Mandalmotors is our primary source of weapons and armor along with mandaltech.
MandalMotors at some point took over from the now defunct MandalTech.
It built various spaceships including the Pursuer-class enforcement ship, one of which was used as Boba Fett's Slave II. It was established several hundred years BBY by General Gustav Zenlav.
During the Clone Wars, the Mandalorian government, with its new army of Mandalorian Protectors, took control of the MandalMotors facilities so they could be used by the Confederacy of Independent Systems.
MandalMotors was not allowed to do business under the auspices of the Galactic Empire until an Imperial "advisor" was placed on the company's board of directors, although this did not stop the sale of weapons to Tyber Zann's organization. Following the Battle of Endor, this "advisor" was ousted in favor of support for the New Republic.
By the Second Galactic Civil War, it was headed by Jir Yomaget and had donated a communal building to the community of Keldabe. After the discovery of a new vein of Mandalorian iron, production began on a new beskar-reinforced design, the Bes'uliik-class assault starfighter.
