Ops Acquisition System

The Operations and Support (O&S) Phase is where a system is used and supported by users in the field.  The main focus on this phase is the execution of a support system that sustains the system in the most cost-effective manner possible.  The second main focus of this phase is the disposal of a system when it has reached its useful life. See Disposal.

A major focus during the sustainment effort of the Operations and Support (O&S) Phase is identifying root causes and resolutions for safety and critical readiness degrading issues. These efforts include participating in Trade Studies and decision making relative to changes to the product support package, process improvements, modifications, upgrades, and future increments of the system.  All these changes need to consider the operational needs and the remaining expected service life, Interoperability or technology improvements, parts or manufacturing obsolescence, aging aircraft (or system) issues, premature failures, changes in fuel or lubricants, and Joint or service commonality.
