Turbine failure must be reported to whom?

The requirement to report turbine failure to NAVSEA (Naval Sea Systems Command) stems from the critical role that this organization plays in overseeing the lifecycle of naval ships, including their propulsion systems. NAVSEA is responsible for the research, development, and support of the Navy's ships and submarines. Reporting turbine failures to them is essential because they need to assess the situation, understand the root cause, and implement solutions to prevent future occurrences. This process ensures that the Navy maintains operational readiness and the safety of its equipment and personnel.

Other options do not reflect the proper reporting chain for these incidents. For instance, while the U.S. Naval Command oversees naval operations, they typically rely on specialized commands like NAVSEA for technical issues related to equipment failures. The Department of Defense has a wider scope of responsibilities that generally do not involve direct oversight of individual machinery failures on naval vessels. Lastly, reporting to the engine manufacturer is relevant in some maintenance contexts, but for official reporting of failures, NAVSEA is the correct authority that can initiate investigations and necessary actions.
