Let us say the freighter ship launches a nuclear-armed Shahab-3 missile off the coast of the U.S. and the missile explodes 300 miles over Chicago. The nuclear detonation in space creates an electromagnetic pulse (EMP).
Gamma rays from the explosion, through the Compton Effect, generate three classes of disruptive electromagnetic pulses, which permanently destroy consumer electronics, the electronics in some automobiles and, most importantly, the hundreds of large transformers that distribute power throughout the U.S. All of our lights, refrigerators, water-pumping stations, TVs and radios stop running. We have no communication and no ability to provide food and water to 300 million Americans.
This is what is referred to as an EMP attack, and such an attack would effectively throw America back technologically into the early 19th century. It would require the Iranians to be able to produce a warhead as sophisticated as we expect the Russians or the Chinese to possess. But that is certainly attainable. Common sense would suggest that, absent food and water, the number of people who could die of deprivation and as a result of social breakdown might run well into the millions.
A successful EMP attack on the U.S. would have a dramatic effect on the country, to say the least. Even one that only affected part of the country would cripple the economy for years. Dropping nuclear weapons on or retaliating against whoever caused the attack would not help. And an EMP attack is not far-fetched.
Twice in the last eight years, in the Caspian Sea, the Iranians have tested their ability to launch ballistic missiles in a way to set off an EMP. The congressionally mandated EMP Commission, with some of America's finest scientists, has released its findings and issued two separate reports, the most recent in April, describing the devastating effects of such an attack on the U.S.
Theoretically, an EMP attack is devastating because of the unprecedented cascading failures of major infrastructures that could result. Because of America's heavy reliance on electricity and electronics, the impact would be far worse than on a country less advanced technologically. Graham and the commission see the potential for failure in the financial system, the system of distribution for food and water, medical care and trade and production.
It is possible for the functional outages to become mutually reinforcing until at some point the degradation of infrastructure could have irreversible effects on the country's ability to support its population."
Graham took the EMP debate out of the realm of science fiction by reminding the committee that as recently as May 1999, during the NATO bombing of Yugoslavia, Russian leaders threatened a U.S. congressional delegation with the specter of such an attack that would paralyze the U.S.
He also quoted James J. Shinn, assistant secretary of defense for Asian and Pacific Security, who two weeks ago told the same House committee that China's arms buildup includes exotic experiments with electromagnetic weapons that can devastate electronics with bursts of energy similar to those produced by a nuclear blast.
Recovery from a widespread EMP attack could take months or years, Graham warned. The fact that key components of the U.S. electrical grid are not even manufactured in America and must be ordered a year in advance from foreign suppliers suggests just how complicated and time-consuming recovery might be. The high state of automation within America's utilities further complicates recovery. There just might not be sufficient trained manpower available to get the job done in a timely way.
Structural tests have been completed on several papercrete formulas and Fuller claims the compressive strength of papercrete to be in the 140-160 lb./sq. inch range. A more useful measure of papercrete's properties is its stiffness - i.e. the extent to which it compresses under load. Its stiffness is many times less than that of concrete, but sufficient for the support of roof loads in some low-height buildings.
You mix the dry ingredients together with water to make a slurry. This slurry dries into hard blocks that are strong (260 psi compressive strength), lightweight, and an excellent insulator (R 2 per inch). Papercrete holds its shape even when wet. Except for the cement, all the ingredients are free or almost free, which makes papercrete a very inexpensive building material.
A continuously sealed metal barrier has proven to be very effective in preventing EM/HPM energy from reaching susceptible electronic or explosive components. Exterior packaging fabricated from plastic, wood or other fibre materials provides almost no protection form EM/HPM threats. The metal enclosure can be very thin provided there are no openings (tears, pin holes, doors, incomplete seams) that would allow microwaves to enter. Sealed barrier bags that incorporate a thin layer of aluminium foil and are primarily used to provide water vapour proof protection to an item, can add a great deal of resistance to EM/HPM penetration.

Cover everything with lots of dirt, plant a garden, and disguise one of the entrances as an outhouse. Succeed to astonish your neighbors by transporting large, unwieldly objects through said outhouse.

I found a site where you can order U.S. military manuals for bunker design/construction/warfare.
This is the best I could find in the last 3 years (!)
Does anyone know where I could download these online?

Have emergency escapes planned, and always have alternative measures for sit-x.
