This page studies the trigger rates & effectiveness of Artillery Spotting (弾着観測射撃), based on preliminary in-game testing. An optimal use of Artillery Spotting could considerably improve your fleet's daytime combat performances. In brief, Artillery Spotting (aka. Day Battle Special Attacks) consists of two types of attack: Cut-In [CI] & Double Attack [DA]. When activated, the attacking ship receives a damage output (post-cap) & accuracy bonus. Please note that the bonus is NOT directly applied to the actual damage taken, but your ship's attack power. You need to achieve at least Air superiority (AS) during aerial combat, and at least 1 seaplane equipped on the ship. The remaining plane count can't be 0. More details could be found on the page Game Mechanics -> Artillery Spotting .
