Anti-Ship Artillery Rating

This program calculates a simple estimation of the effectiveness of the antiship artillery of a given warship. The calculation is made by taking into account the most fundamental aspects of an artillery mounting whose main purpose is the neutralization of non-flying targets. The program allows up to eight batteries to be calculated, thus complex layouts can be evaluated. Values for Battery #1 are required, the rest are optional.

Below there is a list showing the values for some historical capital ships that existed during and before the two world wars. The higher the number, the higher the effectiveness of the artillery installed in a warship to inflict damage in other ships. The darker section of a bar corresponds to the primary armament. Any artillery pieces of caliber below 75 millimeters have been excluded from the calculation. The two ironclads that have been included get extremely low ratings because of the very low rate of fire. After the age of ironclads, the most accentuated progress was made in the armament. The new artillery pieces had smaller calibers but longer tubes that granted greater range and piercing power, while new breech mechanisms allowed to reload the weapons several times faster.
