Equipment Bonuses

For Group 1 & Group 2 bonuses, having one equipment from the group is enough to have the bonus. Having a second one does 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.

Equipment		Damage C2/Q	Against CV Summer Demon	Against BB Summer Princess
Barrage Balloon		1.06x each (stackable with below)	-
Group 1	Barrage Balloon Ka-Mi tank Toku DLC + 11th DLC + Panzer II Toku DLC + Chi-Ha Toku DLC + Chi-Ha Kai 14inch/45 Guns	1.05x
Group 2	Toku DLC + Ho-Ni tank Toku DLC + Panzer III M4A1 DD	1.08x
AP Shells		-	1.1x	1.2x
Bomber SPB SPF			1.1x
Swordfish			1 = 1.10x 2 = 1.32x
Dive Bombers			1 = 1.10x 2 = 1.21x	-

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.
