Combat/Artillery Spotting

Introduction

Artillery Spotting is a means of increasing the damage your ships deal and their accuracy during the day, and manifests in either a double attack or a cut-in.

The following are universal requirements for a ship to perform artillery spotting:

• At least one slot of seaplanes must be equipped.
• Air superiority or supremacy must be achieved that battle.
• Ships cannot perform these while heavily damaged (大破).

The following ships are unable to perform artillery spotting either because of a 0 plane capacity or the inability to equip any appropriate setups.

• All destroyers
• Torpedo cruisers (Kitakami, Ooi and Kiso Kai Ni)
• Certain light cruisers (Isuzu Kai Ni, Tenryuu, Tatsuta and Yuubari)
• Submarines
• All carriers
• Auxiliary vessels Akashi and Akitsu Maru

Equipment Setups

Attack Mode	Prerequisite	The Remaining Slot	Damage Modifier	Trigger Chance
Double Attack		Any auxiliary equipment	120% x 2	~50%
Double Attack			120% x 2	Additional 3%~10% ?
Double Attack			120% x 2	Additional ~6% ?
Cut-In		Any auxiliary equipment	110%	~50%
Cut-In ( Radar )		-	110%......(Sec.Gun) ? 120%......(RADAR)	Additional 22%~30% ?
Cut-In ( AP Shell )		-	110%......(Sec.Gun) ? 130%......(AP SHELL)	Additional ~20%
Mixed Attack (AP)		-	120% x 2.....(DA) 150%...........(CI)	~70% (Total)
Mixed Attack (Sec.Gun)		-	120% x 2.....(DA), 110%...........(CI) ?	~70% (Total)

• The slot order does not matter, though be mindful that putting your planes in a ship's largest slot can improve your chances of triggering a special attack.
• When neither special attack is triggered, the ship will just do a single attack, dealing 100% damage.

Trigger Chance

• The flagship has ~15% higher chance in triggering Artillery Spotting.
• Losing Air Supremacy (AS+) to Air Superiority (AS) will lower the trigger chances by ~12%. Higher penalty for mixed attack.
• Higher fleet total LoS (Line of Sight) will slightly increase the chances, around 5% ~ 10% per 100 additional FLoS. Notice that FLoS equals to the sum of LoS stats from all the ships in your fleet. Bonuses from equipment are included in the calculation.
• Certain equipment set-ups provide a higher chance of triggering.
