==Historical Bonuses==
{{/Historical Bonuses}}

==Map Overview==
E-6 consists of 4 main phases and requires the use of Single Fleets, Striking Forces, and Combined Fleets.

* This map uses 4 to 6 locks:
** [[File:{{ROOTPAGENAME}} Tag 2.png]] '''2nd Torpedo Squadron''' (from E-2, E-3, & E-5),
** [[File:{{ROOTPAGENAME}} Tag 3.png]] '''Supporting Combined Fleet''' (from E-2),
** [[File:{{ROOTPAGENAME}} Tag 4.png]] '''Combined Fleet''' (from E-3),
** [[File:{{ROOTPAGENAME}} Tag 6.png]] '''Operation I-go Fleet''' (from E-4 & E-5),
** [[File:{{ROOTPAGENAME}} Tag 7.png]] '''Counter Landing Force''' 
** [[File:{{ROOTPAGENAME}} Tag 8.png]] '''Decisive Combined Fleet'''
** {{TextGlow|'''Some tags can be mixed in all difficulties'''|black|text-colour=Lime|glow-size=2px}}, see ''[[#Branching Table|here]]''.

* Initially, no LBAS is available to be sortied to this map,
** Clearing Phase 2 allows 1 Land Base to be sortied,
** Unlocking Phase 3 allows 2 Land Bases to be sortied and 1 to defend,
** Clearing Phase 3 allows 3 Land Bases to be sortied.
* '''[[Early Spring 2023 Event#New Mechanics|"Airstrike Supported Battle" nodes]]''' are present on {{MapRoute|B|darkorange|Y2|darkorange}}
* '''"Night Battle" nodes''' are present on {{MapRoute|H2|purple|T|purple}}
* '''"Enemy Ambush" node''' is present on {{MapRoute|S|orange}}

==Phase 1==

* Striking Force: '''"1FBB, 1FBB/CV, 0-1CVL/CAV/CLT, 1CL, 3DD"''' [[File:{{ROOTPAGENAME}} Tag 6.png|30px]]
* Route: {{MapRoute|1||A|red|C|red|E|red|G|red}}
** This fleet can utilize a [[Special Attacks#Kongou-class Touch|''Kongou''-class Touch]].

==Phase 2 - TP==
Phase 2 is a '''"[[Transport Operation]]"''':

* TCF: '''"1LHA/CL/AV, 1AV, 4DD + 1-2CAV, 1-2CL, 3-4DD "''' [[File:{{ROOTPAGENAME}} Tag 7.png|30px]]
* Route: {{MapRoute|2||H|pink|H2|purple|J|pink|K|darkorange|M|green|O|red}}
** LoS check: 75 Cn3 (Hard)
** A [[CVE]] can be used instead of the LHA/CL/AV, adding an extra node ({{MapRoute|L|red}}).

==Phase 2.5 - Gimmick==
{|class="wikitable" 
!       !! U
|-
|Hard  ||S x3
|-
|Medium ||S x2
|-
|Easy  ||A+ x2
|-
|Casual||A+ 
|}

*Use [[#Phase 3]]'s fleet

==Phase 3==
* Strinking Force: '''"1CAV, 1CL, 5DD"''' (Fast) [[File:{{ROOTPAGENAME}} Tag 2.png|30px]]
* Locking Notes: Forced Ship Locking wherein all ships must be the E2 Yellow Tag (used in E2) to start on western side. '''APPLIES ON ALL DIFFICULTY'''
** If any other tagged ship is on the fleet you will automatically start on the east side of the map.
* Route: {{MapRoute|3||Q|red|R|pink|T|purple|V|red|X|red}}
* LBAS: Range 1, AP/AS ??/??
** At least 5/3/2/1 (H/M/E/C) ships need to be equipped with {{Surface Radar}} [[Surface Radar]]s to avoid the '''"Enemy Ambush" node''' on {{MapRoute|S|orange}}.
** The use of the {{IconText|{{FCF}}|SFFCF}} {{Equipment/Link|Striking Force Fleet Command Facility}} (SFFCF) is recommended
** The boss is an '''[[Installation]]''' and requires appropriate gear to be defeated,
*** She is especially weak to "Nuke" setups 
** The boss fleet includes one or two [[PT Imp Pack]]s, requiring appropriate gear to be defeated (these can be ignored as S-rank is optional):
{{Anti-PT Imp Setups}}

==Phase 3.5 - Gimmick: Unlocking the shortcut==
The following steps have to be performed to unlock the Shortcut (can be done right from the start of P4):

{|class="wikitable" 
!      !! G !! Z1 !! LBAS
|-
|Hard  || S x2|| AS|| ASx2
|-
|Medium|| A+ x2|| AS|| ASx2
|-
|Easy  || A+ x2|| -|| AS
|-
|Casual|| A+ x2|| -|| -
|}

<tabber>
|-|Node G=
*Use [[#Phase 1]]'s fleet
** AV no longer allowed due to Branching Rules at Phase 2+

|-|Node Z1=
*Use [[#Phase 4]]'s fleet
*AP/AS: 321/722 (Hard)

|-|LBAS=
*AP/AS: 284/638 (Hard)
</tabber>

==Phase 4==
<tabber>
|-|STF=
* STF: '''"2FBB, 1CV, 2CA, 1CL + 0-1CLT, 1CL, 3DD, 1-2SS"''' (Fast) [[File:{{ROOTPAGENAME}} Tag 3.png|30px]][[File:{{ROOTPAGENAME}} Tag 4.png|30px]][[File:{{ROOTPAGENAME}} Tag 8.png|30px]]
* Route: {{MapRoute|4||R|pink|Y|red|Z|red|Z2|red}}

|-|CTF=
* CTF: '''"2FBB, 2CV, 2CA + 0-1CVL, 1CL, 3DD, 1-2SS"''' (Fast) [[File:{{ROOTPAGENAME}} Tag 3.png|30px]][[File:{{ROOTPAGENAME}} Tag 4.png|30px]][[File:{{ROOTPAGENAME}} Tag 8.png|30px]]
* Route: {{MapRoute|4||R|pink|Y|red|Y1|red|Z|red|Z2|red}}
** This fleet is not recommended due to the preboss

|-|STF Heavy=
* STF: '''"4(F)BB(V), 1CV, 0-1CL, 0-1AS + 0-1AS, 0-1CVL/CLT, 1CL, 2DD, 2SS"''' [[File:{{ROOTPAGENAME}} Tag 3.png|30px]][[File:{{ROOTPAGENAME}} Tag 4.png|30px]][[File:{{ROOTPAGENAME}} Tag 8.png|30px]]
* Route: {{MapRoute|4||Q|red|R|pink|Y|red|Y1|red|Z|red|Z1|pink|Z2|red}}
**The strongest fleet, bringing very high firepower as well as air power.
**One [[AS]] is required for this routing, being either:
***The escort fleet's flagship, rendering it retreat-proof,
***Alternatively in the main fleet, allowing to bring a stronger ship for the night battle. 
**The BB should be both the {{Class|Yamato|Kai Ni}} and  the {{Class|Ise|Kai Ni}}, to bring the strongest Touch and great air power.

</tabber>

* LBAS: Range 4, 168/335 AD/AP (Hard)
* A minimum of 2CA (not CAV), 2CL (for STF), and 3DD is needed to take the shortest path.
** A fast fleet with 2 {{Class|Yamato}} would additionally take {{MapRoute|Y1|red}}.
** The {{Ship/Link|I-201|I-203|text=''I-201''-class|link_category=I-201 Class}} have outstanding historical bonuses in this situation.
** 6/4/3/2 [[Surface Radar]]s are required to route to {{MapRoute|Y|red}} on (H/M/E/C).

==Debuff==
Once LD has been reached, the following steps have to be performed to debuff the boss:

{|class="wikitable" 
!      !! G !! O!! L!! X !! Z1!! LBAS
|-
|Hard  || S|| S|| S|| S|| AS|| AS x2
|-
|Medium|| S|| S|| -|| S|| -|| AS
|-
|Easy  || A+|| A+|| -|| A+|| -|| AS
|-
|Casual|| A+|| A+|| -|| -|| -|| ?
|}

<tabber>
|-|Node G=
*Use [[#Phase 1]]'s fleet
** AV no longer allowed due to Branching Rules at Phase 2+

|-|Node O=
*Use [[#Phase 2 - TP]]'s fleet
**Can be done at the same time as node {{MapRoute|L|red}}

|-|Node L=
*Use [[#Phase 2 - TP]]'s fleet with '''1[[CVE]]'''.
**Can be done at the same time as node {{MapRoute|O|red}}

|-|Node X=
*Use [[#Phase 3]]'s fleet

|-|Node Z1=
*Use [[#Phase 3.5 - Gimmick: Unlocking the shortcut]]'s fleet

|-|LBAS AS=
*This step can be accomplished by sending 1 SS(V) until the Air Raid is triggered.
*''Numbers may be different due to the presence of unknown elements''
{|class="wikitable" 
!      !! AP!! AS
|-
|Hard  || 281|| 632
|-
|Medium|| 262|| 588
|-
|Easy  || 251|| 564
|-
|Casual|| 91|| 204
|}
</tabber>


Once Debuff is complete the CG will change to the following:
