→Setups and Attack Types
{{CombatPortal}}
Artillery Spotting, commonly referred to as ''ArtySpot'', ''Daytime CI'', or simply ''Spotting'', is a series of special attacks that allow ships with specific equipment setups to perform Cut-in attacks during the Day Battle. These attacks grant '''post-cap''' damage bonuses as well as increased shelling accuracy.
The following ships are unable to perform artillery spotting either because of a 0 plane capacity or the inability to equip any appropriate setups.
The Carrier-equivalent for Artillery Spotting is '''Aircraft Carrier Cut-in (CVCI)'''. Mechanically, they share the same core mechanics, but have different trigger conditions.
==Equipment Setups==
=Artillery Spotting=
{| class="wikitable"
Artillery Spotting is a feature for ships that can launch {{Seaplane}} [[Seaplane]]s. Using special equipment setups, those ships may perform one of multiple special attacks. These attacks are often referred to as Cut-ins due to the way the equipment is displayed in the screen before the attacks are performed. Particular Cut-ins are often referred to by their acronym, such as APCI for Main AP Shell Cut-in, Sec CI for Secondary Gun Cut-in, etc.
Cut-ins may be activated during a ship's turn and will override its normal shelling attack. Do note that the specific equipment being shown during the Cut-ins have no influence on the damage output.
==Trigger Conditions==
[[File:Air_Superiority_Aquired.png|thumb|right|The fleet attains Air Supremacy. Artillery Spotting and Aircraft Carrier Cut-ins can now be performed]]
* The fleet must have attained {{color|green|'''Air Superiority (AS)'''}} or {{color|green|'''Air Supremacy (AS+)'''}} Air State.
** For details on Air State, please refer to [[Aerial Combat#Stage 1 - Battle for Air Superiority|Aerial Combat - Stage 1]]
* The ship must be equipped with at least one {{SPR}}[[SPR|Seaplane Recon]] or {{SPB}}[[SPB|Seaplane Bomber]] on a slot with size '''higher than 0'''.
** {{SeaplaneFighter}} [[SPF|Seaplane Fighters]] or {{YellowPlane}} [[:Category:Carrier-based Reconnaissance Aircraft|Reconnaissance Aircraft]] '''do not''' enable Artillery Spotting.
** '''Main Suisei Cut-in''' specifically ignores this condition.
* The ship must be equipped with at least one {{RedGunHeavy}}{{RedGunMedium}}{{RedGunLight}}{{Main Green}} '''[[Main Gun]]'''.
* The ship must target another ship and attack it with Surface Shelling.
** ASW shelling has no Artillery Spotting setups.
* The ship must not be {{color|red|'''Heavily damaged (大破)'''}}
==Setups and Attack Types==
[[File:Main_Main_Cutin.png|thumb|right|Musashi performing Main AP Shell Cut-in (APCI)]]
Different setups have different conditions, trigger rates, damage, and number of hits. Cut-ins are determined by the attack's prerequisites as well as the previously stated trigger conditions.
For a given Cut-in, any other equipment can be added on the remaining slots. Be wary that adding certain equipment may change the Cut-in that will be rolled. Meeting prerequisites for multiple Cut-ins grants each a chance to be activated: in this case, the Cut-ins will be rolled in order of priority from '''top to bottom'''.
For clarity purposes:
* {{Large Gun}} is used to indicate a '''[[Main Gun]]''' of ''any size'',
* {{Seaplane}} is used to indicate a '''"[[Seaplane]]" ''' ([[SPR|Recon]] or [[SPB|Bomber]]),
* {{Sec Gun}} is used to indicate a '''[[Secondary Gun]]''' of ''any size'',
* {{AP Shell}} is used to indicate an '''[[AP Shell]]''',
* {{Radar}} is used to indicate a '''[[Radar]]''' of ''any type'',
* {{RedPlane}} is used to indicate any '''{{Equipment/Link|Suisei Model 22 (634 Air Group)|Suisei Model 22 (634 Air Group/Skilled)|Suisei Model 12 (634 Air Group w/ Type 3 Cluster Bombs)|text="634 Air Group" Suiseis}}'''.

* If all rolls fail or the ship meets no Cut-in requirements, then it'll perform a Single Attack: a default 1 hit, no damage modifier shelling attack.
* If an Artillery Spotting attack is evaded, it will deal [[Damage_Calculations#Chip_Damage|chip damage]] instead.
* If valid set-ups for both Suisei-CI and Zuiun-CI are used, only the Zuiun-CI may trigger.
=Aircraft Carrier Cut-In=
Aircraft Carrier Cut-in, or CVCI for short, is a feature for ships that can launch {{BluePlane}}{{RedPlane}}{{GreenPlane}}Carrier-based planes. Similar to Artillery Spotting, using special equipment setups, those ships may perform one of multiple special attacks.
CVCI may be activated during a ship's turn and will override its normal shelling attack.
==Trigger Conditions==
* The fleet must have attained <span style="color:green;">'''Air Superiority (AS)'''</span> or <span style="color:green;">'''Air Supremacy (AS+)'''</span> Air State.
** For details on Air State, please refer to [[Aerial Combat#Stage 1 - Battle for Air Superiority|Aerial Combat - Stage 1]]
* The carrier must fulfill one of the equipment setups.
* The carrier must be shelling a '''surface ship'''.
** Installations cannot be attacked by CVCI.

*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.
* If all rolls fail or the ship meets no Cut-in requirements, then it'll perform a Single Attack: a default 1 hit, no damage modifier shelling attack.
*When neither special attack is triggered, the ship will just do a single attack, dealing 100% damage.
* If a CVCI attack is evaded, it will deal [[Damage_Calculations#Chip_Damage|chip damage]] instead.
'''Note:''' The Critical Damage modifier granted by Aircraft [[Proficiency#Critical Bonus|Proficiency]] works differently when performing a CVCI.
=Trigger Rates=
Artillery Spotting and Aircraft Carrier Cut-Ins share the same trigger rate formula. The chance of successfully rolling and triggering a cut-in is mainly affected by the [[Air State]] and the "raw [[LoS]]", as well as some other factors like the type of CI, the ship's luck, and the Recons/Bombers currently in the fleet.
===Trigger Chance===
{|class="wikitable mw-collapsible mw-collapsed" width="100%"
!colspan=2|Trigger Rates
|-
*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.
