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.

Special Mechanics
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.
A new system will be introduced with the release of this event involving carrier-based planes.

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.
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.
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.
