Federation starship uss defiant assigned to station Deep Space Nine.
About this creation
Designed in 2366, the Defiant was the first of what was to be a new class of heavily-armed Federation starship, and later reputed to be one of the most heavily-armed vessels in the entire Alpha Quadrant. Officially designated an escort, although unofficially a warship, the Defiant-class was specifically designed to counter the Borg. Soon after the first vessel was completed however, a combination of a less urgent Borg threat and several design flaws caused Starfleet to suspend the project. Among the flaws was the fact that the Defiant's engines were overpowered relative to the size of the ship – so much so that the Defiant nearly "tore itself apart" during its shakedown cruise.
