Map details

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 

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 slowly
• Boss health will stop regenerating once the bar is fully depleted. It must be killed one more time to win.
• 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:
  • 「CAx1 DDx1 BBx1 CVx2」 and one additional ship (wildcard).
  • 「CVLx1 CVx2 BBx1 CLTx2」
  • 「CAVx1 DDx1 BBx2 CVx2」
  • 「CLx1 BBx1 CVx2 CAx2」
  • 「BBAVx1 BBx1 CVx2 CLTx1 DDx1」

Tips

• ​Recommended Formation:
  • ​If your fleet has high AA, line abreast on node C&D (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.
