The analysis uses Air Force data to drive simulations of C-5 logistics operations and considers peacetime flying programs. This research was conducted in the Resource Management and System Acquisition program of Project AIR FORCE. It is one element of the Logistics Project, sponsored by Headquarters, United States Air Force (AF/LG). Headquarters, Air Mobility Command (AMC/LG), and Air Force Materiel Command (AFMC/XP) provided important assistance in ensuring the successful design and execution of this project. This report should be of interest to persons concerned with the logistics support of airlift aircraft and, particularly, to logisticians involved in the management of aircraft recoverable spare parts. Project Air Force Project AIR FORCE, a division of RAND, is the Air Force federally funded research and development center for studies and analyses. It provides the Air Force with independent analyses of policy alternatives affecting the development, employment, combat readiness, and support of current and future aerospace forces. Research is performed in three programs: Strategy and Doctrine, Force Modernization and Employment, and Resource Management and System Acquisition.
