A Fleet Admiral was a rank in the Imperial Navy, directly above Admiral in the rank structure and immediately below High Admiral. A Fleet Admiral commanded an Imperial Fleet.
A Fleet Admiral reported directly to their Sector's High Admiral or Moff, and held authority over all subordinate Admirals and System forces under his command.
In certain cases, a Fleet Admiral may command an Imperial task force, an independent Imperial deployment assigned a specific objective for a short- or long-term campaign.
A Fleet Admiral was equivalent to a High General
in the Imperial Army
or a Force Marshal
in the Imperial Starfighter Corps
