U.S.S. DEFIANT NX-74205  

USS Defiant NX-74205 The Defiant-class Prototype Escort Starship development project began in 2366. The Defiant starship was designed to defend the Federation from a Borg invasion. However, design flaws during its shakedown cruise caused Starfleet to abandon the project. The ship was over-powered and over-gunned for a ship of its size. Cmdr. Benjamin Sisko was in charge of the Defiant development project at the Mars Utopia Planitia Fleet Yards.

In 2371, the U.S.S. Defiant NX-74205 prototype was assigned to Captain Benjamin Sisko at station Deep Space Nine to defend the Federation and Bajoran sector against the increasing Jem'Hadar and Dominion threat. The Deep Space Nine engineers under the command of Chief Miles O'Brien and Captain Sisko have since ironed out all the problems that plagued the ship. The Defiant is equipped with a Romulan D'Deridex-class Warbird cloaking device, on loan from the Romulan Empire to be used in the Gamma Quadrant, in exchange for intelligence information on the Dominion. Romulan Subcommander T'Rul supervised the installation of the cloak. The U.S.S. Defiant is the only Defiant-class starship with a cloak.

The Defiant weapons systems make it the one of the most powerful warships in Starfleet. It is outfitted with twin-pulse phaser cannons, Mark-VIII and Mark-IX photon torpedoes and Mark-X quantum torpedoes. It also employs a dual-layer ablative armor hull.

By 2374, Starfleet has at least three Defiant-class starships in service, including the U.S.S. Valiant NCC-74210. Two Defiant-class ships were sent to intercept the U.S.S. Prometheus NX-59650 when it was comandeered by Romulans in 2374.

In 2371, Captain Ramirez took the U.S.S. Valiant NCC-74210 on a training mission with 35 Starfleet Red Squad Cadets. They were to obtain technical data on a new Dominion battleship. During a skirmish with a Cardassian warship, the seven officers were killed shortly after the mission began and Captain Ramirez gave Cadet Tim Watters a field promotion before he died. Eight months later, the U.S.S. Valiant was destroyed in 2374 after Acting Captain Tim Watters attempted to destroy the Dominion battleship. The Valiant and 34 Cadets were lost. Only Cadet Dorian Collins survived, along with Jake Sisko and Ensign Nog.
