Abstract: The low vulnerability of solid rocket engine is an important performance in relations to munitions survivability Development of low vulnerabilty and insensitive munitions since 1985 is described,which includes analysis and comparison of methods of subscale laboratory tests The hazard assessment protocols,hot fragment ignition threat/response and low vulnerability design are discussed Finally,policy and way of further research and deveopment of low vulnerability solid rocket engine are proposed

Key words: Solid propellant rocket engine;Vulnerability;Propellant sensitivity;Safety test;Missle accident
