Commodore Insignia

Rank Pennant
'Commodore' is a rank of the
Royal Navy above
Captain and below
Rear-Admiral. It is a
1 star rank and has a
NATO ranking code of OF-6. The rank is equivalent to
Brigadier in the
British Army and
Royal Marines and to
Air Commodore in the
Royal Air Force.
History
The appointment of Commodore dates to the mid-17th century: it was first used in the time of
William III. There was a need for officers to command
squadrons, but it was not deemed desirable to create new admirals (as
Post-Captains were promoted to Rear-Admiral in order of seniority). Captains assigned squadron command were given the title of Commodore, but it was not an actual rank. The officer so designated kept his place on the list of Captains. In 1748 it was established that Captains serving as Commodores were equal to
Brigadier-Generals in the Army.
Commodores could revert to the rank of Captain at the end of their posting (and Captains could be promoted directly to Rear-Admiral without ever having served as a Commodore).
The Royal Navy Commodore was eventually split into two classes. Those of the first class had a Captain under them to command their ship and were allocated one-eighth of all
prize money earned by ships under their command. Those of the second class commanded their own ship as well as the squadron. In 1783, Commodores of the first class were allowed to wear the uniform of a Rear-Admiral, a distinction which continued with some variation until the two classes of Commodore were consolidated in 1958.
By the 20th century, Commodores did not just command sea-going units (the naval
barracks in the three main naval bases of
Devonport,
Portsmouth and
Chatham were all commanded by Commodores, for instance) and the appointment of Commodore could also be held by specialist officers in certain positions as well as by line officers.
In 1996, Commodore was made a substantive rank in the Royal Navy.
Insignia
Commodores First Class, while wearing the sleeve stripes of a Rear-Admiral, had gold lace-covered
epaulettes with a crown, two stars and anchor (also worn by other Commodores but only with formal uniforms). They flew a swallow-tailed
pennant with the
St George's cross, but without the disc that appeared on the pennant of a Second Class Commodore.
Commodores Second Class wore a single 1.75 inch-wide row of lace below a ring (known in naval regulations as a curl) measuring 1.75 inches in diameter on both sleeve and shoulder-board. Their uniforms were otherwise the same as for Captains.
Modern Commodores wear the insignia previously worn by Commodores Second Class.
Equivalent naval ranks
Some
Commonwealth countries have replaced Commodore with an equivalent flag rank. The correct sleeve insignia for such a rank is a single 1.75 inch-wide row of gold lace below a gold lace curl with a diameter of 2 inches. The correct shoulder-board insignia comprises a crown (or national emblem for republics) with a crossed sword and baton on a gold lace-covered shoulder-board, however, there is some variation due to misconceptions about the status of stars in Commonwealth-style rank insignia. The rest of the uniform is identical to that of a Rear-Admiral.
