World 5

Tips

 * Two CA/CAV to guarantee sortie start->A, and H -> I (boss) route
 * Two DD for C to H.
 * Node D is an all sub node, Node A has 2/3 chance of having one sub, and Boss Node I 1/3 chance of having one sub
 * A convenient place to level subs. Node D is all subs--neither side can harm each other--and rewards 750 exp for a D rank clear, though moving to node A can result in heavy damage.

Tips

 * Killing the boss will bring down map meter 25%. You need to defeat the boss 4 times, and she will turn into a stronger form in the last battle. Map meter does not regenerate.
 * Considering the difficulty of the map compared to others, this is a very good map to train on if you are bored with 3-2. Bar Node G, you can intentionally send fleets to get you to node J and generally defeat easy fleet comps. This is not resource or repair friendly though (since you will get damaged one way or another).

Tips

 * All nodes, except end nodes, are night battles only; there's also a submarine node if you have any slow ships in your fleet.
 * Sinking the Flagship Wa-class transport ship at the boss node will lower the boss gauge by 20%. You need to do this 5 times to clear the map.
 * 2DD, fast ship, and high torpedo stat (for night battle) is recommended. You can also use an all submarine fleet, but it will often be directed to J instead of Boss.
 * Taking advantage of night battle equipment (Star Shell, Searchlight, Type 98 Recon Seaplane (Night Scout) ) is recommended and Sparkling your ships should be considered as well.
 * Unless you need S rank for drops, you do not need to destroy the Hime nor the submarine and can bring a light fleet to deal with the Flagship Wa-class transport to clear the map.
 * Although the S rank on boss gives you decent drops on this map, it is highly advisable to just disregard the S rank boss drop here, and settle for A or B rank. All the drops here can be farmed later in next maps, which is easier to produce S rank on the boss.
 * There's a gold submarine in the boss node. A possible tactic is to bring 1 CL flag with heavy ASW gear and 5 DD, enter battle in Line Abreast formation to deal with it quickly, get less damage from enemy ships and thus focus on night battle. This fleet composition is the most resource efficient and can often succeed. Try double line or echelon on pre-boss nodes to absorb enemy cut-in attacks better.
 * Another possible strategy is to run 2 Fast Battleships, 2 CA(V) and 2 DD. This has a high chance of reaching the boss node and can get a lucky kill on the Wa-Class, but is extremely expensive in fuel, steel and ammo. Make sure not to equip bomber seaplanes so that your ships do not target the SS. A variation of this is to replace 1-2 CA(V) with CLT, but 2 CA(V) should be used for the final form because of the changes in boss composition.
 * A possible strategy is to run 3 CLTs, 1CA(V), and 2 DDs. This is the most efficient with highest Attack power/torpedo and lowest possible encounter rate (C-D-I-K)
 * Akitsumaru can gain air superiority at boss node with 2 Reppu + Type 52 Zero Fighter or 3 Shiden Kai 2 enabling artillery spotting for your fleet. Keep in mind that she is a slow ship so you will suffer at submarine node instead.
 * The new Aircraft Proficiency system allows Akitsumaru to gain air superiority at boss node with 2 fighter planes such as Shiden Kai 2 or Reppu at maximum proficiency. Air supremacy can be achieved with 3 Shiden Kai 2 at maximum proficiency.
 * Both enemy and ally submarines do not have increased evasion during battles STARTING at night, i.e. hitting them is as easy as in any day battle.
 * Another possible tactic is to send a fleet consisting of 4 or more SS. This composition is very resource-efficient, but the drawback is a lower chance of going to the boss node from I (25%). This lower chance is often offset by the higher rate of making it to the pre-boss node without suffering critical damage, allowing to clear the stage in 20-30 sorties on average (depending on ship levels). A SS fleet tends to go to node B, where you can avoid damage by getting a C rank.

Tips

 * Like 5-3, you must sink the boss battle flagship 5 times to complete the map.
 * Clearing this map with a Submarine Fleet consisting of 5-6SS is possible; However, there is a high chance that your SS won't hit the Flagship in the boss node, but the cost for resources and repair are very minimum (around 50-100 resources per run).
 * Using level 60+ SS (with at least maxed armor and torpedo stat) is advised, since there are several flagship DD and CL equipped with sonars and depth charges.
 * This composition is best when you'd like to farm some BB or CV to feed your fleet. If your SS level are high enough, with decent torpedoes, this composition can also be used to farm rare drops and admiral exp for the ranks.
 * Nodes G and I are night battles.
 * Node I is a submarine node.
 * Node H contains Carrier Demons while nodes K and N contain Carrier Princesses
 * For farming rare ships, Admiral exp or just boss kills to unlock 5-5, recommended formation is a flagship that can carry 4 drums (Yuubari, Ooyodo, CAV), any combination of 3 FBBs and/or CLTs, and 2 CVs. With this formation you only need to fight Nodes A and H before reaching the boss. Using Diamond formation at Node H also reduces the chances of enemy ships targeting your flagship.
 * The highest power variation of this is a fleet with 5 CVs and 1 Tone-class CAV equipped with 4 drum canisters. When equipped with >> torpedo bombers, bombers and enough fighters for air supremacy at the dual carrier oni node variant, the composition will consistently kill 4-5 ships out of 6 in the initial strike, and occasionally kill the entire enemy fleet in the initial strike at all nodes. As compared to adding FBBs or CLTs to the mix, this variation costs more bauxite (~ 250 per full sortie), but has virtually no repair costs, close to zero risk of retreat and lower ammunition costs.
 * Another option is to use a fleet with lowest resource consumption possible while getting maximum fuel income from node M, this will require 3 ships with 9 drum canisters equipped (2 Mogami or Tone class CAV with 8 drum canisters, Akizuki-class DD with one drum canister, HA mount and air radar for anti-air cut-in) and 3 standard carriers for air supremacy at the node H as well as preemptive strikes (Unryuu-class or Shoukaku/Hiryuu/Souryuu class at Kai, 6 >> fighters (Reppuu or better, any number of Type 0 Fighter Model 21 (Skilled) also can be used) and 6 of your best >> torpedo bombers, there is almost no risk of losing their ranks), this should result in minus ~160-180 (plus 180 from node M, minus ~50 for repairs, high level ships are recommended) fuel, ~180-210 ammo, ~120 bauxite and ~1 bucket per run.
 * There are people who intentionally choose not to clear this map, they do this for ranking purpose as the final version of this boss does not include ships that hurt SS and thus it allow SS to B-win or above this node fairly easy and thus making the node stay in its final formation help boosting player's senka.

Stage Guide

 * You must sink the Boss Standard Carrier Wo-class Kai Flagship 5 times to clear the Map.
 * Nodes C, H, K and M are night battles.
 * Having 4 ships capable of equipping Drum Canisters (DD/CL/CAV) and a total of 5 Drum Canisters will take you to node B. Other compositions will always take you to node A.
 * Fleet with 3 SS or more will take you to node F, where there are enemy CLs and DDs with ASW.
 * Fleet with only fast ships will take you to node D. It is possible to bring slow ships if the fleet has 2 CV and 1 CVL. Other composition will take you to node C, where you will meet 6 enemy SS in night battle.
 * The recommended fleet composition is 3 BB, 2 CV and 1 CVL for maximum firepower and survivability.
 * After the introduction of the air proficiency, a fleet composition of 2 FBB and 4 CV is also recommended. This strategy focuses on a powerful opening airstrikes with many torpedo bombers. As long as a fighter power is maintained above 420, planes shot down should be minimal.
 * There is a sub at the boss node. Getting S rank at the boss is possible, but not recommended. It is advisable to ignore the sub and just settle for an A or B rank.
 * Using submarines in the map (3 BB 3 SS) taking you to A-F-G-N is possible. 3+ SS gets you to node F but more than 3 SS gets you to node H instead of N.
 * Clearing this map rewards 1 medal and 200 points for ranking. The boss HP bar is reset at the beginning of each month, allowing the reward to be obtained again.
