USS Defiant (NCC-75633)

The USS Defiant (NCC-75633) was one of at least three Federation starships to carry the name. The Defiant was a Defiant-class escort assigned to Deep Space 9 in the final weeks of the Dominion War. Originally commissioned as USS São Paulo, Captain Benjamin Sisko received special dispensation from Starfleet Operations to rename the ship in honor of the recently destroyed USS Defiant, which had been destroyed by Breen forces in the Second Battle of Chin'toka.

The new Defiant was slightly modified from the prototype. On the bridge, the consoles alongside the captain's chair had been redesigned, and the aft operations table replaced with a free-standing console. In addition, the ship's shield generators had been completely reconfigured, as had its internal furnishing - a fact bemoaned by Julian Bashir upon boarding the vessel.

The Defiant participated in the Battle of Cardassia, the last battle of the war. Familiar with the individual characteristics of the old Defiant, the crew found it difficult to equate the one with the other, Nog noting that the new Defiant was "a little sluggish". The vessel lacked the worn-in combat capability and effectiveness of the prototype, but acquitted herself well during the battle. (DS9: "What You Leave Behind")
