Is a "Fleet Oiler" (AO), despite being designated in the game as a "Special Escort Carrier" (CVE / 特護空 / 特設護衛空母), and being historically one.

• This is reflected in her equipability exceptions and ASW capability.

Gameplay Notes

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

• They can also carry various support equipment, which can be useful for Resource Farming.

Special Mechanics

Kai

• When equipping at least 1 Dive Bomber , her attack formula for day shelling follows the Carrier Shelling formula.
  • This also makes her unable to attack submarines at night.

• Similarly to CVN, when equipping at least 1 Night Dive Bomber , her night attacks become Carrier Night Air Attacks.
  • She cannot trigger the attack when Chuuha.
