Moderniztion intro01.jpg

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

  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, click the Begin Synthesis!! (合成開始!!) button to modernize.
    • The button will be greyed out if the ship girl cannot be modernized any further.

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.
    • For ASW, it is +9.
  • Locking ship girls will prevent them from showing up as modernization fodder.

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} &= \text{Stat}_\text{input} + \lfloor \frac{\text{Stat}_\text{input} +1}{5} \rfloor \\ \text{Stat}_\text{failure} &= \lfloor 0.5 \times \left( \text{Stat}_\text{input} + \frac{\text{Stat}_\text{input} +2}{5} \right) \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
  • Using 4 DE will count as 2 pairs,
  • Using 3 or 5 DE with count as 1 or 2 pairs, and a single ship.

Luck Modernization

Luck can be modernized either by using Maruyu or DEs. Remember that luck modernization is not reset on remodel.

Notes
  • Modernization success is guaranteed if using 5 Maruyu.
    • This is why it is very important to remodel her to Kai before using her as modernization fodder.
  • Maruyu is the easiest and most efficient method to modernize luck. It is highly advised to save DEs to modernize HP.

Maruyu

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

Coastal Defense (DE)

DEs have about a 50/50 chance of granting +1 luck when used alone or in pairs. The pair must be two different ship girls from the same class.

  • +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.
    • There is a small chance (~6-7%) for an extra +1 luck if the pair is "at Kai level".
    • 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.

Pumpkins

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

  • See here for more details.

ASW Modernization

ASW increase is capped at +9. Currently, DEs are the only way to modernize ASW.

  • Modernization is only possible for ships that already have some base ASW stats.
  • 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 single or a pairs of DE that are not different DE of a same class will guarante +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 ASW.

The ASW mod success rate compared to the Luck mode is approximately as follows [1]:

  • For single DE:
[math]\displaystyle{ \text{ASWmod}_\text{Rate}\text{%} = 100 - \text{LUCKmod}_\text{Rate}\text{%} }[/math]
  • For DE pairs:
[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.
  • [math]\displaystyle{ \text{LUCKmod}_\text{Rate} }[/math] the luck modding rate from the above formula.
  • Notably :
    • If the total level of both DE is around 80+ (e.g. each of them lv 40+), the rate is about 20-30 %.
    • Using two DE pairs with a level total at 180+ has a chance of +2 ASW.

HP Modernization

HP can be increased by using DEs, Mizuho, or Kamoi. DEs must be used in pairs of two different ship girls from the same class to get +1 HP. Mizuho or Kamoi must be used in pairs to trigger HP modding.

For unmarried ships, HP can always be increased by a maximum of 2 points. Exceptions for married ships are:


Using pairs of different DE from the same class will guarante +1 HP 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]:
[math]\displaystyle{ \text{HPmod}_\text{Rate}\text{%} = 30 + 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% [3][4].


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

  • Mizuho: Mizuho and Kamoi.
  • Kamoi: Mizuho, Kamoi, Agano-class, and Yamato-class.
  • Kamoi and Mizuho are not interchangeable.
  • The success rate for modernization using AV/AO (only Mizuho or Kamoi) can be increased by adding more duplicates.
    • +30% per base AV/AO
    • +40% per Kai AV/AO
    • If the success rate goes over 100%, a roll for a second HP increase is performed. E.g. 120% = 20% chance for +2HP.
