ATLAS-I (Air Force Weapons Lab
Transmission-Line Aircraft Simulator), better known as Trestle, was a
unique electromagnetic pulse (EMP) generation and testing apparatus built
between 1972 and 1980 during the Cold War at Sandia National Laboratories
near Kirtland Air Force Base in Albuquerque, New Mexico.
ATLAS-I was the largest NNEMP (non-nuclear
electromagnetic pulse) generator in the world, designed to test the
radiation hardening of strategic aircraft systems against EMP pulses from
nuclear warfare.
Built at a cost of $60 million, it was composed of two parts: a
pair of powerful Marx generators capable of simulating the electromagnetic
pulse effects of a high-altitude nuclear explosion (HANE) of the type
expected during a nuclear war, and a giant wooden trestle built in a
bowl-shaped arroyo, designed to elevate the test aircraft above ground
interference and orient it below the pulse in a similar manner to what would
be seen in mid-air.
Trestle is the world's largest structure composed
entirely of wood and glue laminate.
