The U.S.S. Defiant (formerly U.S.S. Sao Paulo) is a Defiant-class escort and the successor to the prototype that was originally launched in 2370 under the command of Commander Benjamin Sisko, then-commanding officer of Deep Space 9. The prototype fought in the Dominion War and was eventually destroyed at the Second Battle of Chin'toka, after which the U.S.S. Sao Paulo was renamed and redeployed at DS9 shortly after its creation in 2375 in honor of the Defiant.
