Underground Bunker Sales & Installation

DEFCON Mfg Underground Bunker Steel StructureDEFCON Underground Mfg, crafts underground bunkers, bomb shelters and emergency shelters that are built with high quality plate steel and re-enforced structural metals. Your entire underground bomb shelter, with renowned durability, is extremely rigid and strong, unlike shelters from many of our competitors.  As extreme pressures are applied; the steel construction frame used in our engineering adds tremendous strength to the bunker while distributing weight and pressure across the entire are. We build them without structural “weak spots” and these underground bunkers will not collapse under weight or unexpected shifts in the surrounding areas.

Underground Bunker Bomb Shelter Security and Privacy ImageAt DEFCON Underground Manufacturing, privacy is one of our top priorities. We take a lot of care insuring that your privacy is kept. We do not keep location records after your Underground Bunker or Bomb Shelter is in the ground. We tarp all of our bunkers during shipping. DEFCON Underground MFG install teams will show up in uniforms and vehicles marked as a plumbing company to keep suspicions down. Our install teams will show up to do all excavation and site prep before the arrival of your Underground Bunker or Bomb Shelter. This allows us to get your Underground Bunker or Bomb Shelter in the ground away from prying eyes as soon as possible. The only records DEFCON Underground MFG keeps is for accounting purposes. You can even get a P.O. Box to have your correspondents sent to.

On almost any day, at any time, you can turn on the news and see a startling headline. Terror attacks and natural disasters have become a common occurrence. In locations and events where we used to feel safe, we now feel unsure and possibly unprepared. The time has come to be prepared. Plan for the unknown and unseen by building an underground shelter to protect you and your family.

Take a moment to imagine a terrorist bombing or natural disaster directly affecting you. Who is there to protect your family? Does someone rescue you and take you to a large, government bunker? The answer is no. It’s up to you to prepare for yourself. Not only is it your responsibility, it’s your right as a U.S. citizen. In 2006, FEMA released the National Planning Scenarios listing nuclear, biological, and chemical weapons as credible disasters that federal, state, and local municipalities should develop a preparedness plan for. A disaster shelter falls under this classification as a defensive arm against natural and man-made disasters in this government report. DEFCON shelters are considered an emergency structure that can be redeployed to another location; therefore you have the right to install them to protect yourself.

Don’t wait until it’s too late, give DEFCON Underground MFG a call and start the process of building an Underground Bunker or Bomb Shelter today!
