Shipyard

The Shipyard is the place where you can use all your Stardust to make these repairs, here you can bring your exhausted fleets where you will receive the repair cost quote and once they are repaired they will be able to start exploring again, stronger than before.

For example, a 2000 Mining Power fleet at 0% needs 4312.5 Stardust to be fully repaired from 0 to 100.
