Tips

Be advised: The Developers have mentioned that the composition and map will change over time, this may even include the resource node possibly. So take advantage of the map while it is possible.

Regarding Land-Based Air Squadrons

See the unlocking steps here: LBAS Unlocking

  • 1 LBAS is available to sortie.
    • Upon completing the quest B175, the LBAS group will be unlocked, which is highly recommended to help simplify the battle on the boss node for this map.
    • It is recommended to bring Land Based Bombers, Land-Based ASW Bombers 
       
      , and Interceptors/Fighters, to increase effectiveness on the Boss.
    • The LBAS range needed to reach the boss is 2, other nodes' range being equal or higher.
  • This map is also the best location to train Land-Based planes to max-proficiency ❱❱ . Bring only planes with a range of at least 3 (7 for furthest nodes) as they will reach submarine Nodes on B, C, J, and K.

Recommended Fleets

This guide will go over the events of this map in sequential order upon unlocking Quest B175. Since this is a normal map, it is not required to complete things in the order mentioned, but it is still recommended to at least complete B175 to unlock the LBAS.

Reach node O for Quest B175

  • 1-6SS(V)
  • Route = C D F J K M O
    • The LoS needed is about 32 (Cn3).
    • Several  Seaplanes or  Submarine Radars 
       
       
       
      might be needed to have enough LoS to route from M to O.
    • Submarines will face little to no threat along the way.

Sink the Hi Convoy Princess P

In this part, it is recommended to use the LBAS to clear the map more easily, as this will give the necessary edge needed to fight against the boss. While the boss is not strong, she is very tanky and is escorted by a fleet that may be troublesome to wipe.

  • 0-1BBV, 1CVL, 1CA/CL, 3-4DD/DE
  • Route = A B E J L P
  • LBAS Node P: Range = 2
    • Allows bringing a strong fleet to the boss.
    • Fleet will go through 2 Submarine Nodes, 1 Air Node, and 2 Surface/Submarine Nodes.
    • Node J can especially be problematic due to it featuring 3 Submarine So-Class Flagship , but will become even more dangerous on Last Dance with the enemy fleet in line ahead formation.
  • It is recommended to bring:
    • Ships that can effectively OASW to survive the submarines.
    • An Ise-class Kai Ni 
       
      and a CVE to help clearing while having AS.
    • An AACI for node E as well as the boss.
    • At least 1 TCI capable DD.
    • If possible, ships that can take on multiple roles.
  • The boss does not have a lot of planes, bringing enough airpower and AACI can effectively deplane her, rendering her defenseless.
  • LBAS should use a combination of Fighter, Bombers, and ASW Bombers to effectively help with clearing the boss.
  • Last Dance comp will buff the DDs and CL in her fleet along with giving her additional airpower.
    • Bring additional airpower as a countermeasure to effectively beat her.

This map has a special routing if you bring Taiyou-class CVE 
 
 
. They can be brought when you use light fleet to get more firepower.

  • 1CT, 1DD / 1 Taiyou-class CVE 
     
     
    , 3DE
  • Route = A B E J P
  • LBAS Node P: Range = 2
    • A cheap but weak fleet.
    • Will go through, 1 Submarine Node, 1 Air Node, and 1 Surface/Submarine Node.
    • Not recommended due to the risks this map presents to fleets with a lack of strong combat-effective ships.
    • Dependent on the DD or CVE to score the kill against the boss.
    • DEs will take on OASW.
    • The CT will mainly do Surface Combat.
    • The DD will do a TCI, CVE should do night carrier cut in attack.
    • Node E and P may be troublesome due to a lack of air defense.
    • LBAS should focus on removing the surface ships to make scoring the kill against the Boss more likely.
    • The DD or CVE needs to avoid taking too much damage to effectively kill the boss.

See: Formations. It is advised to use Line Abreast on most of the map:

  • Nodes B C G J K L
Diamond is advised on:
  • Nodes E M
For Boss P:
  • Depending on how the LBAS is setuped:
    • Line ahead is recommended if the LBAS can effectively kill the enemy SS.
    • Echelon or Double Line is preferred if the LBAS is not set to fight SS.

Resources and LBAS Farming

Doing this farming will bring a lot of "losses", which can impact overall win rate and thus "event eligibility".

It is possible to farm both fuel   and bauxite   by reaching node O.

  • 1-6SS(V)
  • Route = C D F J K M O
    • LoS required: ≥ 32 (Cn3)
  • A maximum of Ka-Mi Tanks  should be used as they provide the best earnings for submarines.
    • Drum-capable SS are recommended as a substitute, increasing the resource gains without requiring more Tank.
  • One submarine may be used as an LoS mule, carrying multiple   Seaplanes and  Submarine Radars 
     
     
     
    to meet the LoS requirement.
  • While this map has little to no threat against a full submarine fleet, J will have rare instances where destroyers may pop up in the composition that will damage the SS. Please be aware of this while farming this map.
    • Do not consider farming during Boss Last Dance, as J will be locked on this 2 Destroyer composition.

It is possible to farm for LBAS Plane Proficiency ❱❱ by sending the LBAS on a submarine node like J or K.

  • Just set-up an LBAS with any planes, according the final range is enough to reach J or K (3 range each).
    • Sending a surface-focused LBAS on J can assure a safer path. Such runs consume little to no resources on the LBAS.
