When a colony has stayed operational for at least six months or more, the development of the Ironwing Maw makes it apparent. Though similar to the Blitzwing in its use, the increased armor and higher level of Bioguns as well as increased gas capacity for floating, the Ironwing takes the roll of the Araculis premier attack air unit. And its larger size allows it to better match magitek fighters in combat.
