USS Galaxy Timeline - From 2100 AD to 2152 AD


Credits: This timeline chronology was originally compiled by James Dixon. Modifications and additions by Liam Collins and Ian Dickson. Movie and episode summaries can be located here. Novel timeline by Geoff Trowbridge can be found here. Some liberties have been taken in aligning dates.

This timeline is used in conjunction with the USS Galaxy Email Fan Fiction Writers RPG as a reference guide. Ever feel like writing, but don't know where to start? we're a small group who love writing with each other to build an environment of our own. Kinda like a combination of Tabletop RPG's and Choose-Your-Own-Adventures. You're welcome to be a part of it. We're always looking for more writers.

2100
- The Synthococcus immunization is developed by John Pearce [Starfleet Medical Reference Manual].
- On Earth, the Centenary Conference looks at what the 22nd century will bring. Authorities trace the evolution of propulsion, communications, and electronics and the development of political and economic alliances. Other speakers look to the future with forecasts ranging from the prophetic to the short-sighted [Spaceflight Chronology, Worlds of the Federation].
- This is the era of the European Hegemony: a loose political alliance on Earth and the beginnings of a world government [TNG: "Up the Long Ladder"].
- Sometime during this century, the Quadros I probe of the Gamma Quadrant will map the ternary Idran system, and run a hydrogen-alpha spectral analysis on this star located some 70,000 light years from Bajor. The wormhole from the Alpha to Gamma Quadrants discovered in the 24th Century opens near the Idran system [DS9: "Emissary Part I and II"].
- Admiral Forrest is born [Conjecture. Assumes Admiral Forrest was 51 in ENT: "Broken Bow"].
- The future Mrs. Rianna Mayweather, Travis' mother, is born in America on Earth [Conjecture. Assumes Rianna is 53 in ENT: "Horizon"].
2101, June
The S.S. "Ark" (UESPA 15) reaches Tau Ceti. Due to damage suffered during an ion storm, planetary surveys conducted show no planets capable of supporting Human life. The entire vessel is disassembled and survival domes are built on a low gravity moon in orbit around the first planet [Starfleet Tactical Database Series II].
2102
- The S.S. "Hokule'a" is launched on a deep space exploration mission to the Ficus sector, a DY-500-C ship commanded by Melinda Snodgrass [TNG: "Up the Long Ladder"].
- The last time Ambassador Suval fired a weapon prior to 2152 [ENT: "Cease Fire"].
2103 COLONIZATION OF MARS
- The colonization of Mars begins [VOY: "The 37's"]. One of Jean-Luc Picard's ancestors is involved in this process [Star Trek VII: "Generations"].
[ENT: "Terra Nova" establishes that Utopia Planitia already exists in 2067 when the Conestoga leaves for Terra Nova. Whether this is a continuity error, depends on the definition of the term "colonization". Maybe the Voyager reference refers to a large-scale terraforming of the planet, with mining and orbital facilities already existing]
- The very first interplanetary colonization missions had been conducted with ships using nuclear reactors, possibly beginning in the 2060's, but this would appear to be a later, more permanent and independent form of settlement at Mars [ENT: "Borderland"].
- Mars is (re?)colonized by Humans from Earth. Most likely this is connected with Mars' independence from the British "Three World Empire" [VOY: "The 37's"].
- The self-aware AIs of Arretius begin to lobby for recognition of their sentience and rights as free-willed creatures. There is surprisingly little opposition to this among the enlightened Arretian population, and so self-aware AIs are given full citizenship, and eleven years later will be given the right to vote in referendum. In recognition of these rights, the machines will exercise their freedom to procreate and create tremendous numbers of new self-aware AIs. However, this will not significantly change the number of machines; most self-aware AIs "exist" within and between the global computer network. However, it will not be long before artificial citizens greatly outnumber the organic Arretians. The organics rarely feel threatened by this, however, for without exception every AI's motivation is the health, safety, and luxury of the living citizenry. Of course, there is wide variation in opinion, both among the machines and among the organics, as to the best expression of this motivation; even very similar AIs have different personalities and therefore different ways of fulfilling their purposes for existence [Starfleet Battles].
- The United Martian Colonies is founded at this time. It is apparently a jurisdiction independent of any Earth government.
- At some point in the process of colonization, the Fundamental Declaration of the Martian Colonies is made, which comes to be known as an historic legal document which set a precedent in interstellar law [TOS: "Court-Martial"].
- The building of the E.C.S. Horizon is completed and the ship is put into service. Travis Mayweather's grandfather is the original captain, and the job eventually passes to his son, and then to Travis' brother. During his time as Captain, Travis' grandfather performed five different jobs on the Horizon at the same time, two of which were on the bridge [50 years before ENT: "Horizon"]
- The engine for the Horizon, a J Class freighter, was designed by Zephrem Cochrane, and the rumor was that Cochrane signed the casing of each warp reactor himself [ENT: "Horizon"].
- Kolos begins serving as an advocate in Klingon court [fifty years before ENT: "Judgment"] In his early years as an advocate, Kolos won some 200 cases, before the warrior class began to take over the justice system.
- Sometime during 2103, a Vulcan science vessel surveys the 7th planet of the Berengeria system and reports encountering winged lizards that could breathe fire. The accuracy of the report is considered questionable [more than 50 years before ENT: "Bound"].
2104
A warp-driven Earth colony ship departs Earth. It will colonize Nova Empyrea in the Campana Sector, a world of controlled genetics [TOS 72: "The Better Man"].
2105
- Eight women are brutally killed in the Mars Colonies by an entity previously known as "Jack the Ripper" and later known as "Redjac" [TOS: "Wolf in the Fold"].
- The "S.S. Lafayette UESPA 02" starliner colonizes New Paris [TOS: "Errand of Mercy"].
- The Viktor Korporation "Yuri Gagarin" DY-732 ship, commanded by Winrich Kolbe, is launched on a colonization mission to the Ficus sector [TNG: "Up the Long Ladder"].
- The Taurean star system is briefly explored and a spaceship is lost near there. Over the next 164 years, a ship will disappear in this region exactly every 27.346 years [TAS: "The Lorelei Signal"].
- At twenty five years of age, the precocious Emory Erickson begins work on what will become the transporter [Speculation, based on ENT: "Daedalus"].
2106
- The Susuru colonize Okeanos (Eris V) not knowing of the Human colony [TOS 66: "From the Depths"].
2108
- UESPA rescue craft arrive in the Tau Ceti system and remove the 418 survivors of the S.S. "Ark" (UESPA 15). The survival domes will remain and in time will be visible to the future Starbase 12 [Starfleet Tactical Database Series II].
- War breaks out between the Susuru and the Human colonists on the water world Okeanos (Eris V) [TOS 66: "From the Depths"].
- A possible date for the death of Mestral, one of the Vulcans who was involved in first contact with the people of Earth in March 1958 [150 years after first contact, ENT: "Carbon Creek"]
2109
A.G. Robinson, future test pilot, is born [Conjecture based on ENT: "First Flight"].
2110
- A United Earth Government is established [TNG: "First Contact"].
- Around this time, Halaylah's artist's colony on Atropos has fallen. The Devil's Heart will remain buried within her tomb until 2368 [TNG Giant Novel 13: "Devil's Heart"].
- By this point, some 60 years after World War Three, war has been almost completely ended on the Earth and disease and crime are much diminished. The Enterprise crew is born into this almost ideal Earth and are raised to believe all things are possible.
- At twenty five years of age, the precocious Emory Erickson begins work on what will become the transporter [Speculation, based on ENT: "Daedalus"] He is a colleague of both Henry Archer and of Zephrem Cochrane [ENT: "Daedalus"].
2110, October 9
- Jonathan Archer is born in San Francisco on Earth. He is born and raised as an explorer. His father is Henry Archer, the famous warp engineer [Conjecture - A birthdate was never formally given, but October 9 is the actor'. One assumes Archer was 41 in ENT: "Broken Bow" and 11 in the flashback sequences].
2111
The process of stamping out the last remnants of war, crime, poverty and hunger on Earth begins [40 years before ENT: "Broken Bow"] By 2150 the task has been largely achieved.
2112
- The service life of "Assist" class space towers comes to an end [Spaceflight Chronology].
- The Andorians make an incursion into Vulcan space, an event which is somehow connected to the status of Raytan [ENT: "Cease Fire"].
- At the age of twenty, Dr. Phlox serves as a medic with the Denoblian infantry [Conjecture - Phlox's service with the infantry is not given a specific date - ENT: "Cease Fire"].
2112, May
- After 40 days alone in space aboard the "Bonaventure II," Cochrane encounters the Companion, an intelligent entity composed of ionized gas. The Companion rejuventates 87 year old Cochrane and terraforms Gamma Canaris N (Planetoid 527) to suit him [TOS Giant Novel 18: "Federation"].
- Zefram Cochrane is reported missing [TOS: "Metamorphosis", Star Trek Maps].
- Following the disappearance of Zefram Cochrane, the planet Cochrane I (Zeta Riguli VII) is settled by Humans and Alpha Centaurians. Rich in dilithium and radioactives, Cochrane I will quickly become a thriving industrial planet, hosting the central administrative center for the U.F.P.'s Department of Colonization and numerous subsidiary agencies and organizations [FASA Roleplaying Guide, Second Edition].
2113
- The Cicada star system (sector 4423) is briefly explored. Over the next 150 years, a ship will disappear in this region exactly every 27.346 years [Star Trek Log 2]
- Having learned the lessons of the last World War, the first united Earth government is established. Australia is the only nation that declines membership [Spaceflight Chronology, TNG: "First Contact", Enterprise Exploration Timeline, Star Trek Star Charts. 50 years after Cochrane's first flight].
- Also around this time, the Klingon justice system begins to change as the warrior class comes to have greater influence over all aspects of Klingon life. Soon, the Klingon Empire begins to develop a much more aggressive stance and works to expand its boundaries [Conjecture based on ENT: "Judgment"].
2113, Early April
At least three probes are launched from the Dokaalan system pleading for help when their world begins to descend into catastrophic disaster after seismic activity begins to break their world apart [Conjecture - TNG: "A Time to Sow"].
2114
- A cure is found for hyperthyroidism [TOS 56: "Legacy"].
- Dr. Phlox begins working as a medical physician [40 years prior to ENT: "Damage"].
2114, April
Dokaa is destroyed by intense and cataclysmic seismic activity. Only those who worked on the asteroid belt within the system survive [Conjecture - TNG: "A Time to Sow"].
2115
- Under UESPA contract, the "Orlando" class transport is produced. Based upon the "Monticello" class cargo carrier, these in-system transports are propelled by General Space Corp. fusion thrusters [Starfleet Tactical Database Series II].
- The "UESPS Marco Polo" encounters the Galactic Maelstrom, henceforth known as 'Polo's Bolos': twin black holes in motion [TOS Original Novel 15: "Galactic Whirlpool"].
2116
The U.N.S.S. "Magellan" is decommissioned and converted to a hospital ship which will serve an even longer life in the Sol system [Starfleet Tactical Database Series II].
2117
- The Warp 5 Complex is established to create technology that will allow humans to safely explore deep space. Zefram Cochrane is present during the groundbreaking ceremony [ENT: "Broken Bow"]. Henry Archer, Jonathan Archer's father, is second only to Cochrane in his importance to this program [ENT: "Singularity"]. The Warp Five program would eventually come under the jurisdiction of the new entity, Starfleet, working in conjunction with the Vulcan Advisory Council [ENT: "First Flight"].
- Zephrem Cochrane, now 87 years of age and a resident of the Alpha Centauri system, soon takes off for "parts unknown." He takes a one man vessel on a trip, and is never seen from again. Rumors surround his depature, and some believe he was setting out to test a new warp capable vehicle [ENT: "Future Tense"]. Cochrane's disappearance became the most famous missing persons case in history [ENT: "Future Tense", Cochrane disappeared approximately 150 years prior to TOS: "Metamorphosis" (2267), specific date from Star Trek.com character bio - Again, the TOS writers set the date and the TNG/FASA writers moved it a few years earlier. we see from this timeline Cochrane leaving AC in 2112 and encountering the Companion, and meeting Kirk later on is this timeline. So why did they advance it a few years? Who knows?].
2118, October 9
Jonathan Archer's eighth birthday. He receives as a gift his first astronomy book, which has a picture of the Arachnid Nebula on its cover. He would get to explore this nebula in November 2151 [ENT: "Fusion", birthday taken from birthdate of Scott Bakula].
2119
- Peter Lauritson commands the S.S. "Tomobiki" RT-2203 vessel on a deep space exploration mission of the Ficus sector [TNG: "Up the Long Ladder"].
- Charlie 'Trip' Tucker III is born in Florida in the United States on Earth (Speculation. Assumes Trip was 32 at the time of ENT: "Broken Bow")
- Zefram Cochrane speaks at the groundbreaking ceremony for the Warp 5 Complex [ENT: "Broken Bow"- Note: This is in direct conflict with his leaving Earth in 2117, so take it as you will. Either flip this date to 2117, or bring his leaving to 2119. I myself would choose the latter - too much confusion] Henry Archer, Jonathan Archer's father, is second only to Cochrane in his importance to this program [ENT: "Singularity"]. The Warp Five program would eventually come under the jurisdiction of the new entity, Starfleet, working in conjunction with the Vulcan Advisory Council [ENT: "First Flight"].
- Zephrem Cochrane, now 87 years of age and a resident of the Alpha Centauri system, soon takes off for "parts unknown." He takes a one man vessel on a trip, and is never seen from again. Rumors surround his departure, and some believe he was setting out to test a new warp capable vehicle [ENT: "Future Tense"]. Cochrane's disappearance became the most famous missing persons case in history [ENT: "Future Tense", Cochrane disappeared approximately 150 years prior to TOS: "Metamorphosis" (2267), specific date from Enterprise exploration timeline].
- The future Major Hayes is born in the United States on Earth (ENT).
2120
- The H.M.S. "Lord Nelson," DY-500-B ship, commanded by Young Jae Kim an d owned by Lloyds of London is launched on a deep space exploration mission to the Ficus sector [TNG: "Up the Long Ladder"].
- Vulcan Ambassador Sorval is first stationed on Earth [Speculation from ENT: "Broken Bow"].
- The S.S. Enterprise, a warp 3.2 capable passenger liner of the Declaration Class sets out on its maiden voyage [Date speculation. A picture of the S.S. Enterprise appears in the Rec Deck of the USS Enterprise in Star Trek I: "The Motion Picture". Other references: "Star Trek Maps", Spaceflight Chronology, Star Trek Communicator magazine].
2121
- As a boy, Jonathan Archer takes a deep interest in space travel. He makes a working model of a Starfleet ship with his father during this year, and successfully learns to fly it. The construction of his father's Warp 5 ship has not yet begun at this time [ENT: "Broken Bow"].
- 11 year-old Jonathan Archer visits the Sol Museum of Aeronautical Science, and spends time with T'Rama, eventual mother to Sarek [Strange New Worlds V - "A Girl for Every Star"].
- Travis Mayweather's father takes command of the E.C.S. Horizon at the age of 23. His wife Rianna, who comes to be both the ship's medic and Chief Engineer, supports him through this difficult time. It is unclear why he was thrust into command at such a young age - but it may have been because Travis' grandfather had passed away after captaining the ship for some 18 years. [Speculation based on ENT: "Horizon" - Travis' father was one year younger than Paul Mayweather was when he took command in 2152].
2122
- Malcolm Reed is born in the United Kingdom on Earth [Speculation. Assumes Reed is 29 in ENT: "Broken Bow"].
- T'Pau is born on Vulcan [32 years prior to ENT: "The Forge"].
- As part of the process of working together with the planet Agoran, the Ministry of Security on Vulcan begins dispatching agents to infiltrate the criminal elements of Agoran, and in so doing put an end to corruption. In all, 109 agents would be dispatched. Ultimately, seven of these agents would become beguiled by the corruption on Agoran and refuse to return to Vulcan when the mission was over, instead opting for a life of crime as smugglers [30 years before ENT: "The Seventh" - Note: T'Pol indicates she was too young to be given this assignment at the time ("I'm not that old Captain"), which would tend to mitigate against the earlier assumption of this timeline that she was born in 2086, which would make her 36 at this time].
2123
- Hoshio Sato is born in Japan on Earth [Speculation. Assumes Sato is 28 in ENT: "Broken Bow"].
- Trip Tucker's baby sister Elizabeth is born in Florida. She would be killed in the Xindi attack of April 2153 [Speculation from ENT: "The Expanse"].
- Trip is four years of age, which is the age that Sim, the clone of Tucker, was when he was being read to [ENT: "Similitude"].
- Amanda Cole is born in Florida on Earth [Speculation - Amanda is roughly the same age as Trip, but it is suggested she is slightly younger than him].
2123, November 27
- A privately-funded ship, the Mariposa, departs Earth carrying two groups of colonists bound for the Ficus sector and the two planets selected as their new homelands. From the information on the view screen in [TNG: "Up the Long Ladder"], it is clear that the vessel is a DY-500 class vessel, similar in appearance to the DY-100 class [TOS: "Space Seed"]. The craft settles colonists on Bringloid V. It later crashes on the planet Mariposa while attempting to settle a second group of colonists. There are only five survivors of the crash, who attempt to keep their colony viable using cloning technology [TNG: "Up the Long Ladder"].
- From the listing that Data peruses of ships that left Earth around this time, it is clear that space travel has become a regular occurrence[TNG: "Up the Long Ladder"].
2124
- The first Interplanetary Federation congress meets. The Vulcan delegation introduces a referendum on Federation-wide Warrantorship [TOS 25: "Dwellers in the Crucible"].
- The meeting of the First Federation Congress. Presumably, early drafts of the Articles of Federation would have begun at this time [TOS 25: "Dwellers in the Crucible"]
2125
- The Proto-Federation Era begins. Over a hundred people, accompanied by staffs totaling more than a thousand assistants, begin to draft the Articles of Federation of the U.F.P. on Babel (Wolf 424). [Starfleet Medical Reference Manual, TOS 6: "The Abode of Life"]
- Vulcan Fleet Commander Savaj, commanding the "V'Kreeth," opens up a whole quadrant of space and single-handedly attempts to keep Vulcan from joining in forming the United Federation of Planets [TOS 5: "The Prometheus Design"].
- Y-500 Class vessels (presumably inclusive of the DY-500) are decommissioned and are no longer in service [Date is speculation. Y-500 vessels are revealed to have been out of service "for decades" in ENT: "Strange New World"].
2126
- Travis Mayweather is born halfway between Dralax and Vega Colony. His childhood is spent in space, and he is raised on a series of cargo ships. Travis grew up on the J-Class Freighter E.C.S. Horizon, which he described in ENT: "Fortunate Son" as a little smaller than a Y-Class, but with the same basic design. He commented that at Warp 1.8 there's "a lot of time between ports" and it was during such a time that he was conceive [Travis is noted as being 26 in ENT: "Dead Stop". Events taken from character back story, ENT: "Fortunate Son" and ENT: "Horizon". In the original backstory, it indicated Travis was born "during a two year run somewhere between Alpha Centauri and Arcturis Prime"].
- Liana is born on the Katare home world [Trip speculates Liana may have been 4 years old when her ship crashed ENT: "Oasis"].
2127
- At age eight or nine, Trip spends some time picking up leaves with his Dad [ENT: "The Crossing"].
- Age eight was also the age that Sim, the clone of Tucker, was when he was playing with the remote control shuttle [ENT: "Similitude"].
2127, May 8
The Articles of Federation are first considered on Babel, during the usual Diplomatic Summit of Spacefaring Races.
2127, June 6

- Milton Kornheiser starts designing interstellar spacecraft [Spaceflight Chronology].
2128
- At age 42, T'Pol undergoes a dental procedure [23 years before ENT: "Dear Doctor"]
- Travis' younger brother Paul Mayweather is born aboard the J Class freighter Horizon [Speculation based on ENT: "Horizon"].
2129 INVENTION OF THE TRANSPORTER
- Alpha (Procyon A) III (Terra 4) becomes the 6th Non-terran U.E.N. member--the first colony to be launched after the advent of warp drive, a pacifist culture settled by Buddist Chinese [Star Trek Maps, Starfleet Dynamics]
- At around age 10, Trip Tucker is enamored by tales of the invention of the transporter.His admiration of Emory Erickson and his work is one of the key reasons that Trip ends up becoming an engineer [Dates are speculation based on ENT: "Daedalus" - Emory Erickson would have been about 44 years old at this point]
2129, July 9
- Hoshi Sato is born in Kyoto, Japan, the second child of three [ENT: 'In a Mirror, Darkly II"].
2130 Traité d'Unification is signed
- Human and Alpha Centaurian colonists co-settle the planet Hellios (Sigma Wyrenex VI) [FASA Roleplaying Guide, Second Edition]
- A Kantare ship, commanded by Captain Kulann, encounters a severe ion storm. Damage done during the storm results in a plasma leak, explosive decompression, and the ship ultimately crashes on a remote planet. Only the ship's Chief Engineer, Ezral, and his daughter, Liana survive the crash [22 years before ENT: "Oasis"].
- Signing of the Traité d'Unification by all governments on Earth unifying all into a global community [Star Trek: "Articles of the Federation"].
- Baleeza Gral, the Trill Seeker's seniormost reporter by 2380, begins his journalistic career. He reported with two other hosts - Renna Gral and Tristor Gral. Renna was the first host here [Star Trek: "Articles of the Federation"].
2130 - 2132 Circa
Babu, Nyota Uhura's grandfather, is born [Conjecture - Star Trek Lost Era 6: "Catalyst of Sorrows"].
2131
- During this era, the three Gorn home worlds (of the Tau Lacertae IX star system?) first come into contact with each other, through the Ghdar race of explorers. Each are at a different stage of development: Ghdar I (Ghdar) a space age society, Ghdar II (Geydar) an industrial age society, and Ghdar III (Gihdahr) an iron age society. Contact is achieved within a few months of each other, first with the Geydar and then with the Gihdahr. Within a few decades the Gorns will be unified into a single, though stratified, society. The Ghdar are known as the Gray Scales will be the noblemen of the first century after unification (AU), the Geydar are known as the Brown Stripes will be the middle class workers, and the Gihdahr as the Green Scales are offered the lowest jobs. The Green Scales will fight in the front line (generally under Brown Stripe officers) when the Gorn Hegemony fights its first interstellar wars in the years to come. By the late 23rd Century, Gorn society will become essentially casteless though the Green Scales will remain dominant in the military. [Starfleet Medical Reference Manual, Starfleet Battles, TOS: "Arena"]
- At age 12, Trip Tucker goes to his first dance at Bayshore Elementary in Panama City, Florida. Ever after, he regrets not asking a certain girl to dance ["more than 20 years" before ENT: "Fusion"].
- T'Pol enters her training program with the Ministry of Security on Vulcan [Speculation. Assumes a four year program, similar to a degree in Criminology].
- The tenth and last Space Ark, Terra 10, is launched complete with early transporter technology. Of all ten generation ships, only the passengers of this last ship will survive. Shortly after this, the Interstat code that they made use of becomes outdated [TAS: "The Terratin Incident" establishes that this mission happened around 2069, approximately 200 years before the episode took place. I have moved this event to c. 2131 to be consistent with later information from ENT: "Daedalus", concerning the invention of the transporter, as well as to be consistent with the established date of the Conestoga's voyage as the first colony ship. The previous 9 Terra ships would perhaps have been launched within the previous decade or so].
2132
- Buck Bokai dies [DS9: "If Wishes were Horses"].
- Vega IX becomes the 7th extraterrstial U.E.N. colony-member [Star Trek Maps, Starfleet Dynamics].
- Archer takes a trip to East Africa, and at one point observes the birth of a baby gazelle [Age 22 - Archer said he was in his early twenties - ENT: "Shockwave - Part II"]
- Archer considers joining the merchant fleet and signing aboard a freighter, in a series of events that constitute what Archer calls a "long story" [Prior to Starfleet's formation - ENT: "Horizon"].
- The Paraagan mining colony is established [20 years prior to ENT: "Shockwave"].
- A second spaceship disappears in the Taurean region of space, never to be heard from again [TAS: "The Lorelei Signal"].
- About this time, Trip Tucker begins attending High School in Florida. His high school is a rival with the high school that Amanda Cole is attending at about the same time, and the two visit the same movie theater during this time in their lives, unaware of the other [ENT: "Harbinger"].
2133
- Bajoran religious leader Kai Taluno, while traveling in the Denorios Belt, experiences a serious malfunction of his spacecraft and is stranded for several days. Taluno reports having experienced a vision in which "the heavens opened up," nearly swallowing his ship. The Denorios Belt, located in the Bajor system, is the location where at least five of the Bajorans' Tears of the Prophets were found [DS9: "The Emissary"]. Dax said Taluno's vision was sometime during the 22nd century, and this date is purely conjectural.
- A Klingon ship emerges from the Delphic Expanse. The crew had been anatomically inverted and was still alive. Memory of this event prevents Klingons from daring to enter this region of space [20 years before ENT: "The Expanse"].
2134 STARFLEET IS FORMED
- It's charter, to "boldly go where no man has gone before." (sources: conjecture, based on date that Jonathan Archer joined Starfleet. Also, in some promotional material, it was noted that Starfleet is less than 20 years old at the start of Enterprise. Charter phrasing from [Star Trek Encyclopedia - p.690] Part of Starfleet's original charter was the little known Section 31, which allowed for extraordinary measures in the event of a threat on Earth [ENT: "Divergence"]. The inclusion of this authority soon results in the creation of a secretive, black ops division of Starfleet that eventually comes to be known simply as "Section 31." Section 31 emerges as an autonomous group concerned with searching out, identifying, and quietly dealing with potential dangers to the Earth. Members of this organization defy the principles of the Earth (and later the Federation) in order to protect them, which is one of the reasons why Section 31 is not officially sanctioned by Starfleet and its very existence is not acknowledged openly [DS9: "Inquisition", DS9: "Inter Arma Enim Silent Leges"].
- The S.S. Bonaventure, galactic survey cruiser is launched. The Bonaventure will mysteriously disappear on her third voyage, and her hulk will be found in 2269 in the alternate universe of Elysia [TAS: "The Time Trap", date is conjecture. In the episode Scotty said "Captain, there's the old Bonaventure. She was the first ship to have warp drive installed." However, given the ship's markings, I prefer to think Scotty was referring to the first Starfleet ship to have warp drive installed].
- Vulcan finally forms an alliance with the planet Agoran. The agents assigned to infiltrate the corrupt elements of Agoran society are recalled. All but seven return [Speculation of date, based on ENT: "The Seventh"].
- As part of Starfleet's operations, orbital platforms such as Yosemite are built [ENT: "Zero Hour"].
- Arik Soong takes a series of genetically engineered embryos from Cold Station 12. He takes the embryos to a planet into the Trialis system to raise them. This planet is located between the Orion Syndicate and the Klingon Empire [20 years before ENT: "Borderland"].
2135
- At the Roykirk Summer School on Earth, fifteen year-old Charles Tucker develops a proposal for a phase conduit cooling system [Strange New Worlds VI - "Preconceptions"].
- After graduating from her training with the Ministry of Security on Vulcan, T'Pol is given an assignment to track down and apprehend seven former Vulcan agents who have become corrupted during their assignment on Agoran. T'Pol is extremely successful, and apprehends five of the agents, returning them to Vulcan for rehabilitation. However, T'Pol suffers a severe setback while in the tropics of Risa pursuing the last two suspects, Josin and Menos, on foot. During the pursuit, Josin falls, and T'Pol sees Josin reach for what she believes is a weapon. She shoots and kills Josin with an energy weapon, and is immediately overcome by great anguish. Menos escapes. The guilt of killing Josin would force to T'Pol to leave the Ministry of Security and seek guidance at the monastery on P'Jem [17 years prior to ENT: "The Seventh"].
- In grade 10, Charlie "Trip" Tucker encounters his first Vulcan - Mr. Velik. Velik was sent to Earth as part of a cultural exchange, and serves as a teacher in Trip's Florida high school. One notable quote that Trip remembers from Mr. Velik is "challenge your preconceptions, or they will challenge you" ["Strange New World" - date is speculation based on Trip's approximate age].
- At the age of 16, Trip gets his driver's license, and not soon after gets his first car. One of his favorite pastimes is to take his car and drive to Chatkin Point at night with his girlfriend, where they would watch the moon [ENT: "Precious Cargo"] Note, Trip's car is probably a hover car, and not an automobile.
2136
- T'Pol continues her work with a Vulcan elder on P'Jem, trying to work through the tremendous guilt she had after killing Josin. After three months of guidance, the elder decides the only way to resolve the problem is to use an ancient Vulcan technique, the valara, to strip T'Pol of not only her emotions concerning the event, but also her memories as well. The ritual complete, T'Pol leaves the monastery, with no memories of the seventh suspect she was pursuing. She would remain oblivious to this chapter in her personal history until an assignment was given her to capture Menos, Josin's partner, while she was serving on the Enterprise in June 2152 [A few months after the conclusion of her mission in 2135, ENT: "The Seventh"].
- Captain Vannick begins serving in the Vulcan Space Fleet aboard the Ti'Mur [15 years before ENT: "Breaking the Ice", TNG: "A Time to Sow"].

- The U.E.N.S.S. "Balboa" enters a Romulan claimed system on a peace-exploration mission. A squadron of fifty Rihannsu ships destroy the "Balboa" with massed particle beams. The Romulans then use high-powered lasers to decompress the crew compartments of the U.E.S.P.A.S.S."Stone Mountain," and after studying the ship, gain warp drive technology. No trace or record of the fate of either ship is ever found until the 24th century, when Rihnassu archives are examined by Starfleet historians [TOS 35: "The Romulan Way" - Rihannsu #2, Starfleet Battles].
- T'Pol begins her work with the Vulcan Science Directorate [Speculation based upon ENT: "The Seventh"].
2138

- During a experiment involving a new technology, the quantum transporter, Emory Erickson's son Quinn volunteers to test the device. Emory had invented the transporter some years earlier, and while still at a relatively young age (possibly 54) wanted to top his earlier achievement. This zeal prevented him from considering the risks properly, and Quinn's signal was lost. Quinn would continue in this non-existence, and Emory would work to try and save Quinn until the events of ENT: "Daedalus" fifteen years later.
- One of the probes launched by the Dokaalan pleading for help encounters an ion storm [TNG: "A Time to Sow"].

A misunderstanding of navigational instructions is compounded by a weapon fire-control systems failure when the U.E.N.S.S. "Scythe," a "Verne" class ship commanded by Captain Henri Fourrier, is accidentally blind-sided. Two Terran destroyers, the UE.S.P.A..S.S. "Hammer" and U.E.N.S.S. "Enmity" are annihilated, killing 232 crewmen. This accident vividly points out the need for a single command structure and a central training facility for starship crews of all Earth members: a Star Fleet Academy.
- All Earth ships officially switch to USS desigantion, under United Earth Space Probe Agency and United Earth Nations Spacefleet combined Operations Agreement.
- At age 18, Hoshi Sato joins Starfleet and begins training - which involves extensive linguistic studies [Speculation based on her age].

2142, June
Continued advances are made in communications theory and technology. Research leads to a level of near-perfect efficiency. From this point on, messages sent via warp radio travel at the unbelievable speed of Warp 15, or 3375 times the speed of light. Over the next two years, all starships have their communications equipment modified accordingly [FASA Roleplaying Guide, Second Edition].
2142, October [reference stardate 1/0910]
By this time, the Klingons have begun to perfect shipboard disruptor technology, which they are deploying throughout their fleet. With their Romulan War now over, the Orions now realize that the U.E.N. and the Klingon Empire must eventually encounter one another. At this moment, however, the Klingon military is occupied with raids against the weakened Romulan border. The Orions nevertheless fear that the Klingons will soon turn their attention again in the direction of Rigel and her interstellar holdings. Realizing that any contact between the U.E.N. and the Klingon Empire must inevitably lead to armed conflict, the Orions hastily negotiate several non-aggression and trade treaties with the U.E.N. [FASA Roleplaying Guide, Second Edition].
2143

2143, August
- The NX program, which has worked to design and test a vessel capable of breaking the Warp 2 barrier, is reaching its climax as the test pilot for the first flight is chosen.
- Jonathan Archer, one of four commanders in the program who hopes to pilot the craft is disappointed when he is passed over for the job which instead goes to A.G. Robinson.
- In the test, Robinson successfully breaks the Warp 2 barrier, but the craft is lost, and Robinson barely manages to eject in time to save his life.
- The Vulcan Advisory Council is not impressed, and they demand that the program be stopped for the time being. They also call into question the engine design, an engine design dear to Commander Archer, as it is the one that his father had engineered prior to his death.
- Determined to prove the Vulcans and Starfleet wrong, Archer and Robinson team up and steal the NX-Beta test ship to try and again break the Warp 2 barrier. They succeed in their attempt, and manage to maintain a steady velocity of Warp 2.5.
- Returning to San Francisco to face punishment for stealing the second ship, Archer and Robinson manage to convince Commodore Forrest of the merits of their test, and the two are able to escape court martial and are instead grounded for three months.
- The Vulcan Advisory Council has the NX program begin a series of simulations and tests.
- It was during this time that Charlie Tucker and Jonathan Archer first met [All events taken from ENT: "First Flight"].
2143, September
About now in his time at Starfleet, "Trip" Tucker travels to Alice Springs in Australia to do survival training. Jonathan Archer also participates [Date is speculation, based to a certain extent on ENT: "First Flight". Trip talks about this event in "Vanishing Point," in a sequence that is part of Hoshi's transporter delusion - I am assuming that she imagined Trip repeating a story he had earlier related].
2143, October
While on Titan as part of the Omega Training Mission with Captain Archer, Charlie "Trip" Tucker encounters problems while on an extra vehicular (EV) exercise. His EV pack freezes up and he experiences nitrogen narcosis. Archer convinces Trip not to remove his helmet while in the vacuum [Speculation of date - assumption made that this happened before Trip was assigned to Utopia Planetia, and after he met Archer].
2143, November
Robinson and Archer are permitted to fly again, after three months of being grounded.
2144

- Most Orion trade families close their operations with the U.E.N. in the face of Klingon trade vessels returning to the Rigel colonies. Through masterful timing of ship arrivals, the Orions keep the Klingons and U.E.N.. unaware of each other's presence in the OUTLANDS for many years, despite U.E.N. displeasure at the closing of many Orion ports [FASA Roleplaying Guide, Second Edition].
- The U.S.S. "Atlas", a Federation cargo ship operating near the frontier of Federation space, is attacked and destroyed, though this is not known until the recovery of its marker/recorder buoy containing a complete transcript of the events preceding the "Atlas'" destruction. The "Atlas" was destroyed by a Romulan patrol craft for wandering into Romulan territory. At first the Romulans suspect that U.E.P. incursions into their space may be a Klingon deception. Later, the Imperial Council, remembering the 'Klingon lesson', decides not to risk negotiation with the U.E.P., in the hope that destruction of all intruders will keep the U.E.P from expanding into Romulan Space. [FASA Roleplaying Guide, Second Edition, Spaceflight Chronology].

2145, March
Commander Duvall is selected to fly the NX-Delta in the next test flight.
2145, April
- Duvall, a close friend of Archer's, breaks the Warp 2 barrier in the test ship NX-Delta. He reaches a speed of Warp 3, and goes down in history, setting the groundwork for Starfleet's next big project: the Warp 5 starship [date is speculation from ENT: "First Flight" - 8 months after the testing regime completed, and 5 years before the keel was laid for the Enterprise].
- Where it took the Vulcans 100 years to break the Warp 2 barrier, the people of Earth completed the task in 82 years [ENT: "First Flight", TNG: "First Contact"]
2145, October 18
The U.S.S. "Amaretto", operating within Earth-patrolled territory, is attacked by two starships of unknown configuration. The vessels are similar to those described by the commander of the U.S.S. "Atlas". The freighter is severely damaged, but the attackers break off when a Terran four-ship destroyer squadron appears. The Star Fleet Command flagship attempts to establish communications for purposes of identification and explanation. The alien vessel fails to understand or ignores all efforts to communicate, and successfully evades pursuit [FASA Roleplaying Guide, Second Edition].
2146
- The Delta VII outpost is destroyed by 'space pirates.' Years later, it is discovered this was another Romulan criminal act. [Spaceflight Chronology, [FASA Roleplaying Guide, Second Edition].

2146, November
- A total of 32 unarmed warp-driven message probes are launched toward areas of uncharted space from starships and planets near Delta VII. Each probe contains complete symbolic instructions and messages in every known language. The messages request the establishment of diplomatic relations and the resolution of any existing dispute via peaceful means. No probe is ever regained, and all are assumed to be lost or destroyed by the 'pirates.' In reality, Orion Trading Cartels recover three of he probes, and the idea of 'Letters of Marque and Repraisal' first emerge from eh Orion Halls of Trade [FASA Roleplaying Guide, Second Edition].

2147, November 30
The United Earth Planets Council passes a special directive to Star Fleet Command. In addition to new, massive appropriations for fleet construction, the directive orders several cruiser formations redeployed to strengthen defenses in the area where the U.S.S. "Atlas" was lost. A special scout squadron under the jurisdiction of Star Fleet Intelligence Command is dispatched to obtain any possible information on the pirates, and, if possible, to make diplomatic contact. The squadron consists of twelve warp-driven patrol craft, each manned by a crew of 15 volunteers. None of the craft are ever seen or heard from again [FASA Roleplaying Guide, Second Edition].
2147, December
Faced with threats that the U.E.N.. will revoke its non-aggression agreements because of the closure of Orion ports to even emergency traffic, the Orions reopen their ports to U.E.N.. shipping on a limited basis. They also sign new treaties with the UE.N. These agreements provide the Orion worlds with a promise of protection from outside aggression, but bind the Orions only to not directly attacking the U.E.N,. This opens the door for the Orions to trade with both sides if and when the Klingon Empire and U.E.N. meet in conflict. They continue to try and keep both sides ignorant of the other's existance [FASA Roleplaying Guide, Second Edition].
2148
- The Earth merchant captain E. A. Jacoby and his crew encounter some Klingon traders led by retired Naval Officer Kassam on an Orion colony planet. The traders are aware that they have made contact with a previously unknown species, but the Klingons hide the true importance of the incident, all the while pumping the traders for information on the U.E.N.. As an experienced trader, Captain Jacoby has encountered a number of new races (all customers of the Orions) in past visits to Orion ports, and so he simply passes along the routine U.E.N.. contact material. Though Jacoby claims to have filed the proper reports to the U.E.N.. Contacts Bureau, those records are never found. Meanwhile, the Klingons begin a crash program to learn all they can about this potential rival that they call the "Human Empire". They capture a number of Terran ships and interrogate the crews using their new 'Mind Probe' technology. [FASA Roleplaying Guide, Second Edition]

Paul, Travis' younger brother feels somewhat abandoned, while Rianna, Travis' mother is very supportive [ENT: "Horizon"].
2149, August

- Starbase 3 is completed and assumes operational status. This base is used as the primary command headquarters for Star Fleet Operations during the Romulan War. Its great distance from the front makes command, control, and communications protocols difficult to execute efficiently. For this reason many Star Fleet squadron and group commanders are able to exert enormous personal authority, responsibility, and initiative while fighting this war [FASA Roleplaying Guide, Second Edition].

2149, November

- Captain Archer is having difficulty selecting a helmsmen for the Enterprise. To help him decide, he contacts each of the previous commanding officers of each of the candidates he is considering. One candidate is Travis Mayweather, so he contacts Travis' father aboard the E.C.S. Horizon. The response is a one sentence evaluation "I've never met a more natural stick and rudder man and you'd be a fool if you don't choose him" [2 and a half years before ENT: "Horizon"].
2150, August
Dr. Phlox, a Denobulan, comes to Earth as part of a the Interplanetary Medical Exchange program, sponsored by the Vulcans. While on Earth for the next nine months, he makes it a point to study a number of Earth religions. He studies Hinduism, spends two weeks at a Tibetan monastery, attends Mass at Saint Peter's Square and is allowed to attend the Tal-Shanar at the Vulcan consulate. [ENT: "Cold Front", ENT: "A Night in Sickbay" 9 months on Earth is mentioned in ENT: "Vanishing Point" in Hoshi's transporter delusion].

ENT Episode "Broken Bow"
- In the nine decades following Zefram Cochrane's visionary warp flight in space and the First Contact that followed, the human race has been slowly guided by the Vulcans toward developing the Warp Five engine. Mankind is at last able to explore the virgin depths of space with a revolutionary new starship, the Enterprise NX-01, under the command of Captain Jonathan Archer. Plans to launch Enterprise are moved up when a Klingon courier, Klaang, is shot down by unknown assailants and crash-lands in Broken Bow, Oklahoma. Feeling that the Vulcans have been condescending toward mankind for years, Archer insists it's the humans' responsibility to return the injured Klingon to his homeworld alive.
- The Enterprise speeds along her way, but suddenly the ship experiences a power failure and unknown chameleon-like aliens invade and kidnap Klaang from Sickbay. Dr. Phlox examines a captured alien and discovers he's a Suliban who has been genetically altered. Archer orders Mayweather to set a course for the Rigel system, Klaang's last stop before crashing on Earth. At Rigel X, the Enterprise away team discovers an amazing multitude of alien life at a trading complex there. Archer eventually meets Sarin, who tells him of a Temporal Cold War in which the Suliban are being used to incite internal strife within the Klingon Empire. Klaang was bringing proof of this back to his High Council in order to avoid the Empire being thrown into chaos. Hidden Suliban soldiers suddenly attack, forcing Archer, Sarin and the rest of the away team to fight their way back to Enterprise. During the extremely intense firefight Sarin is killed.
- The crew track the Suliban vessel to a gas giant planet, and discover a huge Suliban mothership, or "Helix," with 3000 lifesigns on board. They are attacked by several individual Suliban cell ships, but manage to capture one with the ship's grappler. Archer and Tucker learn to fly the stolen craft and use it to infiltrate the Helix while Enterprise hides in a dense upper layer of the atmosphere. Archer and Tucker find Klaang and release him while fending off the Suliban with their new phase-pistols. While Tucker takes the Klingon back to Enterprise, Archer stays behind to set off a magnetic disruptor that dismantles the Helix. Trying to stay alive while waiting for pick-up, Archer discovers a Temporal Chamber used by the Suliban to obtain their orders from a mysterious shrouded figure from the future. Archer is found by the Suliban leader, Silik, and the two struggle against each other in a time-shifted environment. Realizing he's no match for the genetically mutated Suliban, Archer tries to gain some distance by exiting the chamber, where time returns to normal. As Archer runs, Silik fires his weapon dead center into Archer, but at that moment the captain dematerializes, being unwittingly beamed back to Enterprise by a nervous Tucker using the relatively untried bio-transporter.
- Leaving the Suliban behind, Enterprise warps away and successfully delivers Klaang to his homeworld. The Klingon Chancellor draws blood from Klaang, and his scientists find hidden within his DNA Suliban data proving their conspiracy to undermine the Empire.
- Archer receives orders from Starfleet that henceforth, he and his crew are to officially begin their mission of exploration.
