What kind of maintenance does the 3-M system primarily focus on?

The 3-M system primarily focuses on preventive and corrective maintenance because its primary goal is to ensure the operational readiness and longevity of Navy equipment and systems. Preventive maintenance involves routine checks and servicing of equipment to prevent failures before they occur, thereby enhancing reliability and safety. Corrective maintenance, on the other hand, is aimed at fixing issues that have already arisen to restore the equipment to a fully operational state. This dual approach minimizes downtime and extends the life cycle of equipment, aligning with the Navy's mission to maintain high standards of readiness.

While other maintenance types might play a role in overall maintenance strategies, the 3-M system is explicitly designed to support a structured approach that emphasizes being proactive (through preventive measures) and responsive (through corrective actions) to maintenance needs.
