The Fondor Shipyards above the planet Fondor were large, wheel-shaped installations that featured multiple hangars as well as several docking bays for Imperial-class Star Destroyers. Rebel agents were located near the Fondor Shipyards, and reported to General Airen Cracken about their findings.
After the fateful Battle of Endor, which saw the destruction of the second Death Star and the death of Emperor Sheev Palpatine, Inferno Squad was sent to one of the shipyards to protect climate disruption arrays for Operation: Cinder by Admiral Garrick Versio and one of the late Emperor's sentinel droids. Shortly after, one of the stations was attacked by Rebel Alliance vessels, in which they attempted to hijack the Star Destroyer Dauntless, which was carrying the climate disruption arrays. The attack failed, and Alliance forces were defeated.
Shortly before the Battle of Jakku, the Shipyards were the site of another battle, this time being attacked by the New Republic, the successor state to the Rebel Alliance. The battle resulted in a New Republic victory.
