Battle Opening Breakdown

Battle Opening is one of the daytime combat intermediary phases, taking place immediately before the First shelling starts. In this phase, allied and enemy fleets launch attacks with the intent to disable or remove enemy targets before the combat proper starts. This grants either fleet substantial advantages by possibly disabling key ships on the opposing side.

Battle Opening has the following structure:

  • Opening ASW Shelling (OASW)
  • Opening Torpedo Salvo

In case neither fleets meet the requirements, the sub-phase will be skipped.

Opening ASW Shelling (OASW)

Commonly referred to as OASW (opening ASW). All eligible ships will perform a regular ASW Shelling attack, following range order in the same fashion as the First Shelling Phase. As these opening attacks happen before the Opening Torpedo Salvo, they may disable or even sink enemy submarines before they have a chance to attack.

OASW has the following trigger conditions:

  • Only ships listed below can trigger an OASW,
    • The ship is not required to be able to perform any ASW Shelling.
  • They must meet their specific ASW stat threshold and requirements, listed below,
OASW Ship ASW Stat Required[1] Equipment Required[2][3][4]
Any DD, CL, CLT, CT, AO[5] 100+ ASW   1 Sonar Equipped

  		  +  Bomber /   /   /

  1. ↑ The Required ASW Stat does include Visible Bonuses, but does not include Improvements.
  2. ↑ Visible Bonuses or Improvements do not count as equipment ASW (e.g. a +6 ASW equipment with +1 ASW bonus does not count as a +7 equipment but just as a +6 one).
  3. ↑ When applicable, if all relevant ASW aircraft are in zero plane slots, and no bomber  /  with 1+   are present in non-zero plane slot, the ship cannot OASW.
  4. ↑ Regardless of their ASW stat,    Fighters or   Carrier Recons cannot trigger any OASW.
  5. ↑ Other ASW Shelling capable ships may be able to OASW, but cannot reach 100 ASW   using currently available equipment.
  6. ↑ CVE should be used, as they are the only CVL with base ASW   stat.
  7. ↑ Kai only for Heywood L. Edwards.

See the list of Anti-submarine Weaponry and ASW Aircraft to better see what can help achieve OASW on a given ship.

Abyssals

Abyssal ships do not follow these rules. The following may perform OASW unconditionally:

Other abyssals cannot perform OASW.

Opening Torpedo Salvo

Commonly referred to as oTorp (opening torpedo). Eligible ships will fire an Opening Torpedo attack. This attack behaves similarly to the Closing Torpedo attack, with the difference that it will be launched regardless of the ship's damage state.

Opening Torpedo salvo has the following trigger conditions:

This phase follows the same rules as Closing Torpedo Salvo, with some exceptions:

  • Ships at Moderate or Heavy damage can still fire torpedoes.
  • If only submarines are left in the opposing fleet, torpedoes will randomly target them, never dealing damage, and always being displayed as "miss".

After the Opening Torpedo Salvo, the Day Battle Shelling starts (if there are any remaining ships on either side left).

Atoll Nodes

Uniquely on "Atoll Nodes", it is possibly to deploy the   Ka-Tsu tanks 
  to trigger a special Opening Torpedo Salvo.

  • On those nodes, regular oTorp will not work,
  • This can only be deployed by SS, SSV, and the AV Mikuma Kai Ni Toku, Nisshin A, and Mizuho Kai fast,
    • They must carry at least one Ka-Tsu tank,
  • On the "atoll node", ships meeting those requirements will carry out a special opening torpedo attack,
  • In night battle, those ships will additionally trigger the same attack as a cutin,
    • This attack overrides regular Night Cut-ins attacks (e.g. if a ship is setuped for a TCI, it will still trigger the Ka-Tsu attack).
  • Using several Ka-Tsu tanks on a same ship will make it carry out several of those attacks in a row (day and night),
    • It capped at 2 attacks per ship at night.
    • This attack utilizes a new special animation, with the tank climbing the atoll's soil.
