Megalith

A Megalith is an enormous mobile fortress, fully capable of space travel as well as planetary landings, that is used by the Necrons to initiate full-scale planetary assaults against hardened targets. Similar in appearance to the Monolith, but far larger, Megaliths are capable of ferrying multiple Monoliths within its hull, and then releasing them like a swarm upon the battlefield once a planetary assault has begun. Beyond their awe-inspiring size and the ability to transport multiple Monoliths, the Megalith is equipped with an arsenal of devastating Gauss and directed energy weapons. A Megalith was first encountered by the forces of the Imperium of Man in the hands of Nemesor Zahndrekh, a Necron Overlord of the Sautekh Dynasty, during the Necrons' Conquest of Uttu Prime in the Vidar Sector in the late 41st Millennium. At Uttu Prime, Zahndrekh's Megalith and its related forces were responsible for eradicating 3 regiments of the Imperial Guard's elite Catachan Jungle Fighters and 3 full companies of Imperial Fists Space Marines.
