Deep Space 9 was a Federation Starbase that became one of the single most strategically, historically, and socially important outposts in the entire Milky Way Galaxy. The station was of Cardassian design, built by Bajoran slave labor between 2346 and 2351. Called Terok Nor by the Cardassians, the station was used for the processing of Uridium ore by Bajoran laborers. After the Cardassian withdrawal in 2369, the provisional government of the newly-established Republic of Bajor petitioned the United Federation of Planets for relief efforts and Federation Member status, and offered to allow the Federation Starfleet to administer the station as a starbase, prompting its new designation.


Station Layout

Deep Space Nine consists of three main areas: The central core which contains the power core, the Promenade and Ops. The Habitat ring which provides quarters for crew and visitors and is connected to the rest of the station by large bridges and the outer Docking ring (otherwise known informally as the "outer ring") which can accommodate numerous small ships and has six docking pylons to allow larger vessels to dock.

Facilities on the station include Medical D, for autopsies and the Mineral assay office. (DS9 novels: Avatar, Devil in the Sky, DS9 video game: Crossroads of Time)

Terok Nor

Double Helix: Vectors
See also Terok Nor

In the year 2366, while the station was under the command of Cardassian Gul Skrain Dukat, prefect of Bajor during the Cardassian Occupation, Terok Nor was used as a testing ground for a new variation of the Double Helix virus created by Thallonian General Gerrid Thul. The virus crossed species and affected Bajorans, Cardassians, and Ferengi.

At the behest of Bajoran doctor Kellec Ton, Dukat allowed a small contingent of Federation medical personnel, lead by Kellec's Human ex-wife, Doctor Katherine Pulaski of Starfleet, to offer aid. With the assistance of Kira Nerys, a member of the Bajoran Resistance, who found the source of the virus on the surface of Bajor, Pulaski and her team managed to find a cure for the virus before the station was destroyed by the Cardassians in order to contain outbreak. (TNG - Double Helix novel: Vectors)

When the Cardassians withdrew from Bajor in early 2369, they took every component of value from the station, destroyed what they could, and left behind only a confused Cardassian tailor, the exile Elim Garak, who was to act as the eyes and ears of the Cardassian Central Command. (DS9 novel: A Stitch in Time)

More about this era was revealed with the release of the Star Trek: Terok Nor series.

The Federation

At the request of the Bajoran Provisional Government, Starfleet took command, administering it as a Federation Starbase (even as the station remained Bajoran territory). Starfleet Commander Benjamin Sisko was made commanding officer, tasked with providing the Bajorans with the requisite help and stability to allow them to join the Federation. Sisko requested a Bajoran national as his first officer, and the post was given to Kira, now a major in the Bajoran Militia. The discovery of the Bajoran Wormhole leading to the distant Gamma Quadrant soon after turned the station into a port of call and a place of enormous scientific, strategic, and commercial importance. (DS9 episode & novelization: Emissary)

At first, Kira was opposed to the Federation's presence on DS9, but the deeply spiritual major slowly started to come around after learning that Kai Opaka Sulan believed Sisko to be the foretold Emissary of the Prophets of prophecy. (DS9 short story: "Ha'mara")

In 2370 DS9 played host to clutch of Horta eggs, they were kept in stasis, however Jake Sisko and Nog deactivated the field resulting in the eggs hatching on the station. The baby Horta proceeded to cause havoc on the station and cause massive damage before they were beamed to a new home on the passing moon The Prodigal. (DS9 novel: Devil in the Sky)

When Klingon Chancellor Gowron briefly withdrew from the Khitomer Accords in early 2372, DS9 was the site of the first battle of renewed hostility with the Klingons. (DS9 episode & novelization: The Way of the Warrior)

Later that year, the station became the focus of events when war was briefly declared between the Republic of Bajor and the Ferengi Alliance. (DS9 novel: The 34th Rule)

The Dominion War

When war with the Gamma Quadrant power known as the Dominion, which had annexed the Cardassian Union, began in late 2373, Starfleet was temporarily forced to abandon the station. But Sisko, commanding the starship USS Defiant, eventually fought his way back, liberating the station and ending the ongoing threat of Dominion occupation of Bajor. (DS9 episode & novelizations: Call to Arms..., ...Sacrifice of Angels; DS9 - Prophecy and Change short story: "Three Sides to Every Story")

Hollow Men

In 2374, just after the Romulan Star Empire entered the war against the Dominion, the station was the site of the theft of a latinum shipment. This was a small part of a huge plot by the nefarious Section 31 to create a virus that would wipe out the Founders, the shapeshifting leaders of the Dominion. (DS9 novel: Hollow Men)

In early 2375, the station was home to a research effort attempting to cure a crew of Vulcans from the effects of a Dominion Bio-weapon that was specifically designed to infect Vulcans. The cure was found through the combined efforts of Doctors Julian Bashir and Beverly Crusher, the Emergency Medical Hologram of the USS Enterprise-E, long distance assistance from Admiral Leonard McCoy, and the notes of a 22nd century Denobulan physician named Phlox. (DS9 - Tales of the Dominion War short story: "Mirror Eyes")

After the end of the war in late 2375, DS9 was the site of the signing of the official declaration of peace between the powers of the Alpha and Gamma Quadrants. Before the treaty was signed, Sisko averted an attempt to assassinate the Female Changeling who was acting as the voice for the Dominion. (DS9 novelization: What You Leave Behind; DS9 - Tales of the Dominion War short story: "Requital")

Post-Dominion War

All dates are derived from the timelines included at the beginning of Unity, and the end of Worlds of Deep Space Nine volume three


The onset of the new year found the station, now under the command of Colonel Kira Nerys, infected by the N-Vector Viroid, an agent that was created (or perhaps discovered) by Romulan scientist Mos Senay. The station was purged of the viroid, but it survived in a dormant form and may one day return. (DS9 comic: "N-Vector")

In March, upgrades began on the infrastructure of the station as well as the USS Defiant to completely replace the stations forever uncooperative Cardassian computer system with a Federation ODN network that would no longer require makeshift patches between the two systems. The upgrades also saw additions to DS9's defenses, including quantum torpedoes. Personnel were stretched throughout the upgrades as only half of the stations usual thirty-five man contingent of Starfleet Corps of Engineers personnel remained on the station following the war.

The USS Aldebaran was assigned to defend the station while it was vulnerable. In April, the station was attacked by a trio of rogue Jem'Hadar fighters who sought to erase the shame of losing the previous war by starting a new one. The Jem'Hadar were defeated, but the Aldebaran was lost with all hands and sixty-one people on DS9 were killed. Several Jem'Hadar managed to beam to the station and attempted to overload the station's fusion core. The station was saved with the assistance of the Jem'Hadar named Taran'atar, but the core had to be ejected. (DS9 novel: Avatar)

DS9's chief engineer, Nog, came upon a solution for the station's fusion core problem. With the help of the Starfleet Corps of Engineers, the abandoned Cardassian station Empok Nor was towed to the Bajor system and its fusion core transferred to DS9. (CoE eBook: Cold Fusion; DS9 - Section 31 novel: Abyss)

In May, DS9 was the center of operations in the evacuation of Europa Nova, a colony that had the misfortune of having their world contaminated by a cloud of anti-matter waste, courtesy of an Iconian Gateway and a Malon freighter in the Delta Quadrant. (DS9 - Gateways novel: Demons of Air and Darkness; DS9 - Gateways What Lay Beyond short story: "Horn and Ivory")

In late August, Bajoran First Minister Shakaar Edon was assassinated on the station's Promenade by a Joined Trill named Hiziki Gard while about to sign the paper officially inducting the Republic of Bajor into the United Federation of Planets. It was later revealed that Shakaar had been consumed by an alien Parasite, a race of sworn enemies to the Trill, who were using Shakaar for their own race's purposes. The station was subsequently locked down and quarantined. (DS9 - Mission Gamma novels: Cathedral, Lesser Evil) In early September, after the return of the USS Defiant from a three-month exploratory mission of the Gamma Quadrant, the station was cleared of the parasite threat, due in part due to the miraculous return of Captain Sisko from his stay with the Prophets.

On September 26, 2376, the crews of Deep Space Nine, past and present, attended the ceremony on Bajor that officially inducted that world into the United Federation of Planets. (DS9 novel: Unity)

On the final day of the year, Taran'atar, who was being mind-controlled by an outside source, attacked and severely injured Captain Kira and Lieutenant Ro Laren. (DS9 - Worlds of Deep Space Nine novel: The Dominion: Olympus Descending)


Shortly after the attack on Kira and Ro, Nog and Major Cenn discovered evidence implicating Intendant Kira Nerys in directing Taran'atar's actions.

In sickbay, Dr. Bashir saved Captain Kira's life by replacing her heart, which had been pierced by Taran'atar's Kar'takin, with an artificial replacement, and Dr. Tarses used an innovative technique to repair Lieutenant Ro's spine. (DS9 novel: Warpath)

The saga of Deep Space Nine will continue in Fearful Symmetry by Olivia Woods available in 2008.


Station Personnel

(A note on ranks: for the most part, all characters have the rank that they were last seen with in the post-finale 'Deep Space Nine' fiction set in early 2377, a year after the show ended.)

The stations personnel typically included a thirty-five man Starfleet Corps of Engineers team which was supplemented by nearly the same number of Bajoran Militia technicians. (DS9 novel: Avatar)

Once a Cardassian ore-processing station in orbit of Bajor known as Terok Nor, Deep Space 9 became one of the most important starbases in the Alpha Quadrant after the discovery of the Bajoran wormhole in 2369. Following the Cardassian withdrawal, ownership of the station passed to the Bajorans, operating jointly with Starfleet, under the command of Benjamin Sisko. With the discovery of the wormhole, DS9 was relocated to a position near the wormhole's mouth in the Denorios belt. (DS9: "Emissary"

After first contact was made with the Dominion, the station became the Federation's first line of defense from invasion from the Gamma Quadrant. (DS9: "The Jem'Hadar")

The station was visited by a Klingon Defense Force task force in early 2372 under the guise of joining the Starfleet forces in defending against possible invasion. In reality it was used as a staging ground to launch an invasion of the Cardassian Union, starting the Klingon-Cardassian War. The station then came directly under attack from the Klingons after Sisko sheltered the Cardassian Detepa Council. The Klingons failed to capture the council or the station thanks to the station's defenders and the eminent arrival of Starfleet reinforcements. (DS9: "Way of the Warrior")

Also in early 2372, the USS Prospect-A was authorized by Major Kira Nerys from Deep Space 9 to enter the Bajoran wormhole on a top-secret mission to recover the folded space drive prototype from the USS Rutherford. Upon her return, the heavily damaged Prospect docked at Deep Space 9. DS9 was used as a dispersal point for the Prospect's crew, with several injured crew staying behind on DS9 for medical care. The USS Tundra arrived and towed the Prospect from DS9. (Star Trek: The Prospect Chronicles: "Directive") These events take place during "Homefront" and "Paradise Lost".

DS9 was captured during the Dominion War, but liberated by Operation Return. Throughout the war, the station and wormhole were of the utmost strategic value, seen as the "key to the Alpha Quadrant." (DS9: "Call to Arms", "Sacrifice of Angels", "What You Leave Behind")

In 2376, DS9 was the site of the assassination of Natima Lang, who was running to be the premier of the new Cardassian Diet. (United Trek)

Star Trek: Pendragon

In the Pendragon timeline, Deep Space 9 was destroyed during the Federation Civil War. Having gained control of sector 001 and one-third of Starfleet, Admiral James Leyton fought his way to the Bajoran system in late 2372, and detonated the station's fusion core in order to seal the Bajoran Wormhole and prevent the Dominion from invading the Alpha Quadrant. (Star Trek: Pendragon: "Sword of Damocles", et. al)

In 2379, the Starfleet Corps of Engineers completed Project Restoration, turning the abandoned Empok Nor into a new DS9. (PDN: "Restoration")

We, the Living Dead

In We, the Living Dead, Deep Space 9 is visited by the Othello Task Force and is approached by Q, who reveals the true nature of the Q Continuum.

Set during the show's run We, the Living Dead diverges from canon into an alternate timeline.
