{{CombatPortal}}

Jets were introduced in the [[Game Updates/2016/December 9|December 9th, 2016 Update]]. Jets possess the ability to perform a [[Aerial Combat#Jet_Assault_Phase|Jet Assault]] before the aerial combat phase.

In their current form, "Jets" refer to "[[wikipedia:Turbojet|Turbojet]] propelled fighter-bombers".

=Mechanics=
1. Two "jets" are currently available in the game, the {{Equipment/Link|Kikka Kai}} and the {{Equipment/Link|Jet Keiun Kai}}.
*Both jets have unique equipment icons : {{JetFighterBomber2}} and {{JetFighterBomber1}} respectively
*Despite being propelled by one jet engine, the [[FR-1 Fireball]] has nothing to do with "jets" in the game and is seen as a regular fighter.

2. Jets can only be equipped by {{ShipLink|Shoukaku Kai Ni A}}, {{ShipLink|Zuikaku Kai Ni A}}, {{ShipLink|Kaga Kai Ni Go}}, and {{ShipLink|Victorious Kai}}, and placed in [[Land-Based Air Squadron]]s.

3. Using jets will consume steel{{steel}} in addition to bauxite{{bauxite}}.

4. Having a jet equipped will allow a pre-emptive aerial attack known as '''[[Jet Assault]]''' (JA).
* Jets will still participate in the following aerial combat phases.
* [[Damage_Calculations#Airstrike|Damage]] during the jet assault is calculated the same way as dive bombers (x1.0), but damage during the airstrike phase is reduced (x0.7071).
** For LBAS jet assault, '''both''' jet assault and LBAS bombing use the lower multiplier. 

5. Unlike most planes, both jets are '''Long [[Range]]''' {{Range}}.

6. Jets have a high [[AAR|Anti-Air Resistance]] that reduces losses to anti-air fire.

|- 
|{{JetFighterBomber2}}{{Equipment/Link|Kikka Kai}}||0.6||0.5||0.5
|}

7. Jets will go through '''three''' different shoot-down phases per normal battle.
* Anti-air during the Jet Assault.
* Shoot down during Air Control.
* Anti-air during the normal airstrike.
The jet assault phase cannot trigger [[AACI]].

8. Jets '''do not count''' as [[Dive Bomber]]s nor [[Fighter]]s, and so cannot activate the [[CVCI]] or take part in it.

===Steel Cost===
The steel consumption of jets is:

<math>\text{Jet Phase Cost} = \sum^{\text{All Jets}} \lceil \text{Plane Count} \times \text{Steel Cost} \rceil</math>

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

'''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 when having not enough steel for the sortie.
* Because LBAS squadrons are refilled between waves, jets will always cost the full 18 planes per wave.

==Use Notes==
#Since they use the dive bomber multiplier and have a weaker airstrike per plane, making their use against larger targets is limited if used alone.
#They are "fighter-bombers" with a very hight [[Aerial_Combat#Anti-Air Resistance|AA resist]]. This makes them useful when needing to maximize fighter power while maintaining some striking power. 
#*Jets are the fighter-bombers with the highest AA {{AA}} and Dive Bombing {{Dive}} in-game, and among the only planes to provide Range {{Range}}.
#*This usefulness is relative, since they cannot be used in a [[CVCI]].
#The steel cost can add up very quickly, especially when being equipped on the largest slots of the CV.
#*Note that equipping them in smaller slots limits their ability to contribute to air control and damage.

=Acquiring Jets=
Currently, the only way to acquire Jets is by obtaining several special items from Quests or [[ranking]], that are necessary to obtain the [[Kikka Kai]] and produce the [[Jet Keiun Kai]] :

==Ne-Type Engine==
<div style="float:right">{{Item/Card|Ne Type Engine|size=150px|link=file}}</div>
*From quests {{Q|D21}} & {{Q|F47}}.
===Description===
新開発の燃焼噴射推進器です。日本発の実用ジェットエンジンとして戦力化が期待されます。<br>（※後日改装任務で使用可能）

''A newly developed combustion jet propulsion. There are high expectations for its transformation into combat potential as a Japanese-developed production-ready jet engine.<br>(※Can be used in quests or equipment upgrading)

==New Technology Aircraft Blueprint==
<div style="float:right">{{Item/Card|New Technology Aircraft Blueprint|size=150px|link=file}}</div>
*From quests {{Q|D20}} & {{Q|G5}}.
===Description===
新型航空機の開発、戦力化するために必要な技術図面です。<br>※開発には複数図面必要です。<br>※任務や装備改修で使用可能。

''These are the technical drawings required to develop and field a new type of aircraft. ※ Multiple drawings are required for development.<br>※ Can be used in quests and equipment upgrades.

==Item quests==
Those items are notably given in the following quest chains:
*{{Q|F43}}+{{Q|A62}}>{{Q|F45}}>{{Q|F46}}
*{{Q|D2}}+{{Q|D6}}>{{Q|D20}}>{{Q|D21}}>{{Q|F47}}
