ATLAS-I, also known as the Trestle, near Kirtland Air Force Base in Albuquerque, New Mexico.
The existence of powerful EMPs have been known since the early days of nuclear weapons testing.
The US Army shielded all their signal lines, in some cases twice.
It was only then the enormously devastating effects of EMP were realized.
In the Soviet Union too, similar research on EMP was being conducted.
Hardening military hardware, primarily aircraft, became a major objective of the US Army.

Even nuts and bolts were made out of wood.
To provide better tensile strength, wooden boards were glued under heat and pressure to form massive elements.
To date it is the worlds largest structure composed entirely of wood and glue laminate.

While the Trestle is impressive to look, the most important component of ATLAS-1 was the generators.
The Trestle still stands in the arroyo, a few miles east of Albuquerque International Sunport.
Efforts are on to preserve it as a national monument.
