Resupplying is mainly done through the Supply menu. It is important to keep girls fully supplied as low supplies will severely hamper their combat effectiveness, or even prevent them to do sorties.

The different methods for resupplying girls are detailed below.

Gifting using the Food Supply Ships Mamiya and Irako is not considered as "resupplying".

Overview

All ships are supplied with fuel and ammo , as well as bauxite for any ship with aircraft capacity .

Ships have consumption values depending on their class and remodel.

The main effects of low supplies are as followed:

Low fuel induce "Fuel penalty", which reduces evasion, starting at <75% fuel.
Low ammo induce "Ammo penalty", which reduces damage, starting at <50% ammo.
Low plane count (bauxite ) induce a reduction of both damage and air control power.

In addition:

A fleet will be unable to sortie if fuel or ammo is empty for a single ship.
- A run can be completed with ships reaching zero of any resource mid-run
Low supply levels will cause Expeditions to fail.
Bauxite is only consumed when there are depleted plane slots in the fleet.
For resupply costs, please refer to the individual ship girl pages. Keep in mind that costs can change for each remodel.

Resupplying

The cost of resupplying is simply:

[math]\displaystyle{ \text{Cost} = \lfloor \text{Consumption} \times \text{%Loss} \times \text{Mod}_\text{Married}\rfloor }[/math]

[math]\displaystyle{ \text{Consumption} }[/math] is the fuel or ammo consumption of the ship girl.
[math]\displaystyle{ \text{%Loss} }[/math] is the amount of fuel or ammo that needs to be resupplied, expressed as a percentage.
[math]\displaystyle{ \text{Mod}_\text{Married} }[/math] is the married Ship multiplier. It is [math]\displaystyle{ 0.85 }[/math] for married ships, otherwise [math]\displaystyle{ 1 }[/math]

Supply Menu

Supply menu screen and all its features

The resupply menu can at most resupply one fleet or a page of unused girls at a time.

Ship Girls

Resupply Fleet

To resupply the entire fleet, simply click one of the two "resupply all" buttons as described above. This will resupply the fuel, ammo, and lost planes of all the girls in the fleet.

In the case a ship is already at maximum fuel & ammo supply but is missing planes, this will not refuel its planes.

Individual Resupply

For more control over resupply, such as when completing quest E4, girls may be resupplied individually.

Click on the check box to the left of the ship banner to select her.
Choose whether to resupply fuel , ammo , or both (まとめて補給).
- "Both" also resupplies planes.

Planes

Planes slots are usually automatically replenished when a ship is resupplied. However, there are some cases where a ship has full supplies while her planes are depleted. To replenish only planes, click the Replenish Planes (艦載機補充) button.

Resupplying Planes costs [math]\displaystyle{ 5 \times \text{N}_\text{Planes Lost} }[/math] Bauxite.
The resupply is slot dependent, so equipping any plane in a depleted slot won't resupply it.
Jets' steel consumption is not counted as a "resupply".

Expedition Menu

After clearing Quests D25 and obtaining the Provisional Resupply, it is possible to resupply the expedition fleets immediately before sending them on expeditions from the expedition menu. Simply click on the small resupply button beside the "Dispatch" button.
