Nonlinear dynamic impact response analyses were performed on 115mm chemical rocket packing assemblies. Three different orientations of the packing assembly during impact with an unyielding surface were examined impacts of the packing assembly bottom, side and end. For impacts on unyielding surfaces due to drops from 40 feet, failures of one or more rocket agent canisters were probable if the packing was oriented so that the end or side struck the unyielding surface. It was concluded that bottom impacts from 40 feet would not cause leakage of rocket agent canisters. Calculations of the interaction effects between rocket packing assemblies inside a CAMPACT and the CAMPACT structure indicated the CAMPACT would have a significant ameliorating effect on packing response during end impacts from 40 feet.
