Phase 1/World 5/5-5

Tips

 * You must sink the Boss Standard Carrier Wo-class Kai Flagship 5 times to clear the map.
 * Clearing this map rewards 1 Medal and 200 ranking points. The boss HP bar is reset at the beginning of each month, allowing the reward to be obtained again.
 * 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 equipment.
 * 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.
 * 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 focus on killing the boss.
 * Fleet Compositions
 * High endurance ships are recommended (Yamato-class, Iowa, Shoukaku-class armored carriers, etc.), with anti-torpedo bulges equipped in expansion slots due to the threat of the high firepower and high torpedo Re-class battleships throughout the map.
 * With all carrier compositions 420 air power (plus 5-10 extra if utilizing jet aircraft) for achieving air supremacy at the first node and superiority/supremacy at all subsequent nodes is desired.
 * 3 BB, 2 CV, and 1 CVL high firepower and survivability (Yamato-class BB are preferable). Consider not bringing Saiun with this composition. This composition often utilizes a flagship CVL with no bombers equipped.
 * 1-2 FBB and 5-4 CV is also recommended. This strategy focuses on a powerful opening airstrikes with many torpedo bombers.  Saiun can be used with this composition to boost contact rate along with 1-2 seaplanes and named torpedo bomber squadrons.
 * Using exactly three submarines in the map (3 BB and 3 SS) routes A-F-G-N. However, pre-boss support shelling is needed to increase consistency of the submarines surviving. This route has the advantage of guaranteed boss routing, making it good for experienced players with high-end equipment and ships.
 * Other variants include 1 CV 2 CVB and 3 SS which has greater consistency surviving enemy ASW without support, but lower overall firepower at the boss node.
 * 1 Musashi Kai Ni 2 CVB and 3 SSV can be utilized as well, with seaplane fighters on submarines and Musashi Kai Ni to augment air power.
