The G-X1 Onslaught, alternatively named G-X1 Firehauler, represented a bomber design manufactured by Galactic Solutions Industries in the era of the Galactic War. Its design garnered considerable admiration from pilots serving in both the Galactic Republic and the reconstituted Sith Empire, with the latter faction acquiring a substantial quantity of G-X1 units to bolster their starfighter forces.
Introduced within the Digital Expansion Star Wars: The Old Republic: Galactic Starfighter as a Premium vessel exclusively obtainable through the Cartel Market, the G-X1 carries the designation "Firehauler" for Republic players and "Onslaught" for Imperial players. In terms of gameplay mechanics, it mirrors the functionality of the Warcarrier/B-4D Legion.
