Recent efforts have aimed to replace the near-infrared (NIR) tracer composition (R-440) currently specified for some types of 7.62 × 51 mm NATO ammunition with a more environmentally sustainable composition (R-680). This report summarizes the two ma

Current fielded delay formulations face increased scrutiny due to their environmentally hazardous components (i.e., BaCrO4/KClO4), and there is an immediate need for viable replacements. In this work, the W/MnO2 composition is explored as an environm

We report here on the use of magnesium diboride (MgB2) as a barium-free alternative for the pyrotechnic generation of green light. Formulations employing KNO3 as the oxidizer, MgB2 as the fuel, and various binders and additives were investigated. Upo
