Which rank is associated with O-9 in the U.S. Coast Guard?

The rank associated with O-9 in the U.S. Coast Guard is Vice Admiral. This rank is designated as a three-star officer position and is part of the flag officer ranks, which also include Rear Admiral (Upper and Lower Half) and Admiral. Being an O-9 indicates this high level of command and responsibility, typically involving significant leadership roles and operational command of large units or regions within the Coast Guard.

In the context of U.S. military rank structures, O-9 is consistently recognized as Vice Admiral across various branches, not just the Coast Guard. This alignment with other military services reinforces the rank's status and responsibilities, which include managing expansive operational responsibilities and serving at high levels of strategic planning.

Captain, which is an O-6 rank within the Coast Guard, is a significant position but does not hold the same seniority as an O-9. Similarly, both Rear Admiral Upper Half (O-8) and Admiral (O-10) represent different levels in the promotion hierarchy, firmly establishing Vice Admiral as the correct association with O-9 in this military context.
