戦闘航海中の海上で燃料弾薬を補給することが可能です。 これを保持した状態で燃料が欠乏すると戦闘航海中に「洋上補給」が発動し、燃料弾薬が洋上で「補給」されます。 長期戦となる艦隊決戦のサポートにご活用ください。 (発動すると消滅します。)

It's possible to perform resupply on the seas to ships performing combat sailing.
When fuel is low while this is being held, "Maritime Resupply" will happen, and fuel & ammo will be replenished on the seas.
Please use this well as a support for the final battle, which could become a war of attrition.
(Will disappear when activated.)


  • When entering a boss node, a prompt will appear giving a choice to activate the Maritime Resupply, restoring 25% of maximum ammo and fuel to each ship in single fleets.
  • It can also restore 15% in combined fleets, which applies to both fleets in a Combined Fleet situation.
  • The fuel and ammo cost will be deducted from the player's stockpile. If insufficient fuel or ammo is available, the Maritime Resupply will not activate.
  • Will activate regardless of where Hayasui (and Hayasui Kai) or Kamoi Kai Bo is in the fleet.
