DALLAS, TX, January 15, 2018 — Walton McCarthy, Senior Engineer at NORAD Shelter Systems LLC, understands both  the big picture and the minute details of nuclear attack protection.

The Hawaii ICBM false alarm triggered intense interest in how bomb shelters work. “Survival shelter” strategies are often poorly planned and based on myths. Old civil defense shelters will not adequately protect people from nuclear war.

McCarthy has been engineering and building bomb shelters for 40 years. His book “Principles of Protection: U. S. Handbook of NBC Weapon Fundamentals and Shelter Engineering Design Standards” is now in its 6th edition. Created with a team of university and government experts, “Principles of Protection” is considered “the bible” of the bomb shelter industry.

News organizations seeking expert nuclear war protection and bomb shelter information can request an interview with Mr. McCarthy by calling +1 (972) 913-6882 to schedule an appointment.

NORAD Shelter Systems LLC is a Texas defense company that engineers and installs  bomb shelters worldwide.

12 Underground Shelter Deceptions That Can Get You Killed


Press Release

12 Underground Shelter Deceptions That Can Get You Killed — There are no federal or state agencies protecting consumers from deceptive underground shelter nuclear protection claims.

Garland, TX, August 2, 2017:  NORAD Shelter Systems LLC® today published an informative guide warning consumers about misleading nuclear shelter protection claims. 12 Underground Shelter Deceptions That Can Get You Killed is now available on the website. Because the nuclear shelter industry is neither regulated nor subject to certifications, consumers must be knowledgeable about how life-saving components work. Consumers can use this knowledge to ask the right questions when shopping for underground nuclear protection.

NORAD Principle Engineer Walton McCarthy (Wikipedia) said “Underground shelter manufacturers can claim anything with no data to support their deceptive protection claims.” One deception he often sees is shelter companies claiming complete nuclear, biological and chemical (NBC) air filtration. Cheap  Nuclear-Biological-Chemical (NBC) air filters contain too little TEDA carbon to filter NBC contaminants. They leave shelter owners exposed to radiological, biological and chemical dangers. A $2,500 NBC air filter system could not possibly contain enough TEDA carbon to work, unless the manufacturer is selling it at a steep loss. Consumers can learn to ask about TEDA carbon residence time for a given air volume to ensure the shelter’s air will be  filtered of deadly agents.

McCarthy says that many shelter manufacturers claim that zero radiation enters their shelters from overhead, air ducts, and entranceways, which is impossible. The entranceway is the largest source of radiation entering a shelter. Significant radiation can also enter the shelter through the air ducts and from overhead. Radiation entering the shelter’s entranceway is a function of the entranceway’s size and geometry. Anyone can use NORAD’s Entranceway Radiation Calculator to determine the radiation amount that will enter the shelter given a 500 KT air burst which is the type and size weapon chosen by the NBC committee. A good entranceway  design will not allow more than 10 rems into the shelter. Most shelters on the market today allow a sickening and even deadly amount of  radiation to enter the shelter through the entranceway.  Consumers should always ask:  “How far is the shelter designed to be from ground zero for a given size weapon and what are the doses inside the shelter?”

Readers will also learn that there is no such thing as a FEMA certified shelter since FEMA is not a certifying agency. A 99.97% HEPA air filter is not good enough to protect people from biological weapons; and many more deceptions that can get a shelter buyer killed.

NORAD is publishing another article called Electromagnetic Pulse (EMP) Deceptions That Can Get You Killed in the next month.



NORAD is a Texas Engineering and manufacturing company making the only RATED underground shelter in the U.S.  providing performance data and protection from nuclear, biological, EMP and financial collapse.

Winegard Group Acquisition


Defense Industry Holding Company Acquires Military Shelters Consulting Group and NORAD Shelter Systems LLC®

GARLAND, TX JUNE 16, 2016 – The Winegard Group has acquired Military Shelter Consulting Group (MSCG) and various US Patents, Patents Pending, and intellectual property from mechanical engineer Walton W. McCarthy under a long term agreement. With this package, Winegard has formed the new engineering and manufacturing company NORAD Shelter Systems LLC®.

NORAD Shelter Systems will manufacturer, deliver and install underground nuclear and tornado shelters based on McCarthy’s S-Series bomb shelter designs. The S-Series underground nuclear shelters are the only “rated” shelter in the United States. “Rated” shelters include proven performance ratings.

“A nuclear shelter must be designed based on a radiation design dose, a pressure rating and a structural warranty,” McCarthy said. “Otherwise, how do you know you’re being protected?”

NORAD S-Series shelters come with published performance data documenting:

  • life-support system specifications, showing how life support systems last 1 year or more
  • pressure ratings, showing how the shelter and the people inside are protected from bomb blast pressure
  • radiation design dose, showing how much radiation protection the design and installation methods offer
  • distance from ground zero ratings, showing protection levels based on distance from nuclear blasts
  • a structural warranty backed by technology and performance data


“The NORAD S-SERIES underground nuclear shelters are long-term solutions with published radiation design dose, pressure, and ground zero distance data, with incredibly strong warranties,” McCarthy explained.


McCarthy said that the market is saturated with “survival shelters,” which are cheaply made and poorly warrantied. The NORAD S-Series shelter is not a “survival shelter.”


“Virtually all so-called nuclear shelters on the market today are just cheap ‘survival shelters.’ A survival shelter is a short-term underground structure that has little or no published performance data. It has no published Radiation Design Dose from overhead or from the entranceway, no published ratings for pressure, and no published internal radiation doses that shelterists can be expected to receive. A ‘survival shelter’ does not list the distance from ground zero for which the shelter is designed. Survival shelters have weak or no warranties. This type of shelter has a short-term air filtration system and meets virtually no commercial, military or manufacturing standards.”

“Survival shelters are cheap,” said McCarthy, “and they don’t really provide adequate protection from any of the threats we face. They don’t really provide protection from blast pressure and radiation. They don’t really provide protection from EMP and biochemical warfare. NORAD S-Series shelters provide protection from all of these threats, with proven performance data to back up NORAD’s claims.”

Mr. McCarthy has designed, engineered, manufactured and installed more than 1,400 shelters since 1977. He is the author of Principles of Protection: The U.S. Handbook of NBC Weapon Fundamentals and Shelter Engineering Design Standards, 6th edition, 2013, Brown Books, which defines scores of engineering standards for proper shelter design protection from nuclear blast, radiation, biochemical threats and EMP.

McCarthy’s book was written with a committee of experts from the US Department of Energy, US Department of Defense, Strategic Applications International, Nuclear Engineering Laboratory from the University of Illinois, Oak Ridge National Laboratories, Chemical Division of Edgewood Arsenal, Brookhaven National Laboratory, US Defense Nuclear Agency and the US National Bureau of Standards.

PRINCIPLES OF PROTECTION details shelter design requirements for sample weapon sizes and distances from ground zero. Any properly-educated engineer can use this data to establish the radiation design dose for any underground shelter. NORAD will be publishing a website calculator which anyone can use to determine any shelter’s radiation design dose.

PRINCIPLES OF PROTECTION (POP) is available on Amazon. No other book published has these weapon effects listed. POP has been used by architects and engineers around the world since 1991. Winegard announced it is pleased to acquire the culmination of McCarthy’s 40 years of designing bomb shelters.

In addition to defining radiation standards for shelter overhead shielding, entranceway shielding, and air ducts never before published, it includes proper standards to use in shelter design from multiple sources including the American Boat and Yacht Council (ABYC), American National Standards Institute (ANSI), American Petroleum Institute (API), American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), American Society of Mechanical Engineers (ASME), American Society for Testing Materials (ASTM), U.S. Department of Defense Military Standards (MIL) and Steel Tank Institute, NACE International – The Corrosion Society (STI and NACE), National Electric Code (NEC) and National Sanitation Foundation (NSF).

NORAD will manufacture the S-Series underground Steel shelters in two Fort Worth facilities with almost 200,000 square feet serviced by overhead cranes. NORAD Shelters will fall under the Department of Defense ITAR (International Traffic in Arms Regulations) rules and require export licenses for deliveries outside of the United States.

The S-Series Military models includes an internal diesel generator that is EMP shielded to the MIL-188-125 providing a one year off-grid duration using only 800 gallon of diesel fuel. The S-Series air filtration system uses a Bag In Bag Out (BIBO) nuclear, biological and chemical air filtration system so filter trays can be changed without coming into contact with the filter elements.

The S-Series shelters have a TRS (total rems in shelter) Rating of 4 rems @ 10 psi. They  use no concrete and are re-deployable. The shelters are designed to resist hydrostatic pressure in high water tables without tie downs so they can resist strong ground shock including an 8.5 Richter earthquake with no damage.

The underground S-Series steel shelter has a formal cathodic protection system using dielectric epoxy and magnesium anodes. The system diverts all corrosion to the anodes surrounding the shelter, away from the hull, allowing NORAD to support a constant pressure rating throughout the 30 to 50 year structural warranty.

The bomb shelter’s air manifolds are at ground level. They have a low profile and low angle of incidence domes only 4 inches above ground which are engineered to resist heavy flying debris up to 350 mph.

A Winegard representative said S-Series shelters would be manufactured starting in April of 2016. Mr. McCarthy has been retained as the Principle Engineer for NORAD Shelter Systems LLC®.

Dallas TX, January 26, 2016 — When it comes to preparing for global calamity, NORAD Shelter Systems LLC®, a Texas blast shelter company, Principle Engineer Walton McCarthy is a world-class expert. He has designed and installed more than 1,400 underground shelters over 40 years and published several articles about how to survive nuclear, biological or chemical attacks. But in the cyber age there are more threats to prepare for and a man like Mr. McCarthy is not one to be unprepared. His latest article, “Modern Farm Self-Sufficiency After an EMP or Cyber Attack” is a comprehensive tutorial for those who are not content to leave their lives in the hands of fate or luck.

No Power For Anything

In this article, Mr. Walton, describes the potential implications of a complete power loss for the entire country or large portions of it. The lack of electricity will prevent any farm of any size from operating as running water, waste disposal, fuel pumps, central heating, food delivery trucks and heating for homes will all be unavailable. The article provides specific guidance about how the modern farm can be self-sufficient without the power grid. But how could any single event make electricity unavailable?

What Is An EMP?

An electromagnetic pulse is a short burst of electromagnetic energy. These pulses can come from natural sources like lightening, or even the sun. Man-made sources are generally weapons that are both nuclear and non-nuclear. EMP interference is generally disruptive or damaging to electronic equipment, and at higher energy levels a powerful EMP event such as a lightning strike can damage physical objects such as buildings and aircraft structures. Protection from EMP”s cannot be accomplished by surge protectors.

POST EMP FARMINGPreparation Is The Only Possibility

The article describes steps farmers can take now to prepare for this eventuality. McCarthy focuses his attention on farming, because without food, any type of long-term survival or sustainability will be out of the question.

Overall, the tutorial provides a handy guide to preparing, and ultimately avoiding, the inevitable chaos that will arise from an EMP attack. The guide provides a host of useful facts and figures, backed up with scientific studies, and takes into account a number of “practicalities” for crop farming, including machinery, weeds, insect and disease management.

The S16x16 Bomb Shelter

Press Release S16x16: Groups Worried about Economic Collapse and North Korea’s Nukes Now Have Military Underground Shelter Protection Adapted for Civilians Using the S16x16 Bomb Shelter

S16x16 Bomb Shelter Floor Plan 1S16x16 bomb shelter interiorDallas, TX, September 26, 2016 — Groups seeking military-level underground shelter protection can now purchase the NORAD S16x16 bomb shelter which provides 8 people underground, off-grid protection for one year. At 0.9 miles from two 100 kiloton nuclear blasts a person inside the S16x16 bomb shelter would have the same chance of injury as a person living normally in peacetime.

[updated January 23, 2017 Changed model spelling; added commercial designation; removed S16x16G and S16x16G-MIL; clarified protections offered]

Families and groups seeking military-level underground shelter protection can now purchase the NORAD S16x16 commercial bomb shelter which provides 8 people underground, off-grid protection for one year.

Texas bomb shelter company NORAD Shelter Systems LLC recently introduced a smaller underground steel blast shelter for use by 6 to 8 people. The S16x16 is a commercial product suitable for multiple uses and can be shared by two or more families. The S16x16 shelter runs on solar power rather than a military-required EMP-shielded internal diesel generator. Upgraded with the NBC Package the S16x16 allows up to 8 people the same protection from war, terrorism, violence and natural disaster that the NORAD Military shelters provide for larger military troop sheltering. The shelter offers one-year off-grid protection. The actual duration is theoretically unlimited using solar power. The structure is warrantied against failure for from 30 to 50 years.

Protection from Financial Collapse and Power Grid Failure Social Effects

NORAD’s civilian customers seek protection from financial collapse which would deprive millions of Americans of electrical power. They also seek protection from a nuclear explosion, fallout and the EMP (electromagnetic pulse) a nuclear bomb can cause. An EMP attack could wipe out the power grid and create severe economic and social collapse. Fears are particularly strong about some radical small country like North Korea sending nuclear missiles to America either from land to land or from ship to land.

Much More Interior Space

While many shelters are cramped and dark, but even claustrophobic people feel fine in the S16x16 civilian underground shelter. The 256 square foot space offers the space of a medium sized one-car garage. The S-Series shelters offer much more usable space than many other shelters which use rounded “culvert drain” designs. The S16x16’s high sloped ceilings, vertical walls and in-wall storage provide superior usable space. Ceiling heights range from 8 to ten feet, much taller than average conventional ceilings. A 6 foot tall person has two to four feet of clearance overhead. Occupants can store 96 five-gallon food buckets and 400 rolls of toilet paper in the in-wall storage shelves so that none of the survival supplies clutter up the living area.

S16x16 Bomb Shelter Cross View 1Protection from Man-Made and Natural Disaster

Nuclear blast protection is documented in NORAD’s extensive performance data on its shelters. At 0.9 miles from two 100 kiloton nuclear blasts a person inside the S16x16 bomb shelter would have the same chance of injury as a person living normally in peacetime. The NBC air filters are “Bag In-Bag Out” so the people can change the air filter trays without coming into contact with NBC contamination. The NBC upgrade also includes a chemical warfare test port allowing occupants to test for dangerous agents without going outside. The package includes shielding mission essential equipment from the damaging frequencies of an electromagnetic pulse, whether from a high altitude nuclear explosion or a coronal mass ejection (solar flare). The S16x16 offers multiple protections from nuclear, biological, chemical threats, EMP, war, terrorism, storms, fires and floods. Multiple defenses make shelter security very difficult for intruders to defeat. Emergency escape hatches are available.

Spare Air Filtration Trays and Solar Panels

An enormous effort has gone into preparing for every situation the shelter occupants will face. The S16x16 bomb shelter’s solar energy system powers the stainless steel SEAM (Severe Environment Air Module) HEPA dust air filtration system. The NORAD S-Series NBC Package includes spare solar panels and air filtration trays. The spare solar panels are stored in an EMP-shielded vault to be used after an EMP attack disables the first panels. The spare air filtration trays are placed into the air filtration unit after a nuclear event causes the first trays to become “hot.”

S16x16 Bomb Shelter Exterior 1Conventional Plumbing

The shelter Plumbing Package includes conventional pressurized plumbing such as a flush toilet, two sinks, a fiberglass shower, septic removal and a leach field. The bathroom is under constant negative pressure to remove unpleasant smells. “People in the S16x16 bomb shelter do not have to live like cavemen,” said Darik McCarthy, NORAD Sales Engineer.

Cooking Package

The Cooking Package includes a microwave oven and methanol-powered cooking stove.

Kitchen, Bath and Bedroom Furniture

The Furniture Package includes two twin or queen bunk beds rated to 800 lbs. for a total of four mattresses. The bathroom and shower are enclosed in interior walls. The package includes a table, chairs and cabinets in addition to the in-wall storage. The package allows for normal living with hot and cold running water.

Solar Powered Battery Bank

The shelter’s solar system powers the battery bank, which in turn powers the shelter’s air filtration, water pump, sewage lift station, lights and radios, as well as occupants’ TV’s, computers and entertainment devices.

No Corrosion

The S16x16 is manufactured with a cathodic corrosion protection system allowing a 30-50 year structural warranty. Steel underground shelters without this level of corrosion protection weaken 3 to 5 % each year. NORAD’s incredibly strong shelters are designed to be buried under hundreds of thousands of pounds of earth pressure for 50 years without weakening.

S16x16 Production Date

NORAD announced that the S16x16 bomb shelter will go into production at the end of September 2016.
