A boss from Ace Combat 7. The Arsenal Birds were automated airborne fortresses developed by Osea to assist in the defense of the International Space Elevator. After the outbreak of the Lighthouse War, both were hijacked by Erusea. The Arsenal Bird's armaments and defenses include missiles, lasers, and an energy shield, but the bulk of their offensive power is centered on the large numbers of drone fighters they carry, and can rapidly deploy into battle.
