The existence of this electromagnetic pulse has been known since the 1940’s.It was when the nuclear weapons were being developed and tested.However, the effects of an EMP bomb were not fully known until 1962 because of lack of data. At that time, the
In 1963, the Atmospheric Test Ban Treaty was signed by the
In 1998, David Schriner, a former civilian electrical engineer for the US Navy, told the Congress that he spent $US500 to buy automobile ignition coils, batteries, fuel pumps and various used hardware in his basement to build an e-bomb. In one week, he built an e-bomb that could make a running car hiccup at 15 meters by overloading its electrical component. So, the Congress agreed to give Schriner a million-dollar contract to see if he could build a truly effective e-bomb out of readily available materials. This proves that an e-bomb is a lot easier to build than a nuclear bomb, and they don't have to be delivered by very high technology missiles.
In 2000, British scientists at Matra Bae Dynamics(British Defence Firm) developed a non-explosive artillery shell serving as an E-bomb that could destroy electrical and electronic systems for miles. This E-bomb uses radio frequencies to destroy enemy’s electronics.
