The Ikazuchi is a 300 meter long space aircraft carrier (spacecraft carrier?) used in more than one of the invasion fleets that attempted to recapture Earth from the Inbit. It is a class of ships, not the name of an individual ship. An Ikazuchi carries 140 Legioss in armo-soldier mode. The Ikazuchis that took part in the Third Invasion Fleet were painted red and dark gray.
