Who is ultimately responsible for maintenance on board Navy ships?

The Commanding Officer is ultimately responsible for maintenance on board Navy ships because they have the overall authority and accountability for the ship’s operations and personnel. This includes ensuring that all systems and equipment are operational and safe for both the crew and the mission. The Commanding Officer oversees the entire ship's organization, which incorporates various departments and their respective responsibilities, including maintenance.

While other positions, such as the Chief Engineer, play critical roles in overseeing technical maintenance and ensuring that engineering systems are operational, they report to the Commanding Officer. The Maintenance Manager focuses on the day-to-day upkeep and maintenance schedules but still operates under the authority and directives of the Commanding Officer. The Logistics Officer manages support and supply chains but does not directly oversee maintenance. Thus, the ultimate responsibility for maintenance falls to the Commanding Officer, as they are tasked with ensuring mission readiness and safety of the ship and its crew.
