For the Kelvin timeline Enterprise, see USS Enterprise

The USS Enterprise (NCC-1701) was a Federation Constitution-class starship in service to Starfleet during the 23rd century. The vessel was commanded by seven captains, including Robert April, Christopher Pike, and the most famous of them all, James T. Kirk. When construction began on the Enterprise in 2242, the ship was designated NX-0002.

The Enterprise remained in service for forty years, engaging in numerous first contacts, military engagements, and time travel missions. She eventually gained everlasting fame during her five-year mission, under the command of Captain Kirk. Enterprise underwent a massive refit in 2270, engaged V'Ger in 2273, and self-destructed over the Genesis Planet in 2285. The Enterprise would go on to become one of the most famous Federation starships in history; so famous in fact that when Earth and Starfleet had been saved by Kirk and his crew in 2286, the Federation Council and President decided to thank them by recommissioning another Constitution-class starship, the USS Enterprise-A, and assigning them to it. The Enterprise would also be known as the Federation flagship through her service life.

Over the years, the Enterprise crew represented a wide diversity of races and cultures, including some non-humanoids and a variety of humanoid species, including Humans, Vulcans, Andorians, Tellarites, Lirin, Caitians, Betelgeusians, Kelyans, Zaranites, Saurians, Argelians, Rhaandarites, Sulamids, Triexians, Gallamites, Deltans, Tanians and even representatives of reclusive non-aligned cultures, such as a Klingon, Gorn and a Horta.

The Enterprise (NX-01).

"Enterprise" has a long and illustrious Earth lineage, from the age of sail through to the Warp 5 engine. In 1705, the British Royal Navy captured the French naval vessel l'Entreprise and renamed her HMS Enterprize, a name which was used in British and American navies through the 21st century.

In 1976, NASA launched a prototype space shuttle named Enterprise (OV-101). Several other space vessels were named Enterprise, and then in 2151, the Earth Starfleet launched their first warp 5 capable starship, christened Enterprise (NX-01). Under the command of Captain Jonathan Archer, Enterprise became a force for exploration and was fundamental in the process that led to the founding of the United Federation of Planets in 2161.

Under Captain April[]

Construction and shakedown[]

The Enterprise was the first Constitution class vessel to be authorized and construction began at Starfleet Division, San Francisco Fleet Yards, Earth on July 16, 2242. Originally proposed to be named the USS Constitution NCC 1700, due to numerous alterations in design and power it was redesignated NCC 1701. Overseeing the construction was Captain Robert April, after being appointed by Commodore van Anling, who worked closely with naval architect Lawrence Marvick, chief construction engineer Franz Joseph IV, and their team, which included Bernice Hart and Montgomery Scott. When construction began, the Enterprise had not yet been named, with the intention that the ship would be named upon completion. (TAS novelization: The Counter-Clock Incident; TOS novels: Best Destiny, Final Frontier, Vulcan's Glory)

In the EV comic: "Flesh of My Flesh", April states that he took command of the ship shortly after the completion of construction at the Utopia Plantia Yards. In the TNG video game: Echoes from the Past, the commissioning date of the Enterprise is given as in 2245.
The William Shatner TOS novel: Academy: Collision Course states that the vessel was capable of saucer separation.

Construction on the vessel proceeded well, and 2243 saw the introduction of the prototype duotronic computer system developed by Dr. Richard Daystrom. The introduction proved vital to the ship later the following year, when the half-complete ship was ordered on a top secret mission into the Romulan Neutral Zone to rescue the stricken Federation colony ship SS Rosenberg without attracting the Romulans' attention. Captain April, with the help of acting first officer, Commander George Samuel Kirk, Sr., managed to rescue the colonists, and make it back to Federation space with the help of t'Cael Zaniidor Kilyle, Field Primus of the Second Imperial Swarm, and commander of the Imperial Swarmbird ChR Raze. During this time, April chose the name Enterprise for the new ship, after being convinced to do so by George Kirk Sr. (TOS novel: Final Frontier)

During a shakedown cruise under the command of Admiral Charles Rasmussen, Klingon agents who had replaced various Starfleet Academy cadets attempted to steal the Enterprise. The plan was defeated thanks to Rasmussen, who sacrificed his life to save the ship. (TOS - Crew comic: "Shakedown")

Construction of the Enterprise was completed by early 2245, and the Enterprise was officially launched on July 4, 2245 by Federation President Samuel Solomon Qasr, and attended by former President Jonathan Archer, who had been the commander of the United Earth ship Enterprise (NX-01) nearly a century earlier. Following the launch ceremony, the Enterprise began shakedown cruises under the command of Captain April. The shakedown cruises went well and the Enterprise was finally commissioned on January 3, 2246 and began its first five-year mission of exploration. (TAS novelization: The Counter-Clock Incident; ENT episode: "In a Mirror, Darkly, Part II")

In the ST reference: Federation: The First 150 Years, the ship's launch date was April 11, 2245.

The first five-year mission[]

Under the command of Robert April the Enterprise was the first Federation ship to reach Tarsus IV in October 2246 with food and supplies for the famine-stricken colony; however, interference from the Klingon warship IKS Kut'luch meant that the Enterprise was too late to stop the execution of 4,000 colonists at the hands of Kodos the Executioner. (TOS - Enterprise Logs short story: "Though Hell Should Bar the Way", TOS novel: Captain to Captain)

In 2249, the Enterprise welcomed back George Samuel Kirk Sr. and his 16-year-old son James T. Kirk, as the starship transported them to a newly discovered archaeological site on the planet Faramond. (TOS novel: Best Destiny)

In October 2249 the Enterprise was send to investigate an apparent sudden jump in the technological capabilities of the Inhabitants of Libros III. The official records state that the Enterprise Crew had a confrontation with mysterious trans-dimensional beings who suppressed the native population which ended in a retreat and 9 crew members missing in action. (TOS novel: Captain to Captain)

Under Captain Pike[]

Enterprise Pike spacedock

The Enterprise awaits her new commanding officer.

The Enterprise returned from its first successful five-year mission in June 2251 (reference stardate 1/9506), and Captain April was promoted to commodore. April recommended that Christopher Pike, who at that time commanded the USS Yorktown, would be a logical replacement. Pike assumed command and the Enterprise embarked on another five-year mission. (FASA RPG module: The Federation; TOS novel: Vulcan's Glory; EV comic: "Flesh of My Flesh")

Two years into Pike's command, just prior to beginning a long term survey of the Pathiad Nebulatae the Enterprise's science officer was struck down with a bout of virillian toxic fever. At the recommendation of Robert April, Pike enlisted the then Cadet Spock to fill the role giving him the rank of acting ensign. (EV comic: "Flesh of My Flesh")

Spock's first few weeks on the Enterprise saw a rise in tensions among the crew as they reacted badly to his cold, logical, assessments of events, such as the recent hostage situation the Enterprise had been involved with at Reebi Station. The crew started to become more accepting to Spock following a mission to Magefferus-3 when he laid the foundation for bringing peace to the world by inspiring the inhabitants with his emotional control. (TOS comic: "Alien Spotlight: Vulcans")

Three months into Captain Pike's five-year mission, the USS Enterprise was dispatched to the Hamilton system to investigate the destruction of Starbase 18. (TOS novel: The Children of Kings)

Ngultor ship

The Enterprise in the grips of the Ngultor ship

In 2254 the Enterprise was diverted from its scheduled mission to the Marrat system to investigate some unusual activity. It soon found the culprit when it was attacked by a Ngultor ship which disabled many of the Enterprise's systems and knocked out the crew while it took it into tow to deliver to its mothership. Fortunately the crew were able to restore the Enterprise’s systems in time to break free and destroy the mothership before it consumed them. (EV comic: "Flesh of My Flesh")

Following the Ngultor incident the Enterprise proceeded to the Marrat Nebula where it drove off an attack by a local brigand on Starbase 13. It then proceeded to investigate the Pharos siteworld, above which it battled the IKS Varchas in defence of the Federation project on the planet. Pike ended the battle by destroying the siteworld. (EV comic: "The Fires of Pharos")

The Enterprise next visited Rigel VII to witness the planet's admission into the Federation. Unfortunately rogue elements began a coup and Enterprise personal were killed and injured. The Enterprise proceeded to Vega colony to make use of its advanced medical facilities. En route it answered a distress call from Talos IV and made first contact with the Talosians. Due to their ability to project illusions, Starfleet ships were forbidden to ever again visit the planet. Under General Order 7, such a visit was grounds for the only death penalty left in Starfleet. (EV comics: "Our Dearest Blood", "Nor Iron Bars a Cage"; TOS episodes: "The Cage", "The Menagerie"; WizKids module: Attack Wing)

Enterprise reentry

The Enterprise flying into Darian's atmosphere

The Enterprise was next sent to investigate the disappearance of the USS Cortez at Darien 224. It soon found that the other starship had been commandeered by a faction from an isolated colony of Vulcans on the planetoid which attacked the Enterprise. Following the battle the damaged Enterprise suffered further stresses by flying into Darien's atmosphere to rescue Enterprise personnel before the planetoid was destroyed. (EV comic: "Cloak and Dagger")

The Enterprise spent a week at Deep Space Station K-12 undergoing repairs. While there Pike took a shuttle to Earth after being informed his father was unwell. The message was a fake sent by the Commander Kaaj of the IKS Varchas, seeking revenge for his shaming in the Marrat nebula. Fortunately the Enterprise crew were able to uncover the scheme and drive off the Varchas before the Klingons were able to kill Pike. (EV comic: "The Flat, Gold Forever")

The Enterprise next visited Neyda Prime and Liria before battling a Chakuun Ghostship which had attacked Jubal. The Enterprise limped home to Earth for repairs and then headed a task force to defend Federation colonies along the Tholian border from further Chakuun attacks. (EV comics: "Immortal Wounds", "One of a Kind", "The Fallen")

The task force soon saw action in defence of Theta Kalyb where four of the other ships in the force were destroyed before the Chakuun retreated. The Enterprise and the only other surviving vessel, the USS Nelson, went to Starbase 45 to undergo repairs. (EV comic: "The Fallen")

While the Enterprise was still in spacedock Robert April temporarily retook command while Pike was sent on a top secret mission to Temazi. The Enterprise was also sent to Temazi shortly after where it battled a pair of Klingon D7 class vessels in orbit. (EV comics: "Futures", "Thanatos", "Nemesis")

During the Federation-Klingon War of 2256-57 the Enterprise was ordered to continue its five year mission and remain away from the front lines as Starfleet intended the ship and her crew to be a weapon of last resort. Being forced to remain away from the front lines took a toll on all of the ship's crew. (DSC episode: "Brother")

In around April 2256, Enterprise was sent to investigate the disappearance of a number of civilian ships in the Pergamum Nebula. The objective was to survey the mostly unknown region for an entire year. When hostilities with the Klingon Empire escalated to a war, Enterprise was ordered to stay put. After a short confrontation with the Pirate ship Deathstrike, Enterprise began am expedition of the polar regions of the planet Susquatane. The planetary expedtion sites were attacked by then unknown enemies in the last days of 2256. All thirty members of the expedition where assumed dead by Enterpriseʼ crew. In actuality the thirty crewmembers were forcefully recruited by the Boundless: A warring fraction operating in the pergamum. In April 2257 Enterprise got involved into a conflict between the boundless and the Rengru. During the attack, Enterpriseʼ crew was separated as a consequence of a saucer separation. While the saucer crashed upside down on a the icy planet Defoe, the engineering section under the command of Number One started to investigate the Rengru. After they successfully established contact with the Rangru, Enterprise was re-united around May 2257. After Enterprise diplomatically ended the conflict between the boundless and the rangru, she returned heavily damaged to Earth. (DSC novel: The Enterprise War)

Enterprise Discovery

Federation starships Enterprise and Discovery.

Shortly after the end of the war with the Klingons, the Enterprise suffered a catastrophic systems failure while on her way to investigate red bursts that had appeared throughout the galaxy. This systems failure forced Captain Pike to send out a priority one distress call. The USS Discovery responded to the distress call and rendezvoused with the Enterprise. (DSC episodes: "Will You Take My Hand?", "Brother")

Captain Pike was named the temporary commanding officer of Discovery to investigate the red bursts while Starfleet made preparations to have Enterprise towed back to spacedock for repairs. (DSC episode: "Brother")

After the necessary repairs, the Enterprise continued its exploration mission under Captain Christopher Pike's command. Their initial destination was a newly discovered moon located at Edrin II. (DSC episode: "Such Sweet Sorrow, Part 2")

After completing their mission on Edrin II, the crew of the Enterprise returned to Earth for a short downtime. In 2259, while the Enterprise was undergoing scheduled maintenance, Admiral Robert April called upon Captain Pike and ordered the ship out of drydock. This was prompted by the disappearance of Una Chin-Riley and the USS Archer during their first contact mission to Kiley 279, which involved a violation of General Order 1. As a result of this incident, Starfleet Command renamed it to the Prime Directive. As the Enterprise resumed its duties, Pike invited La'an Noonien-Singh, his temporary first officer during Una's absence, to join as the new security chief. (SNW episode: "Strange New Worlds")

As part of its mission, the Enterprise made its first stop to observe a planet located in the Persephone system. While endeavoring to divert a comet, an unexpected altercation ensued with a species known as the Shepards. (SNW episode: "Children of the Comet")

In order to investigate the fate of missing individuals, the Enterprise ventured to Hetemit IX, an abandoned Illyrian colony. However, an outbreak of an Illyrian virus occurred on the ship, causing the crew to uncontrollably crave light, leading Number One to place the crew on lockdown. La'an's sickness nearly caused to initiate a warp core breach before Christine Chapel was able to synthesize antibodies to the virus based on La'an's proximity to Number One's Illyrian immune system. (SNW episode: "Ghosts of Illyria")

In a subsequent encounter, the Enterprise found itself facing a small fleet of Gorn vessels at Finibus III. The ship endured substantial damage to its hull, torpedo bay, and structural integrity field, narrowly escaping from the skirmish. (SNW episode: "Memento Mori")

Following the altercation with the Gorn, the Enterprise made a visit to Starbase 1 for necessary repairs. While the crew enjoyed shore leave, Captain Pike engaged in negotiations with the R'ongovian Protectorate. (SNW episode: "Spock Amok")

Later, the Enterprise came across a distressed shuttlecraft under attack by presumed pirates. The ship provided assistance, safely returning the occupants to their planet. Subsequently, the crew delved into the investigation of the wreckage to uncover the motives behind the pirates' actions. (SNW episode: "Lift Us Where Suffering Cannot Reach")

In a turn of events, the Enterprise faced a hijacking by a group of rogue pirates, facilitated by a treacherous passenger. However, through clever tactics, the crew managed to outsmart the pirates and gain control of one of their ships, ultimately reclaiming the Enterprise. This was accomplished by disabling the warp and impulse engines of the hijacked vessel. (SNW episode: "The Serene Squall")

In 2259 was send to investigate the disappearance of Braidwood, a civilian starship that was used for an anthropological expedition, in the Bullseye nebula. (SNW novel: The High Country)

Accompanied by the USS Cayuga the Enterprise later, made a visit to the Neutral Zone to assist in retrofitting the Earth Outpost Stations and delivering essential supplies. Shortly thereafter, Commander Chin-Riley was arrested upon the revelation of her true identity as an Illyrian. (SNW novel: A Quality of Mercy)

Enterprise returned to Earth for several weeks in 2261. Improvements were installed that took at least 7 weeks. (TOS novel: Inception)

In 2262, the Enterprise entered spacedock for an extensive refit, which completed two years later. (TOS novel: Where Sea Meets Sky)

First Missions under Captain Kirk[]

For a complete chronology of the Enterprise's activities in this period see: The Voyages of the USS Enterprise (NCC-1701) (2264 to 2270).

Enterprise in the late 2260s.

In 2264, command of the Enterprise was passed on to James T. Kirk, the youngest captain at that time, when by Pike was promoted to fleet captain and assigned overall control of Constitution-class starship operations. (TOS novel: Enterprise: The First Adventure; FASA RPG module: The Federation)

The Enterprise's first mission under Kirk wasn't a deep-space exploratory mission or a mission of importance, but to transport the Warp-Speed Classic Vaudeville Company around the Federation Phalanx to Starbase 13. Although Kirk was very reluctant to this first assignment, Admiral Kimitake Noguchi, though he needed the time to work out his command, and ordered him to do it or lose the Enterprise. The voyage was far from uneventful, however, after encountering the rebel Klingon Bird-of-Prey Quundar, and encountering a generational vessel. (TOS novel: Enterprise: The First Adventure)

The first Mission under Captain Kirk in 2265 was a delivery of medical supplies to Draxis II. Next Enterprise was sent to a diplomatic mission to Karabos II. The planet was to be terraformed by the Aulacri. The Aulacri terraforming project would have destroyed significant archaeological sites on the surface. It turned out the artefacts belong to the ancient Aulacri and thus it was decided to delay the terraforming project. (TOS novel: The Captain's Oath)

The USS Enterprise Owners' Workshop Manual reference book gives 2263 as the year in which Kirk was given command of the ship.

The ship was than dispatched to Aldebaran III to pick up personal and sensor equipment for the following mission to the recently discovered Galactic barrier. (TOS novel: The Captain's Oath, TOS episode: "Where No Man Has Gone Before")

Accordion to The Captain's Oath, the Mission to the galactic barrier and the events of Where No Man Has Gone Before are not part of the regular five-year-mission

Kirk's five-year mission[]

Following several other adventures, the Enterprise was finally dispatched on a five-year mission, in which the ship's primary mission was to seek out and contact alien lifeforms. Beyond this primary mission, the Enterprise was also charged with defending Federation territory from aggression, aid member worlds in crisis, and provide support for scientific expeditions and colonies that were working in the Enterprise's patrol area. (TOS episodes: "Balance of Terror", "The Cloud Minders", "Journey to Babel", "The Deadly Years", "The Man Trap")


Spock melding with Horta

Spock makes contact with a Horta.

Over the course of the five-year mission, the Enterprise visited many different planets and encountered representatives from dozens of different species. On many occasions the Enterprise made first contact with beings that hadn't been encountered by the Federation before, including stellar neighbors, voyagers from outside the Milky Way, and powerful non-corporeal entities.

List of first contacts[]

The galactic barrier[]

Galactic Barrier

The Enterprise escapes from the galactic barrier.

A short time into the five-year mission in 2265 (stardate 1312.4), the Enterprise was ordered to probe beyond the edge of the galaxy by Admiral Saylor. Upon arriving at the edge the Enterprise collided with the previously-undocumented galactic barrier, which critically damaged various ship's systems and killed nine crewmembers. Two further crewmembers, Elizabeth Dehner and Gary Mitchell, died as a result of the strange unusual energy which enhanced their ESP senses. Lieutenant Lee Kelso was also killed by Mitchell while on the surface of Delta Vega. (TOS episode: "Where No Man Has Gone Before"; TOS novels: Republic, Constitution)

The Enterprise was forced to return to the barrier in 2268 when she had been taken over by the Kelvans and upgraded with Kelvan technology so that she was able to cross the barrier safely and head for the Andromeda Galaxy. (TOS episode: "By Any Other Name") Some months later, the Enterprise once again breached the barrier and became trapped in the void just beyond it. (TOS episode: "Is There in Truth No Beauty?")

Time travel[]

The reality of externally influenced time travel had been well known and documented since the voyages of the Enterprise (NX-01) in the 2150s, yet this Enterprise became the first Federation starship to experience deliberately-controlled time travel.

The development of time travel came by accident in 2266 when the Enterprise was observing the break-up of planet Psi 2000. The crew had been struck down by a polywater intoxication and one crewmember had shut down the ship's engines and the Enterprise was quickly losing orbit. With no other choice, Lieutenant Commanders' Spock and Montgomery Scott performed a "cold start" of the warp engines via a controlled matter-antimatter implosion which saved the ship but also sent the Enterprise into a time-warp as it escaped the planet's gravity well and sent her back three days into the past. (TOS episode: "The Naked Time"; TOS - The Janus Gate novel: Present Tense)

The following year, the Enterprise was hurled through space and time to Earth in 1969 while attempting to escape the gravitational pull of a black star. The Enterprise crew were able to engineer their return to the 23rd century by warping around Sol's gravity well in a slingshot maneuver. (TOS episode: "Tomorrow is Yesterday") Subsequent research confirmed that their previous cold start had contributed to a chain of events that caused subtle changes to the Enterprise's engines compared to other Constitution-class ships, with the result that only the Enterprise could perform a slingshot maneuver at this time (DTI: Forgotten History).

The following year, Starfleet Command ordered the Enterprise to use the proven slingshot method and returned to Earth in 1968 to perform an historical observation mission. (TOS episode: "Assignment: Earth")

Spaceborne entities[]

Planet killer fires antiproton beam, remastered

The "doomsday machine" fires its antiproton beam.

Some discoveries made by the Enterprise during the five-year mission included confrontations with entities and mechanisms which threatened great areas of Federation space.

In 2267, the Enterprise encountered an ancient "doomsday machine", which destroyed objects using an antiproton beam and then consumed them. Because the object was heading through the most densely inhabited areas of the Federation including the Rigel star system, the Enterprise was forced to shut down the machine with the help of the stricken USS Constellation, a former victim of the machine. (TOS episode: "The Doomsday Machine"; TNG novels: Vendetta, Before Dishonor)


The Enterprise approaches a giant space amoeba.

The following year, a giant space amoeba emitted a negative energy which was toxic for humanoid life and had claimed the lives of the Vulcan crew of the USS Intrepid. The Enterprise responded to the Intrepid's distress call and was able to penetrate the cell interior and set off an antimatter explosion which destroyed the amoeba before it was able to divide. (TOS episode: "The Immunity Syndrome")

From late 2269 to mid-2271, the Enterprise was given several "make-overs". Over these years, she had an extra bridge turbolift added; a domed, navigational dish mounted to the bridge ceiling; an early version of a holodeck; an inflatible decoy releasing system; and additional decks. (TAS episode: "The Practical Joker") During this same year, Enterprise was dispatched to investigate a huge cosmic cloud that was approaching the planet Mantilles in the Pallas 14 system. Upon arrival in the system, the Enterprise crew observed the cloud consuming the planet Alondra and then continue to Mantilles. With no choice but to try and stop the cloud, Captain Kirk took the Enterprise into the cloud to find a means of slowing it down. Thankfully, Spock was able to mind-meld with the cloud and divert it from Mantilles at the last possible moment. (TAS episode: "One of Our Planets Is Missing")


On stardate 1512.2, Kirk managed to prevent Commander Balok of the First Federation vessel Fesarius from destroying the Enterprise after he bluffed Balok into believing that the Enterprise was equipped with a corbomite device. This tactic again proved useful in 2267 when facing the Romulans. (TOS episodes: "The Corbomite Maneuver", "The Deadly Years"; WizKids module: Attack Wing)

Klingon engagements[]

USS Enterprise-D7 face off

The Enterprise is confronted by a fleet of D7-class battlecruisers.

Throughout the five-year mission, the warships of the Klingon Imperial Fleet became a constant opponent of the Enterprise. While high-ranking officers such as Commander Kor relished the prospect of battle against Kirk and the Enterprise, lower ranks chose to mock the starship and her commanding officer. (TOS episodes: "Errand of Mercy", "The Trouble with Tribbles")

Following the outbreak of the First Federation-Klingon War in 2267, the Enterprise was immediately attacked by the IKS Vortha, which the Enterprise was easily able to dispatch. (ST - Klingons - Blood Will Tell comic: "Against Their Nature")

After the battle with the Vortha, the Enterprise was ordered to proceed to Organia in an attempt to secure the region. Unfortunately, a large Klingon invasion fleet led by Kor entered the system and forced the Enterprise to leave, with Kirk and Spock trapped on the surface. The Enterprise later returned with a Starfleet force and prepared to engage Kor's fleet but the fighting was stopped by the Organians and the Organian Peace Treaty was imposed. (TOS episode: "Errand of Mercy"; ST - Klingons - Blood Will Tell comic: "Against Their Nature")

A few months later, a D7-class warship attempted to keep the Enterprise clear of Capella IV while Klingon agents were on the planet trying to subvert the natives and gain access to the planet's topaline. While the plan was unsuccessful, the warship's crew later engaged Enterprise security personnel and Capellan warrior's in a pitched battle on the surface of Capella IV. The battle was only concluded when Klingon General Kellen negotiated the Enterprise's assistance in engaging the Furies. (TOS episode: "Friday's Child"; TOS novel: First Strike)

The following year, the Enterprise was sabotaged by a Klingon agent who had infiltrated the Dohlman of Elas' entourage during a diplomatic mission in the Tellun system. The Enterprise was then attacked by a D7-class battle cruiser, but was able to escape with the Dohlman's assistance. (TOS episode: "Elaan of Troyius")

A few months later, the Enterprise was forced to destroy the abandoned IKS Voh'tahk, under the command of Commander Kang, as the radiation emitted from the ship posed a hazard. The surviving Klingons were beamed aboard the Enterprise, and later launched an attempt to gain control of the Enterprise under the influence of the Beta XII-A entity. (TOS episode: "Day of the Dove"; ST - Klingons - Blood Will Tell comic: "Issue 4")

In 2270, the Enterprise was engaged by a group of Klingon vessels led by the IKS Worvig, a 25-century Somraw-class Raptor escort that had come back in time to destroy the Enterprise and change history in favor of the Klingon Empire. The Enterprise was rescued by a 25th-century Starfleet vessel that had traveled back from the year 2409 in pursuit of the Worvig. The Enterprise then returned the favor by defending the future Starfleet vessel from additional Klingon attack until the other vessel could return to their own time. (STO mission: "Past Imperfect")

Romulan engagements[]


The ChR Gal Gath'thong in 2266

In late 2266 the Romulan Star Empire re-emerged from a century of isolation and dispatched the ChR Gal Gath'thong to cross the Romulan Neutral Zone and attack several Earth outposts. The Enterprise was the first vessel to respond to the outposts' distress call and engaged the Gal Gath'thong. During the engagement, the Romulans powerful plasma torpedoes caused significant damage to the Enterprise, and their cloaking device made it difficult for the starship to detect them. Fortunately, the Enterprise was able to overcome the Gal Gath'thong before it returned to Romulan space. (TOS episode: "Balance of Terror"; In early [; WizKids module: Tactics)

The following year, a fleet of ten Vas Hatham-class birds-of-prey engaged the Enterprise when it crossed into the Neutral Zone in order to take a direct route to Starbase 10. The unfortunate action was taken by Commodore George Stocker who was in temporary command while Captain Kirk was incapacitated. Thankfully, Kirk was able to recover and once again used his corbomite bluff to fool the Romulans and escape back to Federation space. (TOS episode: "The Deadly Years"; TOS comic: "The Final Voyage"; WizKids module: Tactics)

In early 2268 the Enterprise was ordered to cross into the Romulan Neutral Zone as part of Operation Purloin, an operation to capture a cloaking device that had been devised by Starfleet Intelligence. Shortly after crossing, the Enterprise was surrounded by three Stormbird-class battlecruisers, commanded by Commander Charvanek, and Captain Kirk and Commander Spock were taken prisoner. Kirk and Spock were eventually able to steal the cloak from Charvenak's flagship, the ChR Memenda, and made it back to the Enterprise with Charvanek as a prisoner. Eventually, Montgomery Scott was able to connect the cloak to the Enterprise's systems and she escaped back to Federation space. (TOS episode: "The Enterprise Incident"; FASA RPG module: The Federation; TOS novel: Swordhunt)


Service aboard the Enterprise proved to be hazardous, especially for those crewmembers serving in the security division. The first crewmember to be killed during Captain Kirk's first tenure in command of the Enterprise was communications officer Hounslaw Tanaka. (ST novel: Captain's Peril)

By the end of the five-year mission, ninety-four crewmembers had met violent deaths. (TOS novelization: The Motion Picture)

Refit and further service[]

For a complete chronology of the Enterprise's activities in this period see: The Continuing Voyages of the USS Enterprise (NCC-1701).

In 2270, following the completion of Kirk's historic five-year mission, the Enterprise returned to Earth. Originally the ship was going to be decommissioned and dismantled after returning to Earth, but the high profile nature of the Enterprise and her crew led Starfleet to reverse that decision.

However, the Enterprise was still 25 years old by 2270. Despite undergoing several refits over the years, it became apparent that the technology on the ship was becoming outdated, and that a major refitting of the Enterprise would be required. During the final days of Kirk's historic five year mission, new warp technology was being perfected, and Starfleet's Corps of Engineers decided that the Enterprise would be an ideal test-bed for the new technology. This decision was also encouraged by Commodore Antonio Delgado, who was interested in the ship's slingshot-capable engines as part of his own efforts to properly research time travel. When the ship arrived at Earth, she was put into dry dock for this major refit, which would take eighteen months to complete. (TOS movie, novelization & comic adaptation: The Motion Picture)

The original warp nacelles were replaced with newer and larger units, with Delgado and the newly-formed Department of Temporal Investigations discreetly taking 'custody' of the engines to create Timeship One (DTI: Forgotten History). When it was found that the original pylons would not support the weight of the new nacelles, nor would they be large enough to house the plasma transfer conduits, they were also replaced. A new matter/anti-matter reactor was placed in the secondary hull. The impulse engine deck at the rear of the primary hull was switched out during the refit.

The exterior navigational deflector was replaced with an internal unit, and a new photon torpedo launching system was added to the connector between the primary and secondary hulls. This updated torpedo deployment method channeled propulsion directly from the matter/antimatter intermix. The bridge module was replaced with a new unit, and the original bridge module was taken and placed on board the USS Yorktown. (TNG novel: Crossover, novelization : "Relics")

Docking ports were added at various points to allow secondary craft - such as shuttlecraft and travel pods - to dock with the Enterprise without needing to enter the shuttle bay.

When it was found that the main computer would not be powerful enough to handle the new technology - especially the new warp systems, it was replaced. During the course of the refit, Romulan spies managed to infect the new computer systems with a Trojan Horse virus, which was discovered and removed from the computer systems just before the ship launched. It was operated by Mark VII multitronic software. (TOS short story: "Night Whispers")

As the refit of Enterprise neared completion, Starfleet decided not to paint the hull with the customary thermocoat that had been applied to vessels previously. Engineers offered to paint the hull of the Enterprise following the final outfitting, but Admiral Kirk declined, preferring the appearance of the Enterprise without the thermocoat. In fact, on the whole this new look was so favorably received that Starfleet eliminated thermocoats from all ships displacing 90,000 metric tons and above. (TOS reference: Mr. Scott's Guide to the Enterprise)

Command of the ship during the refit was given to Captain Willard Decker, who remained with the Enterprise throughout the entire refit process. (TOS reference: Mr. Scott's Guide to the Enterprise; "Enterprise Logs"; TOS novel: Ex Machina)

Another five-year mission[]

1701 Refit

The Enterprise during her 2273-2278 five year mission

Captain Decker was slated to retain the command of the Enterprise upon the ship's relaunch; however, then-Admiral Kirk assumed command in response to the crisis involving the machine entity "V'Ger." Because Decker had become intimately familiar with the redesigned Enterprise, Decker remained on board as Kirk's executive officer. Decker was reported missing in action during that mission, and Kirk resumed permanent command of the Enterprise. (TOS comic: "The Final Voyage"; TOS novel: The Lost Years; TOS movie, novelization & comic adaptation: The Motion Picture)

Immediately after the crisis with V'Ger the Enterprise stopped at a starbase for final outfitting, which included components that had been left out due to the emergency nature of the launch of the refitted Enterprise. One of the minor items fixed during this layover was the inclusion of an image of the Enterprise NX-01 in the recreation room display of past vessels named Enterprise. The starbase crew offered to paint the Enterprise, but Kirk declined, preferring the hull unpainted. (TOS novel: Ex Machina)

Captain Kirk decided to recommend that the science station be returned to its previous location instead of being behind the Captain's chair. At some point prior to 2283 this was done. (TOS novel: Ex Machina)

One of the first missions of the refitted Enterprise was to travel to Lorina when strife broke out amongst the descendants of the Fabrini. (TOS novel: Ex Machina)

In 2273, the Enterprise went to the planet, Cragon V. The Enterprise was disabled with the IKS Ghargh by the planet’s ruler, Weyland. Three Enterprise crewmembers were sent back into time by Weyland. Captain Kirk was able to show that the Federation was honorable and good, and the Enterprise crewmembers were returned. The Enterprise was able to help Commander Kral regain his vessel and the Enterprise was returned to normal by Weyland. The Enterprise went to Starbase 42, afterwards. (TOS novel: Home Is the Hunter)

In 2278, the Enterprise stopped at Starbase 18 to pick up supplies to bring to Vestra V. After re-supplying the colony, the Enterprise went to planet Akkalla to retrieve a science team. The crew of the Enterprise helped discover the true origins of the Akkallan people and stopped the Chorymi from harvesting the Akkallan oceans. The Enterprise went to Earth afterwards. (TOS novel: Deep Domain)

Training ship[]

In 2284, Enterprise was retired from active service, and assigned to Starfleet Academy as a training ship. (TNG video game: Echoes from the Past; WizKids module: Attack Wing)

The ship was reactivated by Admiral Kirk in response to a crisis involving Project Genesis. The Enterprise soon encountered the USS Reliant, which refused to answer hails as she approached. Even though regulations called for Kirk to assume a defensive posture when the Reliant didn't answer their hails, Kirk ignored the regulation. When the Reliant pulled up alongside the Enterprise, the Reliant opened fire, severely damaging the engineering section.

It was then that Khan revealed himself. Kirk was able to use the Enterprise computer to lower Khan's shields, damaging the Reliant enough to drive her off. The Enterprise and Reliant faced off against each other in the Mutara Nebula, but Kirk was finally able to disable Khan's hijacked starship and the Enterprise disabled the Reliant, severing the latter ship's port nacelle from its support pylon. Determined to destroy Kirk, a fatally wounded Khan activated the Genesis Device, which would not only destroy the Reliant, but the Enterprise as well when it exploded - which did not have a functional warp drive at the time.

Fortunately, just before the Genesis Device exploded, Spock entered the irradiated control chamber and brought the warp drive back online. The Enterprise was able to warp away as the Genesis Device exploded, taking the Reliant with it. Within a few hours, a new star system had been created, complete with an apparently habitable planet. But in the process, Spock died due to radiation poisoning. (TOS movie, novelization & comic adaptation: Star Trek II: The Wrath of Khan; WizKids module: Attack Wing)

The Last Unicorn RPG module: All Our Yesterdays: The Time Travel Sourcebook gives the date of Enterprise's retirement to training vessel status as 2277.

Final days[]

Shortly after Spock sacrificed himself to save the Enterprise and her crew, the ship returned to spacedock. There Kirk and the rest of the crew learned that the Enterprise was to be decommissioned - the ship had been in service for 40 years by then. Harry Morrow pointed out to Kirk that 20 of those years were manned by the fellow admiral, and his crew.

Dr. McCoy began exhibiting strange behaviors, such as breaking into Spock's quarters and collapsing in Kirk's arms when the Admiral went to confront him. Sarek soon arrived to ask Kirk about Spock's katra, or immortal soul, and it was then the two men learned that Spock had transferred his katra into McCoy.

Enterprise destruction

The destruction of the Enterprise

Starfleet refused to allow Kirk to return to the Genesis Planet to retrieve Spock's body, so Kirk and his senior staff decided to go without Starfleet's approval. Kirk and his staff stole the Enterprise, and left for the Genesis Planet. What they didn't know was that a Klingon Bird-of-Prey commanded by Kruge was waiting for them at the planet. When the Klingons managed to disable the Enterprise, Kirk activated the ship's auto-destruct device, and the ship was destroyed while in orbit of the Genesis Planet in 2285. (TOS movie, novelization & comic adaptation: Star Trek III: The Search for Spock; TNG video game: Echoes from the Past; WizKids module: Attack Wing)

During the final ten seconds of the auto-destruct countdown, the Enterprise reflected on the fact that it had possibly become a sentient being. It regretted that it would not know the future, but it was content to sacrifice itself in battle rather than be decommissioned and disassembled. (TOS - Strange New Worlds IV short story: "Countdown (short story)")

Kirk and his crew were able to commandeer the Klingon ship, and used it to travel to Vulcan, where Spock's body and katra were reunited. (TOS movie, novelization & comic adaptation: The Search for Spock)

So significant were the accomplishments of NCC-1701, that Starfleet re-used this registry (with the addition of a letter suffix) for each of the six subsequent starships (to date) to have been christened Enterprise. (TOS movie, novelization & comic adaptation: The Voyage Home)

Alternate Enterprises[]

Several alternate timeline and illusory versions of the Enterprise have been encountered.

In an alternate timeline created when Yeoman J. Mia Colt was sent forward in time from 2254 to 2293 after her tricorder scans released the tachyon energy contained in an Argollian artifact known as a Keepsake, Pike remained in command of the Enterprise until it was decommissioned, after which it became a popular attraction at the San Francisco Smithsonian Museum of Air, Sea and Space. He was then placed in command of the USS Enterprise-A. (EV comic: "Future Tense")

In a timeline where the Romulan Star Empire had conquered the Federation, the Enterprise was taken by the Romulans as a trophy and impounded in Earth Spacedock. In the 24th century, she was discovered by William Riker's band of rebels who sought to use her to find any remnants of the Federation that might still exist. (TNG comic: "Deviations")

In a timeline where there existed six Guardians of Forever instead of a singular portal, Enterprise crewman Beckwith covertly supplied drugs to his fellows to cope with the stress of the job. When his scheme was found out, he escaped down to Gateway and one of the Guardians' portals. This caused the Enterprise to be overwritten by the SS Condor before Kirk and Spock restored history. (TOS - Harlan Ellison's The City on the Edge of Forever comics: "Issue 2", "Issue 3", "Issue 5")

In a timeline created by Christopher Pike when he avoided his own exposure to delta radiation in 2266, he retained command of the Enterprise during the Battle of Icarus IV. Though reinforced by the USS Farragut, Captain Pike's unwillingness to outright destroy the Template:Chr led to a renewal of the Federation-Romulan war, his actions being seen as a sign of weakness by the Praetor of the Romulan Star Empire. (SNW episode: "A Quality of Mercy")

In a timeline created when Sera destroyed Toronto in 2024 and killed a young Khan Noonien Singh, the United Earth fleet ship Enterprise was commanded by James T. Kirk. (SNW episode: "Tomorrow and Tomorrow and Tomorrow")

The Enterprise's complement also included at least two maintenance vehicles called repair wagons, and a small pod-like vehicle called the capsule which detached from the underside of the saucer section in a similar manner to later captain's yacht designs. (TOS comic: "Life Form Nonexistent")
