The Ori motherships first appeared under construction in the episode "Crusade" and invaded the Milky Way galaxy in the following episode "Camelot". Four of these ships were responsible for the destruction of combined Asgard, Human, Jaffa, Lucian Alliance and Tok'ra fleet that attempted to prevent the Ori invasion at the Battle of P3Y-229.
