Introduction

Jets were introduced in the December 9th, 2016 Update. Jets possess the ability to perform a jet assault before the aerial combat phase.

Overview

Mechanics

1. Jets can only be equipped by Shoukaku-class Kai Ni A and place in Land-Based Air Squadrons.

2. Using jets will consume steel.

3. Having a jet equipped will allow a pre-emptive aerial attack known as Jet Assault.

Jets will still participate in the following aerial combat phase.
Damage during the jet assault is calculated the same way as dive bombers but damage during the airstrike phase is reduced.
- For LBAS jet assault, both jet assault and LBAS bombing use the lower multiplier.

4. Jets have shootdown resistance that reduces the losses to anti-air fire.

5. Jets will go through three different shoot down phases per normal battle.

Anti-air during jet assault.
Shoot down during air control.
Anti-air during normal airstrike.
It is unknown if the jet assault phase can trigger anti-air cut-ins.

6. Jets do not count as dive bombers for the purposes of activating Carrier Cut-In Attacks

Use Notes

1. Since they use the dive bomber multiplier and have a weaker airstrike, their use against targets larger than a heavy cruiser is limited.

2. They are two of the three fighter-bombers with shoot down resistance. This makes them useful when needing to maximise fighter power while maintaining some striking power. The Kikka Kai is fighter-bomber with the highest anti-air in game.

This usefulness is limited because they cannot be used to trigger CVCI.

3. The steel cost can add up very quickly. Especially when being equipped on the largest slots of Shoukaku and Zuikaku.

Note that equipping them in smaller slots limits their ability to contribute to air control and damage.

Steel Cost

The steel consumption of jets is:

[math]\displaystyle{ \text{Steel} = \lceil \text{Plane Count} \times \text{Steel Cost} \rceil }[/math]

[math]\displaystyle{ \text{Plane Count} }[/math] is the current plane count at the start of the battle.
[math]\displaystyle{ \text{Steel Cost} }[/math] is the steel cost per plane.
- Kikka Kai|: [math]\displaystyle{ 2.6 }[/math]
- Jet Keiun Kai: [math]\displaystyle{ 2.8 }[/math]

Important Notes

Take note that the costs are rounded up.
Jets only cost steel in nodes where they are used for jet assaults and airstrikes.
- Night battles will not cost steel.
Steel is consumed upon returning to base.
- This means jets can still be used even if you don't have enough steel for the sortie.
Because LBAS squadrons are refilled between waves, jets will always cost the full 18 planes per wave.

Acquiring Jets

Currently the only way to acquire Jets is by obtaining a few special items from Quests or from ranking that are necessary in order to produce the Kikka Kai and Jet Keiun Kai :

Ne-Type Engine
New Air Craft Plans
Prototype Keiun

Kikka Kai

The Kikka Kai is obtainable by completing the following quest chain. The total resources required are:

18,500 Steel
4,000 Bauxite
1x Ne-type Engine
2x New Aircraft Blueprint
3x Shiden Kai 2
2x Prototype Reppuu Late Model
2x Ryuusei

Completing this quest chain gives you an extra Ne-type Engine for upgrading the Keiun.
