The Attack on Pearl Harbor

On December 7th, 1941, the Japanese would commence with a full carrier attack against the United State's naval forces stationed at Pearl Harbor with the intent and goal to knock out many of the main ships and forces located in the area and to attempt to delay the Americans from launching a possible counter attack while they attempted to gain control of the Philippines later on in hopes of maintaining a route to transport oil back to thier country. On this day, the Kido Butai would launch massive air strike damaging many facilities in the Pearl Harbor front and incapacitating and sink many large ships include a large number of battleships, and various cruisers. This would would mark the beginning of Japan's War against the United States and would be known as the "date that would live on in infamy".

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), Operation C (丙, Easy) or Operation D (丁, Very Easy) .
   • Choosing A or B requires certain HQ Level (HQ Lv 35 for B / 80 for A in Spring 2015 Event).
   • An important note to all Admirals intending to clear the event on Hard difficulty - further (new) conditions now apply:
     • When switching difficulty from any other difficulty to Hard, the map's debuff mechanism (where applicable) will be reset.
       • Switching between any other difficulties will not reset the debuff mechanism.
2. The debuff system from Summer 2015 Event's final map, where certain nodes had to be killed to reduce boss armor will return.
3. It might be possible, that they will allow a fleet with seven ships (Striking Force Fleet) to sortie to certain event maps that allow single fleet operations starting from E-2, and also includes the final map of the event.
   • The Striking Force cannot be sortied during exercises or sent on expeditions while it contains seven ships.
   • The Striking Force can only be created and used in the third fleet in the menu (out of a total of four fleets).
   • A Striking Force with a flagship that carries a new piece of equipment, the Striking Force Fleet Command Facility, will be able to make use of the new Single Ship Evacuation mechanic.
     • The new Single Ship Evacuation mechanic that will become available for the Striking Force as of E-4 allowing a single ship in the fleet to retreat from the battlefield after an enemy engagement if she suffered heavy damage.
       • It is possible for the damage to become even worse during a Single Ship Evacuation.
       • Unlike the Combined Fleet's evacuation mechanic, it does not require an escort destroyer.
     • The new Striking Force Fleet Command Facility will become obtainable and useable via the old Fleet Command Facility and the Action Report that can be earned in the upcoming Fall Event. The Fleet Command Facility, as well as the new Action Report item, will be obtainable on all difficulty levels, including Medium and Easy Mode.
     • Supplementary information regarding the new Striking Force Fleet Command Facility and the Single Ship Evacuation it allows when carried by the striking force's flagship:
       • The evacuation does not require an escort destroyer.
       • The evacuation consumes the ship's entire fuel & ammo reserves.
       • Only one ship can be evacuated per battle.
       • The damage the ship suffered may become worse during the evacuation, but she will never sink.
4. Returning this event, the Vanguard Formation can be used .
   • This formation will organize the fleet such that the 3rd-6th/7th ships protect the Flagship and 2nd Ship of the Fleet.
     • In addition, the formation allows for ships to become more evasive in combat situations, especially with well-trained Destroyer.
     • This formation is also available only during the duration of the event.
     • The formation will be usable by both normal fleets as well as the Striking Force Fleet.
5. New: NPC Friend Fleets have been introduced into the game.
   • Friend Fleets act as another unit that appears in particular battles to help aid your fleet when attacking the enemy at the start of night battle.
     • NPC Friend Fleets are selected from a randomized preset list of ship.
     • Depending on who you have in your fleet can also influence who will be arrive to aid you in battle.
6. New: Enemy Radar Ambush Nodes is introduced into the game.
   • Entering this node will result in your fleet facing off against an enemy fleet that will ambush and attack your fleet
     • Your Fleet will not be able to fight against the enemy Fleet.
     • By meeting certain conditions, you can evade these nodes.
