scope:

This instruction applies to total inventory management of Navy and Marine Corps whole engines and modules. Total inventory should be interpreted to mean all engines and modules, whether installed or uninstalled. Additionally, those engines and modules supported via performance based logistics, contractor logistics support, or any other like-type of agreement are included in the interpretation of total inventory and, therefore, held accountable under the concepts of this instruction.

Purpose. To establish policy, roles, and responsibilities for developing, validating, and updating whole engine and engine module requirements as the National Military Strategy (NMS) changes and as improved management processes become available.
