Which ranks are classified under the SECNAV and above category?

The SECNAV and above category encompasses the highest ranks within the Navy hierarchy, specifically focusing on those who hold significant leadership and organizational responsibilities. Flag officers, who are classified as O-7 to O-10, fit this category perfectly as they include Rear Admirals, Vice Admirals, and Admirals. These ranks carry critical command responsibilities and are integral to the strategic decision-making processes within the Navy.

In contrast, the other ranks listed do not fit into the SECNAV and above classification. Captain (O-6), Commander (O-5), and Lieutenant Commander (LCDR) all represent senior officers, but they do not possess the elevated authority and responsibilities that come with flag officer status. Therefore, while these ranks are important within their own right, they are not classified under the SECNAV and above category.
