What authority oversees the transfer of Midshipmen to the Reserve component?

The authority that oversees the transfer of Midshipmen to the Reserve component is the Department of the Navy. This is because the Department of the Navy encompasses both the Naval and Marine Corps services and is responsible for providing guidance and policies on various personnel matters, including the transfer processes for Midshipmen transitioning into the Reserve component. Such transfers involve regulations and procedures that fall under the purview of the Department, ensuring that all actions align with broader naval policy and operational readiness requirements.

The other entities listed, while they have roles in military personnel management, do not specifically govern the transfer of Midshipmen to the Reserve component. The Naval Academy Board, for instance, focuses more on the administrative aspects of the Naval Academy and the education of Midshipmen rather than personnel transfer authority. The National Guard Bureau is primarily concerned with federal and state National Guard forces, and the Military Service Chiefs manage their respective services but do not oversee the direct transfer policies for Midshipmen on a broader scale. Thus, the Department of the Navy is the correct authority in this context.
