Command Centers
Build and defend your supply network.
To conquer the Cinderfleet and control Ironsound, you're going to need supplies: fuel, vehicles, Ironroots, ammunition, repair kits and more. A Factory Command Center will only manufacture supplies if it is connected to at least one island with a Resource Command Center on it. Defence Command Centers will deplete ammo and Whirlvane stores without a connection to a Factory Command Center island.
Resource Command Center
A Resource Command Center produces and ships raw resources to Factory Command Centers.

Produce resources to feed your fleet
Factory Command Centers require large amounts of raw resources to produce the supplies for your fleet. Build and defend Resource Command Centers to feed your supply network.

Turns raw material into the hardware, fuel and ammunition everything else runs on — while it stays connected.

Defence Command Center
A Defence Command Center will attempt to repulse any attacks and defend its island.

Defend your supply line
A Defence Command Center is equipped with sea-facing ground-to-ground missile launchers and ground-to-air missile launchers, plus a squadron of Whirlvanes. Whirlvane reinforcements rely on a supply network connection to a Factory Command Center and Resource Command Center. Defence Command Centers also provide spark-gap tether range repeater antennae and a landing pad for Stormvane aircraft.
