Foreign Plane Bonuses have returned and should be examined when planning equipment setups. The following bonuses are applied:

• Ships using planes get bonuses based on the different categories of bonuses ɑ/ß/γ, A, and B.
  • The ɑ/ß/γ groups are the general foreign plane bonuses, being divided into three "levels" (γ>ß>ɑ) and being both map-wide and node-specific,
  • Group A are French and British bonuses divided into three sub-categories:
    • A1 are French seaplanes,
    • A2 are British seaplanes,
    • A3 are Swordfish.
  • B# bonuses are primarily for LBAS (with ship-based & land-based planes), with the ship-based planes also providing the same bonuses to ships, and being divided into two "levels" (B2>B1)

Notes

• These bonuses work for all ships and for all attack types, including: LBAS, jet assault, airstrikes, air/surface shelling, and night attacks.
• Bonuses from a same line or column do not stack.
• Map-wide bonuses and node-specific bonuses always stack.
• Bonuses still work for planes equipped in 0-slot for ships.
• Bonuses do not work on 0-slot for LBAS.

  • On the 2024-07-31 update, the FR-1 Fireball/SB2C-5 bug has been fixed and other bonuses have been added.
  • On the 2024-08-08 update, the new USN bonuses have been added on release.

Tips

• Carriers:
  1. Try to equip one plane from each column and row
  2. For example: ɑ/A3 + ß/B1 + γ/B2
  • This also applies to ships that carry multiple plane types in normal setups.
• Other Ship Types:
  • As only one seaplane is generally equipped on a ship, pick γ>ß>ɑ and then the highest bonus among groups A or/and B depending on the node.

• For Group 1, Group 2, and Group 3 bonuses, having one equipment from the group is enough to have the bonus.
  • Equipping a second gear from the same group will not provide any additional bonus.
  • The bonus groups stack with each other.
• Do not confuse the balloon mechanic fleet-wide buff with this event bonus that only buffs the individual ship equipped with it.
