A Family fleet represented a specific kind of fleet utilized by the Chiss Ascendancy's various families. Certain limitations governed these family fleets; for instance, the 40 Great Families were prohibited from possessing larger warships, while the Nine Ruling Families were permitted to operate genuine warships. Nevertheless, constraints still existed concerning the overall size of the Ruling Families' fleets. Prominent instances of these fleets included the Xodlak fleet, the Pommrio fleet, Expeditionary Force Alpha, the Mitth family fleet, and the Clarr family fleet. A family held the ability to summon officers from the Ascendancy military to serve within their family fleets through the formal declaration of a Family emergency. This occurred circa 18 BBY, culminating in a battle involving Task Force Xodlak, the Pommrio fleet, and Expeditionary Force Alpha.
