Modernization is used to increase the Stats of a given ship, namely, the firepower Firepower, torpedo Torpedo Attack, anti-air Anti-Air, armor Armor, HP Health, ASW Anti-Submarine Warfare, and Luck Luck. 1 to 5 other ship girls are required in order to perform a Modernization.

  • This page is about the Modernization mechanic. Please see Remodel (Menu) for information about the UI.

How To Modernize

 
Modernization selection. Here Amatsukaze has 3 stars of modernization and her armor is maxed.
 
The Failure box ("Penguin") shown for failled modernizations.
  1. Click the Select (選択) button in the empty modernization slot to bring up a list of non-locked ship girls sorted by level.
  2. Select a ship girl to be placed in a modernization slot.
  3. Stats that will be improved will turn blue and show the potential maximum improvement.
    • HP, ASW, and Luck will just display a blue up arrow.
  4. Once the selection is made, to modernize, click on either:
    1. The Modernization Start (after disarming)!! button (blue, left), to modernize while disarming and saving any equipment currently equipped on the consumed girls,
    2. The Modernization Start!! (合成開始!!) button (green, right), to modernize while also losing any equipment currently equipped on the consumed girls.
    • The buttons will be greyed out if the ship girl cannot be modernized any further with the currently used ships.
  • If the modernization fails, the "failure box" (penguin) will be displayed.

Overview

  • Modernization upgrades for firepower, torpedo, AA, and armor are reset upon remodeling.
    • HP, ASW, and luck modernization upgrades are carried over.
  • Equipment on a ship girl used for modernization will be lost.
    • Remember to remove valuable equipment before using a ship girl as modernization fodder.
  • Stats cannot be increased beyond certain caps.
    • For firepower, torpedo, AA, armor, and luck; it is dependent on the ship girl and its remodels. Please see the individual ship girl pages or Ship Maximum Status for the caps.
    • For HP, it is +2, and may be capped lower after marriage HP gains;
    • For ASW, it is +9 for ships with a base ASW stat, 0 otherwise.
  • Locking ship girls will prevent them from showing up as modernization fodder.

When a ship get modernized, its "modernization level" increases, being represented by stars  , from 1 to 5.

  • Once fully modernized in firepower, torpedo, AA, and armor, the   "Max Modernized Star" will be displayed next to her level.

General Modernization

This applies to firepower  , torpedo  , anti-air  , and armor  . The formula for bonus stats from Modernization to these stats is:

Modernization Stat Formula
[math]\displaystyle{ \begin{align} \text{Stat}_\text{success} &= \bigg\lfloor \text{Stat}_\text{input} + \frac{\text{Stat}_\text{input} +1}{5} \bigg\rfloor \\ \text{Stat}_\text{failure} &= \bigg\lfloor 0.5 \times \left( \text{Stat}_\text{input} + \frac{\text{Stat}_\text{input} +2}{5} \right) \bigg\rfloor \end{align} }[/math]
With
  • [math]\displaystyle{ \text{Stat}_\text{input} }[/math] the stat increase displayed on the Modernization menu.
Notes
  • There is a fixed 50/50 chance of success/failure.
  • Success/failure is calculated independently per stat.
    • This means that it is possible for one stat to succeed and another to fail.
  • Successes are capped by the cap of the respective stat.
    • This can change the modernization efficiency listed below.
  • For maximum gains, it is better to spam multiple +5 modernizations.

Special Modernizations

When using certain ships, it is additionally possible to modernize HP  , ASW  , and Luck  .

Notes
  • It is unclear if using more than 2 DE is taken into account. If it is, the speculated working is:
    • Using 4 DE will count as 2 pairs,
    • Using 3 or 5 DE with count as 1 or 2 pairs, and a single ship.

Stats

Luck Modernization

Luck   can be modernized either by using:

Luck modernization is kept on remodel.

  • The luck cap is arbitrary for each ship remodel, and is usually very high.

Marriage also gives some luck.

HP Modernization

HP   can be modernized either by using:

HP modernization is kept on remodel.

  • The HP cap is arbitrary for each ship remodel, but the HP modernization is capped at +2 for unmarried ships, and between 0 and 2 for married ones.

Marriage also gives some HP, and will interfere with HP modernization for the following ships:

ASW Modernization

ASW   can be modernized by using Coastal Defense Ships (see here).

  • Modernization is only possible for ships that already have some base ASW stats.

ASW modernization is kept on remodel.

  • The ASW cap is +9 for all ships.
  • For certain ship changing type on remodel, this can have undesired effects (see here).

Maruyu

Maruyu can be used to increase the Luck of all ships.

  • Her base remodel will provide +1.2 luck while her Kai remodel provides +1.6 luck. Refer to the chart below for Modernization results:

Notes
  • +8 luck modernization is guaranteed when using 5 Maruyu Kai.
    • This is why it is very important to remodel her before using her as modernization fodder.

Pumpkins

It is possible to use the Pumpkins given during the Pumpkin Festival to increase luck during regular modernization.

  • By consuming 1 Pumpkin on a normal modernization, between 1 an 3 luck   will be added.
  • See here for more details.

Mizuho & Kamoi

Mizuho and Kamoi (AV/AO) can be used to increase the HP of certain ships:

  • Mizuho for Mizuho and Kamoi.
  • Kamoi for Mizuho, Kamoi, the Agano-class, and the Yamato-class.
  • Mizuho and Kamoi are not interchangeable.
  • Mizuho or Kamoi must be used in pairs to trigger HP modding.
    • Using their Kai+ remodels has greater effects.

The HP mod success rate compared to the Luck mode is as follows:

Mizuho & Kamoi HP Modding
[math]\displaystyle{ \text{HPmod}_\text{Rate}\text{%} = 30 \times \text{N}_\text{b} + 40 \times \text{N}_\text{K} }[/math]
With
  • [math]\displaystyle{ \text{N}_\text{b} }[/math] the number of AV/AO on base form,
  • [math]\displaystyle{ \text{N}_\text{K} }[/math] the number of AV/AO on Kai+ form.
Notes
  • If the success rate goes over 100%, a roll for a second HP increase is performed (e.g. 120% = 20% chance for +2HP).

Coastal Defense Ships (DE)

Coastal Defense Ships (DE) have a chance of granting:

  • +1 Luck   when used "alone or in pairs".
  • +1 HP   when used in "pairs of different ships from the same class".
  • +1 ASW   when used "alone or in pairs".

Luck


DE can give +1 Luck   when used alone or in pairs.

  • It will give +1 HP   or ASW   if it fails, depending of the situation.
  • For single DE [1]:
Single DE Luck Modding
[math]\displaystyle{ \text{LUCKmod}_\text{Rate}\text{%} = 32 + 0.7 \times \text{Lv} }[/math]
With
  • [math]\displaystyle{ \text{Lv} }[/math] the level of the DE used in the modding.
  • For DE pairs:
DE Pairs Luck Modding
[math]\displaystyle{ \text{LUCKmod}_\text{Rate}\text{%} = 100 - \text{X}_\text{Rate}\text{%} }[/math]
With
  • [math]\displaystyle{ \text{X}_\text{Rate}\text{%} }[/math] being either:
    • [math]\displaystyle{ \text{HPmod}_\text{Rate}\text{%} }[/math] for HP DE pairs,
    • [math]\displaystyle{ \text{ASWmod}_\text{Rate}\text{%} }[/math] for ASW DE pairs.

Notably:

  • +1 luck or HP is guaranteed from upgrades of pairs of different DE from a same class.
  • +1 luck or ASW is guaranteed from upgrades of single DE of any other pairing.
  • If the total level of 2 DE is around 80+ (e.g. each of them lv 40+), there is a small chance (~6-7%) for an extra +1 luck
    • In the case the ship cannot receive one of the 2 guaranteed stats (e.g. a BB for ASW) then there is a chance to fail the modernization.

It is highly advised to save DEs to modernize HP/ASW instead of luck.

HP


DE can give +1 HP   when used in "pairs of different ships from the same class".

  • It will give +1 Luck   if it fails .
  • If the ship is already at max HP, this will instead guarantee +1 ASW or +1 Luck.
  • It has been observed that, the higher the total level of two DEs used for modernization, the higher is the chance to get +1 HP.
  • The HP mod success rate compared to the Luck mode is approximately as follows [2][3]:
DE Pair HP Modding
[math]\displaystyle{ \text{HPmod}_\text{Rate}\text{%} = 26 + 0.35 \times \sum_\text{DE} \text{Lv} }[/math]
With
  • [math]\displaystyle{ \text{Lv} }[/math] the level of the DE used in the modding.
  • Notably:
    • If both DE are Lv 1, the rate is about 30 %,
    • If the total level of both DE is around 180+ (e.g. each of them lv 90+), the rate is about 90% [4][5].

ASW


DE can give +1 HP   when used "alone" or in pairs that are not "different ships from the same class".

  • It will give +1 Luck   if it fails .
  • Modernization will fail if the ship girl is at the ASW cap.
    • Modernization can still succeed if luck is rolled instead of ASW (if the ship girl is not at her luck cap).
  • Using "pairs of different DE from the same class" will also guarantee +1 ASW or +1 Luck if the ship is already at max HP.
  • It has been observed that, the higher the total level of two DEs used for modernization, the higher is the chance to get +1 ASW.

The ASW mod success rate compared to the Luck mode is approximately as follows[6]:

  • For single DE:
Single DE ASW Modding
[math]\displaystyle{ \text{ASWmod}_\text{Rate}\text{%} = 100 - \text{LUCKmod}_\text{Rate}\text{%} }[/math]
With
  • [math]\displaystyle{ \text{LUCKmod}_\text{Rate} }[/math] the luck modding rate from the above formula.
  • For DE pairs:
    • When pairs are used the ASW mod roll appears to be independant from the HP/luck roll.
DE Pairs ASW Modding
[math]\displaystyle{ \text{ASWmod}_\text{Rate}\text{%} = 10 + 0.40 \times \sum_\text{DE} \text{Lv} }[/math]
With
  • [math]\displaystyle{ \text{Lv} }[/math] the level of the DE used in the modding.
Notes
  • Due to low sampple size for high levels the formula may be inaccurate.
  • Notably:
    • When using multiple DE, ASW modding is only possible if the levels' sum is above 103 the rate is then about 60%.
    • Using two DE pairs with a level total at 180+ has a chance of +2 ASW.
