Commodore (United States)

Commodore was an early title and later a rank in the United States Navy, United States Coast Guard and the Confederate States Navy. For over two centuries, the designation has been given varying levels of authority and formality. Today, it is no longer a rank, but it continues to be used as an honorary title within the U.S. Navy and the U.S. Coast Guard for those senior captains (pay grade O-6) in command of operational organizations composed of multiple independent subordinate naval units (e.g., multiple independent ships or aviation squadrons).

Use of the term "commodore" dates from 1775 in the then–Continental Navy, the predecessor of the modern U.S. Navy, when it was established (but not used) as a courtesy title reserved for captains in command of a fleet or squadron.

The first U.S. naval officer to become a commodore was John Barry, a senior officer of the Navy, appointed in 1794 after the former Continental Navy was reorganized into what would become the current U.S. Navy.

Because the U.S. Congress was originally unwilling to authorize more than four officer ranks in the navy (captain, master commandant, lieutenant, and midshipman) until 1862, considerable importance was attached to the title of commodore. Captain Isaac Hull, chafing at not being able to progress further in rank, wrote in 1814 that, if no admirals were to be authorized, something should be done to prevent, "...every midshipman that has command of a gunboat on a separate station taking upon himself the name of Commodore".

Like its Royal Navy counterpart at the time, the U.S. Navy commodore was not a higher rank, but a temporary assignment for navy officers, as Herman Melville wrote in his 1850 novel, White-Jacket.
