Gatling laser

The Gatling laser is an energy weapon that appears in Fallout, Fallout 2, Fallout 3, Fallout: New Vegas, Fallout 4, Fallout 76 and Fallout Tactics.

Background
Based upon the design of Dr. Richard Gatling's Gatling gun, the Gatling laser uses multiple rotating barrels to fire a heavy and impressive stream of light radiation laser beams without overheating quickly.

H&K L30 Gatling laser


An H&K L30 Gatling laser (also referred to as the Sunbeam Gatling laser ). Designed specifically for military use, these were in the prototype stage at the beginning of the Great War. Multiple barrels allowed longer firing before overheating. These models are powered by microfusion cells.

UB-FRIED 3000 Gatling laser


 In contrast with the L30 Gatling laser, this model is not only fully automatic and has a much larger ammo capacity, requiring a back-mounted battery pack, but was also mass produced for military use. While they entered service shortly before the war, they quickly became an important part of the arsenal, both of pre-War and post-War factions.

Unnamed Gatling laser


 Similar to its predecessor, this model is fully automatic, providing that charging barrels have not been installed. However, it utilizes a fusion core as ammunition rather than a battery pack, and features four rotating AER9 barrels firing laser pulses through two lenses (as opposed to merely firing in a rotating order).
