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-1

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 4 drums on 2 ships (e.g. 3 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

E-2 Map

• Rewards a Medal and Construction Ship Akashi upon clear
• 150 exp
• Map gauge has 6 hp
• Node H is night battle
• Boss is BB Ru-Class Flagship Kai

Branching rules

• 2 BB, 1 CLT, 1 CAV, 2 CV with BB and CAV equiped 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 / affect it technically)

E-3 Map

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.
• 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 . 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.
• If 1 CV with 5DD (or 4DD 1CL), you 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, your ships are damaged or you get a poor engagement modifier, as no BB means no second attack for your ships.
• If 1 BB instead of 1 CV, you might want to consider using a BBV with your best seaplanes to enable ASW.
• 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. 
• 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 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.  
  • DD BB DD DD DD CL.  Equip BB with three main guns and a good surface radar.  BBV for anti-sub is not necessary on top of the second shelling phase for the DDs/CL.

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 more than 3 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, 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.
  • 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.
  • 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.
• 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.
