By Spartan Survival Systems, Inc
USA Bunker Company was founded by two U.S. military veterans to design and build underground bunkers and saferooms that provide the best protection possible in the event of a natural or manmade disaster. Tapping into extensive experience in overseas combat and law enforcement as well as welding and fabrication, our team goes beyond designing and building your bunker, providing detailed guidance on set up, stocking, and use to help ensure your family’s survival.
We provide both standard and fully customized designs and complete installation for underground bunkers, saferooms, security features for buildings, and off-grid property. Contact our team today. We have seen what disasters can do to communities and we take emergency preparedness – and your privacy – seriously.
Designed and engineered to withstand major blast pressures and fallout from conventional nuclear bombs
Designed to withstand and protect from all fallout and radiation, much like our bomb shelters.
Designed to protect people and belongings from natural disasters, severe weather events, and human security threats.
Our fire shelters protect from heat, flames, and smoke when wildfires threaten your family and your property.
Every part and system of our bunkers is designed, manufactured, and installed with your safety in mind and specifically for the purpose for which it is intended.
Our air system fail safe and water control by Spartan Survival Systems offers a unique design to better manage your systems for maintenance and liability. This allows you to access all moving parts of your air system to insure proper function over the years.
We do not use marine grade "boat" doors. We use specialty doors designed and manufactured in the USA by Spartan Survival Systems specifically for bunkers and saferooms. These doors are heavy duty steel, air/gas/water-tight, with the security features required for an emergency shelter.
Our escape shafts are hidden under the surface with low profile springs to assist opening rather than sand-covered models that make escape difficult and dangerous. Each escape tunnel is fitted with a 90-degree bend to protect from radiation. This allows you to quickly access your hatch and escape if necessary.

Average price for a fully equipped bunker ranges from $35,000 and up for full NBC/Blast protection. Basic security threat shelters will run much less.
Yes, we have partnerships with the companies providing every aspect of our bunker business, including fabrication, system design, and installation. Our installation team is comprised of highly experienced, full-time workers who provide expert installation and a lifetime warranty on your bunker.
Yes, we can ship your bunker parts and systems anywhere in the world for your private installation. Our experts will gladly provide guidance and answer questions for your installer.
Our average shelter is 4' ground cover, but our round blast shelters can exceed 40' if desired. However, to get the maximum protection from fall out, 4' is needed, but the get maximum for blast on our round shelters, ground cover needs to match the diameter. A 10' diameter shelter would need 10' ground cover.
No, we do not offer inhouse financing. We recommend you shop around for financing, as banks will not give anyone a loan for a bunker, so you will need to get a personal loan, Equity, or contact a loan specialist with your needs.

We plan and design our bunkers according to guidelines specified by TACDA Academy Civil Defense Basics. See below:
Underground fallout shelters provide much better protection than basement shelters. Four feet of soil overhead will provide a PF greater than 1000. Good underground fallout shelter entrances should be between 30 and 48 inches in diameter and should have a total length of 22 feet or more. The best attenuation is reached if each leg of the L shaped entrance is 11 feet in length or greater.
Blast shelters should be built with arched ceilings. Flat-topped shelters will not carry the dirt load at those depths, and could fail catastrophically under the additional load from large over-pressures. Shelters in areas near heavy blast targets should be buried at twice their diameter. This depth of cover provides an ‘earth arching’ effect. The full earth arching effect will provide the shelter with approximately 200 psi of overpressure protection. A 10-ft. diameter shelter should be placed into a 20-ft. deep hole. A 9-ft. diameter shelter should be placed into an 18 ft. deep hole. This level of protection provides survivability at 1/2 mile from ground zero of a one-megaton yield ground burst.
The concept of building shelters from corrugated steel tanks was conceived by scientists and engineers at Oak Ridge National Laboratory (ORNL), and actually tested under blast conditions to 200 psi.
This type blast shelter would also provide protection from the ‘initial radiation’ which otherwise is lethal within 1 1/2 mile range of the detonation. Shielding, however, must be placed into the horizontal runs of the entrances to capture the neutrons from the initial radiation. The overhead shielding for initial radiation requires 8 ft. of cover.
Outside of the 1-mile radius of the blast, initial radiation is not an issue. Residual radiation (fallout) is easily attenuated with as little as 4 ft. of dirt cover overhead.
