What rank represents the O-9 pay grade?

The rank that represents the O-9 pay grade is Vice Admiral. In the United States Navy, the pay grade designations are linked to specific officer ranks. An officer at the O-9 level holds the title of Vice Admiral, which is a three-star rank. This position typically involves significant responsibilities, including commanding large naval forces or holding critical leadership roles within various naval operations.

Admiral, while also a high-ranking position, corresponds with the O-10 pay grade, which is the highest rank in the Navy. Therefore, it does not equate to O-9. The rank of Rear Admiral is classified as O-8, which is a two-star rank, and is lower than Vice Admiral. Brigadier General, on the other hand, is an Army rank that corresponds to O-7, making it unrelated to Navy ranks. Understanding these distinctions is essential for grasping military rank structures and their associated pay grades.
