Furthering energetic materials research, development, testing, and evaluation in support of the Laboratory’s national security mission.

The Explosives Performance Research and Technologies (ExPRT) Group is composed of four unique sub-groups. We are a diverse team of more than 25 scientists and engineers that provide programs with expertise in the areas of both static and dynamic diagnostics, as well as standard and unique explosives test design, execution, analysis, and modeling across multiple length scales.

In addition to performance evaluations, our team designs, develops, and supports safety assessments of energetic materials in both normal and abnormal environments. ExPRT also contains the subject matter experts for initiation system aging and performance evaluations.
