Which titles typically rank under the Chief of Naval Operations?

The title that typically ranks under the Chief of Naval Operations is Commander. The Chief of Naval Operations (CNO) is the highest-ranking officer in the Navy and oversees the entire naval force. Commanders are a significant part of the Navy's organizational structure and often hold key leadership roles, operating at a level that directly supports the strategic objectives set by the CNO.

In the Navy's rank structure, Commanders fall in the pay grade of O-5, which is geared towards mid-level officers who are responsible for commanding ships, submarines, or aviation squadrons, as well as serving in significant staff positions. This rank is essential for ensuring the operational effectiveness of the fleet and the execution of policies derived from the top leadership, including the CNO.

Seaman Apprentice, while an entry-level rank, and Chief of Staff, typically a civilian or senior military role that supports the CNO, do not align as direct ranks under the CNO as Commanders do. Additionally, the title of Rear Admiral represents a higher rank above Commander and is also not considered to be directly under the CNO. Thus, Commander is the most fitting choice in the context of the Navy's hierarchical structure.
