What does the acronym CNO stand for in the Navy?

CNO stands for Chief of Naval Operations, which is the highest-ranking officer in the United States Navy. The Chief of Naval Operations is responsible for the command, control, and operation of the Navy, advising the President and the Secretary of the Navy on naval matters, and overseeing the training and readiness of naval forces. This position plays a crucial role in shaping naval policy and ensuring that the Navy is prepared to meet national defense objectives.

The other options listed do not accurately reflect the established titles or positions in the Navy. While "Commanding Naval Officer" might suggest a leadership role, it lacks the specific recognition and authority associated with the CNO position. Similarly, "Coastal Navigation Officer" and "Chief Naval Overseer" do not align with official Navy terminology or hierarchy.
