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

==Map overview==
E3 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, no LBAS is available,
** After Phase 1, only 1 can be set on '''Sortie''', the other being limited to '''Defense''',


*This map uses 3 locks:
** [[File:{{ROOTPAGENAME}} Tag 1.png]] '''2nd Fleet''' (from E-1, reused on E-7),
** [[File:{{ROOTPAGENAME}} Tag 4.png]] '''1st Torpedo Squadron''' (reused on E-4),
** [[File:{{ROOTPAGENAME}} Tag 5.png]] '''5th Fleet Main Force''' (reused on E-4).

* '''[[Node|"Airstrike Supported Battle" node]]''' is present on {{MapRoute|C1|darkorange|G|darkorange|P|darkorange}}

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

* Single Fleet: '''0-1AV, 0-1BBV, 0-1CVL, 1CL, 3-5DD''' [[File:{{ROOTPAGENAME}} Tag 4.png|30px]]
* Route: {{MapRoute|1||A|red|A1|pink|B|blue|B1|pink|B2|red|C2|green|E|red}}
** Bringing an [[AACI]] capable ship is recommended to pass through the air node.
** Bringing some ASW power can be helpful against node {{MapRoute|A|red}}.
** Both [[Node Support]] & [[Boss Support]] can be utilized to consistently reaches the boss and A-rank.

==Phase 2 - Boss==
<Tabber>
|-|Light Fleet=
* [[Striking Force Fleet]]: '''1CVL, 0-1CAV/CLT, 1-2CL, 3-5DD''' [[File:{{ROOTPAGENAME}} Tag 5.png|30px]]
* Route: {{MapRoute|2||F|blue|H|pink|I|red|L|red|M|red}}
* It is possible to bring an (F)BB(V) to gain the second shelling, but this might not be needed.
* If the fleet is '''SLOW''', fleet requires 4 DD/DE to route
** Otherwise, only 3 DD minimum is needed for a '''FAST''' Fleet.
|-|Heavy Fleet=
* [[Striking Force Fleet]]: '''0-2(F)BB(V)/CVL, 0-1CAV/CLT, 0-2CL, 2-5DD''' [[File:{{ROOTPAGENAME}} Tag 5.png|30px]]
* Route: {{MapRoute|2||F|blue|H|pink|I|red|J|red|L|red|M|red}}
* Heavier fleet that ignores speed and can enable the second shelling round
* Encounters an additional submarine node at {{MapRoute|J|red}}
</Tabber>
*LBAS range: 4
** 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]].
** Have an ASW LBAS send to {{MapRoute|M|red}} is recommended to help kill the boss.

==Phase 3 - Boss==
<tabber>
|-|CTF=
* CTF: '''FAST [[File:{{ROOTPAGENAME}} Tag 1.png|30px]]
**Main: '''1(F)BB(V), 2CV(B), 2CVL, 1CL
**Escort: '''1CL, 1CLT, 4DD
* Route: {{MapRoute|3||O|red|Q|pink|R|red|T|red|W|red}}

|-|CTF/STF=
* CTF/STF: '''FAST [[File:{{ROOTPAGENAME}} Tag 1.png|30px]]
**Main: '''2(F)BB(V), 2CVL, 1CA(V), 1CL
**Escort: '''1CL, 1CLT, 4DD'''
* Route: {{MapRoute|3||O|red|Q|pink|R|red|T|red|W|red}}
</tabber>

*LBAS range: 7
*'''AP/AS = 235/527''' on chip. '''AP/AS = 248/557''' on LD
** Bringing an [[AACI]] capable ship is recommended to pass through the air node and against the boss.
** Bringing some ASW power can be helpful against node {{MapRoute|R|red}}
** Fleet must be Fast to route correctly.

==Debuff==
Once LD has been reached, the following steps have to be performed to debuff the boss:
{|class="wikitable" 
! !! E!! M!! K!! U!! LBAS
|-
| Hard|| A+|| A+|| A+|| A+|| AS x2
|-
| Medium||A+ || A+|| -|| ?|| AS x2

<tabber>
|-|Node E=
* Refer to [[#Phase 1 - TP]]'s fleet for composition and routing.
*LBAS range: 2

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

|-|Node K=
* Striking Force: '''[[#Phase 2 - Boss]]'s fleet without CL (SLOW?)''' [[File:{{ROOTPAGENAME}} Tag 5.png|30px]]
* Route: {{MapRoute|2||F|blue|H|pink|I|red|J|red|K|red}}
*Low LoS is needed.
*LBAS range: 4
**LoS must be relatively low to get to node {{MapRoute|K|red}}
** Bringing ASW power is required.

|-|Node U=
* CTF/STF: '''2(F)BB(V), 2CV(L), 1CA(V), 1CL + 1CL, 2CLT/CA, 3DD''' [[File:{{ROOTPAGENAME}} Tag 1.png|30px]]
* Route: {{MapRoute|3||O|red|Q|pink|R|red|T|red|W|red}}
*LBAS range: 6

|-|Node LBAS=

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

==Trivia==
This map involves many references to The Shield of Hachinohe which is the nickname of Inagi:
<div class="mw-collapsible mw-collapsed">

;Phase 3
*Is based on the final engagement and defensive actions of Inagi. Her actions here are what earned her the name 八戸の盾 or The Shield of Hachinohe. The shrine in Hachinohe also commemorates her actions and there is a service for her as well as a memorial dedicated to her in the area. 

;Node W
*Is the final position of Inagi after 2 hours of drawing the attention of the Allied Aircraft. According to Japanese records and American records it was the aircraft from TF 38 USS Essex and USS Randolph that sank her. There is some discrepancy as the English Wikipedia entry states it was HMS Formidable that sank her but Royal Navy Archives state that Formidable sent planes to Shiogama. Meanwhile it was HMS Indefatigable that sent planes to Kesennuma, Kakuda and Hachinohe.
