"At Kuat Drive Yards, we're driven to excel. It is this uncompromising commitment to performance that has made us the largest military shipbuilding corporation in the universe."
A group of wealthy families, known as the Ten, joined together to create the largest shipbuilding concern in the galaxy, while terraforming Kuat to serve their needs.[4]
During the Old Sith Wars and New Sith Wars, Kuat's ship production facilities produced fleets of warships for the Republic.[3] In the centuries before the Clone Wars, they also constructed large ships for the protection of their sector[5] and collaborated with the Techno Union, of which their ship-production company was a member, in creating even larger designs.[6]
In 4 ABY, concurrent to the Battle of Endor, the Alliance occupied the shipyards. In an attempt to prevent either the Alliance or the Empire from taking over, Kuat of Kuat attempted to blow the yards up, although he was only partially successful, the full explosion being halted by Boba Fett.[13] The Empire soon regained control of the yards and the planet, and Bevel Lemelisk came thither to join the design team working on the Eclipse. A large Imperial fleet was soon garrisoned at the planet.[14]
Very soon after, Tyber Zannattacked the shipyards in order to steal the unfinished Eclipse and gained information about Imperial vaults from its computers. During this time, a rebel attack force led by General Han Solo invaded the sector chasing the retreating fleets from Endor. Zann was successful in taking the Eclipse, forcing out the Rebels, and decimating the Imperial fleet guarding Kuat Drive Yards, but decided that the Eclipse would be too big of a target and left with the vault's contents.[15]
In 7 ABY, it was the site of a three-way battle between WarlordZsinj, loyal Imperials, and the New Republic. At this time, Kuat's planetary defense forces were considered roughly equal to those of Coruscant. Kuat was at the time Imperial; Zsinj's forces hijacked the Razor's Kiss from the shipyards with the help of an Imperial who preferred it was in his hands than the New Republic's, but General Han Solo's fleet prevented Zsinj from taking it out of the system.[16]
In 8 ABY, Kuat was taken from the Empire by the New Republic: Bevel Lemelisk fled to join Durga Besadii Tai, while many senior KDY engineers fled to the Deep Core.[17] Kuat's powerful shipbuilding capabilities served the new galactic government well. Many of the first units designed under the New Class program were built at Kuat.
During the Yuuzhan Vong Invasion, Kuat hosted numerous meetings of the Defense Force High Command, and continued to supply warships to the New Republic Navy. Following the loss of Fondor, additional warships were dispatched to the planet to safeguard it and its extensive shipyards.
Later in the war, a large scale space battle took place over the planet. Hoping to catch the Alliance off guard, the Confederation launched an attack on Kuat to gain a foothold for the assault on Coruscant. Nek Bwua'tu set a trap for the Confederation with the First Fleet, Fourth Fleet, Seventh Fleet, Fifth Fleet, and the Hapan Home Fleet which proved successful until the Jedi (betraying Caedus for what he had become) left for Kashyyyk.
The battle dragged on for over a week with both sides sustaining heavy casualties every day. When the Bothans learned of the attack on Kashyyyk by Caedus, they broke out of the battle to go to its defense. The battle was essentially a draw.[20]
