Three approaches that can be taken to formulate safer explosives are 1 Use of low energy explosives 2 Use of fueloxidizer mixtures and 3 Use of soft, rubbery explosives. Munition vulnerability is strongly affected by the explosives properties, but it is also very dependent on the warhead physical characteristics. Other things that affect vulnerability include the quality of the explosive charge, ambient conditions, the presence of other ordnance items, and the way external energy is deposited into the explosive. An insensitive explosive must not react easily to external stimuli, or must react mildly under a variety of conditions. The difference in sensitivity must be large enough in practical situations to be worthwhile. Test results will be discussed that show that certain new, high-performance explosives also have exceptionally good vulnerability behavior.
