AI had a stack of about 10 Space Yard Ships that it would move to the closest resupply base to its war zone. Using those ships it would rapidly build a large force of ships, bases and fighters, while providing a point where it could repair whole fleets in a turn. In about 10 turns it had built up enough defenses to hold the resupply base, and would move the Ship Yard Ships to the next resupply base, this made one hell of a snowball effect with the AI rapidly expanding because they could return damaged fleets to battle much faster, allowing them to complete the conquest of the system faster, which would give them more resources to build more ships etc... Worst game I ever had - lost 4 big fleets, and 3 systems just slowing them down enough to build a good defensive position.
