Tips

Unlocked by clearing both 4-4 and 5-1. To complete the map, you need to defeat the boss flagship 5 times.

  • 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 comp will be reverted back to Initial Form post-clear until the next month reset
  • Boss is a Harbor Princess, an installation-type enemy.
    • Warning: Harbor Princess becomes substantially stronger on final form! The changes are, namely:
      • HP increases from 380 to 490.
      • Base firepower increases from 100 to 180.
      • Armor increases from 135 to 183 (Counting equipment)
      • This pushes her armor roll values from 128 to 236 (i.e. 183 (±30%)), above the daytime cap of 181. Barring low armor rolls, only critical hits will significantly damage her during the day.
      • Base AA increases from 150 to 170.
      • She gains a completely different set of equipment: Two 15-inch Fortress Cannons, AP Shell, and what is suspected to be Abyssal Avenger Torpedo Bomber. As a side effect of her equipment, her range is increased to long.
      • The changes allow her to hit harder and earlier during the daytime. Since she's an installation-type abyssal ship, she uses the carrier damage calculation formula (even though it is displayed as shelling). Thus, her shelling damage, not counting her equipment or the bonus from AP shell, is already over the day battle cap even with Red T engagement. She also gains double attack ability during night battle.
      • On the final form, her escort ships also become tougher (Elite/Flagship Transports and Elite CA Ne-class replaces the DD Late Model).

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 handful 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.
