This report describes the effort to identify liquid and solid propulsion design parameters, development methodologies, and production operations techniques related to the improvement of propulsion reliability for future launch vehicles. Six key recommendations are made. There is a section on current practice and data base assessment. This is followed by a section on reliability enhancing methods. Finally, there is a section on quantification and prioritization of methodologies. Volume 1 contains Appendix A which includes an investigation of historical failure correlation factors using the SSME test and flight history as an example, a quick calculation of failure correlation factor versus engine out capability, a reliability analysis of current US launch vehicles, and a history of US launch launch vehicles. Volume 2 contains only Appendix B which is a compendium of trip reports accomplished during the performance of this study. Keywords Reliability, Launch vehicle, Propulsion development, Engine out, Failure correlation, Variability control, Reusability, Risk management, Reliability performance indicators PTO, Reliability growth analysis.
