What is the rank for the Navy O-9 pay grade?

The rank corresponding to the Navy O-9 pay grade is Vice Admiral. This rank is typically held by officers serving in high-level positions overseeing significant aspects of naval operations, including command of multiple ships, fleets, or major operational commands.

A Vice Admiral's responsibilities may include serving as a senior advisor in various strategic areas, where they play crucial roles in shaping naval policy and executing missions. In the organizational hierarchy, this rank is positioned above Rear Admiral (which is an O-8 pay grade) and below Admiral (an O-10 pay grade), which highlights its significance in the Navy’s command structure.

Other ranks mentioned, such as Admiral (O-10) and Fleet Admiral (a five-star rank that is not typically used in peacetime), do not represent the O-9 pay grade, affirming that Vice Admiral is the correct answer related to this specific rank classification.
