==Ship Bonuses==
{{:{{ROOTPAGENAME}}/E-1/Historical_Ships}}

==Map overview==
E1 is a single-fleet three-phase map consisting of one two-part unlocking Phase and one Boss Phase. 
* No [[LBAS]] is available to sortie.
* This map utilizes [[File:{{ROOTPAGENAME}} Tag 1.png]] '''R-Area Defense Unit''' lock.

==Phase 1: Unlocking the Route to Rabaul==
In this phase, there are three requirements to unlock the path to Rabaul :
*Reach Node {{MapRoute|E|blue}}
*Reach Node {{MapRoute|K|blue}}
*S rank Node {{MapRoute|J|red}}

<tabber>
|-|Node E=
* '''1SS'''
* Route: {{MapRoute|A|blue|B|red|C|pink|D|red|E|blue}}
** Only {{MapRoute|D|red}} is capable of damaging the submarine, but as it is right in front of an empty end node the submarine can be equipped with a {{EmergencyRepair}} {{Equipment/Link|Emergency Repair Personnel|Emergency Repair Goddess|text=Damage control|link_category=Repair Personnel}} and continue the sortie after {{MapRoute|D|red}} without consuming said item.

|-|Node K=
* '''1SS'''
* Route: {{MapRoute|A|blue|F|red|G|pink|H|pink|I|red|K|blue}}
** Only {{MapRoute|I|red}} is capable of damaging the submarine, but as it is right in front of an empty end node the submarine can be equipped with a {{EmergencyRepair}} {{Equipment/Link|Emergency Repair Personnel|Emergency Repair Goddess|text=Damage control|link_category=Repair Personnel}} and continue the sortie after {{MapRoute|I|red}} without consuming said item.

|-|Node J=
* '''1FBB, 1CVL, 0-1CL, 3-4DD'''
* Route: {{MapRoute|A|Blue|F|Red|H|pink|J|red}}
** {{MapRoute|J|red}} contains a light torpedo squadron.
** Setting up the fleet with AA and ASW to deal with Nodes {{MapRoute|F|red}} and {{MapRoute|J|pink}} is recommended.
</tabber>

==Phase 2: Making contact with Rabaul Base==
This phase requires the fleet to attempt to reach Rabaul base on Node {{MapRoute|M|grey}}. '''3 visits''' are required to complete this phase on all difficulties.

* '''1FBB, 1CVL, 0-1CL, 3-4DD'''
* Route: {{MapRoute|A|Blue|F|Red|H|pink|J|red|L|red|M|grey}}
** Setting up the fleet with AA and ASW to deal with Nodes {{MapRoute|F|red}}, {{MapRoute|J|pink}} and {{MapRoute|L|red}} is recommended.

==Phase 3: Defeating the Heavy Cruiser Princess==
The Boss Node {{MapRoute|R|red}} features a Heavy Cruiser Princess accompanied by up to two submarines.

<tabber>
Vanguard Formation Fleet=
* '''1FBB, 1CVL, 1CL, 3DD'''
* Route: {{MapRoute|F|red|H|pink|J|red|L|red|N|pink|O|red|Q|blue|R|red}}
** Using a fast fleet with 4DD skips {{MapRoute|L|red}}.
** Since the enemy fleet also contains submarines, it is recommended to set up the fleet for Vanguard Formation with ASW Elements in the upper half of the fleet and utilize that formation at the boss (for example: CL/DD, DD, CVL, FBB, DD, DD).
** Boss Support is not recommended due to Vanguard Formation nerfing its damage.
** It is recommended to set up one ship with TCI and/or other high damage Yasen Attacks

|-|Echelon Formation Fleet=
* '''2BB, 1CVL, 3DD'''
* Route: {{MapRoute|F|red|H|pink|J|red|L|red|N|pink|O|red|Q|blue|R|red}}
** 2+ [[OASW]] ships are highly recommended
** It is possible to use Nagato/Mutsu [[Special Attack]] here
*** The E1 Tag can be sortied to E3P3, therefore it is possible to use the ships planned for that phase here already
** Boss support is recommended, but not mandatory (especially when using Nagato/Mutsu Touch)
</tabber>
* There is an LoS check at {{MapRoute|O|red}} Cn3:.
** Cas = 31, Easy = 31, Med = 38, Hard = 48.
* [[AACI]] for the 2 air nodes on Route is highly recommended.
