History and design

The Defiant class vessel is one of Starfleet's most advanced ship designs, conceived in response to the Borg threat. Officially, Defiant class vessels were designated "escort" ships, which Captain Sisko noted was due to Starfleet policy of not operating warships. The Unicomplex, a huge Borg complex in the Delta Quadrant. ...

Starfleet's Advanced Starship Design Bureau at the Utopia Planitia Fleet Yards began the project in 2366. Admiral Batelle Toh was responsible for the project.^{[citation needed]} Benjamin Sisko was also part of the project. After the Borg threat was deemed lower, research and production for these vessels slowed. Engineering problems – particularly in regard to the small ship's overpowered engines – led Starfleet to mothball the project. However, Starfleet put the class into production during the Dominion War. Benjamin Lafayette Sisko, played by Avery Brooks, is the main character of the television series Star Trek: Deep Space Nine. ...

The design is a semi-saucer fore and a squared-off aft. A short, rectangular extension housing the navigational deflector and an emergency matter/antimatter warhead attaches at the bow. The warp engines are housed on either side of the ship. Unusual for Starfleet vessels, the Defiant class' warp engines are not parallel; their axes intersect less than a ship-length aft of the starship. Another trait distinguishing this class is that it was specifically designed for war. Ablative hull armor, added to the design after its launch, allows Defiant class ships to take a considerable beating even after the incapacitation of its shields. The ship has few of the creature comforts that are found on most Starfleet vessels and has small racked bunk-style quarters. The infirmary is small and the design does not include science labs. The normal crew complement is forty-six personnel. The blue navigational deflector is seen here on the USS Enterprise (NCC-1701-C), an Ambassador class starship. ...

Known Defiant class starships

USS Defiant (NX-74205) 

The class pathfinder built at the Antares Fleet Yards. The Defiant is assigned to space station Deep Space Nine in 2371 to help protect the Alpha Quadrant from the growing threat from the Dominion. The Romulan Star Empire equipped the ship with a cloaking device for use on intelligence-gathering missions in the Gamma Quadrant. In addition to engaging the Dominion's Jem'Hadar, the Defiant also sees action against Breen, Cardassian and Klingon vessels. The ship is severely damaged while fighting the Borg at the Battle of Sector 001 in 2373 and is destroyed in 2375 after attempting to stop the Dominion and Breen from retaking the Chin'toka system during the Dominion War.

The Defiant retains "NX" in its registry even after the class enters mainstream production. This may be due to the continued presence of the Romulan cloaking device, a feature not shared with the Defiant's sister ships.

USS São Paulo (NCC-75633) 

Assigned to Deep Space Nine after the Defiant's destruction and rechristened as the USS Defiant. The studio did not wish to spend the time or money to redo stock effects shots of the Defiant used to depict this new vessel. As such, exterior shots of the ship include the registry number "NX-74205".

USS Valiant (NCC-74210) 

Used by Starfleet cadets of Red Squad and destroyed by the Dominion in 2374. The only survivors are Jake Sisko, Nog, and Cadet Dorian Collins (DS9: "Valiant").

• Two unnamed Defiant class ships are among the task force sent to recapture the starship Prometheus in Star Trek: Voyager's "Message in a Bottle".
• Four unidentified Defiant-class ships were among the task force that the IKS Rotarraan and the USS Defiant join following Starfleet's withdrawal from Deep Space Nine.
