The Defiant-class is a type of Federation starship, currently employed by Starfleet.


The Defiant-class development project began in 2351 at Utopia Planitia.


The Defiant was planned to be an anti-Borg craft, with a new type of phaser technology that fired extremely short, but powerful bursts of nadion energy.

Tests of the Defiant showed that its power systems overloaded after little stress, due to the large amount of power being generated by the ship's warp core. The project was put in mothballs until the threat of the Dominion arose in 2370.
