The USS Excelsior (NCC-2000) was a Federation starship in service from the late 23rd to (at least the last quarter of) the 24th century. Originally dubbed the "Great Experiment", Excelsior was the first Starfleet ship fitted with transwarp drive. Though the "experiment" apparently failed, the vessel played a role in the historic Khitomer Accords and became the prototype for Excelsior-class heavy cruisers, serving the front lines of Federation exploration and defense efforts until the end of the 24th century. (Star Trek III: The Search for Spock, Star Trek VI: The Undiscovered Country, TNG: "Interface")
- Some fans debate the apparent failure of the transwarp drive, but the Star Trek Encyclopedia mentions that the Excelsior showed different computer display graphics on the bridge in Star Trek VI, indicating that it was no longer equipped with transwarp drive.
Beginning in 2290, Excelsior was under the command of Captain Hikaru Sulu. It was then assigned to a three-year shakedown cruise, cataloguing gaseous anomalies in planetary atmospheres in the Beta Quadrant. The Excelsior design was so successful that it was put into mass production; by the 24th century, numerous Excelsior-class vessels were in Starfleet service.
On his graduation from Starfleet Academy, Luciano Mantovanni was posted to Excelsior as weapons officer, on the recommendation of James T. Kirk. (Star Trek: Liberty: "Winning the Exchange", "Rank and Privilege")
In 2311, Excelsior was under the command of Captain Nyota Uhura. Commander Saavik served as first officer, replacing the recently-KIA Commander Janice Rand. In the aftermath of the Tomed Incident, the Excelsior was recalled to Earth, but a malfunction stranded them near the Romulan border, where they encountered the USS Excelsior-C, transported back from the 2380s. During an incident in the Union system, both Excelsiors worked to preserve the timeline, fending off a bluegill invasion, and then working with Commander Liviana Charvanek to prevent the Romulan Star Empire from conquering the Federation.

TOS novel: The Fearful SummonsEdit
In this continuity, Valtane was not killed, but transferred off Excelsior by 2294. Janice Rand was only a lieutenant, serving as chief communications officer. Sencus, a Vulcan, was both executive officer and chief science officer.
At the end of 2295, Excelsior -- along with other ships of the Sixth Fleet -- was tasked with the exploration of the Beta Quadrant on a seven-year mission. ("New Order") Many of its senior staff -- including Janice Rand, Lojur and Tuvok -- requested transfers before the ship was to embark on its new mission. ("Warp Speed")
Star Trek: Hidden Frontier continuityEdit
In an alternate timeline, Excelsior disappeared into a temporal rift while en route to Khitomer in 2293. The assassination attempt on the Federation president, Ra-Ghoratreii, was successful, resulting in the Federation's obliteration of the Klingons. As punishment, the Q Continuum inflicted the Borg upon the races of the Alpha Quadrant. The crew of the 24th century dreadnought Excelsior aided Sulu's Excelsior in going back to 2293, thus repairing the timeline. (Star Trek: Hidden Frontier: "Yesterday's Excelsior")
