Equipment Bonuses

For Group 1 and Group 2 bonuses, having one equipment from the group is enough to have the bonus. Having a second one do nothing.
Do not confuse the balloon mechanic that buff the whole fleet with this event bonus that only buff ships equip with it.

The bonus from each group is stackable.

Planes sudoku Bonuses

Plane bonuses similar to the Summer 2021 & 2022 events have returned and should be examined when planning equipment setups. The following bonuses are applied:

Ships using planes get bonuses based on the numbers 1, 2, and 3,
Land-bases using planes get bonuses applied to all bombers in the individual base, based on the letters A and B.

Notes

Those bonuses work for all ships and for all attack types, including LBAS, airstrikes, air/surface shellings, and night attacks.
Bonuses from a same line do not stack.
