Galaxy-class lasers are a form of ship-based energy weapon designed and used by the Asgard in order for them to do battle with their enemies. Asgard bombers and Chariots were fitted with five galaxy-class lasers, which made them more than a match for most Goa'uld motherships. Asgard cruisers and Transports were fitted with a light variant of this weapon as well. (RPG: "First Steps: The Stargate Unexplored Worlds Roleplaying Sourcebook")
