Atgar SpaceDefense Corporation was the manufacturer of anti-vehicle weaponry and defense systems. Many of Atgar's products, such as the 1.4 FD P-Tower laser cannon, emphasized power over efficiency. Due to their low cost and obsoleteness, they were often found deployed by the Alliance to Restore the Republic during the Galactic Civil War,[1] but the weapons were generally low-powered and not as powerful as the weapons in use by the Galactic Empire.
Atgar was known to use the FD number system to categorize its military units. Despite being a space defense corporation, a certain number of Atgar's blaster cannons were fitted on GX12 Hovervans.
