Linear Explosively Formed Penetrator
A Linear Explosively Formed Penetrator (LEFP),
a counterpart to a linear shaped charge, is
capable of projecting a massive wide metal “blade”
instead of a narrow jet or compact slug.
DET developed and built such a device for rapidly cutting through metal hedgehog obstacles, as might be encountered on a beach protected from amphibious assault. The charge we designed and tested completely
severed a 6″ wide steel I-beam.
Below are flash radiographs showing the shape of the projected and formed copper liner. Copper is used for its high ductility and mass density.
