Jets

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

Jet List

"Jets" refer to "Turbojet propelled planes".

Currently the game includes 4 planes with a turbojet:

• Kikka Kai, a "turbojet carrier-based fighter-bomber",
• Jet Keiun Kai, a "turbojet carrier-based fighter-bomber",
• Me 262 A-1a/R1, a "turbojet land-based fighter/interceptor",
  • So far it just behaves as a regular Interceptor,
• FR-1 Fireball, a mixed "piston engine propeller and turbojet carrier-based fighter",
  • So far it is just a regular Fighter.

In the following, only the Kikka Kai and Jet Keiun Kai will be treated as "jets", as they are the only ones having "jet behaviors".

• Rocket aircraft are also ignored as they have nothing to do with jets either, see here.

Mechanics

1. Two "jets" are currently available in the game, the Kikka Kai and the Jet Keiun Kai.

• Carrier jets have unique equipment icons : and respectively

2. Jets can only be equipped by Shoukaku Kai Ni A, Zuikaku Kai Ni A, Kaga Kai Ni Go, and Victorious Kai, and placed in Land-Based Air Squadrons.

3. Using jets will consume steel in addition to 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 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 .

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

Plane	Air State Modifier	Ship AA Modifier	Fleet AA Modifier
Jet Keiun Kai	0.6	0.5	0.7
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 Bombers nor Fighters, and so cannot activate the CVCI or take part in it.

Steel Cost

The steel consumption of jets is:

Steel consumption formula
[math]\displaystyle{ \text{Jet Phase Cost} = \sum^{\text{All Jets} } \lceil \text{Plane Count} \times \text{Steel Cost} \rceil }[/math] With [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: 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

1. 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.
2. They are "fighter-bombers" with a very hight 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 and Dive Bombing in-game, and among the only planes to provide Range .
   • This usefulness is relative, since they cannot be used in a CVCI.
3. 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

• From quests D21 & 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。
（※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.
(※Can be used in quests or equipment upgrading)

New Technology Aircraft Blueprint

• From quests D20 & 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。
※開発には複数図面必要です。
※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.
※ Can be used in quests and equipment upgrades.
