Tips

Regarding the map

• Requires sinking boss flagship 4 times to clear.
  • Once the map is cleared, you can no longer roll the Final Form at the boss node
• Only seaplane tenders, light cruisers, training cruisers, and destroyers allowed! Specifically at least 1 AV, at least 1 DD, and at least 1 CL. Torpedo cruisers (CLT) cannot be used here.

Specific node notes

• Node C is a submarine node, but you will not get the normal indication that it is a submarine node. Node B can be a submarine node, but isn't always.
• There is very little reason to head towards B, unless the fleet cannot (or do not) want to face SS So-Class Elite at node C. But avoiding So-Class requires an additional fight which is not preferable
• CL Tsu-Class Elite can show up at node E.
• Node G can be guaranteed with 4 destroyers in the fleet.

Regarding air reconnaissance mechanic

• From nodes G and H, recon planes will be flown towards the green X (the recon route is shown on the map as green arrows). Successful reconnaissance will reward additional resources upon winning at the boss node(B rank or higher).
  • Neither G or H have combat.
  • Animation will be shown for the Air Reconnaissance; if both Large Flying Boats and other seaplanes are brought, Large Flying Boat animation takes priority.
  • Success rate (and great success rate) of the air reconnaissance depends on the LoS and slot sizes of Seaplane Recon, Seaplane Bombers and Large Flying Boats brought.
  • You forfeit all reconnaissance rewards if you lose at or do not reach the boss node..

Regarding Boss Fleet

• Before the gauge can be depleted (Initial Form), the boss fleet consists of 1~2 BB Ta-Class Flagships, 1~2 CA Ri-Class Flagships, 0~1 CL He-Class Flagship, the Destroyer Princess (weaker version), and 2 late model destroyers (either Ro-Class, Ha-Class, or Ni-Class). The two destroyers appearing will be the same class.
• When the gauge can be depleted (Final Form), the boss fleet is led by Destroyer Princess (stronger version), 2 BB Ta-Class Flagships, 1 CA Ri-Class Flagship, and 2 DD Ni-Class Late Models.
  • Because you can only deploy AV/CL/CT/DD, it is unlikely for the player's fleet to be able to inflict significant damage during daytime battle. You should expect the battle to last into night time.

Recommend Fleet

• 1 AV, 1 CL, 4 DD (A → C → E → G → H → J, 3 fights total)
  • Pros: The most cost-effective way to get to boss, and guarantees G branching, which allows two air reconnaissance rewards. CL can be Abukuma Kai Ni in order to grant yourself another preemptive torpedo salvo if she is equipped with a Type A Ko-hyoteki.
  • Cons: Lowest damage output of the setup and may not be able to consistently get a victory at boss.
• 2 AV, 3 CL, 1 DD (A → C → E → F → H → J, 4 fights total)
  • Pros: Highest damage output at boss, especially due to the boss fight almost always requiring night battle
  • Cons: Needs to fight an extra battle against enemy fleet led by a CA Ne-Class Elite which has the stats close to a battleship.
• 1 AV, 2 CL, 3 DD (Either of the above routes, 3 or 4 fights total)
  • Pros: Has better damage over 1 AV 1 CL 4 DD, and if the random compass sends you to G node, can fight at boss with better output and still only fighting 3 battles total.
  • Cons: Has to deal with RNG, and being sent to node F this way hurts a bit more.

Suggested Ships (and equipment setups)

• AV: Despite the fact that Akitsushima with her flying boats can succeed at the air reconnaissance better, her battle output is low, and as the boss fleet is rather tanky, using either Chitose, Chiyoda or Mizuho equipped with 2 Zuiun (or variants) and 1 Type A Ko-hyoteki is the better choice, especially since the opening torpedo can easily take out a less-armored target before shelling begins. If aviable, Nisshin A will be the best choice as AV, since her 4 slots allow her to equip Zuiun for Air Superiority and Artillery Spotting, Two main guns for day- and nighttime double-attack and a minisub with a potent opening Torpedo. (Akitsushima cannot equip Type A Ko-hyoteki, lower plane capacity, and no torpedo capability, period.) Note that any setup with seaplane bombers have chances being shot down, especially if Tsu-Class Elite shows up at node E, which may result in no air superiority at boss node.
• CL: Generally, your 1~3 best CLs here. Unless your other ships can compensate for the lowered night battle damage, it is not recommended to use Ooyodo here. Abukuma Kai Ni is highly recommended for here since she can be armed with a Type A Ko-hyoteki.
• DD: Consider the boss fight will require night battle for the most part, and the fact that Destroyer Princess (harder version) has 115 armor, it is better to bring ships that have better night battle performances. Anti-Air equipment is not required for this map because no enemy fleets here have air capability.

Air Reconnaissance

From Kancolle Kai, the formula for Air Reconnaissance is

[math]\displaystyle{ R = \sum_{\text{Seaplane Recon, Bombers}} \text{LoS} \times \sqrt{\sqrt{\text{No.}_\text{planes}}} + \sum_{\text{Large Flying Boats}} \text{LoS} \times \sqrt{\text{No.}_\text{planes}} }[/math]

For node G, the minimum [math]\displaystyle{ R }[/math] to achieve success is 12 for G and 16 for H. For Great Success, the requirement is multiplied by [math]\displaystyle{ (1.6 + rand(0.6)) }[/math].

This means that the minimum and maximum requirement for Great Success for H is 25.6 and 35.2.
