Iron Harvest Wiki

King Art Games announced the Operation Eagle DLC on April 29th of 2021. It is the second DLC to come out for Iron Harvest and launched on May 27, 2021.


The Operation Eagle is a stand alone expansion that adds in a brand new faction, Usonia, that is the 1920+ equivalent the the USA. It also provides each faction with at least 3 different types of aircraft. A common one is the lightest and most easy to produce in large numbers. Medium Aircraft are stronger equipped for combat but are no match for the Heavy Aircraft that can dominant the enemy. Air Factories and Anti-Air Defenses will be added to each faction's build roster as well.
