Description Experimental starship class equipped with the latest technologies, originally constructed to fight against the Borg. After the prototype, the USS Defiant (the only Defiant class vessel to be equipped with a cloaking device), had proved to be successful in the fight against the Dominion in 2373, the series production of the class started. Due to its small size, the unequalled maneuverability and the powerful engines the Defiant class vessels are mainly used as escorts or scouts. Moreover, because of the unusually high defensive potential, they can get through almost every attack without any problems.

History
 
2366  After the Borg attack the USS Defiant is planned as an experimental prototype equipped with the newest developments in weapons and propulsion technology, in order to have better chances in case of another Borg attack.
2366-69 The USS Defiant is built in the Utopia Planitia Fleet Yards in the orbit of Mars under the supervision of Cmd. Benjamin Sisko.
2370 The USS Defiant is comissioned in the Antares Fleet Yards in the Bajor sector.
2373 After the Borg aren't a threat anymore and the USS Defiant has proved itself in the fight against the Dominion, the prototype becomes the class ship of the "Defiant class"; two additonal ships of the same type are comissioned, the USS Valiant being one of them.
