Map details

Before you embark on E-2 and beyond, please remember that Compass and RNG are NOT on your side. So, keep frosty and don't let frustration overcome you. Too many admirals have sunk their ships or run of resources. Rest, calm down, and plan properly if needed. Don't be one of them.

E-1 - サーモン諸島海域 (Solomon Islands)

E-1

E-1 Map

• Focused on day battle
• Boss health does not regenerate
• Friendly for newer admirals
• Difficulty will be around that of World 2
• Rewards I-19 upon clearing

Tips

• Have at least 1 DD or 1 CL (e.g Isuzu Kai 2) fully equipped with depth charges and sonars. Node B consists of 1-3 submarines only.
• Node B has submarines while node C has light aircraft carriers. Plan accordingly.
• Recommended formation: line abreast on node B and line ahead on all other nodes.

E-2 - ルンバ沖海域 (Lunga Point)

E-2

E-2 Map

• Focused on night battle (start battle at night)
• Boss health does not regenerate
• Friendly for newer admirals
• Rewards CL Noshiro upon clearing
• Day battle condition for node J and K (dead end and boss): enemy elite DD survived 
• Do not get frustrated when you fail to sink the boss continuously. The health does not regenerate.

Branching rules

• B [math]\displaystyle{ \longrightarrow }[/math] E if you have 3+ BB

Tips

• Bring your entire fleet sparkling.
• Use a fleet of DD/CL/CLT/CA and equip them so that they can trigger double-attack. Many players find Double-attack more useful than cut-ins because it almost always guarantees a critical which one-hits most ships, including the boss. See combat on double-attack and cut-ins requirement.
• If you want to conserve resources, use a SS as your flagship and and equip her with 2 turbines. However, reaching the boss is difficult because enemy CL have depth charge/sonar equipped.
• Recommended Formation: line abreast on non-boss nodes and line ahead on boss node. line abreast on boss node can be useful if your ships have barely taken damage and want to reduce the likelihood of destroying the two elite DD.
• Recommended Equipment: Sets of equipment which trigger double-attack with radar/turbine on the remaining slot(s).
• If you end up at E, the ASW formation is ideal for handling the subs waiting there.

E-3 - サンタクロース諸島海域 (Santa Cruz Islands)

E-3

E-3 Map

• Focused on day battle
• Boss health regenerates at a rate of 1.5%/hour and complete boss kill removes 20% of the health bar.
• Boss health will NOT stop regenerating once the bar is fully depleted. It must be killed one more time to win (if you depleted the Boss' health and you did not sink the boss during day, you can try to sink it during night battle and it will clear the stage).
• Only for experienced admirals but new admirals should still try after leveling up and saving up some resource for some time.
• Rewards equipment package (furniture craft item, emergency repair kit, full repair kit, 53cm oxygen torpedo)

Branching rules

• A certain fleet formation is needed in order to reach the boss (or else you'll get sent to node G, H, or I), so far the confirmed ones are:
• 「CVLx1 CVx2 BBx1 CLTx2」
• 「BBVx1 BBx1 CVx2 CLTx2」
• 「BBVx1 BBx1 CVx2 CLTx1 DDx1」
• 「BBVx1 BBx1 CVx2 CAx1 DDx1」
• 「BBVx2 CLTx2 CVx2」
• 「DDx1 BBx1 CLTx2 CVx2」
• Possible alternative branching rules: having at least one CAV or BBV will provide a chance to jump from the north route to the south route, and vice versa.  In addition, at node E, any composition with 2 or more non-aviation battleships goes directly to I.^[1]

Tips

• ​Recommended Formation:
  • ​If your fleet has high AA, line abreast on node C (enemy SS) and line ahead on all other nodes.
  • If your fleet has low AA, use ring formation on node A, E, G, H, and I because there are CV and CVL. Line ahead for boss node J.
• Recommended Equipment:
  • For CV/CVL: air superiority fighter (green) planes for AA. Dive bomber (red) planes are better than torpedo bomber (blue) planes because it deal more damage against BB and CV. A recon (yellow) plane is enough in your fleet, but not really necessary.

E-4 - アイアンボトムサウンド (Ironbottom Sound)

E-4

E-4 Map

• 

  E-4 day battle clear

• 

  E-4 day battle clear

• 

  E-4 night battle clear

• Focused on night battle (start battle at night)
• Boss health regenerates at a rate of 2.1%/hour and complete boss kill removes 17.2% of the health bar.
• Boss health bar will keep regenerating even when the bar has been fully depleted.
• Only for experienced admirals
• Need a flagship sink to clear
• Theme: Night battles and airfield bombardment
• Night battle and the following day battle is considered as ONE battle. So, don't worry if you have heavily damaged ships at night.
• Day battle won't occur if both the second and third ship in the enemy fleet are sunk.
• Type 3 ammo deals bonus damage against Airport Boss (Historical reference to Henderson Airfield). You WILL need it, as most player typically went with four type 3 ammo for the boss battle.
• Rewards I-8 upon clearing.

Branching rules

• C [math]\displaystyle{ \longrightarrow }[/math] F if you have 2 Kongou-class BBs
• D [math]\displaystyle{ \longrightarrow }[/math] G if you have 3+ BB

Tips

• To increase the chances of your ships surviving with enough health, use line abreast on non-boss nodes and line ahead on boss node.
• Recommended equipment:
  • Sets of equipment which trigger double-attack with Type 3 ammo on the remaining slots. If you don't have Type 3 ammo, use turbines/radars to improvise. 
  • For Ooi/Kitakami, equip midget sub on the last slot (even though torpedoes don't hit the boss) in order to kill other enemies if you trigger day fight.
  • For BB, equip each one with 46cm main cannon so they can hit the boss' planes if you trigger day fight.
• If you want to conserve resources or you're running out of resources, a full DD or 4DD 2CLT fleet can be used to deplete the bosses HP to 0. Equip them to trigger double-attack and use line abreast on all nodes and Line Ahead on boss nodes. Note you won't be able to use the shortcut (C -> F) with this fleet setup.
• Stay frosty. The final kill might be hard. Don't take too much risk.

E-5 - サーモン海域最深部 (Ironbottom Sound, Final Stage)

• A [math]\displaystyle{ \longrightarrow }[/math] B If your fleet is either full high-speed or low-speed.
