Equipment improvement levels are displayed beside equipment names, starting from ★+1 and up to ★+10 (★+max), they can be gained for certain equipment through Akashi's Improvement Arsenal, and give hidden stat bonuses to a user ship, depending on the equipment and their levels.
Effects[]
- There are no visible stat differences between non-improved and improved equipment.
- Improvements have been shown (or officially announced) to give additive bonuses to the following stats: day battle firepower (shelling) and torpedo (salvos), night battle power (firepower + torpedo), ASW, AA, eLoS, accuracy and torpedo evasion.
- Generally, the bonus is proportional to the square root of the improvement level,, with multiplier coefficient varying depending on a stat and equipment. This also means that upgrading a higher level equipment would give relatively lower gain per star than upgrading a lower level equipment.
- More precisely, for a given equipment setup and a set of stats, bonuses to stats are assumed to follow the following formula:.
- For example, if (day battle firepower) and a heavy gun and an AP shell are equipped, then the formula should be interpreted as or, using the table below,, with basic attack power for day battle shelling being (fleet bonus is 5 for normal fleet). Note that there is no intermediate flooring under summation, that is, for example, if both equipment are at ★+8, then the bonus is, not nor. Fractional values can matter when pre-cap modifiers are taken into account, because there is no floor before the pre-cap modifiers are applied. The effect this has is dependent on the value of.
- The following table shows multipliers for different stats and equipment:[1]

- Accuracy multiplier for various equipment like guns, AP shells, and AA Radar is currently believed to be 1.[12]
- Effects on low morale seem to be lower (that is, the morale modifier is applied).
- Overall accuracy bonus might have an upper limit of 10%, or a limit that depends on type or number of equipment.[citation needed]
- Radar improvements should give accuracy bonus.[13]
- For Seaplane Reconn, no effects are detected so far.[14]
- Accuracy multiplier for torpedo is 2
- In the following table, ○ mean improving the equipment is verified to give extra accuracy in that stage, × mean no change in accuracy have been observed, ? mean it is still not sure and empty cells mean no test have been done on that yet.[15]

Carrier-Based Fighters |
- Sonar improvements increase evasion against enemy torpedo attacks.[17][18]
- Since they also give firepower they could potentially be useful for torpedo squadron maps where dodging closing torpedo salvos often determines whether a run is successful.
- Seaplane Reconn improvements increase Contact Selection Rate, but not Initial Rate.[19]
- Landing Craft and Special Amphibious Tanks improvements give a linear increase to expedition incomes and Anti-Pillbox Damage Bonus in addition to their original bonus. (Refer to linked pages for details)
- As shown in the table, so far there are no known effects on support shelling (firepower bonus is known to be zero).
- Carrier-based Fighter improvement is currently believed to give additional linear ~0.2★ AA in Fighter Power equation per improvement, and Carrier-based Bomber (Fighter-Bomber) is currently believed to give additional linear ~0.25★ AA.
