Map Overview

E1 is a single/striking fleet, single-phase map consisting of route unlocks & one boss phase.

• 2 LBAS are available on this map:
  • Only 1 can be set on Sortie, the other being limited to Defense,
• This map uses 2 locks:
  • 104th Squadron, Starting point 1 (reused in E-3)
  • 1st Fleet, Starting point 2 (reused in E-2)

The use of AGDP AGDP on CV(B/L), Ise-class Kai Ni, Akitsu Maru Kai, Kumano Maru, Shimane Maru, and Yamashio Maru, is required to sortie these ships on the map.

• Node C2 is a resource node.
• Barrage Balloons can be deployed on node O

Fleet Notes
C2 is a resource node, therefore, it is possible to continue even when taiha on node C1. For the gimmick, sortie with a single submarine equipped with a Damage Control will guarantee to reach the end node. The route will not consume the material when the node is reached, even if the submarine is taiha. The 1 SS Fleet will route to 1 extra node at B1 before going to B2 The sub does not have to be fast. A slow sub is sufficient to route to C2 Else: Bringing AACI is advised to reach it. This comp can also be used to farm for fuel.
LBAS Notes
LBAS can be sent on the pre-node to eliminate any threat

Fleet Notes
Shortest route Using OASW are recommended. 1 ship equipped with AACI is recommended for D3. Avoiding D1 needs 5 ships MAX. Avoiding D2 needs either 0 DE (Fast) or 3+ DE (Slow). Therefore, the two major options are 1 CL/CT 3-4 DD Fast, or 1 CL/CT/CVL 0-1 DD 3-4 DE Slow.
LBAS Notes
ASW LBAS should be used on E.

Fleet Notes
Shortest route. The last node is surface battle one, so ASW is only advised to reach it, but not defeat it. Alternatively using Vanguard formation across nodes D E can help the fleet survive the sub nodes as they focus on surface combat. 1 ship equipped with AACI is recommended for D3

Fleet Notes
Do not deploy this fleet unless in possession of a large supply of duplicate battleships to lock, or playing in casual/easy for the rest of the event. Only consider as a possibility to run upon clearing the entire event when locks are no longer restricted. It is very powerful but very resource-intensive.

LBAS Notes
Sending all LBAS to the boss is advised, else, sending them to node M is viable to increase the reach rate.

AGDP is required for all carriers.

M includes the new Destroyer Ra-Class α, which possesses Opening Torpedoes and has good combat strength.

• Smokes are highly recommended for M along with Vanguard formation to avoid taking damage.

Boss fleet consists of the new Transport Ship Wa-Class B (Landing) Elite, which has high AA strength and is armed with a Barrage Balloon, to counter damage from carriers and LBAS.

• Be advised that if a land base is sent to O, planes and rank loss will be significantly higher.
  • It is therefore recommended to bring several Barrage Balloons in order to both mitigate these and buff allied aircraft damage.
• Using Boss support is recommended.
• The Wa-class, which has high HP but lacks strong armor, is possible to defeat using double attacks.

Trivia

• Starting point 1 is in the area of Aomori.
• The airfield is the Misawa Air Base, which is known in Japan and among USAF units assigned there as the "Tip of the Spear as it is the Northernmost air base from Tokyo. This is also the same airbase where the practice drills for the attack on Pearl Harbor took place.
• Starting point 2 is off the coast of the Iwate Prefecture.
• Node C2 is on the area between Shiranuka and Kushiro.
• The Boss node O is between the island of Kunashiri and the coast of Shibetsu. Kunashiri is a probable staging point for the Northern invasion of Japan and the main battle area if the war had dragged on as the Soviets took over Kunashiri and several Kurile Islands before the official surrender of Japan.
