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).

   • 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.

E-1 Map

• 100 exp
• Node B contains 1 flagship and 1 elite Ka-class submarines

Branching rules

• CLT-CLT-CAV-BB-CV-CV seems to be the best fleet composition so far, with reported LoS of 298 to 408.
• Some compositions have been reported to reach boss node with LoS of 226
• 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.
• BBV with Recon aircraft get critical frequently.

Tips

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.
• Boss is Submarine So-Class Elite

Branching rules

• From C to D : Fleet with 5 DD or 4DD + 1CL . The sixth ship can be any battleship or carrier. Fleet with less than 4 DD or have 2 BB/CV will always send to E
• E to D or G is random.
• An alternative is using 2DD, 2CL, 1 BB, 1 CV. This is a high risk high reward setup and only works if you have high leveled DDs or CLs (Recommended Verniy, the Kai 2s, Yukikaze or Shimakaze followed with Izusu and Yuubari). This setup is not a 100% chance to get to the Boss node but the chances are still high, and you may find yourself retreating often. However, If you manage to survive to the Boss node, it can be easily defeated and get a S score. 
• You can also use 1CV with 5DD (or 4DD 1CL) to ensure A C D H route and won't lose air superiority to the enemy in the pre boss node, you will take much less crit in this way. The downside is you may fail to kill the boss if your ASW gears are bad, no BB means no second attack for your ships. If you want a battleship , fill your BBV with your best seaplanes to enable ASW.
• Having a CLT instead of a CL will not send you from C to D with a fleet of 4DD + 1CLT + any battleship or carrier; you will be sent to node E

Tips

• Use diamond formation for pre-boss node, line-abreast for the rest.
• Pre-boss node is very tough if you have no carrier and let the enemy get air superiority, your DD will get crit to red very frequently.
• Equip your ships with AA guns (10cm HA), it helps with lowering the damage done by Flagship Wo kai during Air Strike phrase.
• A recommended composition is 4 DD, 1 CL and 1 CV. Equip your CV with anti-air fighters and the rest of your fleet with ASW. Do not equip your fleet with recon planes.

E-5 - North Pacific Sea - Capture Wake 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 with submarine(s).
• 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)

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.
  • This composition will always send you to the southern preboss node.
• 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) as well.
• Equipment for battleships : Two 46cm, recon plane, Type 3 Shell (you will need type 3 to deal with the boss).
• Choose line ahead in boss node to for the 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.
• 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.
