Fit Bonus and Overweight Penalty

With the introduction of fit gun mechanics on July 28th 2014, ships now will receive fit bonus/penalties depending if the equipped gun fits for the class or if the gun is too heavy for the ship to use.

As fit bonuses are unaffected by morale or combined fleets, it becomes important that you utilize the fit bonuses as much as possible.

Fit mechanics does not apply to the abyssal fleet.

Battleships

Battleships receives accuracy bonuses if the guns are fit and accuracy penalties if its overweight. How much bonus/penalty a ship receives, depends on the battleship class and the caliber of the gun.

Heavy Cruisers

Heavy/Aviation cruisers only require one fit gun to get their fit bonus, there are no overweight mechanics regarding cruisers. Note that the bonuses also apply to torpedo attacks. CA(V)s receives an accuracy bonus of around 10% during night battle when equipped with the following guns:

• 20.3cm Twin Gun Mount
• 20.3cm (No.3) Twin Gun Mount

The following guns are confirmed not to give any fit bonuses:

• 20.3cm (No.2) Twin Gun Mount
• SKC34 20.3cm Twin Gun Mount

Light Cruisers

Light Cruisers, Torpedo Cruisers and Training Cruisers all enjoy an accuracy and firepower bonus when equipped with fit guns. Like Heavy Cruisers, Light Cruisers does not have overweight mechanics.

Firepower

Light Cruisers, Training Cruisers, and Torpedo Cruisers enjoy firepower increase when using any of the following gun:

• 14cm Single Gun Mount
• 14cm Twin Gun Mount
• 15.2cm Single Gun Mount
• 15.2cm Twin Gun Mount
• 15.2cm Twin Gun Mount Kai

It have been suggested that the increase in firepower might follow this relationship:

• Increase in Firepower = √(No. of Fit Single Gun Mount) + 2 × √(No. of Fit Twin Gun Mount)

Accuracy

So far, only limited amount of tests have been conducted to study light cruiser fit gun's effect on accuracy so all information in this section are in-comprehensive and they might be superseded by other, more up-to-date investigations when those information are available.

The accuracy fit bonus only applies if 2 or more fit guns are equipped at the same time. Equipping more than 2 fit guns does not increase the fit bonus. Accuracy increase have been observed for the following guns when they are being equipped on CL

• 14cm Single Gun Mount
• 14cm Twin Gun Mount
• 15.2cm Single Gun Mount
• 15.2cm Twin Gun Mount
• 15.2cm Twin Gun Mount Kai

Accuracy increase have been observed for the following guns when they are being equipped on CLT

• 14cm Twin Gun Mount

Accuracy increase have been observed for the following guns when they are being equipped on CT

• 14cm Twin Gun Mount

Other combinations have not been fully tested yet.

The possibility of accuracy bonus vary across different ship classes have not been ruled out yet.
