Flagship Protection

Flagship Protection is when a non-flagship protects the flagship from being targeted by receiving the attack instead. When activated, a "curved shield" animation plays in front of the flagship's banner.

  • Activation rate is determined solely by the selected formation. If activated, a ship with HP above Minor Damage (小破) is randomly selected to be the protector.
    • If no ships are above Minor Damage, flagship protection cannot activate.
    • Having more ships above Minor Damage does not increase the rate.
  • It may activate on any type of attack, including shelling, torpedo, ASW, airstrike, and support.
  • Submarines do not protect surface ships and surface ships do not protect submarines.
  • Installations cannot perform protection, and cannot receive protection if they are flagship.
  • In Combined Fleets, the escort flagship does not receive flagship protection.

Submarines

Only certain ships meeting certain conditions can attack SS(V).

  • Most often, if a ship can attack a submarine, focusing it will take over any other target.

Here, Dive-bomber or Torpedo Bomber refers to any Dive Bomber/Torpedo Bomber.

Notes
  • As Abyssals also follow those conditions, SS/V can be used as "Submarine Tanks" (Sub-tanking) on some maps to deviate attacks from the fleet to the submarine.

Installations

Installations are immune to certain types of attacks:

Shelling

Submarines can only attack installations during the shelling if equipped with Amphibious Vehicle Special Amphibious Tanks.

  • They will only target installations during the shelling phases.
  • They will be able to attack installations at night regardless of equipment.
  • Their low firepower makes them poor anti-installation ships.

Carriers are unable to perform CVCI on installations, even if equipped with anti-installation dive bombers.

Special Attacks behave like normal against installation.

Torpedo

Both Opening Torpedo Salvos and Closing Torpedo Salvos cannot target installations.

  • Opening and closing torpedoes will fail to trigger if only installation targets remain.

Searchlights

The following table describes how SearchlightSearchlightsSearchlight
Type 96 150cm Searchlight actually work on the game side, assuming a night battle fleet with 6 ships.

  • When a ship is attacking, it will roll a random "regular target" like usual, and then:
    • If a searchlight is activated, the game will try additional rolls, to check whether the SL carrier(s) will be the new target or not.
      • The game treat whoever is carrying a SL as the SL carrier, thus increasing the chance of hitting the SL carrier as mentioned below (the process will stop as soon as the game "rolled an SL carrier", even if that girl's searchlight did not triggered).
    • If this attempt fails to roll that girl, it will repeat the roll again, up to two or three times, depending on the type of searchlight.
    • This process stops once it rolled the girl carrying the SL or after it failed all the attempts and accepts the regular target rolled in the last attempt as the girl to be aimed at.
Small SearchlightSmall Small SearchlightSearchlight Large SearchlightLarge Large SearchlightType 96 150cm Searchlight
Rolls 2 rolls are made at most 3 rolls are made at most
Scenario 1 Attempt 1:

The game rolls the SL carrier immediately: 1/6 chance = 16.67%

Scenario 2 Attempt 2:

The game fails the first attempt (rolled any other 5 ships instead, so 5/6 = 83.33%), but successfully the SL carrier on the second attempt (1/6 = 16.67%), meaning this scenario has 83.33% x 16.67% = 13.89% chance of happening.

Scenario 3 All attempts fail:

The game fails both attempts, meaning 5/6 x 5/6 = 69.44% chance that the SL carrier will NOT get aimed at.

Attempt 3:

The game fails the first two attempts (rolled any other 5 ships instead, so 5/6 x 5/6 = 69.44%), but successfully the SL carrier on the third attempt (1/6 = 16.69%), meaning this scenario has 69.44% x 16.67% = 11.57% chance of happening

Scenario 4 N/A All attempts failed:

The game fails both attempts, meaning 5/6 x 5/6 x 5/6 = 57.87% chance that the SL carrier will NOT get aimed at.

Results The SL carrier has 30.56%16.67% + 13.89% chance to get aimed at (69.44% of not getting aimed at). The SL carrier has 42.13%16.67% + 13.88% + 11.57% chance to get aimed at (57.87% of not getting aimed at).

Effect On the SL Carrier

All SL carriers get an 80% evasion penalty, regardless of searchlight activation (see evasion).

If the SL is improved Improved, the chance of the SL carrier getting hit increases (more likely to take damage).

  • Improved searchlight does not change the rate of "getting aimed at", it is still the base rate.
  • Improving SL reduces enemy CI rate even further while increasing the fleet CI so it is great to put some investment on this equipment.
  • Despite this, it is still recommended to improve SL as it offers firepower/yasen (up to +3Firepower at +9Improved).

If the fleet contains 2 girls or more carrying the small SL and large SL, the large SL takes priority.

  • If they carry the same type of SL, the priority follows ship order.

SL Flagship Protection

All the cases mentioned above assumed all the ships have an equal chance of getting aimed rate, ignoring #Flagship Protection.

  • If the SL carrier is the flagship, she will be shielded by the other ships in the fleet, thus reducing the chance of getting aimed at compared to the previously shown rates.

Combined Fleets Yes N/A Main
No Escort

In practical use, it is ill-advised to put a searchlight on the flagship, as flagship protection has an higher chance to trigger and so put at risk other ships

  • Do not that the ships shielding the flagship do not suffer the 80% evasion penalty, and so can still effectively agro and evade the shots.
  • Combined Fleets are unaffected by this issue as Flagship Protection does not apply in the escort.

Vanguard Formation

  • Vanguard is only available during Events, and is usable on any map during this time.
  • The modifiers on Vanguard Formation refer respectively to the "upper half" and "bottom half" of the fleet.
    • For a fleet with 6 or 7 ships, the top row applies to ships 1 to 3, and the bottom row applies to the remaining ships.
    • For a fleet with 4 or 5 ships, the top row applies to ships 1 and 2 and the bottom row applies to the remaining ships.
  • Attacks from support fleets are affected by the top row multipliers, meaning the 50% damage modifier is applied.
  • Vanguard gives an accuracy malus to the opposite fleet. See here for more details.
  • Bottom half ships have increased chance to be targeted.
    • The targeting is determined as follows:
      • 1. Randomly select any ship from the fleet.
      • 2. If the selected ship is an upper half ship, randomly select any ship from the fleet again.[1]
    • Target rate per ship (without flagship protection) based on the above procedure:
Number of Ships 4 5 6 7
Upper Half 12.5% 8% 8.33% 6.13%
Bottom Half 37.5% 28% 25% 20.4%

PT-Imp

Amagiri Kai Ni/DAmagiri Kai Ni
Amagiri Kai Ni D has the ability to prioritize focusing on attacking PT-Imp with significantly increased accuracy if any are present.

  • Ships placed in the composition slots above and below her will gain a noticeable accuracy boost and will prioritize attacking PT-Imp if any are present.
Anti-PT boat
Unlike most standard Abyssals, "PT boats" (PT Imp PackPT Imp Pack & Schnellboot Imp PackSchnellboot Imp Pack) are "very small and fast".
  • All ship types suffer a severe Accuracy accuracy and Firepower firepower penalty against PT boats.
  • Attacking them with larger guns is not very effective, smaller guns being recommended instead.
  • Support Expeditions are not affect by any of the following[1].

Notes
  • It is recommended to use anti-PT setups on DDs only, such setups compromising overall combat effectiveness.
  • Having a Reinforcement Expansion is important because it can save a ship slot by containing a machine gun or skilled lookouts.
  • Combining equipment is recommended to see significant boosts to accuracy.
  • The Amphibious Vehicle Ka-Tsu TanksSpecial Type 4 Amphibious Tank
    Special Type 4 Amphibious Tank Kai     bonus does not stack with the Landing Craft Armed BoatsSoukoutei (Armored Boat Class)
