What rank is assigned to the O-10 pay grade in the Navy?

The rank assigned to the O-10 pay grade in the Navy is Admiral. This is the highest rank within the officer ranks and is typically held by individuals who serve in top leadership positions, often overseeing large naval operations, fleets, or the entire Navy as part of a unified command. Admirals are responsible for strategic decision-making at high levels and command significant resources and personnel.

In contrast, other ranks like Rear Admiral Lower Half, Lieutenant Junior Grade, and Commander represent lower pay grades and corresponding responsibilities. Each of these ranks serves important roles within the Navy but does not reach the capacity or authority of an Admiral, which is why Admiral is accurately recognized as the O-10 rank.
