	H	SS≤2, or LoS check failed. High chance if [(F)BB(V) + CV(L) + CA(V)]≥2 or no LoS equipment carried. Small chance even with sufficient LoS.
F	I	Failed LoS check for K. Small chance even with sufficient LoS.
	J	Failed LoS check for K. Small chance even with sufficient LoS.
	K	LoS check with animation. Can still possibly drift to I or J even with sufficient LoS.

• The only map since 4-4 that does not have a gauge, but even B Victory takes some work here.
• At least 3 SS are required to reach the boss.
• There are LoS checks E -> F and F -> K. They do not have high LoS requirements (SSVs with a couple recon planes will pass), but an all-sub fleet without recon planes will be sent to H.
• Fleet composition for clearing purposes typically are one of the three types:
  • 1 CLT + 1 CL + 1 CV + 3 SS(V) (B -> D -> E -> F ->K): Effective fleet for taking out the boss but it will have to go through node B where there's a Ru-class Flagship.
    • CV may or may not wish to equip SCAMP, as it allows the CV to act first. Try to use armored CV so that it can attack even in chuuha.
    • Saiun is probably not a good idea for clearing purposes (you want to minimize damage taken along the route). Only consider that if you're using this fleet for the monthly quest (3 S Victory at 6-1 boss).
  • All all-sub fleet (A -> C -> D -> E -> F -> K): Allows the fleet to completely ignore any enemy ships that can't attack subs, however node C is pretty harsh on subs with late-model DDs and flagship CLs.
    • You pretty much want to count on cut-in attacks (at boss), so only use remodeled subs if you're using this composition. Note that you need recon planes for this map, and as SS(V) only have 2 slots, you may want to just give both planes to the same girl. You want as many submarines that are actually combat capable for this route, and yes, this means that you really need I-401 and/or U-511 (Ro-500).
  • Taigei + 3~5 SS(V) + 0~2 escorts (AorB -> D -> E -> F -> K): The shortest route in terms of number of battles. Taigei can also equip recon planes to free up slots for your SS(V)s.
    • The trade off is that any enemy ship still in lightly damage or better shape at the end of shelling phase will have fewer targets to launch their torpedoes at. Taigei (and escorts if any) also has to tank all the ships that can't perform ASW, which includes Wa-class Transport Elite at D, CA Ri-class Flagship/Elite and CLT Chi-class Elite at F.
    • You also have fewer opening torpedoes, which means there's a high chance of additional damage taken.
• Pattern 1 on node H has a chance to drop I-401 with S Victory. If you want to farm her there, 1 BB 3 CLT 1 CL 1 CV or 1 CL 3 CLT 2 CV both guarantee B -> D -> E -> H and are good enough to get S Rank.

Requires sinking the flagship at the boss node 3 times to deplete the gauge.

• Because of the amount of Tsu-class (and elite) in this map, CAVs and BBVs should keep 1 set of Type 0 recon (else they run the risk of not having any planes for artillery spotting fire). Similarly, CV(L) should preferably use bombers in larger slots (preferably a slot of 20 or higher).
• Compositions:
  • B-F-H/I-K : 1BB(V), 1CV, 2DD, 2CA(V) or 1BB(V), 1CV, 2DD, 2CLT; Passing an unknown LoS check sends you to I, otherwise to H
    • There is a LoS check for F->I. Using either composition that fails this LoS check will to go H instead. However, H does not contain any Flagship Kai-grade enemies, so failing this LoS check may be preferable. There is also a LoS check for H->K. 29~30.88 Refined LoS guarantees going H and passing the second LoS check. 31 LoS is similar but has a small chance go to I. 32+ LoS guarantees I.
    • Cons of this setup is the fact that you're using 2 DDs through nodes that are filled with things that can easily hit them for moderate or heavy damage.
  • B-F-E-H-K : 2CLT, 2CA(V), 2CV or 2CLT, 2CA(V), 1CV, 1BB
    • Higher chance to kill the boss, but not as efficient for farming. Can guarantee the H node path, though.
    • 2CV setup for this route might be better, as Pattern 1 at E node requires relatively large amount of AS (on top of boss having 50% chance of requiring 126 or higher air power for AS). Remember that you probably want bombers in larger slots so you don't run the risk of having them all shot down, rendering your CVs unable to attack during shelling.
  • A-D-G-K: CA(V), 2CL, 3DD (Unknown LOS check on G-K). Strongly recommended to use a CAV with at least a seaplane bomber.
    • Note that you only have 50% chance for air superiority/supremacy in this case (you won't have nearly enough AS for Pattern 2).

• Requires sinking boss flagship 4 times to clear.
• Only seaplane tenders, light cruisers, training cruisers, and destroyers allowed!

• Specifically at least 1 AV, at least 1 DD, and at least 1CL+CLp.
• No, 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, who makes its (her?) first appearance in a regular map. But avoiding So-Class requires an additional fight.

• CL Tsu-Class Elite can show up at node E.
• Node G can be guaranteed with 4 destroyers.

• Regarding Air Reconnaissance: 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.

• Neither G or H have combat.
• Animation will be shown for the Air Reconnaissance; if both Type 2 Flying Boat and other seaplanes are brought, Type 2 Flying Boat animation takes priority.
• Success rate (and possibly critical success rate) of the air reconnaissance depends on which AV and what equipment(s) are equipped, if any. Akitsushima equipped with Type 2 Flying Boat appears to increase the critical (and normal?) success rate.
• You forfeit all reconnaissance rewards if you either drift away from boss or lose at the boss node..

• Regarding Boss Fleet:

• Before the gauge can depleted, 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, 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/CLp/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 nighttime.

• Suggested fleet setup:

• 1AV, 1CL, 4DD (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.
• Cons: Lowest damage output of the setup; may not be able to consistently get a victory at boss.

• 1AV, Abukuma Kai Ni, 4DD (A → C → E → G → H → J, 3 fights total)

• Pros: Simlar to the composition above as it's cost-effective to getting to the boss fleet, and guarantees G branching, which allows two air reconnaissance rewards, but also can grant another pre-emptive torpedo salvo if Abukuma is equipped with a Type A Ko-hyoteki.
• Cons: Can still be a game of chance to score a victory at boss, but it more easier to achieve.

• 2AV, 3CL, 1DD (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.

• 1AV, 2CL, 3DD (Either of the above routes, 3 or 4 fights total)

• Pros: Has better damage over 1AV+1CL+4DD, 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 setup):

• 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 or Chiyoda equipped with 2 Zuiun (or variants) and 1 Type A Ko-hyoteki probably is the better choice, especially since the opening torpedo can easily take out a less-armored target before shelling begins. (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 recommenced 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.

• Requires destroying the Isolated Island Princess 5 times to clear.

• This map features multiple starting zone positions which were introduced in the Winter 2016 Event.
  • Ships consisting of a Torpedo Squadron (i.e. mostly DDs or CL and DDs) will start on left Side of the map
  • Any carrier will start on the east, as will any two battleships, or three CA(V)s
  • Not having two destroyers will also start on the west
  • You cannot bring no more than 2 CV(L)(B)
  • You cannot bring more than 2 (F)BB
• Recommended fleet composition:
• 1CL flagship, 1 FBB, 3DD, 1CAV
  • Gives the shortest and easiest route to boss - B,D,C,F,N.
  • Highly recommended only if you have enough WG42s, Daihatsu-class Landing Craft (Type 89 Medium Tanks & Marines) and Type 2 Ka-Mi Tank and had constructed a Seaplane Fighter.
  • Fleet has the best chance of reaching the boss node while maintaining fuel and ammo to allow for a better outcome in the boss fight.
  • It's highly recommended to have a seaplane fighter or an Italian ship to help aid you in maintaining air superiority / air parity over the fights on your way to the boss.
  • DDs and CLs are recommended to have WG42s and Daihatsu as these are the only effective ways to do damage to the Battery Imps and do decent chipping damage to the Isolated Island Princess, CAs and BBs should be armed with a Type 3 Shell against the installation bosses. BBs may also bring AP shells to help aid in doing daytime battle damage.
• 1 BB(V), 1 CAV, 1CL, 2 DD, and Akitsushima
  • Akitsushima allows for the shortest possible path on the west entrance going from A,D,C,F and N.
  • In this case Akitsushima should be armed with searchlight and 2 seaplane fighters as her role will serve to be a distraction and to maintain a degree of air superiority at the boss node depending on the formation.
• 2 CAV, 1CL, and 3 DD
  • Allows for A,D,C,F and N.
• More powerful set up in compared to Akitsushima but will result in some luck to ensure you'll deliver damage.

Regarding Boss Fleet

• Boss Fleet is heavily effected based on your HQ level.
• Admirals below HQ level 103 (as of currently known) will not feature the Supply Depot Princess in the boss composition. But will appear if your level is 103 or higher.
• Boss fleet's flagship is the Isolated Island Princess
  • Isolated Hime will usually have Battery Imps and Supply Depot Princess with her.
  • Dev tweet says Battery Imps are immune to Type 3 Shells but there are many reports of CAs and BBs doing high damage to them in yasen.
  • Using WG42 and Daihatsu will do decent damage to them.
  • If you have enough WG42 then you may want to use Ooyodo and equip her with 2 of them as they stack and can deliver severe damage and can easily one shot an Imp or one of the Hime.
  • Stacking Type 2 Ka-Mi Tank and Daihatsu-class Landing Craft (Type 89 Medium Tanks & Marines) upgraded with WG42 can do a lot of damage to Supply Depot Princess and Battery Imp.
