GDI used the Firestorm Generator to power up the accompanying barrier for a limited time. The generator was used in some of GDI's most important strongholds, specifically their base in Hammerfest. During the Second Tiberium War though, Nod somehow managed to compromise the Firestorm defenses and overrun Hammerfest. A squad of Hover MLRSs escorting engineers was able to enter Hammerfest by water and recaptured the base by disabling the Firestorm Generator. The generator would later serve to be an important asset for GDI against Nod's chemical and cluster missiles late in the war.
