Who has overall responsibility for ensuring ships maintenance is accomplished following the 3M procedures?

• A. CO
• B. XO
• C. 3M System Coordinator
• D. Divisional Officer

Answer: (A)

The main idea is who holds ultimate accountability for maintenance in a 3M program. In naval ships, the commanding officer has overall responsibility for ensuring maintenance is carried out according to 3M procedures. This means the CO sets the policy, ensures resources and support are available, and guarantees the 3M cycle—planning, scheduling, execution, and documentation—is followed so the ship remains ready.

The 3M System Coordinator handles the day-to-day operation of the 3M program, maintains records, and coordinates between departments to keep maintenance on track. The Executive Officer supports operations and can oversee execution, but the responsibility for the program’s adherence rests with the CO. Divisional Officers manage their own department’s tasks within the 3M framework, reporting up through the chain, yet ultimate accountability lies with the commanding officer.
