The Conference Proceedings contains the 23 papers and the Technical Evaluation Report presented at the Propulsion and Energetics Panel 78th A specialists' Meeting on 'Insensitive Munitions', which was held from 21st-23rd October 1991 in Bonn, Germany. The Specialists' Meeting was composed of the following sessions: Insensitive Munitions Policy (4); Explosives and Gun Propulsion (6); Rocket Propulsion (4) and Physical Phenomena Associated with Insensitive Munitions (9). The papers presented reflect the big progress made in understanding and characterizing the response of energetic materials to external stimuli such as shock, fire and bullet impact. Small scale testing results, statistical data and approaches to numerical modelling are reported. The need for deeper investigation of the mechanisms involved, for corroboration of the statistical results and for better fidelity criteria of small scale testing becomes apparent. The NATO Insensitive Munitions Information Center (NIMIC) recently established in Brussels is charged to provide more exchange of information and international cooperation.
