Energetics and munitions support national and global security, but they are also subject to regulations on hazardous chemicals commonly used in mission critical applications such as rockets, missiles, ammunition, and pyrotechnic devices. In these applications, energetic materials and munitions must perform as designed to ensure success in both training and combat operations. SERDP and ESTCP are investing in the development and demonstration of alternative materials and synthesis processes to reduce the environmental and occupational safety and health impacts of energetic materials and munitions while maintaining critical performance criteria.
