The most substantial privately held naval force in the galaxy, belonging to Baron Ragez D'Asta along with his family, was known as the D'Asta private fleet.
During 4 ABY, a number of bulk cruisers from this naval force were utilized by Admiral Llon Banjeer as mobile bases for TIE/LN starfighters during the Battle of the Hast Shipyards.
By the era of the Crimson Empire, this fleet had grown to be the largest private fleet in all of the galaxy.
In 11 ABY, Baron Ragez D'Asta deployed this fleet to defeat the Imperial Navy under the command of the self-declared Emperor Xandel Carivus.
