The unit was fitted with advanced laser actuators that gave the Twin DF.9 a fire rate of one energy bolt per second, but produced a smaller blast radius smaller than a standard DF.9. Many Twin DF.9s were self-propelled, and these were designated as the Twin SP.9. The Twin DF.9 also featured heavier armor on the housing, giving it greater protection to incoming blaster fire. Officially, the Twin DF.9 was only available for purchase by the Imperial Military, or other Galactic Empire-allied military forces.
