'''Notes:'''

'''Notes:'''

 

* '''If multiple ships can trigger AACI, the ship that rolls the highest API number takes priority.'''

* '''If a ship fulfils multiple AACI requirements, the API with the highest priority will be checked first.'''

** A single roll is done to check for all AACIs. This means that an AACI with lower priority but higher trigger rate can be activated.

* '''If a single ship fulfils multiple AACI requirements:'''

*** The opposite cannot occur.

** A '''single roll''' is done to check for all AACIs.

** For example, Akizuki with a {{GreenGunBuiltIn}}{{GreenGunBuiltIn}}{{Radar}} setup fulfills the requirements of the AACIs with API values 1, 2, 3, 5 and 8, with 1 being the highest priority. Due to this, the only API 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.

** This means that an AACI with higher priority and higher trigger rate completely blocks lower priority AACI from activating.

* AACI priority is not completely determined, but some have been observed:

*** For example, Akizuki with a {{GreenGunBuiltIn}}{{GreenGunBuiltIn}}{{Radar}} setup fulfils the requirements of the AACIs with API values 1, 2, 3, 5 and 8, with 1 being the highest priority. Due to this, the only API 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.

** 8 has a lower priority than 7, as both can be triggered by the same ship.

** 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.

** [[Kinu|Kinu Kai Ni]] can trigger both API 20 and 19.

*** For example, Isokaze B Kai with {{GreenGunBuiltIn}}{{GreenGunBuiltIn}}{{Radar}} 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%).

** The same ship can activate APIs 20, 5 and 29.

** Priority is: '''(1 > 2 > 3, 10 > 11, 14 > 15, 16 > 17, 19, 21, 25) > 4 > 5 > 6 > 8 > 7 > (26 > 28, 29) > 9 > (33) > 12 > 13 > (18, 20, 22, 23, 30 > 31 > 24, 32)'''<ref name="aaci1">https://docs.google.com/spreadsheets/d/1YUppVErQj7P9f9-ddpdR-e7fTaycjSK9-x4GE9ibCrA/edit#gid=1156988467, TsunDB</ref>

* '''If multiple ships trigger AACI, the ship that rolled the highest API number takes priority.'''

**** [[Kinu|Kinu Kai Ni]] can trigger both API 20 and 19.

**** The same ship can activate APIs 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 {{GreenGunBuiltIn}}{{AntiAircraftFireDirector}}{{Radar}}<ref>https://gyazo.com/2472468c10c0dacd28a493a79ff140da</ref>, whereas now only 8 can be triggered.

===Sequential AACIs===

===Sequential AACIs===

The '''Sequential AACIs''' are the Cut-ins introduced with the implementation of [[Johnston]] onwards. So far, they are exclusive to the {{Ship/Link|Fletcher/Kai|Johnston/Kai|text=Fletcher-Class}} and {{Ship/Link|Atlanta/Kai|text=Atlanta-class}}. Different from Original AACIs, from lowest to highest API, 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 trigger rates.
