Anti-Air Cut-in

Using special equipment setups, ships may perform one of multiple special anti-air maneuvers during Stage 2. These moves are often referred to as AA Cut-ins, or AACI due to the way the equipment is displayed in the screen before they are performed. Particular AACI are often referred to by their acronym, such as BBR for AACI 5.
AACI grants a multiplier to the Fixed Shootdown of all Allied Fleet ships regardless of what ship uses it, referred to as K-value. On top of that effect, AACI will remove a fixed number of planes from each enemy bomber slot. These effects make depleting the entirety of enemy bombers much more feasible.
Although several ships can be equipped with a proper AACI setup, only one ship can perform an AACI. If Stage 2 happens multiple times, like in an Air Battle node, then each Air Phase's Stage 2 might roll an AACI.
If the enemy fleet has a valid setup, it may as well activate an AACI. If that happens, an animation will not be shown, but the effects will function normally. It can activate during the regular airstrike phase, but not during LBAS phases.
- There is a bug that allows enemy ships to activate AACI even if they were sunk[1].
The trigger chance of a given AACI is solely determined by its ID (its API value), and is arbitrary. Fleet AA, Ship AA, Adjusted AA, Air State, or any other parameter like Luck and LoS have no bearing in AACI trigger rates. Most trigger chances were datamined from KanColle Vita, and tests in the Browser version corroborated the results.

- Notes
- If multiple ships can trigger AACI, the ship that rolls the highest ID number takes priority.
- If ID numbers are tied, priority goes by fleet slot order from top to bottom.
- If a single ship fulfills multiple AACI requirements:
- A single roll is done to check for all AACIs.
- This means that an AACI with higher priority and higher trigger rate completely blocks lower priority AACI from activating.
- For example, Akizuki with a 8+ AA 8+ AA Air setup fulfills the requirements of the AACIs with ID 1, 2, 3, 5, and 8, with 1 being the highest priority. Due to this, the only ID that Akizuki can trigger is 1, because a success will activate it, and a failure implies that the roll wouldn't meet the 58%, 50%, 55%, and 50% trigger rates as it has failed to meet a 65% rate roll.
- For example, Akizuki with a
- Conversely, an AACI with lower priority but higher trigger rate has a chance of occurring, if the roll fails to pass the higher priority AACI.
- For example, Isokaze B Kai with 8+ AA 8+ AA Air fulfils 5 (55% rate) and 29 (60% rate), with 5 having priority. This means that in total, 5 will occur 55% of the time, and 29 will occur the leftover 5% of the time (60% - 55%).
- For example, Isokaze B Kai with
- Priority is: (1 > 2 > 3, 10 > 11, 14 > 15, 16 > 17, 19, 21, 25, 42 > 43 > 44 > 45) > 4 > 5 > 6 > 8 > 7 > (26 > 27 > 28, 29) > 9 > (33) > 12 > 13 > (18, 20, 22, 23, 30 > 31 > 24, 32)[2][3]
- Examples:
- Kinu Kai Ni can trigger both ID 20 and 19.
- The same ship can activate IDs 20, 5, and 29.
- Note: At some point during 2018-2019(?), priority was changed from 7 > 8 to 8 > 7. Prior to this, both 7 and 8 could be triggered with 8+ AA Air[4], whereas now only 8 can be triggered.
- Examples:
Sequential AACIs
The Sequential AACIs are the Cut-ins introduced with the implementation of Johnston onwards. So far, they are exclusive to the Fletcher-class and Atlanta-class
. Different from Original AACIs, each eligible AACI will be rolled independently if the previous roll has failed. If all Sequential rolls fail, an additional Original Type roll is performed. This grants the specific ships with access to Sequential AACIs extremely high combined trigger rates.
- Example: Atlanta with 5inch Twin CD + 5inch Twin CD + GFCS fulfils 39, 40, 41, and 5. Rolled independently, this gives 57% for 39, ~24% for 40, ~10.4% for 41, ~4.7% for 5, for a total of ~96% chance of some AACI occurring.
Sequential AACIs are, in order of priority: (34 > 35 > 37 > 36, 38 > 39 > 40 > 41) > (Original AACI)[2]
