Tips

This map is mostly randomized on the path taken, with few notable exceptions that should be considered:

  • Avoid bringing too many (F)BB(V) and CV(B/L).
  • A well-balanced fleet is recommended for tackling this map.
  • While dedicated ASW setups are not necessary, mixed ASW set-ups can be considered for DDs.

Fleet Notes
Cheapest composition, but requires high-level CL and DD as they need to dodge the closing torpedo if they didn't disable all of the enemies CA, CL, and DD in advance.

Fleet Notes
Heaviest comp, with a slightly harder pre-boss, as you will always go to Node G where Battleship Ta-Class are awaiting, in exchange, you get to bring CV(B/L) for opening airstrikes and more firepower on the way to the boss and at the boss node itself.
