"Special Attacks", or "Touch", are special combats mechanics involving specific ships combinations in a fleet, in order to trigger a powerful attack, involving a unique animation and sometimes a unique "Touch CG" for the involved ships.

There are 3 main types of Touch currently in the game:

The "Big Seven Touches", the "Yamato Touch", the "French Touch", the "Queen Elizabeth-class Touch", some 2/3-battleships, 3-hits attacks.
The "Kongou Touch", a 2-battleships, 2-hits night attack.
The "Submarine Touch", a 1-submarine tender & 2/3-submarine, 2/4-hits torpedo attack

In a Combined Fleet, it is possible to both:

Trigger a Big Seven or Yamato Touch in the main fleet during day battle,
Then trigger a Kongou Touch in the escort fleet during night battle.

No special attack can be triggered in PVP.

Big Seven Touch

"Big Seven" refers to the first 7 battleships built to carry the biggest naval guns (> 40 cm) allowed by the Washington Naval Treaty, namely, the Nagato-class, Nelson-class, and Colorado-class.

Nagato-class Special Attack

At Kai Ni, Nagato and Mutsu gain a special attack:

"Touch Helpers"
Any FBB, BB, BBV

A Nagato-class Kai Ni must be the flagship.
- Secretary for combined fleets.
- She must not be more than lightly damaged (小破).
The 2nd ship in the fleet must be FBB/BB/BBV.
- She must not be heavily damaged (大破).

There must be 6 or more surface ships in the fleet.
- There must be no submarine in 6-ship fleets. In 7-ship fleets, only 1 submarine is allowed.
- There must be no surface ship in the fleet sunk or evacuated via FCF
  during a sortie, making the remaining total < 6. Ships in the escort fleet are not counted.

In single fleet, Echelon needs to be selected.
In a combined fleet, Cruising Formation 2 needs to be selected.

Bug: The attack cannot trigger in CTF versus a single fleet.

If triggered:

The flagship will do a 1st & 2nd attack,
The 2nd battleship will do a 3rd attack,
Each attack targets a ship at random,
If all enemies sunk, then touch stops early.

Can only be activated once per sortie.
Has a chance to trigger every time the flagship takes a turn at shelling.
- In single fleet, if it fails to trigger in day battle, there is a chance to trigger it in the follow-up night battle.
The rate is ^[1]:

- Only ships equipped with those equipment will get a bonus for their attack(s).

The attack will consume extra ammo from participating ships when triggered. The total ammo consumption will be x1.8 of the original ammo consumption of those ships when the attack is triggered.

The touch:

Can be triggered even if artillery spotting fails to activate.
Can only be activated once per sortie.
Has a chance to trigger every time the flagship takes a turn at shelling.
- In single fleet, if it fails to trigger in day battle, there is a chance to trigger it in the follow-up night battle.
The rate is probably:

[math]\displaystyle{ \text{Trigger}_\text{Rate}\text{%} = \Biggl\lfloor \text{V} \times \sum_\text{Ships} \sqrt{\text{Lv}} + \text{W} \times \sum_\text{Ships} \sqrt{\text{Luck}} + \text{X} + \text{Y} \Biggr\rfloor }[/math]

With

[math]\displaystyle{ \text{Lv} }[/math] the Level of the participating ships,
[math]\displaystyle{ \text{Luck} }[/math] the Luck of the participating ships,
[math]\displaystyle{ \text{V & W} }[/math] some yet unknown bonus factors,
[math]\displaystyle{ \text{X} }[/math] some yet unknown bonus variables,
[math]\displaystyle{ \text{Y} }[/math] some yet unknown base rate.

It is notably affected by:

The Level and luck stat of the participating ships,
Surface Radars (5+ LoS?) on attacking ships (+8~10 %)^[1].

It is currently measured above 70 %.

Kongou-class Touch

On Kai Ni B/C, the Kongou-class gains a special attack called "Night Assault":

A Kongou-class Kai Ni B/C must be flagship.
- Flagship of the 2nd fleet in combined fleets.
Another "Touch Helper" must be in the 2nd position.
Both must not be more than lightly damaged (小破).
It must be a Night Battle.

There must be 5 or more surface ships in the fleet.
- There must be no more than 1 submarine in 6-ship fleets. In 7-ship fleets, only 2 submarines are allowed.
- There must be no more than 1 surface ship in the fleet sunk or evacuated via FCF
  during a sortie, making the remaining total < 5. Only ships in the escort fleet are counted for combined ones.

In single fleet, Line Ahead or Echelon need to be selected.
In a combined fleet, Cruising Formation 2 or Cruising Formation 4 need to be selected.
- In a combined fleet, it can only be triggered in the Escort fleet.

"Touch Helpers"
Kongou Flagship:	Hiei Flagship:	Haruna Flagship:	Kirishima Flagship:
Any other Kongou-class Kai Ni B/C
Kai Ni Base/Kai Base/Kai	Kai Ni	-

If triggered:

The flagship will do a 1st attack,
The 2nd battleship will do a 2nd attack,
Each attack targets a ship at random,
If all enemies sunk, then touch stops early.

2+	2.210.8 x 2.4 x 1.15	2.762.4 x 1.15	3.451.25 x 2.4 x 1.15

Despite several devs' announcements, other equipment surch as the 35.6cm Twin Gun Mount Kai 2 and "advance Radars" do not provide any bonus to the touch [7].

The modifiers are pre-cap.
There is also an Accuracy bonus of 1.35~1.4 [8].

The attack will consume extra ammo from both participating battleships when triggered. The total ammo consumption will be x1.2 of the original ammo consumption of those ships when the attack is triggered, hence:
- If it is triggered in a night battle in a normal node, it costs 6 % extra ammo.
- If it is triggered in a night battle node, it costs 2 % extra ammo.

The Night Assault can be:

Activated in the same battle as another separate special attack.
Activated twice per sortie, during night battle only:^[1]^[2]^[3]^[4]^[5]

Submarine Special Attack

Also called the "AS Touch", it is 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.

↑ [9]

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].

Submarine Radars affect the trigger rate, each increasing the trigger rate by about 10 %^[2].

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.

↑ [10][11]

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.
