World 4

Drops
Notes:

B, G and H are submarine nodes.

Nodes and Enemy Encounters
Notes: Node B drops 20% of your remaining fuel in the fleet without radar (電探). Fleets with radar drops 25 fuel.

C and F are submarines nodes

World 4-3:  リランカ島空襲
D, F and K are submarines nodes with mostly or only submarines.

Node G always has a single submarine accompanying the enemy fleet.

Boss Node I may have a single submarine. (2 out of 3 possible combination)

World 4-4:  カスガダマ沖海戦
F and I are Submarine Nodes.

Tip: 2 DD and 1 CA is needed to go to Node F to Node G. This is the easiest way to the boss (A-F-G-H)

Important: This will be your first map where simply defeating the boss node is not enough to 'defeat' the map. You must kill the flagship boss FOUR times before being allowed to pass. Keep in mind that the boss node changes @ 25% of the map health (i.e. after SINKING the boss 3 times), usually to a 'stronger' form.
