USS Nimitz (NCC-74215)

The USS Nimitz (NCC-74215) was a Federation Defiant-class starship in service during the 24th century.

The Nimitz took heavy damage in late 2374 in a Jem'Hadar attack. Lieutenant Andrea Riffin, the senior surviving officer, assumed temporary command and, with help of Richie Kennedy from the USS Baldwin, successfully repaired the ship to a point where it could safely hold off a Dominion attack and return to starbase. Andrea's leadership abilities (as well as support from her crew) led Richie to recommend her for permanent command — a move which Starfleet subsequently approved. (USS Baldwin: "Captain's View")

In 2377, the Nimitz was compromised by a computer virus an was commandeered by an unknown party, and the crew was forced to abandon ship. She was detected, and running unmanned, near Aloran IV. Richie was able to re-take her by forcing the computer to overheat, thereby shutting down the system.
