敵から艦隊を隠す「煙幕」を発生させる艦載発煙装置の改良型です。
An improved shipboard smoke generator that creates a "smoke screen" hiding the fleet from enemies.
Smoke Generators
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 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 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 day battle.
The 3 different smoke size
The trigger rate depends on:
Regarding the equipment:
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.

The X coefficient is unclear yet, being about 0.04~0.045.

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 near 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 .
Behave as if it was 2 base Smoke Generator (Smoke Screen) at once.

Smoke Generators can be used in combat to deploy a smoke screen.
improvements also affect the maximum smoke level possible.
