The “Barbarossa” Patch 1.11.4 now available for Hearts of Iron IV has a plethora of balancing changes and improvements. So, let’s dive right into the highlights!

Balancing Changes

First up, Naval bases now cost 5,000 Industry Capacity (IC) instead of 3,000. They also incur an extra cost of 1,000 for every additional level gained.

If you request for an air supply mission, be ready as the fuel costs have increased by 50%. Moreover, air supply now grants 0.2 supply per plane from 1.2, but you’re guaranteed 100% mission efficiency to compensate.

The Army and Navy Spirits have their cost discounted to 20/35/50. Additionally, the Air spirits now cost 50 air experience.

The developers also increased the hard attack (HA) and soft attack (SA) values of multiple tank guns. Furthermore, the costs for medium modules are reduced, and base speeds are increased slightly.


The Soviet Union AI now prioritizes building a decent civilian factory base before doing anything else. Aside from that, you can count on the USA to produce a usable infantry template from here on out.

If you are into modding, the documentation has been updated to reflect the changes implemented in this update.
