First successful test of a high-powered microwave weapon
According to Official Guinness Records,
The earliest recorded successful testing on of a high-powered microwave (HPM) weapon on electronic equipment occurred in April 1999 under the observation of the Joint Command and Control Warfare Center of San Antonio, Texas, USA. HPMs discharge a powerful energy pulse that destroys any electronics within its 300-m (984-ft) range, the aim being maximum disruption to any military or civilian power and electrical systems. The 'e-bomb' is still under development, as some of the unintended side-effects include the distruption of hospital equipment, pace-makers and any aircrafts flying in the region of the pulse. The 2 billion watts of electrical power that is released in the flash is equal to the amount of energy that the Hoover Dam creates in a day.
