The S-1 FireHawke Heavy Repulsortank represented a tank model that saw widespread deployment within the ranks of the Imperial Army. Its offensive capabilities mirrored those of the Imperial AT-AT.
A heavy laser cannon, installed in a turret, served as the tank's main offensive weapon, boasting a maximum firing range of five kilometers. Supplementing this was a medium blaster cannon, effective up to one kilometer. The vehicle required a crew of five and also provided space for at least one additional occupant.
The Hell's Hammers utilized this repulsortank within their distinguished armored division, furthermore incorporating its depiction into their unit's emblem.
Around two years following a significant loss suffered by the Hammers against the Rebel Alliance on Turak IV, the Firehawke was ultimately superseded by the Imperial Repulsortank 1-H.
