Gameplay Notes

Fleet Oilers (AO) can notably refuel ships mid-sortie using Underway Replenishment.

• They can also carry Landing Craft, which is useful for Resource Farming.

Special Mechanics

Example of Underway Replenishment translated.

Underway Replenishments are consumable items that are used to restore fuel and ammo mid-sortie when consumed.

• As "consumables", they do not take any equipment slot and appear in the Inventory.
• Only Fleet Oilers (AO) and Kumano Maru can carry them, including in their RE.

When entering a boss node, a prompt will appear giving a choice to use the Underway Replenishment(s) or not.

• The cost of the resupply will be deducted from the stockpile.
• The resupply cannot be activated when having insufficient fuel or ammo.
• The amount of fuel and ammo resupplied depends on
  • The fleet type (single or combined)
  • How many Resupplies are carried.

The resupply rates are as follow:

Used	Single Fleet	Combined Fleet
1	25 %	15 %
2	36 %	27.5 %
3	47 %	40 %

This mechanic should only be used to avoid Fuel penalty or/and Ammo penalty.
