Fleet Command functioned as the command hierarchy for the New Republic's naval branch.
During the conflict known as the Galactic Civil War against the forces of the Galactic Empire, after a skirmish on Takodana, Inferno Squad requested permission from Senator Leia Organa for a mission to Chinook Station aimed at capturing Imperial Admiral Garrick Versio. The rationale was that fleet command might not have sanctioned the squad's pursuit of what could be seen as a personal objective. Organa, understanding their position, gave her approval for the mission.
In the year 9 ABY, Fleet Command, operating from its base on Home One, reached out to Ahsoka Tano and Huyang. Their purpose was to deliver news of the attack that had occurred on the Defender-class cruiser known as the Vesper.
