Construction begins late in 2054 and proceeds rapidly due to advances in construction technology.[Non-game 17]
- West Tek Research Facility is established to continue work on a cure for the New Plague. Their viral research and close ties to the Federal government eventually lead to them being chosen for the Pan-Immunity Virion Project 20 years later as well as power infantry armor and laser research.[Non-game 18]
- ZAX 1.2 is brought in to regulate conditions in West Tek. It is not part of the Vault-Tec preservation software, so it does not have any orders to protect humanity after the bombs fall. In the meantime, it calmly calculates data and plays chess with the scientists. Many scientists claim that ZAX is a "big ol' cheater" and draws the game out too much for a computer of his considerable abilities.[Non-game 19]
- HalluciGen, Incorporated introduce their crowd control gas.
- The Anchorage Front Line is established, as the United States increases its military presence in Alaska to protect its oil interests. The Anchorage Front Line causes tensions in the United States and Canada, as the United States attempts to pressure Canada into allowing American military units to guard the Alaskan pipeline.[Non-game 20]
- The first artificial intelligence is born. Limited by memory constraints, its expansion is rapidly halted. The discovery paves the way for future A.I. research in laboratories throughout the United States.[Non-game 21]

- December: As a sign of increasing tension between the two countries, Canada proves reluctant to allow American troops on Canadian soil or allow American planes to fly over Canadian airspace. American and Canadian tensions rise, but Canada eventually backs down, and U.S. troops pass through Canada. This sets the stage for the Canadian annexation in 2076.[Non-game 37]
- The first suit of T-45 power armor is deployed in Alaska. While lacking the full mobility of future versions, this power armor is incredibly effective against Chinese tanks and infantry.

- Vault 79 is completed and all U.S. gold reserves are moved to it in secret from Fort Knox.
- September 15: As China becomes increasingly aggressive with their use of biological weapons, the United States government felt that a countermeasure was needed. The Pan-Immunity Virion Project is officially formed and plans are made to begin experiments at the West Tek Research Facility in Southern California.[Non-game 45]
- Despite claiming that it fights a purely defensive war, United States units are deployed to China. Long supply lines and difficult conditions on the mainland lead to the units becoming bogged down in the fighting. American infantry, mechanized divisions, and power armor units suffer from strained resource and supply lines.[Non-game 46]

- November 9: FEV experimentation (batch 10-011) on rabbits is concluded. Increased size, intelligence, and (this time) aggressiveness is noted. Apparently, it was hard to determine whether the flatworms in the previous experiments were angrier and more violent than normal. Frankly, the researchers cannot be blamed for this.[Non-game 52]
- December 17: A general of the U.S. military visits the Switchboard facility and receives a report from P.A.M. that Chinese stealth technology far outpaces that of the United States, and that the unidentified submarines spotted by U.S. monitoring stations a month prior may be from the Chinese "Ghost Fleet," an elite naval unit rumored to possess stealth-capable submarines. The general dismisses the intelligence as unsubstantiated, but P.A.M. responds by stating no actionable intelligence has come out of the Shaanxi Province of China since November 2072, except for a reported increase in the importation of complex polymers and key synthetic compounds. P.A.M. indicates that these are consistent with research into stealth technology on a large scale, but the general states that unless concrete evidence can be provided, such information is a rumor.
- December 20: West Tek ramps up agricultural mutation research at Huntersville.
- REPCONN Aerospace is bought out by RobCo Industries.
- January: The United States annexation of Canada is complete. Canadian protesters and rioters are shot on sight, and the Alaskan Pipeline swarms with American military units. Pictures of atrocities make their way to the United States, causing further unrest and protests.[Non-game 53]

- January 12: Splicing in several new gene sequences into their test virus, dogs are injected with batch 11-101a at West Tek. Although increased strength was noted, increased intelligence was not.[Non-game 55] Using batch 11-011, experiments are conducted on raccoons. The same results are noted, but the attempted escape of several infected raccoons causes Major Barnett to terminate the escape... and the test subjects. Two pairs of raccoons, however, are unaccounted for.[Non-game 56]
- February 16: After shuttering their agricultural research, West Tek starts human FEV mutation experiments at Huntersville.
- March 12: ATLAS tests in Appalachia yield first results.

- May 25: Experiments start to cause mutations at Huntersville.
- June: Power armor T-51b series development is completed, resulting in the first mass-produced T-51 power armor. The first power armor units are sent to China, where they perform flawlessly against Chinese forces. Enemy tanks and infantry are no match for the power armor and sometimes they even surrender to the advancing forces when they realize what they are against. As a result, the Chinese war effort begins to collapse, its resources and supply lines strained to the breaking point.[Non-game 59]
- July 4: Vault 76 is completed for the United States' tricentennial.
- August: Food and energy riots begin in major cities throughout the United States. Military units begin to be deployed in cities within the United States to contain rioters, and many temporary prisons are constructed. A state of emergency is declared, and martial law soon follows.[Non-game 60]
- August 20: ATLAS manages to create a wide variety of weather, warranting further investment of public funds.
- September 8: First super mutants emerge at Huntersville.
- October 4: At West Tek, fifteen chimpanzees are infected with batch 11-111. The most successful test to date, growth, and immunities in the chimpanzees surpass all other subjects to date.

- October 3: Automation riots begin. Faced with forced relocation the residents of Welch rebel against AMS. The rioting spreads to anything related to the local mining companies after the years of maltreatment. News of the town's rebellion spread across Appalachia, disfranchised mine workers across the region began to occupy company properties across the region. With the rebellion and property damage the Governor called in the National Guard and the local mining companies called in "independent contractors" to restore order. The violence began after AMS tried to dismantle people's homes to get to the Ultracite, the minors then deciding to strike before the mining companies decide to wipe them out completely. The miners called a meeting deciding to split into two groups, one, Mick Flanagan's to go and secure the Rockhound, the other O'Conner's to go to Bramwell to destroy the Mega Mansions of the wealthy industrialists who own the mines.
- October 10: Captain Roger Maxson and his men discover that the scientists at Mariposa have been using "military volunteers" (military prisoners who didn't have their brains removed for use in robobrains) as test subjects in their experiments. Morale in the base breaks down, and in light of the mental breakdown of Colonel Robert Spindel stationed at the base, Maxson's men turn to him for leadership.[Non-game 68]
