This document provides a comprehensive analysis of the failure probabilities of U.S. solid rocket systems from 1964 to 2004. It outlines the historical failure rates, the percentage of catastrophic failures, and specific data on various solid propulsion systems. For example, between 1980-2004, the overall failure rate was 1.4%, with catastrophic failures occurring 37% of the time historically. The study also discusses future work to enhance propulsion designs and systems, referencing important works and studies in the field.
