The USAF's R and M 2000 policy emphasizes the integration of reliability and maintainability considerations into a system's preliminary design phase. This emphasis leads to unique requirements for turbine engines, including those of 'wooden rounds' such as a HARPOON type missiles. In particular, it requires the development of tools for assessing the impact of design iterations on the reliability of 'wooden round' weapon systems. Such tools must account for design iterations impact on storage, captive carry and launch reliability. A Markov approach is described in this paper, which provides an ability to track the reliability of a fleet of missiles/engines on a period by period basis, allowing one to assess when scheduled maintenance is appropriate and what components require such maintenance. Thus, inputs for Life Cycle Costing are generated, as well as the ability to determine tradeoffs between R and M and performance.
