Who is the principal adviser to the secretary of the Navy?

The Chief of Naval Operations (CNO) serves as the principal adviser to the Secretary of the Navy on the conduct of the Navy and its operations. This position is critical for ensuring that the Secretary is informed about naval matters and strategic planning, providing insights into the readiness, capabilities, and overall mission of the Navy. The CNO's role includes not only advising but also implementing naval policy as directed by the Secretary, thereby playing a crucial role in the leadership and management of naval forces.

While other positions, such as the Chief of Naval Personnel and the Assistant Secretary of the Navy, have important advisory and operational roles within the Navy, the authority and primary responsibility to advise the Secretary on all naval matters ultimately lies with the Chief of Naval Operations. This distinction underscores the CNO's integral part in bridging military operations and executive decision-making within the Department of the Navy.
