	F	AS Is in the fleet
G	H	Meet ALL of the following requirements: Amount of SS(V) ≥ 3 Amount of BB(V) + CV(L/B) + CA(V) ≤ 1 Pass the LoS check: ≥ 16 (Cn4) Routing becomes random if 12 ≤ LoS ≤ 15.9 (Cn4)
	I	Meet ANY of the following requirements: Fail the LoS check Amount of SS(V) ≤ 2 Amount of BB(V) + CV(L) + CA(V) ≥ 2 If the fleet does not contain AS: 15% chance of off-routing to I regardless of LoS check result
H	E	Always node E if LoS ≤ 20 (Cn4) If the fleet contains AS: Always node K if LoS ≥ 25 (Cn4) Random between E and K if 20 ≤ LoS ≤ 24.9 (Cn4) If the fleet does not contain AS: Always node K if LoS ≥ 36 (Cn4) Random between J and K if 25 ≤ LoS ≤ 35.9 (Cn4) Random between E, J and K if 20 ≤ LoS ≤ 24.9 (Cn4)

Tips

• At least 3 SS(V) are required to reach the boss.
• There are LoS checks at G H and H K. They do not have high LoS requirements, but an all-submarine fleet without recons/radar can be sent to I.

• You may also need to use a "New Submarine Torpedo Cut-In" :

Recommended fleets

• 1CV, 1CL, 1CLT, 3SS(V)
• Route = C F G H K
  • Has a 15% chance to off-route to Node I
  • Most effective fleet for taking out the boss but it will have to go through node C where there's a Ru-class Flagship.
• Using a Midget Submarine
  
  on both your CL & CLT gives you a powerful Opening Torpedo Salvo (Otorp).
• For your CV, either:
  • CV may use several Jets
    , adding the Jet Assault phase to your already strong Otorp, allowing you to wipe all pre-boss fleets before they can attack you.
  • CV may or may not wish to equip any range extander as it allows CVs to act first after the Opening phases, like :
    • Jets
      
    • Long-range bombers
      
    • SCAMP
    • NOAP Skilled
    • Type 2 Reconnaissance Aircraft (only for Hiryuu Kai Ni or Souryuu Kai Ni)
• Try to use a CVB so that it can attack even in Chuuha.

• 6SS(V)
• Route = A D F G H K
  • Allows the fleet to completely ignore any enemy ships that can't attack SSs, however node D is pretty harsh on SS with late-model DDs and flagship CLs.
  • You pretty much want to count on Opening Torpedo Salvo (Otorp) & cut-in attacks (at boss), so only use remodeled SS if you're using this composition.
  • You may need recon seaplanes or Submarine Radars
    
    for this meet the LoS requirements.
    • If opened, the Submarine Radars can be fitted in an Reinforcement Expansion.
  • As SSVs have few slots, you may want to just give all your seaplanes to the same SSV. You want as many combat-capable submarines for this route.

• 1AS, 1CL, 4SS(V)
• 1AS, 2DD, 3SS(V)
• Route = A F G H K
  • The shortest route in terms of the number of battles.
  • 1AS combined with at least 2 SS(V) unlock the "Submarine-Tender Touch", a special attack that can trigger several times in the map, consuming a Submarine Supply Material each time.
  • The AS can equip recon seaplanes to free up slots for your SS(V)s.
  • A trade-off is that any enemy ship still in light damage or better shape at the end of the shelling phase will have fewer targets to launch their torpedoes at, so the AS and its escorts have to tank all the preboss ships that can't perform ASW.

Node I has so good drops like I-401 .

• If you want to farm there, you can use:
  • 1BB, 3CLT, 1CL, 1CV
  • 1CL, 3CLT, 2CV
  • Route = C F G I
