Rules
|
Start
|
|
- Go to C if fleet contains CV(B)
- Meet ANY of the following to go to D
- DD+DE = 6
- DD ≥ 3, CL+DD ≥ 4 AND meet one of the following
- Fast fleet
- Fleet contains CL
- BB(V)+CV(B/L) = 0 (FBB doesn't count)
- Go to A if DD+DE ≥ 2 AND fleet contains either CL or AO
- Otherwise, random routing between A and C
|
|
|
|
|
- Meet ANY of the following to go to B
- Fleet contains AO or AV
- Fleet contains CVL, CL, DD ≥ 2 AND CA ≤ 1 (CAV doesn't count)
- Go to D if CA ≥ 2 (CAV doesn't count)
- Otherwise, random routing
|
|
|
|
- Go to E if (F)BB(V)+CV(B/L) ≥ 3
- Fleet containing slow ship will more likely go to E
- Otherwise, go to G
|
|
|
|
- Go to D if fleet contains CL, DD ≥ 2 AND no SS(V)
- Go to F if fleet contains (F)BB(V)+CV(B/L) ≥ 4
- Otherwise, random routing (More likely to go to F)
|
|
|
|
- Go to K if fleet contains SS(V) or no DDs
- Go to H if fleet contains DD ≥ 2, (F)BB(V)+CV(B/L) ≤ 2 AND the fleet is fast
- Otherwise, random routing
- The higher amount of DDs in the fleet, the better chance to go to H
|
|
|
|
- Go to J if fleet contains no CV(B/L)
- Otherwise, random routing between H and I
|
|
|
|
|
- If CV(B/L) = 2, 90% N, 10% I
- Otherwise, 75% N, 25% I
|
|
|
|
- Meet ANY of the following to go to L
- DD ≤ 1
- CV(B/L) ≥ 3
- Fleet contains SS(V)
- Otherwise, random routing
|
|
|
|
- Meet ANY of the following to go to M
- (F)BB(V)+CV(B/L) ≥ 5
- CL+DD+DE = 0
- CV(B/L) = 0
- Go to N if (F)BB(V)+CV(B/L) ≤ 2 AND no SS(V)
- Random otherwise

Tips
This map will serve as a first introduction to Installation type Abyssal, which is different from all other abyssal types as they tend to have higher armor, stronger attack power and, can't be hit by torpedoes.
- Killing the installation is optional for clearing the map. However, having a fleet that is capable of killing an installation is encouraged especially for first-time users of anti-installation gear to get a feel for fighting these kinds of bosses.
- As such, the following equipment should be considered to fight the Harbor Princess, the following gear are effective at penetrating the Soft-Skinned Installation's armor:
For beginners:
AA Shells (for BB/CA).
For more advanced players:
Anti-ground Rocket Launchers

and
"Landing tanks".
Aircraft carriers CANNOT attack installations if they have a
equipped UNLESS its one of the dive-bombers from the following list:
Expand 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.

A strong composition, but that will fight more pre-boss battles.
Dealing with Harbor Princess is slightly easier as CA(V) can carry AA Shells to damage her.

Fleet Notes
|
A light fleet composition which takes the shortest path to the boss. Since it is limited to light ships, Nuke set-ups are recommended to effectively fight the installation boss. CVLs equipped with anti-installation bombers can also be used for additional assistance taking out the installation.
- Keep in mind though it is not entirely necessary to kill the boss for this map.

Resource Nodes
B J are "Normal Resource Nodes" rewarding respectively fuel
, and bauxite
.
- See here for more details.
It is possible to use this map to farm both fuel and bauxite. This requires the use of either an AV/AO and will go through 2 combat nodes:

Fleet Notes

Node A should not present much difficulty, however, node G may present some challenge to pass.
- AV, CLT, and CL carrying
Minisub Midget Submarine can be useful for taking out many of the ships in node G during the Otorp attack, to minimize damage taken.
Slow AV/AO needs to be Fast (see Improving Ship Speed).
Due to the danger this path has, bringing to gain extra resources can be optional.
