Tips

To complete the map, you need to defeat the boss flagship 5 times.

• The boss comp will revert back to its initial Form after clearing.
• Clearing this map rewards 180 Ranking points and a medal.
• The map will reset at midnight JST at the beginning of every month.

• The boss is a Soft-Skinned Installation type enemy. It is Strongly Recommended to equip Type 3 Shell
  
  on BB/CA(V) or Anti-ground Rocket Launchers
  
  on CL/DD if applicable.
  • Specific Landing tanks
    
    also work, including Daihatsu(+T89 Tank) if .
  • Aircraft carriers CANNOT attack installations if they have a equipped UNLESS it's one of the dive-bombers from the following list:

Dive-Bombers that can attack installations
This is a segment from a bigger article. See Combat/Anti-Installation for details on Installation mechanics. Carriers will only attack installations in the shelling phase if equipped with Torpedo Bombers or Anti-Installation Dive Bombers. Additionally, carriers will attack installations if equipped with non-special dive bombers AND one of the special dive bombers below. Any other dive bomber will completely disable shelling against installations even if the carrier has a torpedo bomber equipped. This can be very useful to manipulate the targeting mechanic so the carriers attack important targets.

• Node D is a submarine node, but it's advised to ignore it so you can focus on killing the boss.

Recommended Fleet

• 3CV/(F)BB(V), 3CA(V)
• 2BB, 1CV(B), 2CA, 1CAV
• 1BB, 2CV(B), 1CVL, 2CA(V)
  • Route = Random:

  A D H K T

  C D H K T

  • Please beware that Node K has a chance to Heavily Damage your ships due to the presence of 1 or 2 Battleship Ru-Class Kai Flagship
  • LoS required for the boss is 71 (Cn2)
  • CVB are preferred against regular CV for their ability to still being able to attack when Chuuha, which is very helpful after passing through Node K.

• 1-2(F)BB(V), 2-3CV(B), 2CA(V) (Fast+)
• 3CA(V), 3CV(B) (Fast+)
  • Route = Random:

  A D H T

  C D H T

  • Skips Node K over the standard route.
  • Will only go through the SS Node D and a Light Enemy Fleet in node H before going straight into the Boss Node.
  • All Ships are highly recommended to have been fitted with a Reinforcement Expansion to be equipped with enough Speed modifiers
    
    to reach Fast+ speed.
  • The exchange is that your BB(V)/CA(V) won't be able to do Artillery Spotting due to being unable to equip seaplane, though as they will still be outfitted with 2 Main Guns, they will still be able to do Double Attack during Night Battle.
  • It is highly recommended that the CV(B)s are all outfitted with CVCI to be able to deal with non-Installation Escort Ships quickly and efficiently.

Like Fast+ routing, you will also skip node K which contains dangerous enemies but it can be difficult to defeat Harbour Princess at the boss, especially in her Final Form.

• 2(F)BB(V)/CV(L/B), 1CL, 3DD
  • Route = Random:

  A D H T

  C D H T

• 1FBB, 2CVL, 1CL, 2DD (Fast)
  • Route = Random:

  A B E M N T

  C F I J H T

• Four-slot DD or CLs are useful in this situation as they can carry double Anti-ground Rocket Launchers
  
  to deal significant damage to Harbour Princess.
• Only useful to do the quests that require you to take CLs/DDs into 4-5 Boss, or to attempt to save cost from supplying and repairing ships.
