Information from the official Twitter:

1. Event Name "Recon planes, launching!"
   • High LOS will be the key to increase the chances of reaching the boss nodes.
   • To achieve a high value, use of seaplanes, recon aircraft and ships with high LOS is strongly recommended
   • A special animation plays showing your planes attempting to find the node when approaching. If there is a positive reaction from your fleet's leader, you will then proceed to fight the boss.
2. Event lasts 2 weeks from April 23rd.
   • Boss health in this event does not regenerate so stay calm and don't rush. Take it easy.
3. Requires at least 75% sortie win ratio to participate.
   • At least 5 free ship slots for new girls to join your fleet before sortie.
   • At least 20 free equipment slots before sortie.
4. 4 new ships added: DD Amatsukaze, DD Tanikaze, repair ship Akashi, and CL Sakawa.
   • Amatsukaze is an E-3 Reward (Port Darwin Area).
   • Tanikaze can be obtained from drops (E2, E3, E4 boss nodes are confirmed to drop her).
   • Akashi is an E-2 Reward (Battle of Sunda Strait), she can repair ships mid sortie (down to moderate damage). A new item, Ship Repair Facility, allows her to repair 2 ships at the same time. The times where she is allowed to repair are limited, however, she will get more functionality in the future.
   • Sakawa is an E-5 reward.
5. Tone, Chikuma and Bismarck received a second remodel, with Tone-class being reclassified as CAVs. This can be unlocked by using a special Blueprint item, obtainable by trading Extra Operation and Event maps badges.
6. New BGM added.
7. New Recon Plane functionality:
   • Increased effectiveness in the aerial combat phase from successful scouting with carrier-based scouts and seaplane scouts
     • Effect depends on whether air superiority or air supremacy is obtained
   • Special bonus in shelling phase from seaplane scouts
   • Achieving Air Superiority / Air Supremacy allows ships with Recon Planes to do Double Attacks and Cut-Ins during Day Battle
8. Reward for clearing event maps:
   • E-1: Medal, Reppuu Kai, Contruction Fairy, Damecon.
   • E-2: Medal, Akashi.
   • E-3: Medal x2, Amatsukaze.
   • E-4: Medal x1, New High-pressure, High-temperature Steam Boiler, Ship Repair Facility, Damecon

E-1 Map

• 100 exp
• Node B contains 1 flagship and 1 elite Ka-class submarines
• Rewards Furniture Fairy, Emergency Repair, Reppu Kai, and a Medal upon clear
• 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 CA Ri-Class flagship Kai

Branching rules

• A to B :Fleet with at least two standard carrier (Taihou included. Light carrier won't count). Fleet not meeting any rules goes random.
• A to C, and E to G :Fleet with at least two heavy cruiser (not aviation) and two ships carrying total of 4 drums (E.g. first ship bring 3 drums, another ship bring 1 drum).
• CLT-CLT-CAV-BB-CV-CV seems to be the best fleet composition so far.
• Recon aircraft are required to get to the boss node. Bomber seaplanes such as the Zuiun and Seiran are not considered recon planes.

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.

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)

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

E-4

File:6-4.jpg

E-4 Map

• Rewards New High-pressure, High-temperature Steam Boiler, Repair Goddess , Ship Repair Facility and one Medal upon clear
• Node C has no battle.
• Imuya, Goya, and Hachi drop on all nodes of this map.
• Boss is Submarine So-Class Elite

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 double line formation for pre-boss node, and line abreast for the rest.
• If you're feeling lazy, equip your DDs with damage control.
• Recommended compositions:
  • 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.
  • DD BB DD DD DD CL.  Equip BB with three main guns and a good surface radar.  The BB's role is to damage enemy ships to reduce damage taken from them.  Using a BBV instead for anti-sub is unnecessary.

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

E-5

E-5 Map

• Rewards Sakawa and three Medals upon clear.
• Boss is Isolated Island Demon

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) : With a certain LOS, otherwise, send you to dead end (H or I)
• From F to H or G to I : Low Fleet LoS or fleet contains submarine. 

Tips

• Use at least one slow BB to avoid the fuel maelstrom at node C.
• 4 BB and 2 CV. Fill your Carriers with Reppu (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 preboss node.
  • 3+ Slow BB (excluding BBV) sends you to south preboss node.
  • Other compositions seem to be random between north and south.
• 3 BB and 3 CV. Equip at least 6 Reppu and 1 Reppu 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 preboss node (north) guaranteed as well.
  • 5 Reppu, 1 Reppu Kai, and a Type 62 Zero Fighter-bomber is also sufficient for air superiority at the boss (assuming the Reppu Kai is in Kaga's large slot), and provides slightly more firepower.
• 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.
• 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.
• 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.
