To correct this inequity, the rank of commodore as a single star flag officer was reinstated by both services in the early 1980s. This immediately caused confusion with those senior U.S. Navy captains commanding destroyer squadrons, submarine squadrons, functional air wings and air groups, and so on, who held the temporary "title" of commodore while in their major command billet. As a result of this confusion, the services soon renamed the new one-star rank as commodore admiral (CADM) within the first six months following the rank's reintroduction. However, this was considered an awkward title and the one-star flag rank was renamed a few months later to its current title of rear admiral (lower half), later abbreviated by the U.S. Navy and U.S. Coast Guard as RDML.
