摘要： A rocket system employing at least one rocket motor closure (22) that includes low and high load capability retainers (28, 42) that, respectively, provide an insensitive munitions system during storage and positive locking of a nozzle assembly (24) at launch, as well as an insensitive munitions (IM) approach that does not require use of such retainers by developing different normal and abnormal burn paths. The rocket motor also includes a pressure equalizing system that accommodates changing temperature conditions during storage as well as varying gas pressure inherent in gun-launched rocket systems in a manner that allows for thinner case cylinder design and increased propellant volume.
