|Class:||Constitution (Enterprise refit)|
The USS Enterprise (NCC-1701-A) was the second Federation starship named Enterprise, commissioned in 2286 under James Kirk's command to replace its destroyed predecessor. After several years of operation, the Enterprise-A was decommissioned in 2293 following the Khitomer Accords, and replaced six months later by the Excelsior-class Enterprise-B. (Star Trek IV: The Voyage Home, Star Trek VI: The Undiscovered Country)
Nearly 100 years after its retirement, the ship was commandeered by Admiral Kirk (who somehow survived the events on Veridian III) and Ambassador Spock to travel back to 2266, joining Fleet Captain Pike and Captain Kirk to retrieve the device now dubbed, the Doomsday Machine. Due to the efforts of the three ships in 2266, the Machine arrives back in the 24th century, where it is immediately rendered harmless. ("In Harm's Way)"
In 2380, the Federation starship USS Titan, while on a scientific survey of the Gamma Quadrant, discovered the saucer section of the Enterprise-A, which somehow survived the events of Chal in 2293 and appeared on planet Gamma Germanicus VII. With the help of several students from an educational institution named Hogwarts School of Witchcraft and Wizardry, the Titan away team was able to fly the saucer off planet.
Later, at Deep Space 9, the saucer was mated to a surplus refit Constitution-class stardrive section and flown to Earth for a massive refit. This refit entailed bringing the Enterprise-A up to current standards, including the additions of facilities non-existent on the original Enterprise-A, including a USS Voyager-like Astrometrics lab and a Ten Forward lounge nicknamed the "Leaky Cauldron," after the favorite drinking establishment of the ship's now-largely Hogwarts-based crew.
After said refit, the re-commissioned Enterprise-A was instrumental in the return of James T. Kirk from the Nexus energy ribbon and the Federation/Klingon/Romulan/Dominion Remnant fleet's victory over the Suliban at Sagittarius IX.
After the Battle of Sagittarius IX, Rear Admiral Kathryn Janeway issued an order, granting special dispensation for the Enterprise-A to retain its name and registry number. This marked the first time in history that two ships named Enterprise would be in active service at the same time.
The Enterprise was set to be scrapped in 2293. However, the hull was stolen from the breaker yards by the Motta crime family, with the yard records altered to show the ship had been disassembled on schedule. The ship became a key part of their operations over the next century.
117 years later, the USS Bajor encountered the vessel while in pursuit of Motta-affiliated Augments that had stolen the head of Lore from secure storage at Facility 4028. After Captain Kanril Eleya fired a warning shot and ordered them to heave to, the Enterprise returned fire but proved no match for the far newer Galaxy-class starship, which blew its opponent out of warp. A boarding party discovered the entire crew had been killed by inertial damper failure, and Lore and the Enterprise were secured. Starfleet Command was divided on whether to repurpose the Enterprise as a training ship or museum ship and in the meantime it was towed to 40 Eridani A Starfleet Construction Yards for repairs.

In the an alternate reality, following the destruction of the USS Enterprise in 2263, a Constitution-class vessel bearing the name and registration of the Enterprise-A was under construction at Yorktown station. (Star Trek Beyond)
