Introduction

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。
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。
本改良型は従来型より性能向上、また発煙装置を複数投入することで、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！

An improved shipboard smoke generator that creates a "smoke screen" hiding the fleet from enemies.
It is mainly used by small ships such as destroyers, and by generating a large "smoke screen", it obstructs the direct sights of enemy artillery and bombing attacks, protecting the fleet.
This improved version has better performance than the previous model, and by installing multiple smoke generators, it is possible to deploy a denser smoke screen.
※Be careful when attacking enemies equipped with radars!

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 the Shelling phase.

The 3 different smoke size

• The trigger rate depends on:
  • The number of "Smoke Generators" in the fleet,
  • The flagship Level and Luck (secretary for Combined Fleets),
  • improvements of the generator.
• Regarding the equipment:
  • Each Smoke Generator (Smoke Screen) counts as 1,
  • Each Smoke Generator Kai (Smoke Screen) counts as 2,
  • improvements of the generator can also count as 1 ([1][2]).
• There is no formula yet, but a measure of trigger rate can be found here: [3].
• 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 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.
