USS Defiant

The USS Defiant is a Defiant class starship. There have been 2 ships of that class to bear the name:
*USS Defiant NX-74205 (prototype for Defiant class) (destroyed)
*USS Defiant NX-74205 (originally the USS Sao Paulo NCC-75633, but renamed to USS Defiant.)
The Original Defiant was brought to Deep Space 9 by Captain Benjamin Sisko for the purpose of protecting the station from the Dominion. Under the care and supervision of SPCO Miles O'brien, most of the inherent problems with the class were corrected. The Defiant, however, was destroyed in the Second Battle of Chintoka.
The second Defiant was delivered by Admiral Ross just before the final offensive of the Dominion War. Originally the USS Sao Paulo NCC-75633, it was renamed to USS Defiant NX-74205. This Defiant is still stationed at DS9 under the direct Command of Captain Kurland.
