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,
  • All those parameters are fully arbitrary.


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,
  • 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[1].


For the following table:

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

Examples
  • Akizuki with  8+ AA 8+ AA Air  fulfills the requirements of the AACIs with ID 1, 2, 3, and 13 (in this order).
    • The resulting trigger rate is ??
  • Fletcher with      fulfills 34, 35, 8, 9 (in this order).
    • The resulting trigger rate is ??
  • Musashi with     Sp fulfills 42, 43, 44, 45, 28 (in this order)
    • The resulting trigger rate is ??
  • Isokaze B Kai with  8+ AA 8+ AA Air  fulfills 29, 5, 8, 13 (in this order)
    • The resulting trigger rate is ??


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.
