This category contains all equipment or equipment types classified as Smoke Generators.

This category is populated by Template:EquipmentCategoriesKai. Please do not manually add pages to this category.

Mechanics

Smoke Generator Smoke Generators can be used in combat to deploy a smoke screen.

Example of a large smoke deployed.
  • There are 3 smoke screen sizes, being Small < Medium < Large.
    • The maximum smoke size that can be generated is dependent on the number of smoke generators, being respectively 1/2/3.
    • Note that Improved improvements also affect the maximum smoke level possible.
  • It sharply reduces the accuracy of all fleets, proportionally to the smoke screen size (the hit rate is still capped at 11%).
    • This effect can be partially bypassed by using radars (both sides).
  • The effect will last for the day battle, even so the animation will fade before the battle's end.

Smoke activation button next to the Formation ones.
  • If equipped, it can be activated with a specific button when selecting the formation.
    • It can be activated multiple times per sortie until it triggers, being triggerable once, in day battle only.
  • It cannot be activated in Exercises in the current implementation.
  • The trigger rate is not 100% and depends on the fleet's flagship's luck Luck, as well as the amount and type of Smoke Generators used.
    • For combined fleets, it is the luck of the main flagship.
    • The size of the triggered smoke screen depends on how many smoke generators are used.
  • It will only trigger at the beginning of the Shelling phase.

The 3 different smoke size

Two formulas have been determined to approximate the trigger rate of smoke screens.

  • The 2nd formula is based on the 1st one with additional hypothesis,
  • A measurement of the trigger rate can be found here,
  • Both formulas can be directly compared here.
  • It is possible to have a total trigger rate for all 3 sizes of 100%, giving the FS has enough luck & enough generators are used.
Trigger Rate Formula 1 [3]

  • If [math]\displaystyle{ \text{Luck}_\text{flag} ≥ 1 \text{ & } \text{N}_\text{Generator} ≥ 3 }[/math], then [math]\displaystyle{ \text{P}_\text{0} = 0 }[/math]
[math]\displaystyle{ \text{K} = \bigg\lceil \sqrt{ \text{Luck}_\text{flag} } + 0.3 \times \bigstar_\text{base} + 0.5 \times \bigstar_\text{Kai} \bigg\rceil }[/math]
[math]\displaystyle{ \text{N}_\text{Generator} = 1 }[/math] [math]\displaystyle{ \text{N}_\text{Generator} = 2 }[/math] [math]\displaystyle{ \text{N}_\text{Generator} ≥ 3 }[/math]
[math]\displaystyle{ \begin{align} \text{P}_\text{1} = 1 - \text{P}_\text{0} \\ \text{P}_\text{2} = 0 \\ \text{P}_\text{3} = 0 \end{align} }[/math]
[math]\displaystyle{ \begin{align} \text{P}_\text{1} = 1 - \text{P}_\text{0} - \text{P}_\text{2} \\ \text{P}_\text{2} = 0.5 \times ( 1 - \text{P}_\text{0} ) \times ( \text{K} + 2 ) \\ \text{P}_\text{3} = 0 \end{align} }[/math]
[math]\displaystyle{ \begin{align} \text{P}_\text{1} = 1 - \text{P}_\text{2} - \text{P}_\text{3} \\ \text{P}_\text{2} = mini ( 0.3 ; 1 - \text{P}_\text{3}) \\ \text{P}_\text{3} = X \times \text{K} + 0.15 \times ( \text{N} - 3 ) \end{align} }[/math]
  • The X coefficient is unclear yet, being about 0.04~0.045.
With
  • [math]\displaystyle{ \text{N}_\text{Generator} }[/math] the amount of Smoke Generators:
  • [math]\displaystyle{ \text{Luck}_\text{flag} }[/math] the flagship's luck,
  • [math]\displaystyle{ \bigstar_\text{base} }[/math] the total improvement Improved level of the base generators,
  • [math]\displaystyle{ \bigstar_\text{Kai} }[/math] the total improvement Improved level of the Kai generators,
Trigger Rate Formula 2 [4]
[math]\displaystyle{ \text{K} = 1.5 \times \sqrt{ \text{Luck}_\text{flag} } + 0.3 \times \bigstar_\text{base} + 0.5 \times \bigstar_\text{Kai} }[/math]

[math]\displaystyle{ \begin{align} \text{Level 1}_\text{Rate %} = ? \\ \text{Level 2}_\text{Rate %} = ? \\ \text{Level 3}_\text{Rate %} = ? \end{align} }[/math]
[math]\displaystyle{ \begin{align} \text{Level 1}_\text{Rate %} = ? \\ \text{Level 2}_\text{Rate %} = 3 \times \bigg\lceil 5 \times \text{N}_\text{Generator} + \text{K} - 5 \bigg\rceil + 1 \\ \text{Level 3}_\text{Rate %} = ? \end{align} }[/math]
[math]\displaystyle{ \begin{align} \text{Level 1}_\text{Rate %} = 100 - \text{Level 2}_\text{Rate %} - \text{Level 3}_\text{Rate %} \\ \text{Level 2}_\text{Rate %} = 30 \\ \text{Level 3}_\text{Rate %} = 3 \times \bigg\lceil 5 \times \text{N}_\text{Generator} + \text{K} - 15 \bigg\rceil + 1 \end{align} }[/math]
  • If [math]\displaystyle{ \text{Level 3}_\text{Rate %} ≥ 70 \text{ %} }[/math], then [math]\displaystyle{ \text{Level 2}_\text{Rate %} }[/math] is reduced for the total of the three rates to be at 100 %.
With
  • [math]\displaystyle{ \text{N}_\text{Generator} }[/math] the amount of Smoke Generators:
  • [math]\displaystyle{ \text{Luck}_\text{flag} }[/math] the flagship's luck,
  • [math]\displaystyle{ \bigstar_\text{base} }[/math] the total improvement Improved level of the base generators,
  • [math]\displaystyle{ \bigstar_\text{Kai} }[/math] the total improvement Improved level of the Kai generators,

  • The smoke gives an Accuracy malus to both fleets when used:
    • Please note that these are initial estimations and are subject to change.
    • It is currently unknown if the airstrike accuracy is affected by the smoke.
    • Some modifiers are impossible to determine because the fleet hit the lower bound hit rate (11% hard cap).
    • There are some inconsistencies between "old" and "new" enemies.
    • Having a (surface ?) radar equipped reduces the smoke effect for both fleets, but only for the shelling phase.

  • AA effects:
    • The smoke affects the allied shootdown but not the enemy shootdown.
    • No fixed shootdown above 2 has been observed under a smoke.
    • The guaranteed shootdown does not seem to be affected.
    • A modifier to the Adjusted AA is suspected but there is not enough data to confirm it.
  • The Smoke reduce the Anti-Air Rocket Barrage trigger rate either directly or by reducing the Adjusted AA.
