The '''USS ''Defiant'' (NX-74205)''' was the second [[Federation]] [[starship]] to bear the name, and the [[prototype]] of the [[Defiant class|''Defiant'' class]] of [[starship]]s.
 
   
The Defiant had been first designed in [[2366]], as a new ship to fight the threat of the [[Borg]]. The ship had been built but the receding Borg threat, numerous flaws and the fact that it almost tore itself apart during test cruises, convinced [[Starfleet]] to put the project on hold. [[Benjamin Sisko]] became involved in the project after transfering to the [[Utopia Planitia Fleet Yards]] after the destruction of the [[USS Saratoga|''Saratoga'']] at [[Wolf 359]].
+
The '''USS ''Defiant'' ([[NX]]-74205)''' was a [[24th century]] [[Federation]] {{class|Defiant}} [[starship]] operated by [[Starfleet]]. This was the first ship of the class and the second Federation ship known to bear the name ''Defiant''.
 
The Defiant was taken out of storage and assigned to [[Deep Space 9]] in early [[2371]] to protect the station from the threat of the [[Dominion]], who had destroyed the [[USS Odyssey]], a [[Galaxy class]] [[starship]], a few weeks before. The ship was granted special dispensation to install and operate a [[cloaking device]] contributed by the [[Romulan]]s. In 'payment', Starfleet would share with them all information the Defiant discovered about the Dominion on its missions into the [[Gamma Quadrant]]. The agreement also stipulated that the cloaking device was only to be used in the Gamma Quadrant. The Romulans were unsatisfied with the information the ''Defiant'' brought back but allowed the cloaking device to remain. ([[DS9]]: "[[The Search, Part I]]", "[[Visionary]]")

==History==
[[Image:Defiant DS9.jpg|200px|thumb|The USS Defiant departs Deep Space Nine.]]
+
===Origins===
Soon after its arrival at DS9, the Defiant entered the Gamma Quadrant, on a mission to open negotiations with the [[Founder]]s of the Dominion. The [[starship]] came under attack by several [[Jem'Hadar]] [[Jem'Hadar attack ship|ships]] and was boarded. The senior officers were taken to the [[Founders' homeworld]] and placed in a simulation by the [[Vorta]], [[Borath]]. Once Odo and Kira Nerys found them, the Founders allowed them to return home. ([[DS9]]: "[[The Search, Part II]]")
+
Development on the ''Defiant'' began around [[2366]] in response to the [[Borg]] threat. Although officially classified as an [[escort vessel]], the ''Defiant'' was nothing less than Starfleet's first design of [[warship]]; intended to fight, and ultimately defeat, the Borg. The vessel featured minimal equipment for scientific research and was not designed to accommodate families. ({{DS9|The Search, Part I}})
   
Several weeks later, the Defiant transported [[Jadzia Dax]] to [[Trill (planet)|Trill]] for treatment. The ship remained in [[orbit]] of Trill for several days. ([[DS9]]: "[[Equilibrium]]")
+
Launched in [[2370]], on [[stardate]] 47538.5, from the [[Antares Ship Yards]], the ''Defiant{{'}}s'' trial runs did not end well for Starfleet. The vessel was overpowered and over-gunned for a ship of its size - so much so that the ''Defiant'' nearly shook itself apart when the engines were tested at full power. Ultimately these design flaws, combined with the Borg threat becoming less urgent, led Starfleet to the decision to abandon the project and place the prototype in storage. ([[Defiant dedication plaque]]; {{DS9|The Search, Part I}})
   
When [[Major]] [[Kira Nerys]] was abducted by the [[Obsidian Order]], Sisko took the Defiant into Cardassian space. The ship's shield harmonics were reconfigured so that the ship appeared to be a [[Kobheerian]] [[freighter]]. ([[DS9]]: "[[Second Skin]]")
+
===Service at Deep Space 9===
  +
[[File:Defiant DS9.jpg|thumb|The ''Defiant'' departs Deep Space 9]]
  +
After the destruction of the {{USS|Odyssey}} in late 2370, [[Commander]] [[Benjamin Sisko]], who served on the team that designed the ''Defiant'', requested that the vessel be pulled out of storage and assigned to [[Deep Space 9]] to counter the new [[Dominion]] threat. Arriving in early [[2371]], the ''Defiant{{'}}s'' first assignment was to attempt to convince the [[Founder]]s of the Dominion that the Federation posed no threat to them. After a special amendment was made to the [[Treaty of Algeron]], the [[Romulan Star Empire]] installed one of their [[cloaking device]]s aboard the vessel to aid in its mission - in exchange for any intelligence gained on the Dominion. ({{DS9|The Search, Part I}})
   
During an exploration mission in the Gamma Quadrant the Defiant discovered the planet [[Meridian (planet)|Meridian]] on its first appearance in the primary universe since [[2311]]. ([[DS9]]: "[[Meridian (episode)|Meridian]]")
+
The mission did not go well for the DS9 crew. Shortly after entering the [[Gamma Quadrant]], the ''Defiant'' was attacked by several [[Jem'Hadar fighter]]s. During the resulting battle, the vessel was boarded and the [[senior officer]]s were captured and placed into a simulation to test how Starfleet might react to the Dominion attempting to gain a foothold in the [[Alpha Quadrant]]. Ultimately the crew was discovered by [[Bajoran Militia]] officers [[Major]] [[Kira Nerys]] and [[Odo]], and were allowed to return to DS9 with the ''Defiant''. ({{DS9|The Search, Part II}})
   
Later, the ship was stolen by members of the [[Maquis]], lead by [[Thomas Riker]], posing as his twin [[William Riker]], who used it to attack several [[Cardassian]] targets. The ship was severely threatened by several [[Obsidian Order]]'s [[Keldon class|''Keldon''-class]] warships. Having narrowly escaped, it would be protected by the [[Galor class|''Galor''-class]] warship, ''[[Kraxon]]'', until the Obsidian Order threat was nullified and for Riker to surrender to. Major Kira then took the ''Defiant'' to the Demilitarized Zone to rendezvous with another Federation starship to transfer the remainder of the Maquis for arrest. ''([[DS9]]: "[[Defiant (episode)|Defiant]]")''
+
DS9's [[chief of operations]], [[Miles O'Brien]], spent two weeks overhauling the ''Defiant{{'}}s'' [[structural integrity field]] to overcome the ships design flaws. ({{DS9|Shattered Mirror}})
   
The Defiant transported the senior staff of DS9 to [[Earth]] for a conference on the Gamma Quadrant. The Defiant was the ship chosen for a joint Federation-Cardassian-[[Bajoran]] project to send and receive messages to and from the Gamma Quadrant. ([[DS9]]: "[[Destiny]]")
+
Several weeks later, the ''Defiant'' transported [[Lieutenant]] [[Jadzia Dax]] to the [[Trill]] [[Trill (planet)|homeworld]] to receive medical treatment. ({{DS9|Equilibrium}})
[[Image:Defiant Class.jpg|200px|thumb|The Defiant in combat]]
 
   
A few months later, [[Captain]] Benjamin Sisko, acting against orders and without the cloaking device, took the Defiant into the Gamma Quadrant again to rescue [[Odo]] and [[Elim Garak]] who were on a [[Romulan]] [[warbird]] fighting the Dominion during the [[Battle of the Omarion Nebula]]. ([[DS9]]: "[[The Die is Cast]]")
+
When Major Kira was abducted by the [[Cardassian Union]]'s [[Obsidian Order]], Commander Sisko took the ''Defiant'' into [[Cardassian]] space in a rescue attempt. To ensure the Cardassians did not identify the ship, the vessel's [[shield harmonic]]s were reconfigured to make the ''Defiant'' appear to be a [[Kobheerian freighter]]. ({{DS9|Second Skin}})
   
In late 2371, the Defiant was sabotaged by a [[Founder]], who attempted to start a war between the Federation and the [[Tzenkethi]] by flying the Defiant into their space. ([[DS9]]: "[[The Adversary]]")
+
The ''Defiant'' made contact with the planet [[Meridian (planet)|Meridian]] during an exploration mission in the Gamma Quadrant. ({{DS9|Meridian}})
[[Image:Defiant_quarter_firing.jpg|200px|thumb|The Defiant opens fire]]
 
The Defiant fought its way through Cardassian space to rescued members of the Cardassian [[Detapa Council]] in [[2372]] during the [[Second Federation-Klingon War]]. ([[DS9]]: "[[The Way of the Warrior]]")
 
During a meeting with a [[Karemma]] ship the Defiant was forced into a planet's atmosphere by the [[Jem'Hadar]] where it was severely damaged and many of its crew injured. The Defiant was able to destroy the Jem'Hadar ships and rescue the Karemma. ([[DS9]]: "[[Starship Down]]")
 
The Defiant, under the command of [[Lieutenant Commander]] [[Worf]] travelled to Earth to assist Captain Sisko in suppressing a plot that would seize control of Earth from the President of the Federation. The Defiant was attacked by the [[USS Lakota]], who believed the ship's crew had been replaced by [[shapeshifter]]s. Both ships were damaged but both stood down before either could be destroyed. ([[DS9]]: "[[Paradise Lost]]")
 
   
After obtaining the detonation codes for a minefield the Klingons were deploying around the Bajoran system, the Defiant was used to detonate the entire minefield. ([[DS9]]: "[[Sons of Mogh]]")
+
Later in 2371, [[Maquis]] operative [[Thomas Riker]] hijacked the ''Defiant'' and used it to attack several Cardassian targets. Commander Sisko was forced to travel to [[Cardassia Prime]] with [[Gul]] [[Dukat]] to help track down the vessel. Although Dukat initially wanted to destroy the ''Defiant'', he agreed to release the vessel and the Maquis crew to Starfleet custody in exchange for the ''Defiant{{'}}s'' scans of the [[Orias system]] and Riker himself. After facing overwhelming opposition from Obsidian Order forces deployed from the Orias system, Riker ultimately surrendered and the ''Defiant'' was returned to DS9. ({{DS9|Defiant}})
   
Finding life difficult aboard DS9 much different to that of a starship, Worf decided to live aboard the Defiant. ([[DS9]]: "[[Bar Association]]")
+
The ''Defiant'' visited [[Earth]] later that year, where the vessel's senior staff was to attend the [[Annual Starfleet Symposium]] on the current situation in the Gamma Quadrant. ({{DS9|Past Tense, Part I}})
   
Later that year, again under of the command of Worf, the Defiant was escorting several Cardassian freighters when they were attacked by the Klingons. The Defiant accidently destroyed a Klingon civilian tranport, that was later determined to be empty and a Klingon ruse to bring Worf back to [[Qo'noS]]. ([[DS9]]: "[[Rules of Engagement]]")
+
Several weeks later, the ''Defiant'' was used to carry out a joint project between the governments of the Federation, Cardassia, and [[Bajor]] to establish communications between the Alpha and Gamma Quadrants. ({{DS9|Destiny}})
 
The Defiant later followed a rebel Jem'Hadar strike team that had attacked DS9 into the Gamma Quadrant. After rescuing more Jem'Hadar from the rebels, the two crews worked together to destroy an [[Iconian]] gateway, that the rogue Jem'Hadar had captured. ([[DS9]]: "[[To the Death]]")
 
   
Several weeks later, the Defiant took an ill Odo back to his people where he was 'judged' and changed into a solid. Elim Garak attempted to destroy the [[Great Link]] using the Defiant's weapons. He was stopped by Worf and sentenced to six months in a holding cell. ([[DS9]]: "[[Broken Link]]")
+
After a joint Obsidian Order-[[Tal Shiar]] fleet entered the Gamma Quadrant on a mission to destroy the [[Founders' homeworld]], [[Vice Admiral]] [[Toddman]] ordered that the ''Defiant'' remain at DS9 to protect the [[Bajoran sector]] from any Dominion retaliation. Despite these orders, Commander Sisko took the vessel into the Gamma Quadrant in order to rescue Odo and [[Elim Garak]], who were being held on one of the Romulan vessels in the fleet. Despite [[sabotage]] of the cloaking device by [[security chief]] [[Lieutenant Commander]] [[Michael Eddington]], the ''Defiant'' ultimately succeeded in its mission and returned to DS9. Admiral Toddman decided not to file charges against Sisko or any of the other officers who had joined him. ({{DS9|Improbable Cause|The Die is Cast}})
   
Later, the Defiant captured a Jem'Hadar ship and brought it back to the Federation for study. ([[DS9]]: "[[The Ship]]")
+
In late 2371, a [[Changeling]] posing as Federation [[ambassador]] [[Krajensky]] sent the ''Defiant'' on a patrol mission of the [[Federation-Tzenkethi border]]. During the mission, the [[Krajensky (Changeling)|Changeling]] sabotaged the ''Defiant'', causing it to fly out of control towards a Tzenkethi colony that was intended to be attacked; the Dominion hoped it would provoke a second war between the two powers. The crew was eventually able to regain control of the vessel and kill the Changeling. ({{DS9|The Adversary}})
   
Several weeks later, the Defiant was transported to the [[23rd century]], where it encountered the [[USS Enterprise (NCC-1701)|Enterprise]] and its crew on a space station near the Federation-Klingon border. The crew stopped [[Arne Darvin]], a disguised Klingon, from killing [[James T. Kirk]] with a bomb implanted in a [[tribble]]. ([[DS9]]: "[[Trials and Tribble-ations]]")
+
[[File:USS Defiant tractors Vorcha class.jpg|thumb|left|The ''Defiant'' using its [[tractor beam]]]]
  +
In early [[2372]], the ''Defiant'' fought its way through Cardassian space against [[Klingon]] forces to bring the [[Detapa Council]] to Deep Space 9, once briefly using its tractor beam as a 'substitute' shield to protect it from enemy fire when it was forced to drop its usual shields to beam the Council to safety. ({{DS9|The Way of the Warrior}})
   
While pursuing the Maquis traitor [[Michael Eddington]], the Defiant was disabled by a [[cascade virus]] that Eddington had planted in its computer systems. The ship was towed back to Deep Space Nine by the [[USS Malinche]]. After the Maquis attacked the Malinche, Sisko took the damaged Defiant after Eddington and stopped after after poisoning a Maquis planet and threatening to poison more. ([[DS9]]: "[[For the Uniform]]") Several weeks later, the Defiant destroyed a [[Danube class|runabout]] that had been stolen by a Founder and equipped with a bomb that was to be detonated in the Bajoran sun, thus destroying the entire system. ([[DS9]]: "[[By Inferno's Light]]")
+
The ''Defiant'' was used by [[Doctor]] [[Lenara Kahn]] and her research team in an attempt to create an artificial [[wormhole]]. ({{DS9|Rejoined}})
[[Image:The Defiant fighting the Borg.jpg|thumb|left|250px|The Defiant fights the Borg]]
 
When [[Deep Space Five]] detected a [[Borg cube]] on a direct course for Earth, the Defiant, under the command of Worf, joined a Starfleet [[task force]] that was assembled in the [[Typhon sector]] to stop the cube. Unsuccessful in stopping the cube at Typhon, the task force fought a running battle with the Borg to [[Earth]]. Worf was about to order a suicide run against the cube but the [[Enterprise-E]] arrived. The Defiant began to lose life support and its crew were beamed aboard the Enterprise. The Defiant crew later travelled back in time with the Enterprise crew to the year [[2063]], following a [[Borg sphere]] that had changed the timeline. After stopping the Borg, the crew travelled back to 2373. The Defiant was repaired and returned to Deep Space Nine. ([[Star Trek: First Contact]])
 
   
After a salvage operation to Empok Nor went awry, the Defiant rescued O'Brien, Nog and Garak from the station. ([[DS9]]: "[[Empok Nor (episode)|Empok Nor]]")
+
Several weeks later, the ''Defiant'' traveled to the Gamma Quadrant to meet with a [[Karemma starship]]. During the meeting, the two vessels were attacked by [[Jem'Hadar]] forces. The ''Defiant'' engaged the Jem'Hadar in the atmosphere of a [[gas giant]] and took severe damage; several of the senior officers were incapacitated. Under the command of [[Lieutenant Commander]] [[Worf]], the ''Defiant'' was able to destroy the Jem'Hadar ships and rescue the [[Karemma]]. ({{DS9|Starship Down}})
   
In late 2373, the Defiant was used to deploy a [[minefield]] near the [[Bajoran wormhole]] to stop more Dominion ships from entering the Alpha Quadrant. After a Dominion attack and takeover of DS9, the Defiant evacuated all Federation citizens from the station. ([[DS9]]: "[[Call to Arms]]")
+
In mid-2372, Commander Worf took the ''Defiant'' to Earth to assist Captain Sisko in foiling a plot by [[Admiral]] [[Leyton]] which would have overthrown the Federation government and established martial law. While on route, the ''Defiant'' was forced to engage the {{USS|Lakota}} under the command of [[Captain]] [[Erika Benteen]]; who was operating under the assumption that the ''Defiant'' was manned by Changelings. After a prolonged battle in which both ships took significant damage (it is strongly suggested by Major Kira that the ''Lakota'' was "in even worse shape" than the ''Defiant''), the ''Lakota'' eventually stood down when Benteen conferred with Worf and Kira about her orders to stop the ''Defiant''. Thus, the ''Defiant'' was allowed to continue to Earth with the evidence Sisko needed to stop the [[Coup d'état|coup]]. ({{DS9|Homefront|Paradise Lost}})
   
==The Dominion War==
+
Major Kira used the ''Defiant'' to stop the [[Klingon Empire]] from mining the Bajoran sector later that year. ({{DS9|Sons of Mogh}})
[[Image:The Defiant at Starbase 375.jpg|thumb|200px|The USS Defiant and the [[IKS Rotarran]] at Starbase 375 in 2374.]]
 
The Defiant fought valiantly throughout the [[Dominion War]] and participated in the majority of its battles.
 
   
In early 2374, the Defiant was assigned to operate out of [[Starbase 375]]. When Sisko was made [[Admiral]] [[William Ross|Ross]]' assistant, Jadzia Dax was given command of the Defiant. She commanded the ship on a mission to destroy a Dominion [[sensor array]] in the [[Argolis Cluster]]. ([[DS9]]: "[[A Time to Stand]]", "[[Behind the Lines]]")
+
The ''Defiant'' later became home to Worf, who found adapting to life on Deep Space 9 difficult. Captain Sisko gave him approval to live on the vessel so long as it did not interfere with his duties. ({{DS9|Bar Association}})
   
The ship was used in [[Operation Return]], to reclaim DS9 and stop the Dominion from the dismantling the minefield and bringing in its reinforcements from the Gamma Quadrant. After failing to stop the Dominion from destroying the minefield, the Defiant entered the wormhole in a vain attempt to stop the Dominion reinforcements. Captain Sisko convinced the [[Prophets]] to intervene and they destroyed the Dominion ships. They also made the wormhole impassable. ([[DS9]]: "[[Favor the Bold]]", "[[Sacrifice of Angels]]")
+
During an escort mission where the ''Defiant'' was protecting several [[Cardassian freighter]]s against Klingon raids, Commander Worf accidentally destroyed a [[Klingon civilian transport ship]]. The [[Klingon Empire]] requested that Worf be extradited to face justice for the ship's destruction, but was refused when it was determined that the transport ship was unmanned. ({{DS9|Rules of Engagement}})
   
Whilst en route to Gul Dukat's war crimes trial, the [[USS Honshu]] was destroyed by the Cardassians. The Defiant and the [[USS Constellation]] spent many days searching. The Defiant was about to leave the area when Dukat sent a message to the ship, informing them of Sisko's location. ([[DS9]]: "[[Waltz]]")
+
After an attack on DS9 by Jem'Hadar rebels, the ''Defiant'' pursued their vessel into the Gamma Quadrant. After rescuing the crew of a disabled Jem'Hadar fighter, the crews of the ''Defiant'' and the fighter worked together to destroy an [[Iconian gateway]] that was under the control of the rebels. ({{DS9|To the Death}})
   
Several months after the Federation retook DS9, the Defiant itself was captured by the Jem'Hadar on a scientific mission. The Defiant was reclaimed, with the help of a runabout that had been shrunk to only a few inches long. ([[DS9]]: "[[One Little Ship]]")
+
In late 2372, the ''Defiant'' took Odo to the Founder's new homeworld where he was to be judged for killing the Krajensky changeling the previous year. The [[Female Changeling]] allowed the vessel to personally transport him to the Founder's homeworld so long as one of her pilots entered the coordinates for the planet and wiped them from the ship's memory afterwards. While the vessel was in orbit, Garak unsuccessfully attempted to use the ''Defiant{{'}}s'' weapons to attack the [[Great Link]], but he was caught and prevented from doing so by Worf. ({{DS9|Broken Link}})
   
Several weeks later the Defiant rescued the survivors of its sister ship the [[USS Valiant|Valiant]], that had been destroyed by the Dominion. ([[DS9]]: "[[Valiant (episode)|Valiant]]")
+
In early [[2373]], the ''Defiant'' tractored a Jem'Hadar fighter captured by Captain Sisko back to Federation space. ({{DS9|The Ship}})
   
[[Image:Second Battle of Chin'toka 3.jpg|thumb|200px|The destruction of the ''Defiant''.]]
+
A few weeks later, Captain Sisko took the ''Defiant'' to [[Ajilon Prime]] to get his son, [[Jake Sisko|Jake]], off the front lines of the [[Federation-Klingon War (2372-73)|war with the Klingons]]. ({{DS9|Nor the Battle to the Strong}})
   
The Defiant participated in the [[First Battle of Chin'toka]]. The ship located and destroyed the power source for the [[Orbital weapon platform]], thus helping the [[Federation Alliance]] to conquer the system. ([[DS9]]: "[[Tears of the Prophets (episode)|Tears of the Prophets]]") The Defiant spent the next several months on convoy duty in the system ([[DS9]]: "[[Image in the Sand]]"). The Defiant returned to the [[Chin'toka system]] several weeks later when it made a supply run to [[AR-558]]. ([[DS9]]: "[[The Siege of AR-558]]")
+
The ''Defiant'' was later transported to the [[23rd century]], where it encountered the original {{USS|Enterprise|NCC-1701}} during its visit to [[Deep Space K-7]] in [[2268]]. The crew stopped [[Arne Darvin]] from killing [[Captain]] [[James T. Kirk]] with a bomb implanted in a dead [[Tribble]]. ({{DS9|Trials and Tribble-ations}})
   
After she was kidnapped and brought to Empok Nor, the Defiant rescued Kira and several members of the [[Pah-Wraith]] cult and brought them back to Bajor. ([[DS9]]: "[[Covenant]]")
+
The ''Defiant'' rescued Odo and [[Quark]] from an L-class planet their [[runabout]] had crashed on after being sabotaged by the [[Orion Syndicate]] ({{DS9|The Ascent}})
   
The Defiant's short but illustrious life ended during the [[Second Battle of Chin'toka]], when the ship was disabled and destroyed by the [[Breen]]'s [[energy dampening weapon]]. ([[DS9]]: "[[The Changing Face of Evil]]")
+
While pursuing Maquis-defector Michael Eddington, the ''Defiant'' was disabled by a [[cascade virus]] that Eddington had installed in the ship's computers during his time as DS9's Starfleet security chief. The vessel had to be towed back to DS9 by the {{USS|Malinche}}. When that vessel was later disabled by the Maquis, Captain Sisko used the damaged ''Defiant'' to continue pursuing Eddington. After Sisko poisoned a Maquis planet, Eddington surrendered to Sisko and was incarcerated. ({{DS9|For the Uniform}})
  +
[[File:Defiant, Borg attack 2373.jpg|thumb|left|The ''Defiant'' bridge receives heavy damage from a Borg cube]]
   
The [[USS Defiant (NCC-75633)|USS Sao Paulo]] was renamed in honor of the Defiant, and it fought in the final battle of the Dominion War, the [[Battle of Cardassia]]. ([[DS9]]: "[[The Dogs of War]]", "[[What You Leave Behind]]")
+
[[File:Defiant Borg.jpg|thumb|The ''Defiant'' fights the Borg]]
  +
Under the command of Worf, the ''Defiant'' was finally used for what she was originally designed: fighting the Borg. In the [[Battle of Sector 001]] in mid-2373, the ''Defiant'' assaulted the invading [[Borg cube]] from the [[Typhon sector]] to Earth and took severe damage. As Worf was about to order the ship to ram the cube, the {{USS|Enterprise|NCC-1701-E|-E}} rescued the vessel's survivors. The ''Defiant'' and ''Enterprise'' crews followed a [[Borg sphere]] to [[2063]] shortly after the cube's destruction to stop the Borg from sabotaging [[Zefram Cochrane]]'s first warp flight. Following these events, the ''Defiant'' was repaired and returned to DS9. ({{film|8}}; {{DS9|In Purgatory's Shadow}})
   
==First Contacts==
+
[[File:Defiant and Enterprise-E.jpg|thumb|left|The ''Defiant'' dwarfed by the ''Enterprise''-E]]
  +
When the Dominion annexed the Cardassian Union and invaded the Alpha Quadrant, the ''Defiant'' was forced to destroy the runabout {{USS|Yukon}}, which had been commandeered by a Changeling posing as [[Doctor]] [[Julian Bashir]]. The runabout was carrying a [[trilithium weapon]] which was to be detonated in the [[Bajoran sun]], destroying the entire [[Bajoran system|system]]. ({{DS9|By Inferno's Light}})
  +
  +
In late 2373, the ''Defiant'' became trapped inside a [[temporal distortion]] surrounding a planet in the Gamma Quadrant. The planet was inhabited by descendants of the ''Defiant'' crew, who revealed that the vessel would crash while attempting to escape the distortion. The ''Defiant'' crew and the planets inhabitants worked to formulate a plan that would allow the ''Defiant'' to escape back into normal space, while simultaneously creating a second ship that would crash on the planet and land 200 years in the past, thus ensuring the inhabitants survival. However, it was discovered that the plan would fail and [[Yedrin Dax]] was setting up the original ''Defiant'' to crash. The crew eventually planned to allow this event to take place, but was stopped by the elder-Odo living on the surface, who changed the ship's flight plan so that it would avoid the distortion that would send them back in time. The ''Defiant'' returned to DS9 and the colonists were found to have never existed. ({{DS9|Children of Time}})
  +
  +
===Service during the Dominion War===
  +
[[File:Defiant and Rotarran at Starbase 375.jpg|thumb|left|The ''Defiant'' and the ''Rotarran'' at Starbase 375]]
  +
In an effort to stop the Dominion's military build-up in Cardassian space, [[Starfleet Command]] opted to [[mine]] the entrance to the [[Bajoran wormhole]], a move that was virtually guaranteed to lead to [[Dominion War|war]]. Despite coming under fire by Dominion forces, the ''Defiant'' was able to successfully deploy the mine field and evacuate Deep Space 9's Starfleet personnel before the Dominion took control of the station. ({{DS9|Call to Arms}})
  +
  +
For the next several months, the ''Defiant'' fought as part of the [[Second Fleet]], operating out of [[Starbase 375]]. When Captain Sisko was made an adjutant to [[Vice Admiral]] [[William Ross]], Lt. Commander Jadzia Dax was assigned to captain the vessel. Under Dax's command, the ''Defiant'' destroyed a Dominion [[sensor array]] hidden in the [[Argolis Cluster]]. ({{DS9|A Time to Stand|Behind the Lines}})
  +
  +
Sisko returned to the [[captain's chair]] of the ''Defiant'' to lead [[Operation Return]] in mid-[[2374]]. The vessel resumed its assignment at Deep Space 9 after the station was retaken. ({{DS9|Favor the Bold|Sacrifice of Angels}})
  +
  +
The ''Defiant'' was part of a search effort to look for survivors of the {{USS|Honshu}} after the latter vessel was destroyed by Cardassian forces. Upon completion of that mission the ship was immediately assigned to escort a Federation troop convoy near the [[Badlands]]. ({{DS9|Waltz}})
  +
  +
While studying a [[subspace compression anomaly]] in mid-2374, the ''Defiant'' was taken over by Jem'Hadar forces. Thanks to the combined efforts of the ''Defiant'' crew and the {{USS|Rubicon}}, the vessel was retaken and the surviving Jem'Hadar were taken to a Federation [[prisoner of war]] camp. ({{DS9|One Little Ship}})
  +
  +
The ''Defiant'' rescued survivors from its sister ship, the {{USS|Valiant|NCC-74210}}, later that year. ({{DS9|Valiant}})
  +
  +
Upon completion of a convoy escort mission, the ''Defiant'' responded to a [[distress call]] from [[Captain]] [[Lisa Cusak]], who was commanding the {{USS|Olympia}}. The ''Olympia'' had crashed on an [[L-class]] planet in the [[Rutharian sector]] of the [[Beta Quadrant]]. Upon arrival at the planet, the ''Defiant'' crew found an [[energy barrier]] surrounding the planet which had carried Cusak's distress call forward through time; Cusak had been dead three years. Cusak's body was taken back to DS9 and a [[memorial service]] was held for her by the crew. ({{DS9|The Sound of Her Voice}})

The ''Defiant'', along with the {{IKS|Rotarran}}, led the [[Federation Alliance]] fleet at the [[First Battle of Chin'toka]] in late-2374. It was the crew of the ''Defiant'' that found a way to disable the Cardassian [[orbital weapon platform]]s protecting the [[Chin'toka system]]. ({{DS9|Tears of the Prophets}})
  +
  +
Under Worf's command, the ''Defiant'' spent the next several months on convoy duty. ({{DS9|Image in the Sand}})
  +
  +
In early-[[2375]], the ''Defiant'' made a supply run to [[AR-558]], a [[planetoid]] in the Chin'toka system under heavy siege by the Jem'Hadar. The ''Defiant'' crew provided a small reinforcement of the planetoid and helped disable the [[houdini]]s that were plaguing the Federation troops stationed there. ({{DS9|The Siege of AR-558}})
  +
  +

  +
The ''Defiant'' later served as part of a search effort to look for survivors of the {{IKS|Koraga}}, which had been destroyed by Dominion forces in the Badlands. The ''Defiant'' managed to recover six [[escape pod]]s, but was forced to call off its search for the ''Koraga{{'}}s'' captain, Worf, after only three days due to heavy Jem'Hadar patrols in the area. ({{DS9|Penumbra}})
  +
  +

  +
Later that year, the Dominion, along with their new [[Breen]] allies, retook the Chin'toka system with the [[Second Battle of Chin'toka]]. The ''Defiant'' was among the 311 ships destroyed in the battle. ({{DS9|The Changing Face of Evil}})
  +
  +
The {{USS|Sao Paulo}} was assigned to DS9 to replace the ''Defiant'' after its destruction. Captain Sisko was granted special dispensation by the [[Chief of Starfleet Operations]] to rename the ''Sao Paulo'' to ''Defiant''. ({{DS9|The Dogs of War}})
  +
  +
==Unique characteristics==
  +
===Ablative armor===
  +
[[File:Maquis raider fires on the Defiant, FTU.jpg|thumb|The Maquis attack the ''Defiant'']]
  +
The ''Defiant'' was equipped with an [[ablative armor]] coating that was designed to disintegrate under enemy fire at a controlled rate. It dissipated the effects of directed energy weapons, decreasing damage to the main hull of the ship and therefore providing an extra layer of defense. As late as [[2372]], Starfleet wasn't informed that the ''Defiant'' was equipped in that way. ({{DS9|Past Tense, Part I|The Way of the Warrior|Paradise Lost|The Changing Face of Evil}})
  +
  +
===Cloaking device===
  +
[[File:USS Defiant cloaking.jpg|thumb|left|The USS ''Defiant'' activating its cloaking device]]
  +
After the Dominion threat emerged in late-2370, a special amendment made to the Treaty of Algeron allowed the ''Defiant'' to be equipped with a Romulan cloaking device. In exchange for providing the cloaking device, the Federation agreed to share all of its Dominion intelligence with the Romulan government. Additionally, the cloak was only authorized for use in the Gamma Quadrant; although Captain Sisko violated this provision on numerous occasions. Use of the cloaking device was initially supervised by [[Subcommander]] [[T'Rul]], although the Romulans later discontinued supervision. ({{DS9|The Search, Part I|Defiant|The Way of the Warrior}})
  +
  +
Because of the amount of power the ''Defiant'' used, the cloak did not completely hide the ship from Jem'Hadar sensors during normal operation. ({{DS9|The Search, Part I}})

{{bginfo|Although {{DS9|Apocalypse Rising}} established that Worf was the first officer of the ''Defiant'' while Kira was the first officer of the station, there was some inconsistency in this arrangement. Based on {{DS9|Sons of Mogh}}, {{DS9|By Inferno's Light}}, and {{DS9|Tears of the Prophets}}, it would appear that Kira retained the first officer's position when the ''Defiant'' was operating outside of Federation space, while Worf took the position during operations inside Federation space, although this was not directly clarified on the show so it remains speculation.}}

=== Background information ===
  +
The main reason for the creation of the ''Defiant'' was that [[Ira Steven Behr]] and the writers felt that the {{class|Danube}} runabouts would not be able to protect the [[space station]] from the [[Dominion]], and that something with more muscle was necessary. In the [[DS9 Season 2|second season]] finale, {{e|The Jem'Hadar}}, the Dominion had shown themselves capable of destroying a {{class|Galaxy}} [[starship]] (the {{USS|Odyssey}}) and it was felt that viewers would not accept the idea that the [[Federation]]'s first line of defense against such a powerful enemy was three [[runabout]]s. As Behr explains, "''We had all these plans for this Dominion, not so much the [[Dominion War]] yet, but the Dominion as a three-pronged attack, and what were we going to go after them with? [[Shuttlecraft]]s? You know, I mean, with the ''Galileo'' or whatever the hell those names were? You know, it just seemed ridiculous. So we needed a ship''." Similarly, production designer [[Herman Zimmerman]] states, "''We needed a ship that would give the writers the opportunity to have more direct conflict''." (USS ''Defiant'', [[DS9 Season 3 DVD]] special features)
  +
  +
[[Ronald D. Moore]] originally wanted to call the ''Defiant'' the USS ''Valiant'', but was unable to, as the {{USS|Voyager}} also began with a "V". It was [[1998 productions|three years]] before Moore was able to name a ship ''Valiant''. The {{USS|Valiant|NCC-74210}} appears in the [[DS9 Season 6|sixth season]] episode {{e|Valiant}}.
  +
  +
[[Rick Berman]] was originally against the idea of the ship having a [[cloaking device]] because one of the tenets of [[Gene Roddenberry]]'s universe was that [[Starfleet]] "did not believe in sneaking around." However, Behr and [[Robert Hewitt Wolfe]] were able to convince Berman that the ''Defiant'' was a unique ship in a unique situation and, with the added stipulation that the cloak could only be used in the [[Gamma Quadrant]], Berman agreed. (''[[Star Trek: Deep Space Nine Companion]]'')
  +
  +
Early drafts of the script of {{film|8}} suggested that the ''Defiant'' was to be destroyed in the [[Battle of Sector 001]]. In the DVD commentary for the film, ''First Contact'' co-writer and ''Deep Space Nine'' producer Ronald D. Moore said that ''Deep Space Nine''{{'}}s Executive Producer [[Ira Steven Behr]] had seen the script and objected to the needless destruction of his ship in a story that didn't even involve the ''Deep Space Nine'' characters (apart from Worf). It would also prove to be inconvenient for the television show, so the ''Defiant'' was eventually allowed to survive the battle, and a line suggesting that the ''Defiant'' was "''adrift, but salvageable''" was added to clear up any ambiguity. No reference to the damage the ''Defiant'' received during the battle was ever made on ''Deep Space Nine'' (although a brief reference was made to the battle itself in {{e|In Purgatory's Shadow}}, when [[Benjamin Sisko|Sisko]] mentions "the recent [[Borg]] attack").
  +
  +
The {{USS|Equinox}}, a {{class|Nova}} vessel, was designed based on the design of the ''Defiant'' "Pathfinder" vehicle, registry NXP-2365WP/T, found in the ''[[Star Trek: Deep Space Nine Technical Manual]]''.
  +
  +
Models of the ''Defiant'' have been made by [[AMT/Ertl]], [[Galoob]]'s ''[[Star Trek Micro Machines]]'' range, and by [[Furuta]]. [[Corgi]] planned to release a model of the ''Defiant'' in {{y|2007}}, however this was canceled. In {{y|2008}}, the Japanese toy company [[F-Toys]] released a model of the ''Defiant'', as well as a transparent "cloaked" version.
  +
  +
The USS ''Defiant'' could be seen in the Discovery Science program ''Ultra Science'' (an episode about time travel).

An unused door signage for the ''Defiant'' was sold off on the [[It's A Wrap! sale and auction]] on eBay. {{stala|9534}}

[[Worf]]'s first mission of the computer game ''[[Star Trek: Deep Space Nine - The Fallen]]'' involves Worf being left in command of the ''Defiant'', trying to fight off a boarding party of Grigari troopers.
Early drafts of the script of [[Star Trek: First Contact]] suggested that the Defiant was to be destroyed in the [[Battle of Sector 001]]. In the DVD commentary for the film, First Contact co-writer and [[Star Trek: Deep Space Nine]] producer [[Ronald D.

In the video game ''[[Star Trek: Encounters]]'', the ''Defiant'' appears in the two levels based on [[Deep Space 9]]. In addition, the ''Defiant'' appears in the game's last level where it briefly visits an [[alternate timeline]] in which the [[Romulan Star Empire]] has conquered the [[Federation]]. The ''Defiant'' later helps the {{USS|Enterprise|NCC-1701-E|-E}}, the {{USS|Voyager}}, the {{USS|Enterprise|NCC-1701-A|-A}}, and the {{EnterpriseNX}} defeat a combined [[Xindi]], [[Klingon]], [[Romulan]], [[Dominion]], and [[Borg]] fleet.

USS Defiant

Class: Defiant-class
Registry: NX-74205
Owner: United Federation of Planets
Operator: Starfleet
Status: Destroyed (2375)
For the mirror universe counterpart, please see ISS Defiant.
"She may have flaws, but she has teeth."

The USS Defiant (NX-74205) was a 24th century Federation Defiant-class starship operated by Starfleet. This was the first ship of the class and the second Federation ship known to bear the name Defiant.

HistoryEdit

OriginsEdit

Development on the Defiant began around 2366 in response to the Borg threat. Although officially classified as an escort vessel, the Defiant was nothing less than Starfleet's first design of warship; intended to fight, and ultimately defeat, the Borg. The vessel featured minimal equipment for scientific research and was not designed to accommodate families. (DS9: "The Search, Part I")

Launched in 2370, on stardate 47538.5, from the Antares Ship Yards, the Defiant's trial runs did not end well for Starfleet. The vessel was overpowered and over-gunned for a ship of its size - so much so that the Defiant nearly shook itself apart when the engines were tested at full power. Ultimately these design flaws, combined with the Borg threat becoming less urgent, led Starfleet to the decision to abandon the project and place the prototype in storage. (Defiant dedication plaque; DS9: "The Search, Part I")

Service at Deep Space 9Edit

Defiant DS9

The Defiant departs Deep Space 9

After the destruction of the USS Odyssey in late 2370, Commander Benjamin Sisko, who served on the team that designed the Defiant, requested that the vessel be pulled out of storage and assigned to Deep Space 9 to counter the new Dominion threat. Arriving in early 2371, the Defiant's first assignment was to attempt to convince the Founders of the Dominion that the Federation posed no threat to them. After a special amendment was made to the Treaty of Algeron, the Romulan Star Empire installed one of their cloaking devices aboard the vessel to aid in its mission - in exchange for any intelligence gained on the Dominion. (DS9: "The Search, Part I")

The mission did not go well for the DS9 crew. Shortly after entering the Gamma Quadrant, the Defiant was attacked by several Jem'Hadar fighters. During the resulting battle, the vessel was boarded and the senior officers were captured and placed into a simulation to test how Starfleet might react to the Dominion attempting to gain a foothold in the Alpha Quadrant. Ultimately the crew was discovered by Bajoran Militia officers Major Kira Nerys and Odo, and were allowed to return to DS9 with the Defiant. (DS9: "The Search, Part II")

DS9's chief of operations, Miles O'Brien, spent two weeks overhauling the Defiant's structural integrity field to overcome the ships design flaws. (DS9: "Shattered Mirror")

Several weeks later, the Defiant transported Lieutenant Jadzia Dax to the Trill homeworld to receive medical treatment. (DS9: "Equilibrium")

When Major Kira was abducted by the Cardassian Union's Obsidian Order, Commander Sisko took the Defiant into Cardassian space in a rescue attempt. To ensure the Cardassians did not identify the ship, the vessel's shield harmonics were reconfigured to make the Defiant appear to be a Kobheerian freighter. (DS9: "Second Skin")

The Defiant made contact with the planet Meridian during an exploration mission in the Gamma Quadrant. (DS9: "Meridian")

Later in 2371, Maquis operative Thomas Riker hijacked the Defiant and used it to attack several Cardassian targets. Commander Sisko was forced to travel to Cardassia Prime with Gul Dukat to help track down the vessel. Although Dukat initially wanted to destroy the Defiant, he agreed to release the vessel and the Maquis crew to Starfleet custody in exchange for the Defiant's scans of the Orias system and Riker himself. After facing overwhelming opposition from Obsidian Order forces deployed from the Orias system, Riker ultimately surrendered and the Defiant was returned to DS9. (DS9: "Defiant")

The Defiant visited Earth later that year, where the vessel's senior staff was to attend the Annual Starfleet Symposium on the current situation in the Gamma Quadrant. (DS9: "Past Tense, Part I")

Several weeks later, the Defiant was used to carry out a joint project between the governments of the Federation, Cardassia, and Bajor to establish communications between the Alpha and Gamma Quadrants. (DS9: "Destiny")

After a joint Obsidian Order-Tal Shiar fleet entered the Gamma Quadrant on a mission to destroy the Founders' homeworld, Vice Admiral Toddman ordered that the Defiant remain at DS9 to protect the Bajoran sector from any Dominion retaliation. Despite these orders, Commander Sisko took the vessel into the Gamma Quadrant in order to rescue Odo and Elim Garak, who were being held on one of the Romulan vessels in the fleet. Despite sabotage of the cloaking device by security chief Lieutenant Commander Michael Eddington, the Defiant ultimately succeeded in its mission and returned to DS9. Admiral Toddman decided not to file charges against Sisko or any of the other officers who had joined him. (DS9: "Improbable Cause", "The Die is Cast")

In late 2371, a Changeling posing as Federation ambassador Krajensky sent the Defiant on a patrol mission of the Federation-Tzenkethi border. During the mission, the Changeling sabotaged the Defiant, causing it to fly out of control towards a Tzenkethi colony that was intended to be attacked; the Dominion hoped it would provoke a second war between the two powers. The crew was eventually able to regain control of the vessel and kill the Changeling. (DS9: "The Adversary")

USS Defiant tractors Vorcha class

The Defiant using its tractor beam

In early 2372, the Defiant fought its way through Cardassian space against Klingon forces to bring the Detapa Council to Deep Space 9, once briefly using its tractor beam as a 'substitute' shield to protect it from enemy fire when it was forced to drop its usual shields to beam the Council to safety. (DS9: "The Way of the Warrior")

The Defiant was used by Doctor Lenara Kahn and her research team in an attempt to create an artificial wormhole. (DS9: "Rejoined")

Several weeks later, the Defiant traveled to the Gamma Quadrant to meet with a Karemma starship. During the meeting, the two vessels were attacked by Jem'Hadar forces. The Defiant engaged the Jem'Hadar in the atmosphere of a gas giant and took severe damage; several of the senior officers were incapacitated. Under the command of Lieutenant Commander Worf, the Defiant was able to destroy the Jem'Hadar ships and rescue the Karemma. (DS9: "Starship Down")

In mid-2372, Commander Worf took the Defiant to Earth to assist Captain Sisko in foiling a plot by Admiral Leyton which would have overthrown the Federation government and established martial law. While on route, the Defiant was forced to engage the USS Lakota under the command of Captain Erika Benteen; who was operating under the assumption that the Defiant was manned by Changelings. After a prolonged battle in which both ships took significant damage (it is strongly suggested by Major Kira that the Lakota was "in even worse shape" than the Defiant), the Lakota eventually stood down when Benteen conferred with Worf and Kira about her orders to stop the Defiant. Thus, the Defiant was allowed to continue to Earth with the evidence Sisko needed to stop the coup. (DS9: "Homefront", "Paradise Lost")

Major Kira used the Defiant to stop the Klingon Empire from mining the Bajoran sector later that year. (DS9: "Sons of Mogh")

The Defiant later became home to Worf, who found adapting to life on Deep Space 9 difficult. Captain Sisko gave him approval to live on the vessel so long as it did not interfere with his duties. (DS9: "Bar Association")

During an escort mission where the Defiant was protecting several Cardassian freighters against Klingon raids, Commander Worf accidentally destroyed a Klingon civilian transport ship. The Klingon Empire requested that Worf be extradited to face justice for the ship's destruction, but was refused when it was determined that the transport ship was unmanned. (DS9: "Rules of Engagement")

After an attack on DS9 by Jem'Hadar rebels, the Defiant pursued their vessel into the Gamma Quadrant. After rescuing the crew of a disabled Jem'Hadar fighter, the crews of the Defiant and the fighter worked together to destroy an Iconian gateway that was under the control of the rebels. (DS9: "To the Death")

In late 2372, the Defiant took Odo to the Founder's new homeworld where he was to be judged for killing the Krajensky changeling the previous year. The Female Changeling allowed the vessel to personally transport him to the Founder's homeworld so long as one of her pilots entered the coordinates for the planet and wiped them from the ship's memory afterwards. While the vessel was in orbit, Garak unsuccessfully attempted to use the Defiant's weapons to attack the Great Link, but he was caught and prevented from doing so by Worf. (DS9: "Broken Link")

In early 2373, the Defiant tractored a Jem'Hadar fighter captured by Captain Sisko back to Federation space. (DS9: "The Ship")

A few weeks later, Captain Sisko took the Defiant to Ajilon Prime to get his son, Jake, off the front lines of the war with the Klingons. (DS9: "Nor the Battle to the Strong")

The Defiant was later transported to the 23rd century, where it encountered the original USS Enterprise during its visit to Deep Space K-7 in 2268. The crew stopped Arne Darvin from killing Captain James T. Kirk with a bomb implanted in a dead Tribble. (DS9: "Trials and Tribble-ations")

The Defiant rescued Odo and Quark from an L-class planet their runabout had crashed on after being sabotaged by the Orion Syndicate (DS9: "The Ascent")

While pursuing Maquis-defector Michael Eddington, the Defiant was disabled by a cascade virus that Eddington had installed in the ship's computers during his time as DS9's Starfleet security chief. The vessel had to be towed back to DS9 by the USS Malinche. When that vessel was later disabled by the Maquis, Captain Sisko used the damaged Defiant to continue pursuing Eddington. After Sisko poisoned a Maquis planet, Eddington surrendered to Sisko and was incarcerated. (DS9: "For the Uniform")

The Defiant fights the Borg

Under the command of Worf, the Defiant was finally used for what she was originally designed: fighting the Borg. In the Battle of Sector 001 in mid-2373, the Defiant assaulted the invading Borg cube from the Typhon sector to Earth and took severe damage. As Worf was about to order the ship to ram the cube, the USS Enterprise-E rescued the vessel's survivors. The Defiant and Enterprise crews followed a Borg sphere to 2063 shortly after the cube's destruction to stop the Borg from sabotaging Zefram Cochrane's first warp flight. Following these events, the Defiant was repaired and returned to DS9. (Star Trek: First Contact; DS9: "In Purgatory's Shadow")

Defiant and Enterprise-E

The Defiant dwarfed by the Enterprise-E

When the Dominion annexed the Cardassian Union and invaded the Alpha Quadrant, the Defiant was forced to destroy the runabout USS Yukon, which had been commandeered by a Changeling posing as Doctor Julian Bashir. The runabout was carrying a trilithium weapon which was to be detonated in the Bajoran sun, destroying the entire system. (DS9: "By Inferno's Light")

In late 2373, the Defiant became trapped inside a temporal distortion surrounding a planet in the Gamma Quadrant. The planet was inhabited by descendants of the Defiant crew, who revealed that the vessel would crash while attempting to escape the distortion. The Defiant crew and the planets inhabitants worked to formulate a plan that would allow the Defiant to escape back into normal space, while simultaneously creating a second ship that would crash on the planet and land 200 years in the past, thus ensuring the inhabitants survival. However, it was discovered that the plan would fail and Yedrin Dax was setting up the original Defiant to crash. The crew eventually planned to allow this event to take place, but was stopped by the elder-Odo living on the surface, who changed the ship's flight plan so that it would avoid the distortion that would send them back in time. The Defiant returned to DS9 and the colonists were found to have never existed. (DS9: "Children of Time")

Service during the Dominion WarEdit

The Defiant and the Rotarran at Starbase 375

In an effort to stop the Dominion's military build-up in Cardassian space, Starfleet Command opted to mine the entrance to the Bajoran wormhole, a move that was virtually guaranteed to lead to war. Despite coming under fire by Dominion forces, the Defiant was able to successfully deploy the mine field and evacuate Deep Space 9's Starfleet personnel before the Dominion took control of the station. (DS9: "Call to Arms")

For the next several months, the Defiant fought as part of the Second Fleet, operating out of Starbase 375. When Captain Sisko was made an adjutant to Vice Admiral William Ross, Lt. Commander Jadzia Dax was assigned to captain the vessel. Under Dax's command, the Defiant destroyed a Dominion sensor array hidden in the Argolis Cluster. (DS9: "A Time to Stand", "Behind the Lines")

Sisko returned to the captain's chair of the Defiant to lead Operation Return in mid-2374. The vessel resumed its assignment at Deep Space 9 after the station was retaken. (DS9: "Favor the Bold", "Sacrifice of Angels")

The Defiant was part of a search effort to look for survivors of the USS Honshu after the latter vessel was destroyed by Cardassian forces. Upon completion of that mission the ship was immediately assigned to escort a Federation troop convoy near the Badlands. (DS9: "Waltz")

While studying a subspace compression anomaly in mid-2374, the Defiant was taken over by Jem'Hadar forces. Thanks to the combined efforts of the Defiant crew and the USS Rubicon, the vessel was retaken and the surviving Jem'Hadar were taken to a Federation prisoner of war camp. (DS9: "One Little Ship")

The Defiant rescued survivors from its sister ship, the USS Valiant, later that year. (DS9: "Valiant")

Upon completion of a convoy escort mission, the Defiant responded to a distress call from Captain Lisa Cusak, who was commanding the USS Olympia. The Olympia had crashed on an L-class planet in the Rutharian sector of the Beta Quadrant. Upon arrival at the planet, the Defiant crew found an energy barrier surrounding the planet which had carried Cusak's distress call forward through time; Cusak had been dead three years. Cusak's body was taken back to DS9 and a memorial service was held for her by the crew. (DS9: "The Sound of Her Voice")

The Defiant fights at Chin'toka

The Defiant, along with the IKS Rotarran, led the Federation Alliance fleet at the First Battle of Chin'toka in late-2374. It was the crew of the Defiant that found a way to disable the Cardassian orbital weapon platforms protecting the Chin'toka system. (DS9: "Tears of the Prophets")

Under Worf's command, the Defiant spent the next several months on convoy duty. (DS9: "Image in the Sand")

In early-2375, the Defiant made a supply run to AR-558, a planetoid in the Chin'toka system under heavy siege by the Jem'Hadar. The Defiant crew provided a small reinforcement of the planetoid and helped disable the houdinis that were plaguing the Federation troops stationed there. (DS9: "The Siege of AR-558")

The Defiant later served as part of a search effort to look for survivors of the IKS Koraga, which had been destroyed by Dominion forces in the Badlands. The Defiant managed to recover six escape pods, but was forced to call off its search for the Koraga's captain, Worf, after only three days due to heavy Jem'Hadar patrols in the area. (DS9: "Penumbra")

The destruction of the Defiant

Later that year, the Dominion, along with their new Breen allies, retook the Chin'toka system with the Second Battle of Chin'toka. The Defiant was among the 311 ships destroyed in the battle. (DS9: "The Changing Face of Evil")

The USS Sao Paulo was assigned to DS9 to replace the Defiant after its destruction. Captain Sisko was granted special dispensation by the Chief of Starfleet Operations to rename the Sao Paulo to Defiant. (DS9: "The Dogs of War")

Unique characteristicsEdit

Ablative armorEdit

The Defiant was equipped with an ablative armor coating that was designed to disintegrate under enemy fire at a controlled rate. It dissipated the effects of directed energy weapons, decreasing damage to the main hull of the ship and therefore providing an extra layer of defense. As late as 2372, Starfleet wasn't informed that the Defiant was equipped in that way. (DS9: "Past Tense, Part I", "The Way of the Warrior", "Paradise Lost", "The Changing Face of Evil")

Cloaking deviceEdit

After the Dominion threat emerged in late-2370, a special amendment made to the Treaty of Algeron allowed the Defiant to be equipped with a Romulan cloaking device. In exchange for providing the cloaking device, the Federation agreed to share all of its Dominion intelligence with the Romulan government. Additionally, the cloak was only authorized for use in the Gamma Quadrant; although Captain Sisko violated this provision on numerous occasions. Use of the cloaking device was initially supervised by Subcommander T'Rul, although the Romulans later discontinued supervision. (DS9: "The Search, Part I", "Defiant", "The Way of the Warrior")

Because of the amount of power the Defiant used, the cloak did not completely hide the ship from Jem'Hadar sensors during normal operation. (DS9: "The Search, Part I")

First contactsEdit

Command crewEdit

The Defiant's permanent assignment at Deep Space 9 as a support vessel meant that it had no specific or dedicated crew complement. The vessel was manned by station personnel; its crew complement, as well as their assignments, often varied by mission.

Although DS9: "Apocalypse Rising" established that Worf was the first officer of the Defiant while Kira was the first officer of the station, there was some inconsistency in this arrangement. Based on DS9: "Sons of Mogh", DS9: "By Inferno's Light", and DS9: "Tears of the Prophets", it would appear that Kira retained the first officer's position when the Defiant was operating outside of Federation space, while Worf took the position during operations inside Federation space, although this was not directly clarified on the show so it remains speculation.

AppearancesEdit

The Defiant appears in all Deep Space Nine episode title sequences starting with Season 4 and beyond.

Background information Edit

The main reason for the creation of the Defiant was that Ira Steven Behr and the writers felt that the Danube-class runabouts would not be able to protect the space station from the Dominion, and that something with more muscle was necessary. In the second season finale, "The Jem'Hadar", the Dominion had shown themselves capable of destroying a Galaxy-class starship (the USS Odyssey) and it was felt that viewers would not accept the idea that the Federation's first line of defense against such a powerful enemy was three runabouts. As Behr explains, "We had all these plans for this Dominion, not so much the Dominion War yet, but the Dominion as a three-pronged attack, and what were we going to go after them with? Shuttlecrafts? You know, I mean, with the Galileo or whatever the hell those names were? You know, it just seemed ridiculous. So we needed a ship." Similarly, production designer Herman Zimmerman states, "We needed a ship that would give the writers the opportunity to have more direct conflict." (USS Defiant, DS9 Season 3 DVD special features)

Ronald D. Moore originally wanted to call the Defiant the USS Valiant, but was unable to, as the USS Voyager also began with a "V". It was three years before Moore was able to name a ship Valiant. The USS Valiant appears in the sixth season episode "Valiant".

Rick Berman was originally against the idea of the ship having a cloaking device because one of the tenets of Gene Roddenberry's universe was that Starfleet "did not believe in sneaking around." However, Behr and Robert Hewitt Wolfe were able to convince Berman that the Defiant was a unique ship in a unique situation and, with the added stipulation that the cloak could only be used in the Gamma Quadrant, Berman agreed. (Star Trek: Deep Space Nine Companion)

Early drafts of the script of Star Trek: First Contact suggested that the Defiant was to be destroyed in the Battle of Sector 001. In the DVD commentary for the film, First Contact co-writer and Deep Space Nine producer Ronald D. Moore said that Deep Space Nine's Executive Producer Ira Steven Behr had seen the script and objected to the needless destruction of his ship in a story that didn't even involve the Deep Space Nine characters (apart from Worf). It would also prove to be inconvenient for the television show, so the Defiant was eventually allowed to survive the battle, and a line suggesting that the Defiant was "adrift, but salvageable" was added to clear up any ambiguity. No reference to the damage the Defiant received during the battle was ever made on Deep Space Nine (although a brief reference was made to the battle itself in "In Purgatory's Shadow", when Sisko mentions "the recent Borg attack").

The USS Equinox, a Nova-class vessel, was designed based on the design of the Defiant "Pathfinder" vehicle, registry NXP-2365WP/T, found in the Star Trek: Deep Space Nine Technical Manual.

Models of the Defiant have been made by AMT/Ertl, Galoob's Star Trek Micro Machines range, and by Furuta. Corgi planned to release a model of the Defiant in 2007, however this was canceled. In 2008, the Japanese toy company F-Toys released a model of the Defiant, as well as a transparent "cloaked" version.

The USS Defiant could be seen in the Discovery Science program Ultra Science (an episode about time travel).

An unused door signage for the Defiant was sold off on the It's A Wrap! sale and auction on eBay. [1]

ApocryphaEdit

In the novel The 34th Rule, the Defiant has a shuttlecraft called the da Vinci.

Worf's first mission of the computer game Star Trek: Deep Space Nine - The Fallen involves Worf being left in command of the Defiant, trying to fight off a boarding party of Grigari troopers.

The Defiant, as well as the Defiant class in general, feature as playable ships in the tactical combat game Dominion Wars.

In the video game Star Trek: Encounters, the Defiant appears in the two levels based on Deep Space 9. In addition, the Defiant appears in the game's last level where it briefly visits an alternate timeline in which the Romulan Star Empire has conquered the Federation. The Defiant later helps the USS Enterprise-E, the USS Voyager, the USS Enterprise-A, and the Enterprise NX-01 defeat a combined Xindi, Klingon, Romulan, Dominion, and Borg fleet.

Also, the game Star Trek: Legacy features a mission depicting the Defiant's shakedown cruise under the command of Lieutenant Commander Benjamin Sisko. The ship encounters Romulan Tal Shiar forces preparing to ambush T'Uerell within Federation space and despite trying to evade them, is captured. The crew and the ship are rescued by a task force led by the USS Enterprise-D.
