Casualties are estimated to be in the hundreds of thousands with infrastructure damage within a bounded range of effect of 1 to 3 miles. In this scenario a 10-kiloton improvised nuclear device is smuggled into the center of a large metropolitan city inside a delivery van and detonated. As a reference, the Hiroshima bomb was 12-KT and the Nagasaki bomb was 22-KT. The United States National Planning Attack Scenarios have identified the detonation of a 10-Kiloton (KT) Improvised Nuclear Device as the most likely incident of a nuclear bomb exploding within this country. At Hardened Structures we use only Military Grade NBC air filtering systems, blast doors, blast valves and other shelter components. Protection against the penetration of chemical, biological and radiological weapons is achieved by constant positive internal air pressure maintained by artificially filtered ventilation and air-locks. The extent of protection for private civilian underground bomb shelters will, in general, be determined by Blast Overpressure measured in “Bars”, (where 1 Bar equals 15 psi of applied Blast Overpressure) and initial radiation mitigation.

In addition, with the ever increasing importance of having EMP (Electro-Magnetic pulse) protection of Bomb Shelters, and other “HARDENED” structures, we provide State of the Art EMP mitigation both in terms of Bomb Shelter design engineering, which incorporates EMP shielding, and the usage of specialized EMP components. Although the design and dimensions are principally determined for nuclear weapons it can be established that a good underground nuclear bomb shelter also offers excellent protection against chemical, biological and conventional weapons along with most types of WMD’s. Also known as Weapons of Mass Destruction or WMD’s.

At Hardened Structures we design our civilian underground Bomb Shelters primarily for nuclear weapons of medium to large size but also secondary for chemical, biological and radiological dispersion devices and conventional weapons.
