Description Starship class of the late 23rd century deployable in many ways, which is a successor of the obsolete Constitution class. In the meantime, however, the Excelsior class itself has been used for almost one hundred years. At the beginning, the prototype of the class served as a testing platform for the transwarp project. Despite the failure of this project the series production of the Excelsior class began shortly afterwards and the class became the most successful one of the fleet. After the discontinuation of the production in the mid 24th century, there are still currently  hundreds of ships of this class, equipped with a standard warp drive, in active service, some of which have been commissioned many decades ago. Therefore, despite only moderate propulsion and defensive potential, the Excelsior class belongs to the most reliable ones in Starfleet.

History
 
2284 The Excelsior class prototype, the USS Excelsior NX-2000, is comissioned under the command of Captain Styles in the San Francisco Starfleet Yards. The ship is used as a testing platform for the transwarp project, called the "Great experiment", and equipped with a experimental transwarp drive for that purpose.
2290 After the failure of the transwarp experiment, the Excelsior is equipped with a standard warp drive and put into active service. Under the command of Captain Hikaru Sulu, the ship is ordered to a 3 years long research mission in the Beta Quadrant. Despite the failure of the original propulsion system, the Excelsior is the prototyp of hundreds of ships of this class, which are still in use in the late 24th century.
2293 With the USS Enterprise-B, a slightly modified variant of the Excelsior class is introduced. However, this variant couldn't win through against the original version, and therefore in the following period mainly the Excelsior design is used.
2350s The production of the Excelsior is discontinued. Nonetheless, due to its remarkable reliability ships, ships of this class are still in service for many decades.
