Anti-Air Cut-in

Akizuki performing the ID 1 AACI.

Using special equipment setups, ships may perform one of multiple special Anti-Ait Cut-In mostly referred to as AACI, during Stage 2.

AACI types

• Each AACI is defined by its "ID" (its API value), and is arbitrary (see the below table).
  • They are then mostly referred to by their "ID".
  • Some older AACI may be referred to by their abbreviation, such as BBR for AACI 5.
• For all AACI, the "ID" therefore fully determines:
  • The setup of the AACI and the ships able to trigger it,
  • The "Trigger Rate" and the "Priority Order",
  • The "K-value" and "shot down per slot" value,

AACI effects

• Grant a multiplier to the "Fixed Shootdown" of all allied ships, referred to as the K-value, regardless of what ship triggers it,
• Remove a fixed number of planes from each enemy bomber slot ("shot down per slot").

These effects make depleting the entirety of enemy planes much more feasible.

AACI triggering

• Only one AACI can be performed per battle,
  • On "Aerial Combat Nodes", AACI can be triggered twice, one per phase.
• Only a ship equipped with proper AACI setups can trigger one (see the below table),
• If multiple ships are equipped with AACI setups, each ship will roll their available AACI in ID's "Priority Order" (see the below table).
  • If IDs are tied, priority goes by fleet order from top to bottom.
  • Thus, for a given fleet & setup, some ships will take priority over others always the same way.
  • If one ship fulfills the requirement for multiple setups at once, then it will be able to roll each individual AACI in ID's "Priority Order".
• The trigger rate is unaffected by Stats like the damage status, Fleet AA, Ship AA, Adjusted AA, Air State, or any other parameter like Luck and LoS.

• It is possible for all AACI rolls in a fleet to fail, triggering no AACI.
• If the enemy fleet has a valid setup, it may as well activate an AACI. If that happens, no animation will be shown, but the effects will function normally.
  • It can activate during the regular airstrike phase, but not during other phases like the Jet Assaults, LBAS phases, OASW, or Shelling phases.
  • There is a bug that allows enemy ships to activate AACI even if they were sunk.

For the following table:

• is used to indicate any Large Caliber Main Gun
• is used to indicate any High-Angle Gun (dual-purpose guns/HA guns), including Main HA Guns and Secondary HA Guns,
• is used to indicate any AA Gun,
• is used to indicate any AA Fire Directors
  ,
• is used to indicate any AA Shell
• is used to indicate any Radar, including Surface Radars,
• Air is used to indicate an Air Radar (any Radar with AA stat of 2 or higher).

Do note that some setups also required a maximal or minimal base AA stat for the equipment to be counted.

• This exclude any stat gained from Fit Bonuses or Improvement.

Examples

• Akizuki with 8+ AA8+ AAAir fulfills the requirements of the AACIs with ID 1, 2, 3, 13 (in this order).
  • The resulting trigger rate is 95.22%.

• Fletcher with fulfills 34, 35, 8, 9 (in this order).
  • The resulting trigger rate is 93.93%.

• Musashi with Sp fulfills 42, 43, 44, 45, 5, 28, 8, 13 (in this order)
  • The resulting trigger rate is 99.73%.

• Isokaze B Kai with 8+ AA8+ AAAir fulfills 29, 5, 8, 13 (in this order)
  • The resulting trigger rate is 94.15%.

Sequential AACIs

The Sequential AACIs were the AACIs introduced with the implementation of Johnston, allowing to a single ship to roll multiple AACI IDs at once, greatly increasing the trigger rate. Since the 26/05/2023 update, this mechanic is defunct, being available to all ships.
