Commodore (rank)

The rank of commodore derives from the French commandeur, which was one of the highest ranks in the orders of knighthood, and in military orders the title of the knight in charge of a commande (a local part of the order's territorial possessions).

The Dutch Navy also used the rank of commandeur from the end of the 16th century for a variety of temporary positions, until it became a conventional permanent rank in 1955. The Royal Netherlands Air Force has adopted the English spelling of commodore for an equivalent rank.

In the Royal Navy, the position was introduced in the 17th Century to combat the cost of appointing more admirals—a costly business with a fleet as large as the Royal Navy's at that time.

The rank of commodore was at first a position created as a temporary title to be bestowed upon captains who commanded squadrons of more than one vessel. In many navies, the rank of commodore was merely viewed as a senior captain position, whereas other naval services bestowed upon the rank of commodore the prestige of flag officer status.

Commodore, in Spanish comodoro, is a rank in the Argentine Air Force. This rank is the equivalent of a colonel in the Argentine Army, and a colonel or group captain in other air forces of the world. The Argentine rank below commodore is the rank of vice-commodore (Spanish vicecomodoro) equivalent to a lieutenant-colonel in the Argentine Army, and a lieutenant-colonel or wing commander in other air forces.

Commodore is a rank in the Royal Netherlands Air Force. It is a one-star rank and has essentially the same rank insignia as the British air commodore.

Many air forces use the rank of air commodore. This rank was first used by the Royal Air Force and is now used in many countries such as Australia, Bangladesh, Greece, India, New Zealand, Nigeria, Pakistan, Thailand and Zimbabwe. It is the equivalent rank to the navy rank of "commodore", and the army ranks of brigadier and brigadier general.

The German air force used the concept of a unit commodore for the commander of a wing, usually in the rank of colonel (OF-5).

Commodore is also a title held by many captains as recognition of exceptional navigation ability and seagoing seniority in the Merchant Service, and by the directors of a few yacht clubs and boating associations. Commodores 'in command' as Master aboard Merchant Marine ships wear distinctive rank and cap insignia denoting their honorific high rank position.

During wartime, a shipping convoy will have a ranking officer—sometimes an active-duty naval officer, at other times a civilian master or retired naval officer—designated as the convoy commodore. This title is not related to the individual's military rank (if any), but instead is the title of the senior individual responsible for the overall operation of the merchant ships and naval auxiliary ships that make up the convoy. The convoy commodore does not command the convoy' escort forces (if any), which are commanded by a naval officer who serves as escort commander.

The U.S. Coast Guard Auxiliary also employs variants of the title of commodore. Members of the Auxiliary serve in the Coast Guard's uniformed auxiliary service and they do not have military rank, but who do wear modified U.S. Coast Guard uniforms and U.S. military-style officer rank insignia to indicate office. Auxiliary members who have been elected or appointed to positions in the highest levels of the organization, similar in nature to active and reserve rear admirals and vice admirals use the term commodore (e.g., District Commodore, Assistant National Commodore, Deputy National Commodore, National Commodore, etc.). These Coast Guard Auxiliarists may permanently append the title commodore, sometimes abbreviated COMO, to their names (e.g., Commodore James A. Smith, National Commodore; or COMO Jim Smith, (NACO)).[6]

In the Philippine Coast Guard Auxiliary—PCGA—each of the directors in command of the ten Coast Guard Auxiliary districts are commodores, as well as most of the Deputy National Directors (some may be rear admirals). Commodore is abbreviated to COMMO in the PCGA.

Vanderbilt University's intercollegiate athletics teams are nicknamed the "Commodores", a reference to Cornelius Vanderbilt's self-appointed title (he was the master of a large shipping fleet).

In the U.S. Sea Scouting program (which is part of the Boy Scouts of America), all National, Regional, Area, and Council committee chairs are titled as commodore, while senior committee members are addressed as vice commodore. Ship committee chairs do not hold this recognition.
