The USS Defiant (NCC-1764) was a Federation Constitution-class (Bonhomme Richard sub-type) heavy cruiser in service to Starfleet in the mid-23rd century. She was the last of the original 13 Constitution-class starships to be commissioned. (FASA RPG-Federation Ship Recognition Manual)

Some sources list the Defiant's registration as NCC-1717.


Construction and Service History

Construction began on the Defiant at Tranquility Base, Luna, in the 2250s. During the early years of her service, the Defiant conducted many missions of importance for Starfleet, and constantly patrolled the Klingon Neutral Zone as tensions between the two powers continued to rise. During that time, the Defiant became the sixth Federation starship to encounter the N'shaii, and was easily able to dispatch them. (TOS novel: My Brother's Keeper: Constitution).

At sometime prior to 2265, the Defiant was refitted with new technologies, as well as receiving some cosmetic changes to the look of the ship. The USS Constellation and USS Enterprise were two other vessels that received the same treatment. (TOS novel: Crucible: The Fire and the Rose)

In late 2265, the Defiant returned from her first five-year mission, and Captain Serling stepped down as commanding officer. He was replaced by Captain Thomas Blair who took the Defiant out on her second five-year mission in early 2266. With increasing tensions with the Klingons, the Defiant was once again posted along the Neutral Zone.

By 2267, the Defiant had been assigned to operations in the Taurus Reach. That year, it accompanied the USS Endeavor (NCC-1895) and the USS Akhiel on a mission to drive Klingon forces off of Golmira, a low-tech planet where a Shedai conduit had been discovered. (VAN novel: Precipice)

In 2268, the Defiant was called to the Klingon colony on Traelus II after receiving a distress call. A landing party discovered no Klingon survivors left on the colony, but they recover a land-based web generator of Tholian origin. The Defiant set a course back for Federation space, but soon found themselves being pursued by three Tholian vessels. Trying to escape the Tholian's the Defiant entered a spatial interphase and became trapped. Captain Blair managed to get a distress call out to the USS Enterprise before the crew succumbed to madness and started to kill each other. (SCE eBooks: Interphase, Books 1 and 2)

The Defiant in the interphase

By the time the Enterprise arrived at the Defiant's location, three weeks later, the crew of the Defiant were dead, and the ship had been drawn deeper into the interphase. Interference from the Tholians stopped the Enterprise trying to retrieve the Defiant and she was left behind. (TOS episode: "The Tholian Web")

The Three USS Defiants

There are three distinct accounts of the recovery of the Defiant, the first version saw the USS Enterprise-A returning in the late 2280s and retrieving the vessel, while Interphase books one and two saw the Defiant remaining in the interphase until 2376.

The canon version shown in Star Trek: Enterprise suggests that the Defiant was transported to the Mirror Universe in 2155. Its appearance set a trend in this universe for the staple of ships named Defiant. As the Deep Space Nine episode and novel arcs have shown, throughout the 2370s.

Raise the Defiant

Raise the Defiant was a special issue of DC Comics' Star Trek line, written by Kevin Ryan and published in Winter 1994.


In 2298, the Defiant was seen drifting near the rift by the Excelsior. (TLE novel: The Sundered)

In 2376, a passing Tholian vessel rediscovered the Defiant. The USS da Vinci was sent to salvage the vessel until the Tholian vessel opened fire. The Defiant was trapped in the rift with the SCE crew. (SCE eBook: Interphase, Book 1) The Defiant was able to escape the rift to help battle against the Tholians. The Defiant later went into Spacedock on its own power. (SCE eBook: Interphase, Book 2)

In a Mirror, Darkly

The Defiant emerged in the mirror universe in the year 2155 where it was captured by the Tholians and taken to a drydock in the Vintaak system. Commander Jonathan Archer of the Terran Empire ship Enterprise learned of the ship and lead a mission to capture it from the Tholians.

With the Defiant Archer planned to use it to crush an alien rebellion plagueing the Empire, the Defiant rendezvoused the assault fleet but found only the ISS Avenger remaining. Destroying the rebels, Archer proceeded to assassinate Admiral Black and decided he was going to use the ship from the future to overthrow the Emperor. The aliens on Avenger however lead by T'Pol and Soval, inspired by the database onboard the Defiant describing a United Federation of Planets in the other universe, convinced Phlox, the only remaining non-Terran aboard Defiant, to disable the ship, allowing the Avenger to attack. However, the crew able to restore systems and destroy the rogue ship, killing Soval.

Upon the arrival of Defiant at Earth Hoshi Sato poisoned Archer and intended to use the futuristic ship to install herself as Empress. (ENT: In a Mirror, Darkly, Part II)

When Starfleet refused to surrender the Defiant was forced to engage a fleet of seven Terran vessels including the dreadnought ISS Imperator, four NX class battlecruisers, including the ISS Broadsword and ISS Khan's Wrath as well as a pair of destroyers. Despite this the Defiant was able to disable Imperator and destroy three of the NX class ships before bombarding Starfleet headquarters from orbit, eliminating Fleet Admiral Gardner, and declaring herself Empress.

Travis Mayweather was appointed the ship's Captain and over the next few months the interior and exterior appearance of the Defiant was modified to reflect the propaganda of the now Empress Sato that the ship was a vessel from the future of the mirror universe where the Terran Empire flourished into the 23rd century. The Defiant was also the subject of a massive attempt to reverse engineer it's weapon systems for installation on other Terran vessels. The Defiant was sent to the Devolin system to search for a potential rebel base, this was revealed later to be a ploy by General Shran to get the powerful ship away from Earth, leaving it vulnerable to a rebel attack. The ship later participated in the battle over Aldus Prime against rebel ships in an attempt to rescue Empress Sato.

After her successful rescue Empress Sato discussed with now regent of Vulcan T'Pol about sending the Defiant at the head of a fleet into an unexplored region of space to make contact with a race believed to inhabit the area known as Romulans. (ENT novel: Age of the Empress)

The USS Defiant (NCC-1764) was a Constitution-class heavy cruiser in operation during the 23rd century. Believed lost in 2268 as the result of an encounter with Tholians, the Defiant was actually transported into the mirror universe and captured by the Terran Empire. (TOS: "The Tholian Web", ENT: "In a Mirror, Darkly", "In a Mirror, Darkly, Part II")

USS Defiant command insignia



In 2388 during the war between the Terrans and the Alliance of Independent Governments, many of the old Imperial starships that were not destroyed by the Klingon-Cardassian Alliance were brought back into action and the Defiant once again became the Terran flagship, under command of Captain Kathryn Janeway. Ria McCarthy also served aboard the ship. (Star Trek: Pioneer (PNR): "A Mirror, Shattered")

Two years later when the Terran Empire was re-established, the ISS Defiant ceased to be the flagship and was replaced by the experimental and more advanced ISS Pioneer. (Star Trek: Pioneer (PNR): "Infinite Empires")

Defiant's registry first revealed
Remastered footage of the Defiant

No official registry was established for the Defiant during the initial run of the Star Trek television series. During the original episode "The Tholian Web", the vessel was seen from a distance which established her as a starship, a term used throughout the series to describe the USS Enterprise and other vessels of a similar configuration, later known as the Constitution class.

Oddly, Franz Joseph's Star Fleet Technical Manual did not list the Defiant. The closest entry was for the USS Defiance with the registry NCC-1717. Some believe this to be an omission or a typographical error that was never caught. Additionally, the Technical Manual lists the registry NCC-1764 as belonging to the USS Galina.

More recent, and official sources, including the Star Trek web site and Michael Okuda’s Star Trek Encyclopedia and Star Trek Chronology do list the ship as a Constitution-class vessel with the registry NCC-1764. This registry was assigned by Greg Jein, a model-maker who worked with Okuda on Star Trek: The Next Generation and the later incarnations of the Trek franchise.

The first canon appearance of the Defiant which clearly showed her registry was in the television series Star Trek: Enterprise during the episode "In a Mirror, Darkly".

It should also be noted that since the beginning of “Star Trek: Remastered”, a project produced by CBS/Paramount to bring TOS in to the 21st century with hi-definition quality video, sound and new, computer-generated special effects (CGI), the Jein registries have been consistently used when any other Constitution-class ship has been seen. As such, during the remastered version of "The Tholian Web" the Defiant's registry is clearly visible as 1764, giving further credence to the Jein list as “official” or “canon”, while simultaneously dismissing registries listed by Joseph.
