"Improvements" are increases in performance for equipment, being represented using Improved stars.

Improvements are notably done via "Akashi's Improvement Arsenal", requiring Akashi and Improvement Materials Improvement material, or may be already present on the equipment when obtained.

  • See how to perform improvements here.
  • See the full list of improvable equipment here (this omit the equipment not improvable but obtainable already improved) .
  • See the full list of ship Helpers here.

Overview

  1. Improvement levels are displayed beside equipment names.
    • They run from Improved+1 to Max-Improved (+10).
  2. Improvement bonuses are hidden. The increase in stats is not reflected on ship girls' stat cards.
    • This means they do not count for Support Expeditions or for reaching certain thresholds like for OASW.
    • Those bonuses work to some extent to reach regular Expeditions thresholds (see here).
    • Some improvements on equipment can also add some additional Visible Fit Bonuses.
      • This works on an equipment-to-equipment and ship-to-ship basis with no general rule.
  3. Most conversion quests (e.g. F62), allow to use improved equipment, but any Improved are lost during conversion.
  4. Certain conversion quests that do not require improved equipment, will carry over any Improved from the required equipment to the upgraded equipment.

Improvement Bonuses

The bonus stats gained from improvement will vary depending on the type of equipment as well as the stat itself.

  • Most improved stats will come as decimal numbers, due to how square roots work.
  • It is important to note that decimals must not be discarded in favor of whole numbers, as stats will be multiplied by various formulas anyway, to finally be rounded down/up.
  • For calculated improvement bonuses, please refer to the Categories Charts.

The improvement effects are unknown/unclear for some equipment types/cases.

Square Rooted Bonus

Most bonuses are all a function of the square root of the improvement level. The bonus can be calculated by:

[math]\displaystyle{ \text{Bonus}_\text{stat} = \sum_{\text{All equips}} \text{Mod}_\text{equip} \sqrt{\bigstar} }[/math]
With
  • [math]\displaystyle{ \bigstar }[/math] the improvement level of the equipment.
  • [math]\displaystyle{ \text{Mod}_\text{equip} }[/math] the equipment modifier for that stat, described below:
