Tips

This map is the first one to have an enemy battleship, which will enforce a second shelling phase during the day battle.

  • It is important to bring strong enough ships to defeat this BB flagship.

This map is also great for farming fuel.

Fleet Notes
When using an AO, the reach rate is 100 %, but is only 80 % when using an AV instead.
  • Once the first battle is complete, "retreat" and "resupply" before going back out.

As many   Landing Craft and   Amphibious Tanks  should be equipped as possible to maximize fuel gain (+3 per craft).

  •   Drums  works as an inferior substitute (+2 per drum).
  • Using the aforementioned equipment in the fleet is necessary to outweigh the resource cost of the fleet.
  • If lacking enough Amphibious Tanks for SS(V), Drum-capable SS are recommended as a substitute.

Notes:
  1. ↑ If the total value has a decimal, only the rounded-down value is applied.

If done correctly, this can result in an outstanding fuel gain that surpasses expedition gains.

  • Using "cheap" ships to refuel in the fleet (such as Kamikaze-class and Mutsuki-class) will optimize fuel consumption/farming.
  • Alternatively, it is possible to use throwaway DDs with Drums that are never refueled until they are critically damaged, and then scraped to save on resources (do not forget to swap their drums with the new ones before doing this).
