Before the base's destruction, a downed Imperial II-class Star Destroyer attempted to send TIE bomber reinforcements to back up the troops at the base, but their efforts were stopped by Iden Versio and Shriv Suurgav who destroyed the remains of the ship.
During the battle, All Terrain Armored Transports of the Hellhound attack force were deployed from the Star Destroyer Interrogator in a last ditched defense of the base. Before retreating into the Unknown Regions, the remaining Imperial forces destroyed the facility. The Empire's final goal during the battle was to prevent the New Republic fleet from reaching the base. The base was operated by the Galactic Empire before and during the Battle of Jakku. The Imperial research base was a facility located in Carbon Ridge on the planet Jakku.
