Couple transforms former nuclear silo into a bunker 60 meters deep to survive for up to 2 years in the event of societal collapse, while over 20 million Americans stockpile food, water, weapons, and energy in anticipation of the worst.

The underground routine of extreme preparation enthusiasts shows how fear, technology, and survival intersect in a culture that gained strength in the United States and transformed bunkers into a symbol of autonomy.

Preparing for long periods without access to supermarkets, energy, treated water, or public services is no longer a behavior restricted to isolated groups in the United States.

Reuters reported, based on researchers on the subject, that the number of preppers in the country reached about 20 million, in a movement associated with natural disasters, political instability, pandemic, and distrust in emergency response systems.

The case of the underground bunker linked to the former Atlas F silo in Kansas circulates on social media as an extreme example of this style of preparation.

Confirmed data indicate that the structure is located in Wilson, was purchased by Matthew Fulkerson in 2013, and today operates as Atlas Ad Astra, an enterprise with guided tours, camping, underground accommodation, and an educational project focused on Cold War history and resilience technologies.

The depth of the silo is 176 feet, about 54 meters.

In informal reports, the measurement appears rounded to nearly 60 meters.

The space was part of an intercontinental missile base built between 1959 and 1961 and deactivated in 1965, according to Kansas state tourist material.

Why the prepper movement grew in the United States

The term prepper refers to people who organize resources to face crises without immediately relying on external help.

In practice, this can include stocks of water, food, medicines, tools, generators, solar panels, filters, radios, and family evacuation plans.

This behavior appears in varying degrees.

There are families that maintain only basic supplies for a few days, as recommended by civil defense agencies, and there are groups that plan for months of autonomy.

In more extreme cases, preparation involves remote properties, underground shelters, and proprietary security systems.

Fema, the American federal emergency management agency, recorded in 2023 that 51% of adults in the United States said they were prepared for a disaster.

The same survey showed that 57% reported having taken three or more preparation measures in the previous year, such as assembling supplies, creating plans, protecting documents, or registering alerts.

These numbers do not mean that everyone is a prepper in the most well-known sense of the term.

Even so, they show that the idea of domestic preparedness has come to occupy a broader space in the American public debate, especially after events capable of disrupting routines, supply chains, and essential services.

Rule of Three Defines Survival Priorities

Among survivalists, a recurring reference is the so-called rule of three.

It summarizes priorities in a risk situation: a few minutes without air can be fatal, a few days without water endanger life, and lack of food for weeks compromises survival.

The rule is not an exact medical formula.

Its use is practical: it helps organize decisions in emergencies and defines what should come first in a survival kit.

Shelter, breathable air, potable water, food, communication, and healthcare are treated as stages of the same plan.

With this logic, water usually occupies a central place.

Without a safe source or filtration system, the food stock loses utility.

Energy also becomes strategic because it keeps ventilation, heating, refrigeration, lighting, and communication functioning during a prolonged interruption.

What the Old Atlas F Silo in Kansas is Like

The Atlas Ad Astra occupies an old Cold War missile base.

According to the official website of the venture, the site offers a one-hour guided tour of the old underground complex, with access to the vertical silo that housed an intercontinental ballistic missile.

The original structure was designed for military, not residential, use.

The complex had control areas, tunnels, reinforced doors, ventilation systems, and operational spaces intended for the military responsible for launching and maintaining the missile.

A report published by the Kansas tourism authority states that the base had large containment doors, an elevator to bring the rocket to the surface, and thick layers of concrete.

The same material informs that the construction had concrete up to nine feet thick on the surface and blast doors three feet thick.

Today, part of the facility has been adapted to receive visitors.

The Atlas Ad Astra website informs that there is accommodation in the old launch control center, as well as areas for tents, trailers, and recreational vehicles.

There are also expansion plans with additional infrastructure, such as RV hookups and high-speed internet.

Underground Bunker Requires Energy, Water, and Redundancy

A functional bunker is not just about thick walls and heavy doors.

To remain habitable for long periods, an underground structure needs energy, water, ventilation, humidity control, stored food, waste disposal, and communication.

Redundancy is a frequent principle in this type of planning.

When one energy source fails, another needs to be available.

If a filter stops working, the water supply or a second treatment system reduces the risk of total interruption.

In modern structures, this logic may involve generators, batteries, solar panels, long-lasting food, radios, sensors, cameras, and internal communication networks.

Each item has a specific function, but the set only operates efficiently if there is maintenance, testing, and periodic replacement.

The cost and complexity vary according to the project.

A simple shelter can be designed for a few days.

An adapted silo requires construction, inspections, adequate ventilation, structural control, and permanent solutions to transform a military space into a safe environment for stays.

Isolation in a bunker also affects the routine

Underground life imposes challenges beyond infrastructure.

Enclosed spaces without natural light can affect sleep, time orientation, and well-being, especially when the stay extends for many days.

For this reason, bunker projects often include resources that simulate surface aspects.

Programmed lighting, social environments, domestic decoration, screens that mimic windows, and leisure areas reduce the feeling of confinement.

These measures do not eliminate the effects of isolation, but they are part of the habitability planning.

In an emergency scenario, continuous coexistence in a closed environment may require routine rules, division of tasks, and communication channels with the outside world.

In the case of Atlas Ad Astra, the current proposal is not officially presented as a permanent residence for social collapse.

The enterprise describes itself as a space for tourism, lodging, education, and historical preservation linked to the former Atlas F base.

Prepper communities share emergency techniques

The image of the solitary prepper exists, but it does not summarize the movement.

Reuters showed that the American prepper culture has diversified in recent years and has come to bring together people with different political, social, and economic profiles.

Preparation also appears in fairs, courses, local groups, and knowledge exchange communities.

In these networks, participants share techniques for food preservation, first aid, gardening, water filtration, radio communication, and emergency response.

According to Chris Ellis, a researcher cited by Reuters, a prepper can be defined as someone capable of living for a month without external support.

He told the agency that the central question to understand this audience is whether the person feels secure.

This point helps differentiate domestic prevention from extreme preparation.

In one case, the person organizes resources for a flood, blackout, or storm.

In the other, they start structuring part of their life around the hypothesis of prolonged failure of institutions and services.

Bunkers reflect the perception of modern risk

The interest in underground shelters is linked to how a portion of the population perceives contemporary risks.

Events like pandemics, fires, hurricanes, blackouts, and communication network interruptions have reinforced the discussion about domestic autonomy and emergency response.

Fema treats preparation as a public safety issue and encourages measures such as assembling supplies, creating family communication plans, protecting documents, and knowing evacuation routes.

The prepper movement expands this logic and, in some cases, takes preparation to more complex and expensive levels.

In the old Kansas silo, the appeal lies in the combination of military history, underground engineering, and curiosity about survival.

The same structure that once served a nuclear program now receives visitors interested in understanding how a base built to operate in extreme situations functioned.
