The Defiant-class was a type of Federation starship in use by Starfleet in the 24th century. Although officially designated as an escort, the Defiant ships were the first type of starship Starfleet ever created as a dedicated-purpose warship, and they are sometimes referred to as destroyers. (DS9 episode: "The Search"; ST video games: Armada, Armada II)

Overview

The Defiant was conceived as Starfleet's first warship in response to the many new threats faced by the Federation in the mid-24th century. The vessels were puposed as a compact design, packing a great deal of weaponry into a very small, maneuverable ship. As such, many of these vessels were fielded in battle during the Dominion War. The class has a compact warp core that produces enough energy to power a vessel four times larger than the class. (DS9 episode: "Call to Arms"; DS9 reference: Star Trek: Deep Space Nine Technical Manual; ST reference: Starship Spotter)

History

The Defiant-class was one of many new Starfleet classes developed in response to the Borg threat following Starfleet's tragic losses in the Battle of Wolf 359. The class was the first Starfleet ever developed purely as a warship, but following the Borg's early incursions the expected Borg invasion never materialized and the prototype USS Defiant spent much of its time in space dock in the Utopia Planitia Fleet Yards. Rising hostilities with the Dominion spurred the Defiant into full service, assigned to Deep Space 9 in 2371 and fitted with a Romulan cloaking device to defend the station from Dominion attack and conduct undercover operations in the Gamma Quadrant.

By the time the situation escalated into full-scale war several Defiant-class starships had been put into service and performed admirably. The original USS Defiant was destroyed by a Breen energy dampening weapon in 2375.

Following the Dominion War Starfleet developed a ship based on the lessons of the Defiant-class, the first and so far only vessel of this type, the USS Incursion is fitted with a holographic masking system and is operated by Starfleet Intelligence. (TNG video game: Away Team)

Specifications

Defiant-class vessels crewed 50 officers and crew, with room for a maximum of 150 in evacuation situations. The Defiant vessels weighed 355,000 metric tons, measured 170.68 meters in length, 134.11 meters in width and 30.1 meters in height. The Defiant had a warp core power planet rated at over 1,500 cochrane units in output, feeding two warp nacelles. The warp drive was rated for a maximum output of warp factor 9.982 for 12 hours. The ships of the Defiant class were also fitted with two impulse engine reactor plants and emitters.

The vessels have ablative armor to absorb enemy weapons fire and were fitted with beam weapons consisting of four pulse phaser cannons, capable of firing from numerous phaser arrays along the hull. Defiant ships also are equipped with two launchers, capable of firing either photorps or quantum torpedoes from numerous emplacements along the hull. In an extreme situation the Defiant-class's nose section, which contained the vessels stock of torpedoes, could be separated as a last resort to act as a large projectile.

In official and licensed sources alike, the Defiant is always listed as having four phasers and two torpedo launchers. Onscreen canon evidence has shown that these weapons can be fired from more numerous points along the hull.

The compact type-10 shuttlecraft was designed alongside the Defiant class and two can be held in the a Defiant class' shuttle bay.

In the later 24th century, the Defiant-class was slated to continue production at the ASDB Integration Facility at Antares Fleet Yards shipyards, on Antares IV. (DS9 reference: Star Trek: Deep Space Nine Technical Manual) (Star Trek: Deep Space Nine)

Background

The USS Defiant first appeared in canon in DS9 episode: "The Search".

Apocrypha

The Defiant-class was also described in unpublished works which are not included in this database as they do not fall under the qualification of "licensed Star Trek material.

The unpublished Last Unicorn Games RPG module Dominion War Sourcebook: The Fires of Armageddon mention additional ships USS Victorious (NCC-66012) and USS Nemesis (NCC-72495).

Several more previously unheard-of ships of this class were described in unused code that can be decompiled from the software of the video game Legacy. These vessels include the USS MacGoohan, USS Portmeirion, USS Drake, USS Harmony and USS Grainer.

Starfleet began developing the Defiant-class starship as a means of defense against the Borg in the wake of the massacre at Wolf 359 and near-assimilation of Earth in 2367. Starfleet abandoned the project due to design flaws, and the seemingly-decreased Borg threat.

However, when the Federation learned of the threat posed by the Dominion in 2370, the prototype USS Defiant was relaunched and assigned to station Deep Space 9, under the command of Benjamin Sisko. (DS9: "The Search, Part I")

During the Dominion War, Joran Belar, who was involved in the development of the Defiant class got the command over another prototype of the Defiant class, the USS Escort. (Star Trek: Unity One)

When the Defiant proved her value in combat against the Dominion, Starfleet commissioned other vessels of the class, many of which played decisive parts in the Dominion War and later conflicts with the Borg. (DS9: "Valiant", et. al; Star Trek: First Contact)

The experimental energy weapon NX Destructor was originally developed for the Defiant class, but only a few ships of the class were equipped with the weapon. Later on other Federation starship classes, such as the Executor-class, it became standard equipment. (Star Trek: Unity One)
