In 1899, the substantive rank of commodore was discontinued in the United States Navy, but revived during World War II in both the U.S. Navy and U.S. Coast Guard. It was discontinued as a rank in these services during the postwar period, but as an appointment, the title "commodore" was then used to identify senior U.S. Navy captains who commanded squadrons of more than one vessel or functional air wings or air groups that were not part of a carrier air wing or carrier air group. Concurrently, until the early 1980s, U.S. Navy and U.S. Coast Guard captains selected for promotion to the rank of rear admiral (lower half), would wear the same insignia as rear admiral (upper half), i.e., two silver stars for collar insignia or sleeve braid of one wide and one narrow gold stripe, even though they were actually only equivalent to one-star officers and paid at the one-star rate.
