E-1

E-1 Map

• 100 exp
• Node B contains 1 flagship and 1 Submarine Ka-Class Elite
• Killing the boss 6 times will empty its HP gauge. Not being able to kill it by the end of boss battle will still do some damage to the gauge.
• Boss is Heavy Cruiser Ri-Class Kai Flagship

Rewards
Furniture Fairy	Emergency Repair Personnel	Reppuu Model 11 (Reppuu Kai)	Medal

Branching rules

• A to B: Fleet with at least two CV(B). Fleet not meeting any rules goes random.
• A to C, and E to G: Fleet with at least two heavy cruisers (not aviation) and two ships carrying a total of 3 Drum Canisters.
• Recon aircraft are required to get to the boss node. Bomber seaplanes such as the Zuiun and Seiran are not considered recons.

Tips

• Use expedition 117 if you think you need more damage during sortie.
• Easy grinding setup : 2CA, 1CAV, 1DD, 2CLT (or 1CLT+1BB/CVL). Must bring total 3 drums on 2 ships (e.g. 2 on DD, 1 on CAV) and a seaplane with AA to gain air superiority. There will be no LOS requirement for A C E G H route and only two battle on your way to boss - best of all, you won't encounter any enemy carrier at all and gain some steel in node G for your repairs.

E-2 - Southwest of Zunda Strait - Across The Zunda Strait

E-2

E-2 Map

• 150 exp
• Map gauge has 6 hp
• Node H is night battle
• Boss is Battleship Ru-Class Kai Flagship

Rewards
Akashi	Medal

Branching rules

• 2 BB, 1 CLT, 1 CAV, 2 CV with BB and CAV equipped with Type 0 is really likely to reach boss node
• 2 BB, 2 CV, 2 BBv with 300+ LOS and Type 0 will 85% getting to boss node (so far).

Tips

• Expedition 117 can be use for extra damage during sortie.
• If pre-boss night battle is too hard, bring in a submarine with Emergency Repair + Turbine/Boiler, you must reach night battle before your SS sustains heavy damage (red hp). Do not set SS as flagship. Or you could use a searchlight.
• Using line abreast in the night battle node may help to lower damage from enemy attacks. (even though formation in night battle does not show up on screen)
• For the night battle node, Echelon + Searchlight can be highly effective for higher level fleets.

E-3 - Port Wine Area - Assault! Destroy Port Wine Operation

E-3

E-3 Map

• 200 exp
• Killing the boss 7 times will empty its HP gauge. Not being able to kill it by the end of boss battle will still do some damage to the gauge.
• Node-A contains 2 Submarine Ka-Class
• Node-B contains 3 Submarine Ka-Class
• Boss is Harbour Princess

Rewards
Amatsukaze	Medal 2x

Branching rules

• Using 4 BB + 2 CV with 312+ LOS seems to give a 100% chance to reach the Boss node
• From C to E:  2+ CVs (not CVL).  Other compositions are random between F and E.
• Using all fast ships(?), and/or CVL will sometimes result in route C-F-I. There are no air battles here, but I node is a night battle.
• A certain amount of LOS is required to reach the boss node L from preboss nodes H or I.

Tips

• Ships without high health & armor are susceptible to taking high damage from the enemy submarines.
• Avoiding the night battle node by bringing two CVs is recommended.
• Using Sanshiki gives you a damage bonus against the Boss, especially at night.
• Use expedition 118 if you think you need more damage in the boss node.

E-4 - Central Pacific Sea - Sweep Against Subs in the Frontline

E-4

E-4 Map

• Node C has no battle.
• Boss is Submarine So-Class Elite

Rewards
New Model High Temperature High Pressure Boiler	Emergency Repair Goddess	Ship Repair Facility	Medal

Branching rules

• From C to D: Fleet with 5 DD or 4DD + 1CL
• From C to E: Any other composition
• E to D or G is random

Tips

• Use Line Abreast in nodes A, E and H.
• If you're feeling lazy, equip your DDs with damage control. The boss torpedoes are rather inaccurate so it will rarely get used. However, it does sacrifice some space that could be used for more ASW equipment. Thus, this is only recommended for DDs with a set of Type 3 sonar/depth charge.
• Sparkle before you sortie for increased evasion. 
• A general guideline would be to put the CL/DD with the lowest evasion/armor in the flagship slot. For example, if your CL is Yuubari she will usually become the flagship, but evasion also depends on levels.
  • If the said flagship is Yuubari, equip her with a damage control and either of the +10 or +13 Turbine. Equipping her with a Damage Control will be a counter-measure should she received critical damage during the pre-boss node and allowing the player to continue without wasting effort. The turbine adds her evasion, reducing the chances of being damage.
• Night Battle is not recommended
• Recommended compositions:
  • 4 DD 1 CL and 1 BB. Equip BB with three main guns and a good surface radar.  Use double line at the preboss node. The BB's role is to damage enemy ships to reduce damage taken from them, and also giving an extra shelling phase at the boss. Using a BBV instead for anti-sub is unnecessary if your DDs and CLs are adequately equipped. AA equips such as 10cm HA are not recommended as the effect is slight and is outweighed by the utility of extra ASW or a damecon.
  • 4 DD 1 CL and 1 CV. Equip your CV with anti-air fighters and the rest of your fleet with ASW. The CV's role is to prevent enemy air superiority, and thus reduce damage taken in the shelling phase, mainly through the prevention of enemy double attacks. 
  • 4 DD 1 CL and 1 BBV loaded with seaplane bombers and/or Ka-type Observation Autogyro. This composition gives maximum ASW for killing the boss, but lower survival rate at the preboss node compared to the above compositions.
  • 2 DD, 2 CLT 1 BB(V), 1 CV. This is the safest but also most expensive composition. You will not always reach the boss, and will also have to face 4 battles instead of 3.

E-5 - North Pacific Sea - Capture Peacock Island Operation

E-5

E-5 Map

• Boss is Isolated Island Demon

Rewards
Sakawa	Medal 3x

Branching rules

• Starting point to A : Fleet contain 3 or more submarines.
• B → C : Fleet with fast ship only.
• B → D : Fleet with slow ship(s).
• From F or G to J (boss node) : A certain amount of total LOS required.
• From F to H or G to I : Failing to meet the total LoS requirement above or fleet contains 1 or more submarines. 

Tips

• Use at least one slow BB to avoid the fuel maelstrom at node C.
• 4 BB and 2 CV. Fill your Carriers with Reppuu (or better), put your best fighter in your carrier's largest slot, with this you can win air superiority in the boss node.
  • 3+ Fast BB sends you to south pre-boss node.
  • 3+ Slow BB (excluding BBV) sends you to south pre-boss node.
  • Other compositions seem to be random between north and south.
• 3 BB and 3 CV. Equip at least 6 Reppuu and 1 Reppuu Kai.
  • In contrast to the previous composition, you have room to equip bombers that allow your carriers to attack.  
  • This composition gets an arguably easier pre-boss node (north) guaranteed as well.
  • 5 Reppuu, 1 Reppuu Kai, and a Type 62 Zero Fighter-bomber is also sufficient for air superiority at the boss (assuming the Reppuu Kai is in Kaga's large slot), and provides slightly more firepower.
  • If you're unsure about what to equip for CVs, use this Air Superiority Calculator . Around 350 FP is the ideal number for E-5 Boss node's Air Superiority. 
• Equipment for battleships : Two 46cm, recon plane, Type 3 Shell (you will need type 3 to deal with the boss). Alternatively, you can add type 91 ammo or Type 32 radar instead of recon planes if you're not going for air superiority.
• Using Double Line or Line Ahead formation is recommended in E node.
• Choose Line Ahead in boss node to deliver highest firepower.
• Both support expeditions are recommended to increase damage output at all nodes.
  • 2 DD 2 CVL is a cost-efficient fleet.
  • 2 DD 2 CV/CVL 2 BB gives maximum firepower.
  • Remember, support expeditions only require the ammo to be resupplied after each sortie.  Half of each ships remaining fuel is used for each expedition, giving 4-5 runs before needing to refuel.
  • Sparkling, especially on the flagship, increases the chances of pre-boss support appearing.
• Some (real life) luck is required to sink the boss Isolated Island Demon, since her node also contains a Battleship Princess that is hard to sink.
• It is strongly recommended to sparkle your entire fleet, boosting your evasion against Battleship Princess in E node and the boss node.
