Commodore is a naval rank, the equivalent of which is used by the service organizations of many civilizations. As a traditional grade, commodore is the most junior flag officer rank of a naval organization, below admiral (usually under rear admiral) but senior to captain. Commodores command groups of ships, as opposed to captains commanding single ships or units. In comparison to other ranking systems, this rank is equivalent to the infantry brigadier general.

Many rank systems only use this rank during wartime. During times of peace an officer of this rank is referred to as a rear admiral, lower half.

The rank of commodore was used by Starfleet until at least the 2270s.

Use of the rank of commodore appears to have dwindled by the 24th century, as no such ranked persons were seen or referenced in TNG, DS9 or VOY.

Totlh was the Klingon term for the rank of commodore. (The Dominion War Sourcebook: The Fires of Armageddon)

Star Trek: IntrepidEdit

As of the late 24th century, the rank of commodore was still in use by some officers, albeit in a much more limited area than its counterpart, rear admiral. Aaron Prentice and Nathan Twining were examples of latter-day commodores. It was noted by Data that the number of commodores in Starfleet in the 2370s numbered in the low double digits. (Star Trek: Intrepid; Shatnerverse)

Other speciesEdit

Romulans referred to a commodore as a khre'riov (commander-general) and, like its Starfleet counterpart, were the lowest flag rank. (RIS Bouteina)

Lyrans had two grades of commodore, occupying the lowest two flag ranks, senior commodore being the highest. (RIS Bouteina: "The Measure of a Romulan")
