Refuelling Capacity

Each level increases the deuterium refuelling capacity for allied fleets. Higher levels allow more ships to be refuelled per hour during ACS operations.

Tips

Alliance PvP

The Alliance Depot is mainly useful in large alliance wars where coordinating multi-system attacks requires mid-flight refuelling stops.

Solo Players

If you play mostly solo, this building is low priority. Invest those resources in mines or military.
