Extreme but credible accidents and enemy action (EA)2 can cause munitions to react violently, with potentially severe consequences for people, equipment and infrastructure. Using a common scientific framework and set of evidence, Insensitive Munitions (IM) Policy drives the design of safer munitions; Hazard Classification (HC) controls their storage and transport; and Explosive Risk assessment builds on these to manage residual risks.

The aim of the Design for Vulnerability module is to explore the policies and processes used to manage the consequences of such EA2 events throughout the munition lifecycle; the science underpinning the response of energetic materials and weapons systems to these EA2 events; design principles to minimise the responses; and tools and techniques to manage these responses.

Taking the IM and HC criteria as a starting point, this module describes the reaction mechanisms that can lead to violent reactions and associated experimental and modelling techniques; and develops the qualities needed for safe design through explosive and propellant formulation; warhead, rocket motor packaging design; together with threat hazard assessment to develop a risk-based approach to accidents or actionEA2, through an holistic approach to munitions safety balancing a sense of the possible against need.

• Evaluate the relationships between IM, HC & ERA and the scientific principles and mechanisms controlling the response of munitions to EA²,
• Critique the state of the art and future direction of design solutions for EA²
