Introduction

The Summer 2015 Event "Counterattack! The Second Operation SN" is slated to start on August 10, 2015, and will last for about 20 days. The event will be based on Operation SN, the Japanese plan to establish air bases in the southern Solomon Islands; however, there was no actual second Operation SN historically.

This will be a large-scale event that will contain combined fleet operations and ship locking mechanics. There will also be a new system introduced into the game that will be equipment related.

Patch Notes

1. Summer Event 2015: "Counter attack! The 2nd SN operation" has started and will last for twenty days.

2. Main part of the "Counter attack! The 2nd SN operation" event consists of four maps: E-1 "Preparation, the 2nd SN Operation!" E-2 "Combined Fleet, to the Solomon Sea!" E-3 "Charge! The 2nd South Pacific Battles" E-4 "To the Strait! Destroy the Enemy Airfield!"

3. Clearing the main part will award you with the following new ships: Clearing E-2 will award DD "Kawakaze" Clearing E-4 will award seaplane-carrying oiler "Hayasui"

4. E-2 and E-3 requires Combined Fleet. The first fleet is the main and the second is the supporting fleet; you can drag the icon from 2 to 1 to create the Combined Fleet.

5. Item rewards 1/3 E-3 will award you with the new plane "Type 97 Torpedo Bomber (Murada squadron)"; finishing a quest will allow it to receive a plane upgrade.

6. Item rewards 2/3 Clearing the areas will award you with items and consumables including "Reinforcement Expansions", "Battle Rations", "On-Sea Resuppliers"

7. Item awards 3/3 Choosing different difficulties will reward different amounts of items: You can get "Type 97 Torpedo Bomber (Murada squadron)" on all difficulties.

Mechanics

Participation requirements

• Must have a 75% sortie win ratio.
• Must have 5 empty ship slots for new ships.
• Must have 20 free equipment slots.

Special Mechanics

1. The difficulty system first used in Spring 2015 Event returns: you can choose between Operation A (甲, Hard), Operation B (乙, Medium) or Operation C (丙, Easy).
   • Choosing A or B requires certain HQ Level (HQ Lv 35 for B / 80 for A in Spring 2015 Event).
   • With the exception of E-1, in order to choose Operation A, the previous map must be cleared on A or B.
2. A new system will be introduced with the release of this event involving carrier-based planes.

E-1

Preparation for Second Operation SN! 【発動準備、第二次SN作戦！】 Information Boss: (Kills required) 5 (All difficulties) At least 1 CL and 2 DD required. Ships tagged with BLUE tag Rewards upon clearance: Furniture Fairy Clearing on Hard (甲): Irako, 2x Reinforcement Expansions, 4x Combat Rations Clearing on Medium (乙): Irako, Reinforcement Expansions, 3x Combat Rations Clearing on Easy (丙): Reinforcement Expansions, 2x Combat Rations
Branching rules Show/Hide Branching Rules Branching Rules Node Split Condition A B SS in fleet, or random with D if no SS or CV C CV in fleet D Kikuzuki in fleet, or random with B if no SS or CV F If fleet doesn't pass LoS Check (higher priority than the rest)
Tips South route seems to have success with 2CL 4DD If going north, 1CL 2CVL 3DD seems to work. Note however that you go through a sub node and preboss has a Ri-class CA so this might not be worth the shiplocks. Since the tagging is shared with E-2, it may be worthwhile to use BBV / CAV / AV in the fleet, as the A - D - Z route has no enemy air power and this can guarantee air superiority.

Combined Fleet, to the Solomon Sea! 【連合艦隊、ソロモン海へ！】 Information Boss: (Kills required) Unryuu confirmed drop even on easy.

Tips Node B is a submarine node. Going south route with a Surface Task Force will conserve bauxite but cost more ammo and fuel. There is no aerial resistance. (1CVL should be more than enough) Reports say south route is much easier. 3BB 1BBV 1CA 1CVL + 1CL 1CLT 4DD seems to guarantee AEGDZ. Going north route with a Carrier Task Force will conserve a bit more fuel but has much higher bauxite costs. Reports say north route is much more difficult. There are three aerial battles. Nodes F and H have fs kai Wo-class with takoyakis.
