What title is given to a commissioned officer in paygrade O-7 or above?

The title "Flag Officer" is designated for commissioned officers at the paygrade of O-7 or above. This classification encompasses a range of officers, including Rear Admirals, Vice Admirals, and Admirals, who are responsible for significant leadership roles and command positions within the Navy. A Flag Officer typically leads groupings of ships or units and holds considerable authority and responsibility in strategic planning and execution.

The term is derived from the historical practice where such officers would display flags that indicated their command at sea. The distinction of being a Flag Officer denotes a level of seniority and leadership that is critical in naval operations, where experience and strategic oversight play vital roles in mission effectiveness and operational success. Other ranks, like Captain and Commander, refer to lower paygrades and specific responsibilities within the naval hierarchy, while Admiral is a specific title that falls under the broader category of Flag Officers but is not all-encompassing at the O-7 level.
