Introduction
敵から艦隊を隠す「煙幕」を発生させる艦載の発煙装置です。
主に駆逐艦などの小型艦で運用し、大きな「煙幕」を発生させ
ることで敵の砲撃や爆撃の光学照準を阻害、艦隊を守ります。
多数投入することで、より濃密な煙幕を展開させることも可能
です。
※電探装備の敵の攻撃には注意が必要です！

Mechanics
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
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
, 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 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 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.
- It has been observed that in some cases, the Yamato-class and Nagato-class (but not Nelson-class) Special Attacks may still have decent accuracy despite smoke being active[1]. This may possibly be due to the attack's accuracy mod (which are currently unknown) overcoming the smoke's penalty mod.

- 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.
