commanded by Captain Lorian, caught up with Archer's ship. They cooperated to outwit the Kovaalan inhabiting the nebula surrounding the vortex, allowing Archer's ship to avoid time displacement during the passage. Lorian's ship remained behind, presumed destroyed or erased from time. (ENT episode: "E²")
In an alternate timeline beset by the temporal anomaly crisis, Lorian's generation ship was pulled into the late 24th century. Around the year 2380, different timelines were interwoven, and this Enterprise joined Federation Starfleet to help Q resolve the temporal anomaly crisis. (ST video game: Timelines)
In a universe where Terra Prime successfully attacked San Francisco in 2154, United Earth pulled out of the Coalition of Planets talks. Jonathan Archer continued to take Enterprise on missions to support the fledgling Interstellar Coalition. A century later, former first officer T'Pol was a decisive voice on Earth's behalf to join the IC during the Babel Conference. (ST - Myriad Universes novel: A Less Perfect Union)
In a version of events where Vulcans remained a violent and emotional species, Andoria became the target of the Xindi instead, and its was Commander Thy'lek Shran of the IGS Kumari that carpet-bombed the Xindi into submission. (ST - Myriad Universes novel: The Tears of Eridanus)
- The author's annotations stated Enterprise launched ten years later due to the lack of Vulcan support after World War III. The construction was finalized under Jonathan Archer, and Bryce Shumar became its captain. Coming a decade late, Andorians became the dominant power by force instead of the Human power-brokers.
In the Kelvin timeline, Enterprise NX-01 was considered historically significant. In the mid-2240s, a holographic NX-01 floated in the bedroom of James T. Kirk. (TOS - Star Trek (IDW) comic: "Operation: Annihilate, Part 1")
In the mirror universe, the ISS Enterprise enforced the brutal rule of the Terran Empire. It was destroyed by Tholians in 2155 during a mission to recover the time-displaced 23rd century Federation Constitution-class starship USS Defiant. (ENT episode: "In a Mirror, Darkly")
