The Enclave was comprised of members of the government, Joint Chiefs, and successful scientists. Research initiatives of the entity included those centered on power armor, rocketry, and energy weapon prototypes. During the Resource Wars, members of the Enclave made contingency plans in case of nuclear war, included securing installations such as the presidential oil rig and congressional bunker. In March 2077, the president of the United States retreated to the oil rig, resulting in news outlets such as the Boston Bugle reporting the action "giving credence to the long-running rumors of a secret, militarized shadow government, known as the Enclave."
During the Great War, government officials fled to the Appalachian bunker. Those who were members of the Enclave were allowed entrance and those who were not were killed. The military locked Enclave members out of their systems, and the bunker was unable to reach Raven Rock or Poseidon locations by radio. Without the ability to contact the president or Raven Rock, the leadership of the Appalachian Enclave fell to the Secretary of Agriculture Thomas Eckhart after the death of the Secretaries of the Interior and Treasury.
Led by President Dick Richardson and Vice President Daniel Bird, the Enclave contingent on the West Coast of the former United States established facilities in addition to the oil rig, such as the Camp Navarro military base. With a limited range, vertibirds were able to refuel at the isolated Navarro location. Enclave Control Company maintained perimeter defense of the facility. Additional outposts were located throughout the former state of California. Specialized units such as the Secret Service were tasked with protecting specific interests.
A group of scattered veterans living in the Mojave Wasteland after the destruction of the oil rig. The group utilized a bunker to stash their equipment and vertibird, continuing their attempt to integrate unnoticed into the New California Republic. The surviving members settled near New Vegas, and remnants will reminisce about a time where the Enclave gave the group purpose, and that their goals were always focused on trying to civilize things regardless of the outcome.
↑The Chosen One: "You're the President of what United States?" Dick Richardson: "I am the elected representative of the people. The United States does still exist. God bless us, every one. We've just had to adapt in order to survive after the war." (Dick Richardson's dialogue)
↑Courier: "What are you talking about?" Arcade Gannon: "I wasn't always with the Followers, or with the NCR. My late father was an officer in a group called the Enclave, a remnant of America's Pre-War government. Memories being short around here, not a whole lot of people remember them. But they did bad things. Terrorized communities, kidnapped people. Eventually, someone stopped them. I was born a few years later at a military base on the coast, a place called Navarro." (Arcade Gannon's dialogue)
↑MODUS: "The Enclave has counted Presidents, members of the Joints Chiefs, and prize-winning scientists among our membership." (MODUS' dialogue)
↑Arcade Gannon: "I've read about REPCONN. I think they did some work with the... the government before the war. Rockets and some energy weapon prototypes, I think." (Arcade Gannon's dialogue)
↑Chosen One: "Where is the Enclave main base located?" Central computer for Navarro: "Searching... Accessing geographical maps... Data acquired. Enclave headquarters is located 175 miles off of the coast of California in the Pacific ocean. Coordinates are 37 degrees 18 minutes north latitude by 120 degrees 7 minutes west longitude." (Navarro central computer)
↑MODUS: "This space was to be the beating heart of the Enclave's master plan. Today, it's storage. So much for the plans of great men."
↑Lone Wanderer: "Where did you come from?" John Henry Eden: "The ZAX series of computers was introduced in the years preceding the war. The government installed many of them to help automate various systems. This facility was designed for Continuity of Government, in the event that a catastrophe occurred. My terminal was installed to oversee the basic functions of the facility, and to act as a relay between other installations around the country. Data was acquired, analyzed, and stored. In the decades following the war, I watched as the remnants of the government retreated to the West Coast." (John Henry Eden's dialogue)
↑Whitley: "Eyebot Duraframe Subject E is both the prototype, and the last functional model in this test group. I was prepared to make several significant upgrades to the machines. However, as the project was canceled and all Duraframe assets are being diverted to Hellfire Armor, I am sending this model to the Navarro outpost. If you are listening to this log from one of our Enclave Outposts in Chicago, give this unit whatever repairs it needs so it can continue to Navarro." (ED-E's dialogue)
↑Chosen One: "Yeah, okay. How do I find them?" AHS-9: "The Enclave are a remnant of the past - a neurodyne that has yet to be aligned. They have hidden bases all over the shards of old California, and their strongest stronghold is off to the west, over the waters." (AHS-9's dialogue)
↑The Courier: "Where did the Enclave go?" Arcade Gannon: "A lot of different places. I only know what I was told. Some of them were cut down by the NCR and the Brotherhood. Some of them went east. My mother never told me what happened to my father, but she and I went south with some others and integrated into the NCR. When the NCR learned that Enclave personnel had integrated, we kept moving to the fringes. It's one of the reasons why I wound up out here." (Arcade Gannon's dialogue)
↑Courier: "What is this place?" Judah Kreger: "This was a minor refueling station for vertibirds. It seemed an appropriate place to stash our equipment if we ever needed. I'm surprised this place hasn't fallen apart. When I put it into standby mode, I expected to return to it within a few years, not decades." (Judah Kreger's dialogue)
↑Arcade Gannon: "Judah Kreger is the glue that's kept us all together over the years, and with good reason. Anyone who can command Moreno and Johnson in the same unit without somebody getting fragged is one hell of a leader. Kreger was polite and kind, but never warm. He always did his best to make me feel welcome in the group. I think he did it out of a sense of loyalty to my father. Loyalty means a lot to Judah. Not loyalty to the Enclave, or even the ideals they fought for, but to the people who served with him." (Arcade Gannon's dialogue)
↑Judah Kreger: "I miss those days sometimes. We all had a purpose, you know? I admit that some of the folks in charge were pretty ruthless. The rest of us, though - we were just trying to civilize things. The NCR was still new and it didn't look like they'd last all that long. Then, we lost the oil rig and shortly after that, the base at Navarro. Nobody left except us Remnants." (Judah Kreger's dialogue)
↑Reactor Maintenance and Repair Robot control terminal: "List other stations" "Searching Comlinks…Searching… Iron Mountain…Offline, NORAD…Offline, SAC…Offline. Searching PoseidoNet… --More?--" "More" "Active PoseidoNet Stations: Atomic Powerplant #5, Navarro Refinery, Control Station ENCLAVE, ENCLAVE Vault-Research Control... AccessDenied"
↑Sole Survivor: "You were a soldier? With what army?" Brian Richter: "They called themselves the Enclave. They were a force to be reckoned with in their day, but now... well, it's been a long time since then. I serve Atom now." (Richter's dialogue)
↑Burham Springs design documents, p. 5: "Government decision makers order the dumping of radioactive waste into Eagle Rock's lower mines. Enclave politicos help secure a contract for Poseidon Energy to develop and use their AGRICOLA mining robots in the operation of the dumping ground. Not surprisingly, the AGRICOLA lab turns out to be a pretty good bunker as well."
↑Fallout 3 Official Game Guide Game of the Year Edition p. 41: "The Enclave: In the recent past, the Enclave—the remains of the United States government—were evacuated to an oil rig off the coast of California. Little is known about what happened to these forces, although the country has a new commander-in-chief: President John Henry Eden." (Fallout 3 Official Game Guide faction profiles)
↑Fallout: Wasteland Warfare Roleplaying Guide pg. 16: "The Enclave is greatly diminished in power, yet has still managed to survive. Its influence stretches across the country, and there is still many hidden Enclave bunkers positioned throughout the Wasteland. This is the technologically advanced military force that the Enclave uses to carry out its operations in the Wasteland. They were, at one time, the most advanced fighting force on this planet with their soldiers in Power Armor wielding energy weapons. The Department of the Army also fields an Air Force made up of Vertibirds and a Navy comprised of a few ancient battleships from the pre-war era."
