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

==Map Overview==
E4 is a single/Striking Force/Combined fleet three-phase map consisting of one transport and two boss phases. 
* 2 [[LBAS]] are available on this map:
** Initially, only 1 can be set on '''Sortie''', the other being limited to '''Defense''',
** After Phase 1, both can be set on '''Sortie'''.

*This map uses 3 locks:
** [[File:{{ROOTPAGENAME}} Tag 4.png]] '''1st Torpedo Squadron''' (from on E-3),
** [[File:{{ROOTPAGENAME}} Tag 5.png]] '''5th Fleet Main Force''' (from on E-3),
** [[File:{{ROOTPAGENAME}} Tag 6.png]] '''1st Fleet''' (reused on E-7).

* '''[[Node|"Airstrike Supported Battle" nodes]]''' are present on {{MapRoute|A1|darkorange|C|darkorange|R1|darkorange}}

==Phase 1 - TP==
Phase 1 is a '''"[[Transport Operation]]"''':

<tabber>
|-|Single =
* Single Fleet: '''0-1(F)BB(V), 0-1AV/CVL, 0-1CL, 4-5DD''' [[File:{{ROOTPAGENAME}} Tag 4.png|30px]]
* Route: {{MapRoute|1||A|red|B|red|C1|pink|C2|red|D|green|F|red}}
|-|SF=
* [[Striking Force Fleet]]: '''0-1AV/CVL/CAV, 0-1BBV, 1CL, 4-5DD''' [[File:{{ROOTPAGENAME}} Tag 4.png|30px]]
* Route: {{MapRoute|1||A|red|A2|pink|B|red|C1|pink|C2|red|D|green|F|red}}
</tabber>
*LBAS range: 5
** Bringing an [[AACI]] capable ship is recommended to pass through the air node.
** Bringing ASW power is required against the boss.
***The CVL here should be a [[CVE]].
**It is possible to bring an (F)BB(V) to gain the second shelling, but this might not be needed.
*** Must be '''FAST''' if a (F)BB(V) is used.

==Phase 2 - Boss==
<tabber>

|-|4CV=
* CTF: '''4CV(B), 2CAV + 1CL, 0-2CA/CLT, 3-5DD''' [[File:{{ROOTPAGENAME}} Tag 6.png|30px]]
**A fleet mainly focusing on air power.

|-|2BB & 3CV=
* CTF: '''2(F)BB(V), 2-3CV(B), 1-2CAV/CL + 1CL, 0-2CA/CLT, 3-5DD''' [[File:{{ROOTPAGENAME}} Tag 6.png|30px]]
**A fleet mixing CV for air power, and 2BB that should utilize a [[Special Attack]]

|-|Night FBB=
* CTF: '''3CV(B), 1CVL, 1CAV, 1CL + 2FBB, 1CLT, 1CL, 2DD''' [[File:{{ROOTPAGENAME}} Tag 6.png|30px]]
**A fleet mixing CV for air power, and 2FBB in the escort that should utilize a [[Special Attack#Kongou-class Touch|''Kongou''-class Touch]]

|-|1BB & 4CV=
* CTF: '''1(F)BB(V), 4CV(B), 1CL + 1CL, 0-2CA/CLT, 3-5DD''' [[File:{{ROOTPAGENAME}} Tag 6.png|30px]]
**This fleet brings 4 CV, and the BB's second shelling
</tabber>

* Route: {{MapRoute|2||G|blue|I|red|J|red|M|red|N|pink|Q|red}}
* LBAS range: 8
*LoS check: ?
*AP/AS: 302/678 Hard
**If the CTF is Slow, then a second CL is required to route {{MapRoute|J|red|M|red}}.  Fast CTFs need only the 1CL in the escort fleet.
** Bringing an [[AACI]] capable ship is recommended to pass through the air node and against the boss.

==Phase 2.3 - Unlock the Boss Node==
Once phase 2 cleared, the following steps have to be performed to unlock the {{MapRoute|Q|red}} Boss:
{|class="wikitable" 
! !! T!! U
|-
| Hard|| S x2|| A+ x3
|-
| Medium|| S x2|| A+ x2
|-
| Easy|| ?|| ?
|-
| Casual|| ?|| ?
|}

It is possible to clear both requirements in one run.
<tabber>
|-|Node T=
* Refer to [[#Phase 3 - Boss]]'s '''Striking Force''' fleet for composition and routing.
*LBAS range: 7
{{color|red|Using a combined fleet will off route to the 2nd starting point.}}

|-|Node U=
* Refer to [[#Phase 3 - Boss]]'s '''Striking Force''' fleet for composition and routing.
*LBAS range: 6
{{color|red|Using a combined fleet will off route to the 2nd starting point.}}
</tabber>

==Phase 2.7 - Unlock the Shortcuts==
Once the {{MapRoute|X|red}} Boss unlocked, the following steps have to be performed to unlock the shortcuts:
{|class="wikitable" 
! !! F!! Q!! M3
|-
| Hard|| S|| S|| S
|-
| Medium|| S|| S|| A+
|-
| Easy|| S|| S|| A+
|-
| Casual|| ?|| ?|| ?
|}

<tabber>
|-|Node F=
* Refer to [[#Phase 1 - TP]]'s fleet for composition and routing.

|-|Node Q=
* Refer to [[#Phase 2 - Boss]]'s fleet for composition and routing.

|-|Node M3=
The following need to be completed to reach node {{MapRoute|M3|red}}:
#Assemble a CTF with 11 ships "FAST+" '''AND''' 1 ship "SLOW",
#*Equip the flagship with the {{IconText|{{CommandFacility}}|FCF}} [[FCF]],
#*It is possible to not use any FCF, and just let the SLOW ship sink,
#*The SLOW ship should be "heavily damaged" (taiha), with 1 {{EmergencyRepair}} {{EquipmentLink|Emergency Repair Personnel|Emergency Repair Goddess|text=Repair Personnel|link_category=Repair Personnel}},
#After reaching node {{MapRoute|C|darkorange}}, evacuate the SLOW ship on either {{MapRoute|C|darkorange}} or {{MapRoute|K|pink}},
#*The fleet is the FAST+ and can route to {{MapRoute|M3|red}}

A possible fleet can then be:
* CTF: '''"[[#Phase 2 - Boss]]'s fleet" at "FAST+" with 1SS(V)''' [[File:{{ROOTPAGENAME}} Tag 6.png|30px]]
* Route: {{MapRoute|2||G|blue|H|pink|C|darkorange|K|pink|M1|blue|M2|blue|M3|red}}
**See [[Speed|here]] for more details on how to achieve FAST+.

;Trivia
This special gimmick a a reference to a real event, where a slow ship was left alone to maintain the high-speed pursuit of USS Tautog during this map's battle.
</tabber>

==Phase 3 - Boss==
<tabber>
|-|STF=
* STF: '''3(F)BB(V), 2CVL, 1CA(V)/CL + 1CL, 1-2CA/CLT, 3-4DD (FAST)''' [[File:{{ROOTPAGENAME}} Tag 5.png|30px]]
* Route: {{MapRoute|3||R|blue|S|pink|T|red|V|red|X|red}}

|-|SF=
* [[Striking Force Fleet]]: '''0-2(F)BB(V), 1CVL, 1CAV/CL, 3-5DD (FAST)''' [[File:{{ROOTPAGENAME}} Tag 5.png|30px]]
* [[Striking Force Fleet]]: '''0-1FBB, 1CVL, 1CAV/CLT, 1CL, 3-4DD (FAST)''' [[File:{{ROOTPAGENAME}} Tag 5.png|30px]]
* [[Striking Force Fleet]]: '''1CL, 6DD (FAST)''' [[File:{{ROOTPAGENAME}} Tag 5.png|30px]]
* Route: {{MapRoute|3||R|blue|S|pink|T|red|U|red|V|red|X|red}}
**Those fleets are only advised for gimmicks clearing
**This is the routing '''before''' the shortcut is unlocked.
</tabber>

*If the [[#Phase 2.7 - Unlock the Shortcuts]] is not cleared yet, the routing might be a bit longer.
* LBAS range: 5
*LoS check: ?
*AP/AS: 101/225 Hard
** Bringing an [[AACI]] capable ship is recommended to pass through the air node and against the boss.
**Using a {{Smoke}} '''[[Smoke]]''' on node {{MapRoute|V|red}} can help in surviving it.
*Using any CTF or TCF will off route on starting point 2.

==Phase 3.5 - Debuff==
Once LD has been reached, the following steps have to be performed to debuff the boss

{|class="wikitable" 
! !! F!! Q!! U!! V!! M3!! LBAS
|-
| Hard|| S|| A+|| S|| S|| S|| AS
|-
| Medium|| ?|| ?|| ?|| ?|| ?|| ?
|-
| Easy|| ?|| ?|| ?|| ?|| ?|| ?
|-

|}

<tabber>
|-|Node F=
* Refer to [[#Phase 1 - TP]]'s fleet for composition and routing.

|-|Node Q=
* Refer to [[#Phase 2 - Boss]]'s fleet for composition and routing.

|-|Node U=
* Refer to [[#Phase 3 - Boss]]'s fleet for composition and routing.
* Lighter fleets better route to U.
*LBAS range: 6

|-|Node V=
* Refer to [[#Phase 3 - Boss]]'s fleet for composition and routing.
*LBAS range: 6

|-|Node M3=
* Refer to [[#Phase 2.7 - Unlock the Shortcuts]]'s fleet for composition and routing.

|-|Node LBAS=
{|class="wikitable"

|-
|Hard  || 498
|-
|Medium|| ?
|-
|Easy  || 343
|-
|Casual|| 254
|}
</tabber>

Once Debuff is complete the CG will change to the following:
{|class="wikitable"
![[Abyssal Kushiro Cloud Princess]]
|-
|<gallery>
