The Fac H-65 model, a heavy vehicle factory from Delvin Constructs, served as a crucial asset for the Alliance to Restore the Republic throughout the Galactic Civil War. The Rebel Alliance procured several of these factories, which were engineered to specialize in the manufacturing of vehicles with treads, from Delvin Constructs; subsequently, the Alliance coordinated with the manufacturers of the T4-B heavy tank and the MPTL-2a artillery to enable the production of these vehicles across a network of sites.
