A type of warship found in Warhammer 40K. An Attack Moon was the Imperial designation given to a class of massive Ork vessels that were encountered by the Imperium of Man during the War of the Beast from 544-546.M32. These massive voidcraft served as the flagships of the group of giant Ork warlords who were each known as The Beast.
An Attack Moon was capable of almost instantaneous travel through a hyperdimensional realm known as "subspace" created through the expenditure of the Greenskins' psychic WAAAGH! energy and was outfitted with a powerful gravitic weapon known as a "Gravity Whip" that was capable of ripping apart even the largest of battleships or even other planets.
