Mod «MTG Expanded» for Hearts of Iron 4 (v1.10.1 - 1.10.8)

MTG Expanded

Man the Guns Extended adds two new submarine hulls and over 20 new ship modules greatly expanding ship customization options. This mod makes no changes to vanilla ships or modules. It only adds to them so the AI experience should remain unchanged. The new ships and modules can all be unlocked through research in the naval technology tree.
