Project DarkStar: Controlling Material Deformation

Jonathan Belof | 21-SI-006

Executive Summary

The purpose of this project is to take the quantum leap from understanding to controlling dynamic material response. The scientific and technological achievements attained will enable a completely new paradigm for weapons physics and design and advance the U.S. national security posture.
