Excelsior Class

Class Information

The Excelsior-class Starship Development Project began in 2273, with construction beginning in 2275. The U.S.S. Excelsior NX-2000 prototype was launched in 2284. The Excelsior included a prototype for the unsuccessful Transwarp Drive Development Project. The Transwarp Drive, developed by Dr. Jeffries, was Starfleet's attempt to create a new warp drive that was faster and more efficient than the current Zefram Cochrane-based design.

In 2287, during testing of transwarp drive, the Excelsior transwarp core breached and had to be ejected. The ship suffered a complete systems failure. After repairs, the Excelsior returned to Earth under impulse power. The Transwarp project was deemed a failure and the project was cancelled. The Excelsior was refit with a standard warp drive and was officially commissioned in 2290.
