Commodore (United States)

For other uses of this rank, see Commodore (rank).

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.[1]

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.[1]

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.[1]

An American commodore in the early period, like an English commodore or a French chef d'escadre, was an officer (generally, but not exclusively, a captain) assigned temporary command of more than one ship. He continued his permanent or regular rank during the assignment. Once employed as a commodore, however, many jealously held onto the impressive title after their qualifying assignment ended. The Navy Department tried to discourage such continuing usage because it led to confusion and unnecessary rivalries.

Eventually the title of commodore was defined more strictly, and was reserved for captains so designated by the Navy Department, although the practice of retaining the title for life added some confusion. In 1857, Congress established the grade of flag officer. This generic title was intended "to promote the efficiency of the Navy", but differed little from the previous practice. Like the courtesy-title commodores, "flag officers" reverted to captain once their squadron command assignment was completed.[2]

American Civil War

Because of the acute need for officers at the beginning of the American Civil War, naval tradition was ignored and commodore became for the first time a permanent commissioned rank in the U.S. Navy. Eighteen commodores were authorized on July 16, 1862. The rank title also lost its "line command" status when, in 1863, the chiefs of the Bureaus of Medicine and Surgery, Provisions and Clothing, Steam Engineering, and Construction and Repair were all given the rank of commodore.

Flag officer

The rank of commodore continued in the Navy until March 3, 1899, when the Naval Personnel Act disestablished the title and made all commodores into rear admirals.[3]

According to Laws Relating to the Navy, 1919, the step was taken, "…on account of international relationships, the consideration of which caused the Navy Department to regard the complications confronting it as inimical to the honor and dignity of this nation, because of the adverse effect upon its high ranking representatives in their association with foreign officers". In short, U.S. Navy commodores were not being treated as flag officers by other navies, or given the respect that the Navy Department thought was their due.

As it would have been expensive to increase the pay of all the former commodores to the level of rear admirals, the U.S. Congress at the time specified that the lower half of the rear admiral list have pay equal to brigadier generals of the U.S. Army. If there were an odd number of rear admirals, the lower half of the list was to be the larger. All rear admirals lower half and full rear admirals, were considered equal to major generals, flew a blue flag with the requisite number of stars instead of a broad pennant, and were entitled to a 13-gun salute. The U.S. Supreme Court later held that the rank of commodore had been removed from the U.S. Navy, leaving it without a rank equivalent to brigadier general. This act disgruntled all the brigadier generals, who could now be outranked by officers who were their juniors in terms of service. This was a point of inter-service controversy for many years, especially after 1916, when the U.S. Army made its brigadier generals equivalent to rear admirals (lower half). Thus the two-star rank of rear admiral was now equal to that of major general.[4][5]

World War II and the Cold War

During the huge expansion of the U.S. Navy during World War II, the Department of the Navy was concerned that the appointment of more flag officers would create a glut of admirals whenever peacetime was achieved. However, some Navy and Coast Guard captains, although not yet selected for rear admiral (lower half), were holding commands of significantly higher responsibility than they had earlier and this needed to be recognized. The COMINCH of the U.S. Navy and Chief of Naval Operations, Admiral (later Fleet Admiral) Ernest J. King, proposed bringing back the older rank of "commodore" for these officers. President Franklin D. Roosevelt agreed, making the suggestion that the title be revived.[6]

As a result, the one-star officer rank for the U.S. Navy and the U.S. Coast Guard was re-established in April 1943 with the title of "commodore." In actual practice, some officers on admiral's staffs were also promoted to the rank of commodore. By the end of the War in the Pacific in August 1945, there were over 100 commodores in the U.S. Navy and U.S. Coast Guard. With respect to the U.S. Coast Guard, it should be understood that during World War II, the much-expanded Coast Guard was transferred from the Department of the Treasury to the Department of the Navy and was involved in combat operations in both anti-submarine warfare and amphibious warfare, thousands of miles away from home, and not just in its usual role of defending the coasts of the United States, detaining smugglers, lifesaving, and search and rescue operations.

After World War II, and with the rapid drawdown in size of both the Navy and the Coast Guard, very few of the wartime commodores were ever promoted to rear admiral. All promotions to commodore ceased in 1947, and nearly all of the commodores who had held the one-star rank had either been promoted to rear admiral or had retired from the Navy by 1950. However, as the Cold War evolved, the Navy began to rebound from its immediate post-World War II reductions. This expanding Navy saw growth in several mission areas, and the reintroduction and designation of senior captains in command of units comprising multiple ships (e.g., "flotillas"), multiple aviation squadrons or other similar organizations became increasingly commonplace, leading to increased use of the title of commodore for those senior captains occupying these highly responsible positions.

1982 commodore admiral / 1983 rear admiral (lower half)

In the late 1970s and early 1980s, following years of objections and complaints by the U.S. Army, U.S. Air Force, and U.S. Marine Corps, efforts were begun to reinstate commodore as an official rank in the U.S. Navy and U.S. Coast Guard with a pay grade of O-7, replacing "rear admiral (lower half)", which were Navy and Coast Guard flag officers who were paid at the one-star rank of an O-7 and carried the relative seniority of a one-star officer, but who, due to the elimination of the rank of commodore at the end of World War II, worn the same two-star rank insignia as a full, or "upper half," rear admiral, an O-8.

In 1982, the rank of commodore was finally and officially reintroduced in the U.S. Navy and the U.S. Coast Guard as the O-7 rank. This was intended to quell the long-running dissatisfaction by U.S. Army, U.S. Marine Corps, and U.S. Air Force officers with the U.S. Navy's and the U.S. Coast Guard's policy of honoring its rear admirals (lower half), who received the pay grade of O-7 while wearing the rank insignia of a two-star admiral, i.e., an O-8. The one-star officer's rank and insignia for Navy and Coast Guard officers was thence re-established with the initial title of commodore admiral.[7][8]

In 1983, following numerous objections by USN officers to the Chief of Naval Operations and USCG officers to the Commandant of the Coast Guard that this new title was unwieldy and confusing, the rank of "commodore admiral" was simplified to "commodore".

However, this action still failed to stem the confusion and the objections of senior officers in the naval services. This was because the U.S. Navy had long assigned the title (although not the rank) of commodore to selected captains holding major operational sea-going commands. Since at least the late 1940s, commodore had been used a "position title" for senior navy captains who commanded air groups and air wings (other than those officers commanding carrier air groups/carrier air wings, who were historically known and referred to as "CAGs"), destroyer squadrons, submarine squadrons, amphibious squadrons, patrol boat flotillas, patrol hydrofoil missile ship squadrons, special warfare groups, construction regiments, and other large seagoing commands. The U.S. Coast Guard had never previously used the title.

Later in 1983, the one-star U.S. Navy and U.S. Coast Guard admiral rank was changed back to its original O-7 pay grade title of "rear admiral" with the discriminator in seniority and protocol purposes of Rear Admiral, lower half, and a rank title abbreviation of RDML versus the O-8 rank title abbreviation of RADM.

From then on, commodore has remained a title for U.S. Navy captains in command of more than a single unit (other than captains commanding carrier air wings, who retained their traditional title of "CAG") and all U.S. Navy and U.S. Coast Guard one-star admirals were subsequently referred to as rear admiral. The U.S. Navy and U.S. Coast Guard rear admirals (lower half), continued to wear the single star for collar insignia and applicable shoulder insignia (i.e., flight suits, jackets, etc.), a single silver star on top of solid gold background shoulder board insignia, and a single broad gold sleeve stripe insignia for dress blue uniforms (service dress blue, full dress blue and dinner dress blue) of all USN and USCG flag officers in pay grade O-7, and for the service dress white and full dress white uniforms of female USN flag officers in pay grade O-7.[9]

The term "commodore" again reverted to that of an honorary title versus an actual rank for the limited number of captains in command of multiple units.

Present-day title usage


U.S. Navy

The U.S. Navy no longer maintains a rank of commodore, but the term has survived as an honorary title. Modern-day commodores are senior captains in the U.S. Navy holding major operational command of functional or "type" air wings or air groups (exclusive of carrier air wings) such as strike fighter wings, electronic attack wings, patrol and reconnaissance wings, airborne early warning wings, strategic communications wings, various helicopter wings, training air wings,[10] or tactical air control groups; destroyer squadrons; submarine squadrons; amphibious squadrons; mine countermeasures squadrons; riverine squadrons; coastal warfare groups and squadrons; special warfare (SEAL) groups; explosive ordnance disposal (EOD) groups; logistics task forces; and naval construction regiments.

With the exception of the naval construction regiments that are commanded by senior captains of the U.S. Navy's Civil Engineer Corps, all other commodores are senior captains who are warfare-qualified unrestricted line (URL) officers in that combat specialty (i.e., naval aviators and naval flight officers commanding "functional" or "type" air wings or air groups,[11][12] surface warfare officers commanding destroyer or littoral combat ship squadrons, submarine warfare officers commanding submarine squadrons, SEAL officers commanding special warfare groups, etc.).

The command pennant of the Commander, Submarine Squadron 16 (COMSUBRON 16) above the squadron's headquarters at Naval Submarine Base Kings Bay, Georgia.

Such officers employ the term "commander" in their organizational command title, this in keeping with the naval tradition of officers commanding a single ship, unit or installation being referred to as a "commanding officer" or "CO", while those captains and flag officers commanding multiple ships, multiple aviation squadrons, multiple air wings, task forces, fleets, etc., being known as a "commander" (but not to be confused with the USN / USCG rank of commander). With the exception of commanders of carrier air wings, captains in this latter category are referred to, both orally and in correspondence, as "commodore", but continue to wear the rank insignia of a captain.[13][14] Captains in command of carrier air wings continue to use the traditional title of "CAG" which dates from when these units were known as carrier air groups.

While technically not flag officers, captains holding a commodore billet are authorized a blue and white broad pennant,[15] also known as a "command pennant", which is normally flown from their headquarters facilities ashore and/or from ships on which they are embarked when they are the senior officer present afloat (SOPA). This swallow-tailed pennant has a white field bounded by two horizontal blue stripes, with the numerical designation or the initials of the command title in blue centered on the white field.[16]

U.S. Coast Guard

The U.S. Coast Guard presently designates the USCG captain commanding those U.S. Coast Guard cutters and other afloat and ashore USCG units comprising Patrol Forces Southwest Asia (PATFORSWA) as a "commodore." PATFORWA is headquartered at Naval Support Activity Bahrain in Manama, Bahrain and its primary area of responsibility is the Persian Gulf, as well as other areas coinciding with that of United States Naval Forces Central Command (NAVCENT). It is currently the only commodore billet in the U.S. Coast Guard and this usage mirrors the USN's use of the title "commodore".


U.S. Coast Guard Auxiliary

The U.S. Coast Guard Auxiliary also employs variants of the title of commodore. Members of the Auxiliary are civilian volunteers who 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 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)).[17]

U.S. Maritime Service

The United States Maritime Service uses the rank of commodore for their one-star flag officers, with the two-star rank being simply designated as "rear admiral." The rank is usually given to the president of one of the seven federal and state maritime academies who had not attained flag rank during his/her active duty naval career.

Civilian yacht clubs also tend to use the title "commodore" for their leaders, along with "vice commodore" and "rear commodore" in the same manner as "vice president," etc.[18]

The athletic teams of Vanderbilt University of the Southeastern Conference use 'Commodores' as their mascot, the nickname of the university's founder and namesake Cornelius Vanderbilt.
