Solid Rocket Motors (SRMs) have been used for decades to propel tactical and ballistic missiles as well as space launchers. The high impulse delivered by today’s solid propellants and their availability mean that they continue to be widely used by the military.
An increasing number of warhead designs shows a less violent response than Detonation (type I) in cook off or impact scenarios. In order to quantify the safety benefits, MSIAC is working on improvements in the risk management of such munitions.

TNT equivalency is commonly used to quantify the explosive effects of energetic materials and munitions. For scientific purposes, it is a means to compare the explosive effects delivered by different energetic compositions.
One of the challenges related to munitions safety is to make munitions insensitive to external stimuli (heating, operational threats, etc.) To reduce the violence of response of munitions to Insensitive Munitions threats, several mitigation technologies are used.
Rocket motors are designed to propel payloads towards their final destination by ejecting hot gases through a nozzle. The gases are produced by the combustion of fuel and oxidizers which can be either separated (hybrid combustion) or embedded into each other (gun propellant, propellant grain).
