Gameplay Notes

Submarine Tenders (AS) are very weak, mostly used for certain Routings

Special Mechanics

Submarine Touch

She can trigger a Special Attack involving a Submarine Tender leading a fleet of at least two submarines.

  • The flagship must be a Submarine Tender (AS) at Lv 30+,
    • She must not be more than moderately damaged (中破).
  • The 2nd and 3rd ships must be Submarines (SS) or Aircraft Carrying Submarines (SSV) and not evacuated via   SFFCF ,
    • The 4th ship may optionally be a SS(V), but does not affect the above requirement,
    • At least two SS(V) among the 2nd, 3rd, and 4th ships must not be more than lightly damaged (小破),
    • If all 3 ships are SS(V), the 2nd and 4th ones will attack; if one of the two is moderately damaged (中破), the 3rd one will attack instead.[1]
  • The fleet must be a single fleet or a Striking Force Fleet,
  • The formation needs to be either Echelon  or Line Abreast ,
  • At least one Submarine Supply Material  must be available in the inventory.

  • Two SS(V) will launch torpedo strikes.
  • The attack power of each strike is postcapped and unaffected by formation, engagement, or damage cap.
  • A rough damage formula per Submarine attack is:
[math]\displaystyle{ \text{DMG}_\text{day} = \text{TP} \times ( 1.2 + 0.04 \times \sqrt{LV} ) }[/math]

[math]\displaystyle{ \text{DMG}_\text{night} = ( \text{FP + TP} ) \times ( 1.2 + 0.04 \times \sqrt{LV} ) }[/math]

With
  • [math]\displaystyle{ \text{DMG} }[/math] the damage result for day and night battle respectively,
  • [math]\displaystyle{ \text{FP} }[/math] the submarine's Firepower   stat,
  • [math]\displaystyle{ \text{TP} }[/math] the submarine's Torpedo   stat,
  • [math]\displaystyle{ \text{LV} }[/math] the submarine's Level.
    • [math]\displaystyle{ 1.2 + 0.04 \times \sqrt{LV} = 1.6 }[/math] at Lv 100.

The number of attacks per Touch ranges from 2 to 4.

  • Each submarine will trough either 1 or 2 torpedo strikes.
    • Only Lv 75+ submarines can trigger 2 strikes,
    • If a Lv 75+ submarine does not carry any   Submarine Radar, it rolls between 1 and 2 strikes randomly (exact rate unclear yet),
    • If a Lv 75+ submarine does carry any   Submarine Radar, it is guaranteed to roll 2 strikes.

One Submarine Supply Material  will be consumed for EACH battle the Touch triggers in.

  • If the Touch triggers twice in a battle, only a single   will be consumed for this battle.
  • If the Touch triggers in multiple nodes, one   will be consumed for each node it is triggered.
It does not consume any extra ammo. If the game is refreshed before the battle ends, then no material will be consumed even if the touch triggered.

Trigger rate is affected by the Level and luck   stat of the participating ships[1].

It has a chance to trigger every time the AS takes a turn at shelling.
  • It can trigger in both day and night for the same battle.
  • It can only trigger once during day battle.
  • If it fails to trigger during the day battle, there is still a chance to trigger it in the follow-up night battle.
  • If all enemies sunk, then touch stops early.
The attack order is always (where amo,g the attacking submarines, 1 is upper one and 2 is lower one):
  • 1-1-2-2 for 4 attacks,
  • 1-1-2 or 1-2-2 for 3 attacks,
  • 1-2 for 2 attacks.
    • If touch stops early, then attacks can be just 1-1
    • Also note that the actual order may be different from client animation of who shoots torpedoes, which always assigns attackers alternately like 1-2-1-2 or 1-2-1 or 1-2, so you may mismatch the real attack.
The touch can be activated multiple times per sortie.

When attacking a fleet, the usual Targeting rules apply.

  • The torpedoes fired target ships independently,
  • When facing a Combined Fleet, if any ship is present in the escort fleet on day battle, then all torpedoes will be fired to the escort fleet.

I am Heian Maru, the third of the Hikawa Maru-class ocean liners, as well as Heian Maru, the converted submarine tender. Yes, my older sister is the famed Hikawa Maru. I've heard she is still well-cared for in Yokohama in these gentler times. Admiral, please remember my contribution as her little sister, supporting the submarines operating out of Truk.
氷川丸級貨客船三番船平安丸改め、特設潜水母艦平安丸です。ええ、姉はあの氷川丸。この優しい時代にも横浜の地にその姿が健在と聞いています。提督、潜水母艦となった氷川丸の妹、トラックの地で潜水艦たちの作戦を支えた私の事も、どうか覚えておいてくださいましね。

Oh? What is it? Oh my, Admiral! Is something the matter? Eh, something on my skirt? Oh silly me, my apologies. Thank you, Admiral. However, that area happens to be my torpedo hold. If it is treated too carelessly... yes, it's quite dangerous.
あら?なんでしょう? あら、提督!どうかなさいましたか? え?スカートにゴミが? 私としたことが、失礼いたしました。提督ありがとうございます。あと、そのあたりは魚雷保管庫になります。あまり不用意に触られますと…はい、危険です。
Idle
Play
Indeed. I would be lying if I said I don't miss my days as an ocean liner. However, my time in Truk in the South Pacific was not bad either. I.. did not dislike my time taking care of the submarines there.
そうですね。貨客船時代が懐かしくないかと問われれば、いいえと言えば嘘になりましょう。でも、南洋トラックも悪いところではありませんでした。潜水艦たちのお世話は嫌いではありません。

Admiral, you must be tired. I've gone ahead and made you some black tea. I added a little bit of honey and brandy. Please take a little break to warm up. That's another important part... of your job. Here, please.
