S-Series Military Blast Shelter Model Performance Data Summary

NORAD Shelter Systems LLC® Military bomb shelters include features required to meet military specifications. These include a shelter hull with a TRS Rating for overpressure and internal radiation doses, nuclear blast protection, corrosion protection system, intruder defense protection, NBC EMP protection per MIL-188-125, plumbing, electricity, internal EMP Shielded diesel generator power, EMP Shielding per MIL-188-125 for all Mission Essential Equipment (MEE), electric lights, UV water sterilization, hot and cold running water, scanner and HAM radios, conventional toilet and septic, and furniture. NORAD Civilian bomb shelters share the Military model design including corrosion protection and intruder defenses. The performance data below refers to the NORAD Military bomb shelters. Once a Civilian bomb shelter is sufficiently upgraded to meet these requirements, it earns a -MIL Military model designation.

Using Bomb Shelters, People Can Be Prepared for Nuclear War

Between 2000 and 2010, presidents of the United States have signed 612 major disaster declarations for territories in the United States. This has averaged more than five major disasters each month, affecting many thousands of people who were unfamiliar with and/or unprepared for disasters.

Bomb Shelters by NORAD Shelter Systems LLC®

Texas Bomb Shelter, Commercial Tornado Shelter and Residential Tornado Shelter Company, Shipping Worldwide

NORAD Shelter Systems LLC® makes bomb shelters and tornado shelters in Garland, Texas. We ship bomb shelters worldwide with an export license from the U.S. Department of Defense. Our bomb shelters are articles listed under the United States Munitions List.

The S-Series Bomb Shelter

NORAD Shelter Systems LLC® designs, engineers, and installs the NORAD S-SERIES underground shelters. The S-Series bomb shelters protect occupants from numerous natural and man-made threats. The S-Series comes in four widths or models: S12 (12 ft. wide), S16 (16 ft. wide), S24 (24 ft. wide) and S30 (30 ft. wide). Lengths start at 16 ft. or 24 ft., depending on the model. Lengths extend in 8 ft. increments. For example, the S16x16 is a 16 ft. x 16 ft. solar-powered shelter. The S16x40 is a 16 ft. x 40 ft. shelter. Theoretically the S-Series shelters can be any length (in 8 ft. increments) so long as there is suitable ground for installation.

“A shelterist in the NORAD S-Series Shelter under heavy, direct effects from two 1-MT nuclear weapons, has at least the same probability of survival (99.7%) as a person living and working in peacetime.”

Military and Civilian Bomb Shelters

The S-Series shelters are classified as Military (“-MIL”) or Civilian. Only shelters meeting certain military and other manufacturing standards are “Military Shelters.” The hull, foundation and corrosion protection are the same in both Military and Civilian shelter models. Military bomb shelters have NBC protection, EMP shielding, an EMP-shielded internal generator, an electrical system, pressurized plumbing and a conventional septic system. The minimum Civilian configuration is the steel hull and foundation, a 68 degree entranceway and 30 in. diameter hatch, a solar power package, and HEPA air filtration. Civilian models can be solar powered whereas a Military model will always have an internal EMP-shielded diesel generator. Civilian models can be upgraded with Military features.

Blast Shelter Company

NORAD is a blast shelter company. We might use phrases like “we sell bomb shelters” in our informational material because we want people to find us. Technically, though, only “blast shelters” provide the engineering features required to be a military underground nuclear protection shelter. Our Military S-Series shelters are always “blast shelters.” Our Civilian S-Series shelters without the blast valve upgrade are “fallout shelters.” Civilian S-Series bomb shelters upgraded with the blast valves provide the same protection from nuclear blast and overpressure as our Military S-Series bomb shelters. Civilian bomb shelters upgraded with the NBC protection provide the same protection from nuclear fallout, biological weapons and chemical agents as our Military bomb shelters.

State of the Art Bomb Shelter Protection

Following on almost 40 years in bomb shelter design, the NORAD S-Series Bomb Shelter represents “State Of The Art” technology. The shelter hull shape allows 100% useful space for troops and individuals to operate in and the steel hull and steel foundation are equipped with a 30 to 50 year warrantied corrosion protection system. All military configuration bomb shelters have the EMP Shielding Package Option, are EMP Shielded to MIL-STD-188-125 and manufactured to numerous engineering standards. Strength and protection performance data is available to interested customers.
