General Guidelines

E-1 is a 2.5 Phase Single-Fleet Map consisting of a Transport, Unlock and TP Phase. It is also possible to farm fuel in large quantities on this map. See the collapsible guide below for more information.

Fuel Farming

Guide to Fuel Farming on E1

Node E is a resource Node on this map that can be farmed for fuel. Its maximum reward of 200 Fuel is calculated as:

[math]\displaystyle{ \text{Fuel}= \text{min}\begin{cases} 20 + 15\times\text{N}_\text{Drum} + 20 \times\text{N}_\text{DLC} \\ 200 \end{cases} }[/math]

The Ships required for the shortest routing (Start-C-E) are 1AO 4DD, the remaining slot can be filled by a CV(L)/SS(V). In case of AV/CV(L) they should be set up with a full bombing setup as the opening airstrike is not affected by Morale. The single Combat Node is C, containing a light enemy Torpedo Squadron.

Notes:

You can advance even after a ship in your fleet was heavily damaged (大破) and put into taiha-state at Node C as the following Resource Node is not a combat node. Doublecheck your fleets status before reentering the map
Fodder use and zero morale farming is possible
Kamoi is the recommended pick for AO as Hayasui is more expensive to sortie. Kamoi Kai is not a AO, but an AV.
If you havent started the Event yet, you can farm fuel on Casual difficulty to make the combat node easier
Be aware that locks still get applied to ships you use to farm fuel here, so plan accordingly if you plan to clear maps on higher difficulties

"I dont have a Fleet Oiler, what are my options?"

A Fast+ Fleet without DDs routes C-E as well.

While not recommended it is also possible to get to the Fuel Node with a slow fleet consisting of AV CVL 4DD, but it takes the additional combat Node B, greatly impacting efficiency due to lower speed, higher cost and retreat rates.

Phase 1: Defeat Mediterranean CL Princess

The goal of this phase is to deplete the HP Bar and defeat the CL Princess found at Node J. Aside from a Nu Class Flagship Kai Light Carrier in some compositions her escorts are not a threat. Only she herself with 740HP and up to 228 Armour on Hard Mode can be considered troublesome. One to three historical ships to deal with her are recommended.

Recommended Fleet: 1FBB 1CA 1CL 1CV 2DD (Fast Fleet)
Route: C F H J
LBAS: Range 6, 100/225 Airpower for AP/AS
Additional Notes: Vanguard Formation can be utilized to help with preboss Nodes. Support Expeditions are not needed

Phase 1.5: Unlock the TP Node

This is not required on lower difficulties. On Hard Mode, you need to A+-Rank Node D consisting of up to 3 Supply Depot Hime, 1-2 Artillery Imps and 2 PT Imps. Set up your Ships with the according equipment to deal with them as outlined here. PT Imps are weak to AA Guns + Skilled Lookouts on your DDs.

Recommended Fleet: 1FBB 1CA 1CL 1CVL 2DD (Slow Fleet)
Route: B D
LBAS: Range 3, 136 Airpower for AP
Additional Notes: Support Expeditions are not needed but node support can be used to deal with PT Imps

Phase 2: Deplete the TP Gauge

The Goal of this Phase is to deplete the TP Gauge. The TP boss can consist of (French BB Hime) and a weaker variant of the Mediterranean CL Hime accompanied by some elite DDs. To deplete the Gauge faster, it is recommended to take Transport Equipment like Drums and Daihatsu-Class landing craft on your weak surface combatants. AACI for the preboss Air Raid is recommended.

Recommended Fleet: 1FBB 1CV 4DD
Route: C F G N O
LBAS: Range 7, 101 Airpower for AS (108 LD)
Additional Notes: It might be preferable to gun for A-Ranks here as French BB Hime still has relatively high Armour, at 256. Support Expeditions are not needed unless going for S ranks. If only a few Points are remaining you can start replacing Transport Equipment for Combat Equipment.
