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.

Notes
  • As Abyssals also follow those conditions, SS/V can be used as "Submarine Tanks" 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   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  Searchlights 
  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 Small Searchlight   Large Large 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  , 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 +3  at +9 ).

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.
Formation Flagship Protection SL Flagship Protection Notes
Small SL Large SL
Line Ahead   45% 13.74% 18.94%
Diamond   75% 22.90% 31.57%
Double Line   60% 18.32% 25.26%
Echelon   60%
Line Abreast   60%
Vanguard   Medium ? ? Upper half of the fleet
High ? ? Bottom half of the fleet
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

PT-Imp

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 Pack  & Schnellboot Imp Pack ) are "very small and fast".
  • All ship types suffer a severe   accuracy and   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].
Attack formula against PT boats
The Attack formula against PT boats:[2][3]
Jet Assault & Airstrike
  • [math]\displaystyle{ \text{Damage}_\text{PT}= \text{Atk}_\text{post-cap} \times \text{Rand} [0.5 ; 0.8] }[/math]


LBAS[4]
  • [math]\displaystyle{ \text{Damage}_\text{PT}= \text{Atk}_\text{post-cap} \times \text{Rand} [0.4 ; 0.7] }[/math]


Shelling
  • [math]\displaystyle{ \text{Damage}_\text{PT}= ( 0.3 \times \text{Atk}_\text{post-cap} + \sqrt{\text{Atk}_\text{post-cap}} + 10 ) \times \prod^{All Equipment}{\text{Mod}_\text{EquipmentAtk}} }[/math]


Opening & Closing Torpedo Salvos
  • [math]\displaystyle{ \text{Damage}_\text{PT}= 0.3 \times \text{Atk}_\text{post-cap} + \sqrt{\text{Atk}_\text{post-cap}} + 10 }[/math]


Night Battle
  • Night Battle data are unclear yet.


With
  • [math]\displaystyle{ \text{Atk}_\text{post-cap} }[/math] the post cap attack power defined here,
  • [math]\displaystyle{ \text{Mod}_\text{EquipmentAtk} }[/math] the bonuses given by equipment, described below.
Accuracy formula against PT boats
The Accuracy formula against PT boats:[5][6][7][8]
[math]\displaystyle{ \text{Hit Rate}_\text{vs.PT} \text{%} = \Big\lfloor ( 0.3 \times \text{Accuracy}_\text{Atk} + \sqrt{\text{Accuracy}_\text{Atk}} + 15 ) \times 1.2 \times \text{Mod}_\text{Ship} \times \Big( \prod^{All Equipment}{\text{Mod}_\text{EquipmentAcc}} \Big) \times \text{Mod}_\text{Night} \Big\rfloor - \text{EVA}_\text{PT} + 1 }[/math]
With
  • [math]\displaystyle{ \text{Acc}_\text{Atk} }[/math] the standard accuracy described here
    • PT boats are "DDs" in the game, so the [math]\displaystyle{ \text{Mod}_\text{formation} }[/math] for vanguard is 1.1 during shelling, and 1.2 during the torpedo phase.
    • Historical accuracy bonuses during Events are included in the Standard Accuracy Term, i.e. it is affected by the [math]\displaystyle{ \text{Mod}_\text{PT} }[/math] modifier.
  • [math]\displaystyle{ \text{EVA}_\text{PT} }[/math] the PT estimated evasion   described bellow,

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

  • DD placed in the composition slots above and below her will gain a noticeable accuracy boost and will prioritize attacking PT boats if any are present.
  • The PT boat targeting rate is 100% for all affected ships [9].

During Events, some special bonuses may be added, with "historical" ships and equipment gaining some accuracy bonuses[10].

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   Ka-Tsu Tanks 
          bonus does not stack with the   Armed Boats 
          ones.
  • Using other setups improving accuracy is also advisable:
