A clandestine construction effort by Rothana Heavy Engineering for the Kaminoan government's covert clone army intended for the Galactic Republic resulted in a fleet comprised of a dozen Acclamator-class assault ships. Upon the arrival of Jedi Master Yoda to assume leadership of the army, the fully constructed assault ships making up the fleet were promptly dispatched to Kamino to take on the clone trooper forces. Select clone units had been trained to pilot these vessels and executed their duties effectively.
Following the embarkation of the two Sector Armies, the fleet made its way to Geonosis to bolster the Jedi assault team, which was suffering heavy losses. In spite of their considerable size, the assault ships demonstrated impressive atmosphere maneuverability, catching the Separatist Alliance defenders off guard. The fleet then launched LAAT/i gunships to support the Jedi, while a number of the assault ships landed and began to disembark ground troops.
