Submarines

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

• Here, refers to any /

Ship	Conditions		Day Battle	Night Battle
	Stats	Equipment
Taiyou-class Kai Ni Kaga Kai Ni Go	Not more than moderately damaged (中破)	with 1+	Prioritize SS	Nigth Air Attack will prioritize surface target Nigth Shelling prioritize SS
Gambier Bay Mk.II				Prioritize SS (with a special night air attack)
All other CVL				Do not attack SS
Mogami-class Kou Kai Ni			Prioritize surface target
BBV, CAV, AV, LHA	None	Bomber, , , with 1+	Prioritize SS
Fusou-class Kai Ni		Same as other BBV with also
Hayasui Kai Yamashio Maru Kai		Equiped with
		Not equiped with	Prioritize SS
All other ships	At least 1 base ASW	None
	No base ASW		Do not attack SS

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.

• Ise-class Kai Ni can still perform the Suisei-CI against installations.

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

Searchlight Behavior

How searchlight actually works: Okay, assuming a night battle fleet with 6 ships. If the searchlight was activated, the game will attempt to roll the target to check whether that target is the girl carrying the searchlight (SL). If this attempt failed to roll that girl, it will repeat the roll again up to two or three attempts total, depends on the type of the searchlight. The process will stop once it rolled the girl carrying the SL OR once it failed all the attempts and accept the target rolled in the last attempt as the girl to be aimed at.

Normal SL

• For this type, the game will roll only twice at most.
• So what is the rate of the girl carrying SL will get aimed? Lets take a look of all the scenarios:
  • Scenario 1. Attempt 1: The game will roll her immediately, thats 1/6 chance = 16.66%
  • Scenario 2. Attempt 2: The game will fail the first attempt (Rolled 5 other ships instead of that girl, so 5/6 = 83.33%), but will successfully roll her on the second attempt (1/6 = 16.66%), that means this scenario has 83.33% x 16.66% = 13.88% chance of happening
  • Scenario 3. All attempts failed: The game will fail both attempts, meaning 5/6 x 5/6 = 69.44% chance that she will NOT get aimed at
• We can see above to draw the following conclusion:
  • The girl carrying SL has 16.66% + 13.88% = 30.54% chance of getting aimed at
  • 69.44% that she will NOT get aimed at

T96 Big SL

• For this type, the game will roll only thrice at most.
• So what is the rate of the girl carrying SL will get aimed? Lets take a look of all the scenarios:
  • Scenario 1. Attempt 1: The game will roll her immediately, thats 1/6 chance = 16.66%
  • Scenario 2. Attempt 2: The game will fail the first attempt (Rolled 5 other ships instead of that girl, so 5/6 = 83.33%), but will successfully roll her on the second attempt (1/6 = 16.66%), that means this scenario has 83.33% x 16.66% = 13.88% chance of happening
  • Scenario 3. Attempt 3: The game will fail the first two attempts (Rolled 5 other ships instead of that girl twice, so 5/6 x 5/6 = 69.44%), but will successfully roll her on the third attempt (1/6 = 16.66%), that means this scenario has 69.44% x 16.66% = 11.56% chance of happening
  • Scenario 4. All attempts failed: The game will fail all attempts, meaning 5/6 x 5/6 x 5/6 = 57.87% chance that she will NOT get aimed at
• We can see above to draw the following conclusion:
  • The girl carrying SL has 16.66% + 13.88% + 11.56% = 42.1% chance of getting aimed at
  • 57.87% that she will NOT get aimed at

Effect of the SL on the girl

• Whoever carried it will get -80% evasion (0.2x modifier stacked on her effective evasion). If the said SL is +max, the chance of her getting HIT increases (More likely to take damage)
  • On the same note, +max searchlight doesn't change the rate of getting AIMED at, it's still the same as base one.
• If the fleet contains 2 girls or more carrying the SL and T96 SL, the T96 SL will take priority. If they carry the same type of SL, the higher-order girl will take priority, as in ship 1 being the highest order, followed by 2, 3 and so on....
• Notice one important thing in the above point: All the girls carrying the SL will get -80% evasion regardless of her searchlight being activated or not
  • On the same note, the game will also treat whoever carrying the SL as the SL target, thus increasing the chance of hitting the SL girls as mentioned above (The process will stop as long as the game rolled the girl carrying SL, even if that girl's searchlight never activated before)

• Despite the increased getting hit rate, it's still recommended to max the SL because it offers +3 firepower. It's also suggested that improved SL reduces enemy CI even further while increasing our side CI so it's great to put some investment on this equipment

Flagship protection shielding the girl holding the SL

So far, all the cases mentioned above assumed all the ships have equal getting aimed rate, meaning the flagship position wasn't considered. If we consider the flagship protection too, we can have a more interesting result where the girl carrying the SL in flagship will be shielded by the other ships in the fleet, thus reducing the chance of getting aimed at.

• Line Ahead has 45% FS protection, the rate of triggering the shield are 13.74% (Normal) and 18.94% (Big SL)
• Diamond has 75% FS protection, the rate of triggering the shield are 22.90% (Normal) and 31.57% (Big SL)
• Double Line, Echelon and Line Abreast has 60% FS protection, the rate of triggering the shield are 18.32% (Normal) and 25.26% (Big SL)

(CF4 and CF2 in combined fleet might be equivalent to Line Ahead and Double Line respectively, but no data proved this yet, take this claim with a grain of salt)

In practical use, especially during event, it's ill-advised to put searchlight on FS due to the potential of triggering this shield where the other girls could have stood alone and shot the enemies instead of taking bullets for the flagship and wasting a shot.
