"The Fac H-121 was a factory model, designed by Delvin Constructs, that was used by the Galactic Empire. While able to be tooled for the production of several vehicle types, the Empire most often produced the Self-Propelled Medium Artillery and 2-M Saber-class repulsor tank at these facilities. The Empire also attempted to use these facilities for constructing AT-AT walkers as well, but it was found the H-121 was too small and could not provide adequate attention for the advanced design."@en .
