==Introduction==
+
{{CombatPortal}}
−
Jet planes are a new type of plane that have been introduced to Kantai Collection as of the [[Game Updates/2016/December 9|December 9th, 2016 Update]]. Unlike normal planes, Jet planes are able to attack ''twice'' during the Aerial Phases they take part in. In addition, only [[Land-Based Air Squadron|Land-Based Air Squadrons]] and '''Armored Carriers'''* such as [[Shoukaku|Shoukaku Kai Ni A]] and [[Zuikaku|Zuikaku Kai Ni A]] can use these they jet planes and when in use they will consume steel along with other resources.
 
  
−
(*Evidence so far suggests that [[Taihou]] is '''not''' able to use Jet planes despite being an Armored Carrier.)
+
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.
  
−
==Mechanics==
+
=Jet List=
−
Jet planes come with the unique ability to participate in a pre-emptive Aerial Attack phase known as the '''Jet Assault Phase'''. Jets will launch and conduct this per-emptive attack against enemy units, while fighting off enemy jet planes that also participate and attacking enemy units.
+
"Jets" refer to "[[wikipedia:Turbojet|Turbojet]] propelled planes".
  
−
During this phase, the Jet planes are less likely to be taken down by enemy Anti-Air attacks. Keep in mind, however, that they are not completely immune to Anti-Air attacks and can possibly result in planes being lost while in this phase. It is also not currently known if the Jet Assault phase is capable of triggering AACI, where applicable.
+
Currently the game includes 4 planes with a turbojet:
 +
*{{JetFighterBomber2}} {{Equipment/Link|Kikka Kai}}, a "turbojet carrier-based fighter-bomber",
 +
*{{JetFighterBomber1}} {{Equipment/Link|Jet Keiun Kai}}, a "turbojet carrier-based fighter-bomber",
 +
*{{LB Fighter Jet}} {{Equipment/Link|Me 262 A-1a/R1}}, a "turbojet land-based fighter/interceptor",
 +
**So far it just behaves as a regular [[Interceptor]],
 +
*{{Fighter}} {{Equipment/Link|FR-1 Fireball}}, a mixed "piston engine propeller and turbojet carrier-based fighter",
 +
**So far it is just a regular [[Fighter]].
  
−
Once the Jet Assault Phase is complete, the Jet Planes will assist in the main Aerial Attack phase (or after [[LBAS]] takes place), and participate with all other planes to conduct a second attack against enemy units. Jet planes are more susceptible to attack from all other fighters and fleet Anti-Air attacks during this phase.  
+
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 [[Rocket|here]].
  
−
Furthermore, for every sortie you use Jet planes in, '''Steel will be consumed upon use.'''
+
=Mechanics=
 +
1. Two "jets" are currently available in the game, the {{Equipment/Link|Kikka Kai}} and the {{Equipment/Link|Jet Keiun Kai}}.
 +
*Carrier jets have unique equipment icons : {{JetFighterBomber2}} and {{JetFighterBomber1}} respectively
  
−
There are two known '''Jet Assault Phases''' which have been proven to exist at the time:<br>
+
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.
−
*'''Fleet Based Jet Assault Phase'''<br>
 
−
*'''Land-Based Air Squadron Jet Assault Phase'''
 
  
−
===Fleet Based Jet Assault Phase===
+
3. Using jets will consume steel{{steel}} in addition to bauxite{{bauxite}}.
−
When [[Shoukaku|Shoukaku Kai Ni A]] and [[Zuikaku|Zuikaku Kai Ni A]] are armed with a Jet plane and take part in a sortie, the Jet plane will be used before the main Aerial Phase takes place. The above mechanics regarding how Jet Planes attack will occur during this phase.  
 
  
−
Following this, they will take part in the shelling phase in the same way all planes do during this phase when the Armored Carriers attack.
+
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.  
  
−
The Steel that is consumed is dependent on how many Jet planes you have in your carrier that are still available at the start each node battle, and the type of Jet plane that is used. Steel will be consumed for each node where the Jet planes take part in the Jet Assault Phase.
+
5. Unlike most planes, both jets are '''Long [[Range]]''' {{Range}}.
  
−
===Land-Based Air Squadron Jet Assault Phase===
+
6. Jets have a high [[AAR|Anti-Air Resistance]] that reduces losses to anti-air fire.
−
When a Jet is equipped to your [[Land-Based Air Squadron]], the Jet plane will take part in a '''Jet Assault Phase''' before the Land Based Air Squadron conducts their main attack. They will perform the '''Jet Assault Phase''' in the same way as mentioned above and then follow up with taking part in the Land Based Air Support Phase.
 
  
−
Steel consumption is is dependent on how many Jet planes are in your [[LBAS]] slot at the time. It will be consumed for each node where Land Based Air Support is used, and also during Enemy Air Raids, if the Jet is set to perform Air Defense.

===Steel Consumption===
+
7. Jets will go through '''three''' different shoot-down phases per normal battle.
−
Steel is used for Jet plane equipment to help maintain the engines and will be consumed for each node Jet planes are involved in: Nodes where [[LBAS]] are used, when Armored Carriers [[Shoukaku|Shoukaku Kai Ni A]] and [[Zuikaku|Zuikaku Kai Ni A]] are equipped with Jets and deployed to battles, or during Enemy Air Raids when a Jet is equipped in your [[LBAS]] and attempting to intercept.
+
* Anti-air during the Jet Assault.
 +
* Shoot down during Air Control.
 +
* Anti-air during the normal airstrike.
 +
The jet assault phase cannot trigger [[AACI]].
  
−
As mentioned above, the steel you consume is dependent on the number of Jets available on each slot, the number of nodes they participate in, and/or the number of times they attempt to intercept an Enemy Air Raid. In addition, the type of Jet you use will also vary in terms of steel consumed as well.  
+
8. Jets '''do not count''' as [[Dive Bomber]]s nor [[Fighter]]s, and so cannot activate the [[CVCI]] or take part in it.
  
−
The following table illustrates the steel consumption rate for each plane:
+

+
|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.
 +
}}
  
−
Using this as an example we can determine a basic idea of how the Jet planes work.  
+
==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 [[AAR|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.
  
−
For example, if [[Shoukaku|Shoukaku Kai Ni A]] is armed with a [[Kikka Kai]] in her 34 slot and participates in a sortie. During the first node, she will use all 34 of her planes, and will consume steel for all 34 of the Jet planes (which totals up to 88.4 steel.). She loses 4 planes during the Aerial phase in the first node, and then proceeds to the next node in which she uses the 30 planes she has left (which will consume 78 steel). She now loses 6 planes during the Jet Assault Phase, and then 4 more during the Aerial phase for this node, resulting in her having 20 planes left. In the final node, she uses the 20 planes remaining, which results in 52 steel being consumed.

Jet Keiun Kai will involve more extensive effort as you'll need to have a [[Prototype Keiun]], a large amount of resources (especially steel and Bauxite) along with a large amount of screws, at least 6 [[Ryuusei]], 4 [[Reppuu]], and a Ne-Type Engine. You will need to improve the [[Prototype Keiun]] to its maximum level via [[Akashi's Improvement Arsenal]], and then upgrade it into a [[Jet Keiun Kai]].

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:

  • JetFighterBomber2.png Kikka KaiKikka Kai, a "turbojet carrier-based fighter-bomber",
  • JetFighterBomber1.png Jet Keiun KaiJet Keiun Kai, a "turbojet carrier-based fighter-bomber",
  • Land-based Fighter Jet Me 262 A-1a/R1Me 262 A-1a/R1, a "turbojet land-based fighter/interceptor",
  • Fighter FR-1 FireballFR-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 KaiKikka Kai and the Jet Keiun KaiJet Keiun Kai.

  • Carrier jets have unique equipment icons : JetFighterBomber2.png and JetFighterBomber1.png respectively

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

3. Using jets will consume steelSteel in addition to bauxiteBauxite.

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 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
JetFighterBomber1.pngJet Keiun KaiJet Keiun Kai 0.6 0.5 0.7
JetFighterBomber2.pngKikka KaiKikka 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{Count}_\text{Plane} \times \text{Steel Cost} \rceil }[/math]
With
  • [math]\displaystyle{ \text{Count}_\text{Plane} }[/math] is the current plane count at the start of the battle.
  • [math]\displaystyle{ \text{Steel Cost} }[/math] is the steel cost per plane.
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 Anti-Air and Dive Bombing Dive Bomber Attack in-game, and among the only planes to provide Range 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
