Docking

Bucket icon

• Docking (repair) will restore your ships to full health, at the expense of fuel and steel.
• While under repairs, it is not possible to cancel repairs or modify equipments or perform other activities like modernization.
• Larger and higher-level ships take more time to repair. But it is possible to repair a ship instantly by using fast repair material (bucket).
• Buckets DO NOT offset the resource requirements (fuel & steel) needed for repairs. The needed resources will still be consumed regardless.
• If a ship ends repair with 39 morale or less, it will be reset to 40 upon finishing.
• You can shave off the last minute of repair time by switching to the docking screen when a ship has less than one minute of repair time to go.
• You start the game with two repair dock slots—you can pay money (DMM points) to buy keys in the shop and expand to 3 or 4 slots.
• To use buckets to instantly finish repairs use the green button (shown below) or activate the slider on the repair confirmation window (shown on the side).

Repair time

Confirmation window for repairs

[math]\displaystyle{ \text {Total repair time} = \text {HP loss} \times \text {base repair time} \times \text {ship type} + \text {30 seconds} }[/math]

Ship Type	Multiplier
Battleship, Aviation Battleship, Aircraft carrier, Repair ship	2
Heavy Cruiser, Aviation Cruiser, Fast battleship, Light aircraft carrier, Submarine tender	1.5
Light Cruiser, Destroyer, Submarine Aircraft Carrier, Seaplane tender, Amphibious assault ship, Torpedo Cruiser	1
Submarine	0.5

• Fast battleship: Kongou-class, Bismarck
• Submarine Aircraft Carrier: I-58 Kai, I-19 Kai, I-8 Kai, and I-401.
• Amphibious assault ship: Akitsumaru
• Repair ship: Akashi
• Submarine tender: Taigei
• These are assumed times based on calculations and rounding.
• Represented as [minutes]:[seconds]

Repair cost

See ship list or remodeled ship list for their base fuel cost.

[math]\displaystyle{ \text {Steel} = \text {Base fuel cost} \times \text {HP loss} \times 0.06 }[/math]
[math]\displaystyle{ \text {Fuel} = \text {Base fuel cost} \times \text {HP loss} \times 0.032 }[/math]

Examples

Level 67 Kongou with 41/75 HP (34 damage) will have:

• Repair time:
  • [math]\displaystyle{ 34 \times \text{455 seconds} \times 1.5 + \text{30 seconds} = \text{23235 seconds or 6:27:15} }[/math]
• Resource costs:
  • [math]\displaystyle{ 90 \times 34 \times 0.06 = \text{183 steel} }[/math]
  • [math]\displaystyle{ 90 \times 34 \times 0.032 = \text{97 fuel} }[/math]

Level 150 Musashi with 1/106 HP (105 damage) will have

• Repair time:
  • [math]\displaystyle{ 105 \times \text{915 seconds} \times 2.0 + \text{30 seconds} = \text{192180 seconds or 53:23:00} }[/math]
• Resource costs:
  • [math]\displaystyle{ 250 \times 105 \times 0.06 = \text{1575 steel} }[/math]
  • [math]\displaystyle{ 250 \times 105 \times 0.032 = \text{840 fuel} }[/math]
• This is the highest in the game currently.
