Tips

Clearing this map gives you 75 points and a medal. At the beginning of each month, the boss HP bar will be reset, thus allowing you to obtain the medal and bonus points again.

• Unlike quests, the time limit for all Extra Operation is 11:59 PM JST on the last day of the month. Defeating the enemy flagship after the time limit will not count towards either the previous month or the next month.
• If the HP bar did not reset for you, re-logging into the game typically will fix the problem.
• Enemy fleets along the route to boss are composed purely of submarines.
  • At various HQ level thresholds, enemy compositions will increase in difficulty, but if you train a fleet of Destroyers, Light Cruisers and Escorts and maintain strong ASW equipment it should be manageable.
    • Using Isuzu Kai Ni or any DD/CL that has ASW stats that go over 100, or DE that has an ASW of 60 or higher will allow them to perform a OASW attack, which can be very helpful on this map. It can easily turn this map to your advantage for the most part.

Recommended Fleet

• 1CVL, 1 BBV, 2 DD/CL - recommended for beginners.
  • Equipping the Saiun to the CVL will minimize the chance of Crossing the T - Disadvantage
  • At least 1 BBV is highly recommended as it is capable of performing ASW while also granting you a second shelling phase.
• If you happen to own Taiyou, she is highly recommended for this map as she's the only light carrier capable of fighting submarines efficiently.
  • At Kai, she's capable of Preemptive ASW attack using any ASW plane, making her the most resourceful light carrier to take out submarines on that map.
  • If you do not own Taiyou, any other CVL can work, but their damage output will be limited in comparison to her's.
• 2-4 DD/DE, 0-2 CL capable of Preemptive ASW attack is recommended for experienced players since the DD and CL will be able to perform two rounds of ASW attacks without the need for a BBV (useful if you want to save your resources).
  • Do not use more than 2 CL (CT and CLT don't count as CLs) in your composition if you are attempting the above set-up, or you will get routed to I.
• DE can be used in place of DDs for this map and are economically efficient for your resources in the process.
  • A full fleet of 4 DE will take a slightly different path (with easier sub enemies) over other compositions, but will still reach the boss node

Sparkling

• This map can now also double for Flagship Sparkling for any DD / CL, preferably with Preemptive ASW attack.
• Recommended Sparkling Fleet: 1 DD/CL with ASW equipment (Preemptive ASW attack is preferred, but not essential) as Flagship + 2-3 throwaway LV 1 DDs + Any other throwaway ships
  • By doing this, you can basically sparkle your DD while taking far less damage, aside from the occasional bad targeting roll.
  • Critically, this leveling method works best after level 80, as throwaway destroyers without ASW equipment are unable to defeat the armor of the most subs on the map, guaranteeing your flag an MVP.
  • Most importantly, by covering three nodes, you gain far more morale per node than you would from sparkling at 1-1.
  • If you plan to use throwaway DDs, be sure to not use DDs you plan to keep/train since you are likely to choose to scrap them afterward the sparkling process.

Notes

Akashi will drop with a small chance in 1-5 only for Admirals who have do not have her in your base. If you already have her, she will not drop in this map anymore. However, Akashi is still obtainable in maps like 3-5 or 6-2.
