Anti-Ship Artillery Effectiveness

This simple program calculates a rough stimation of the effectiveness of the anti-ship artillery of a given battleship or any other classical warship that uses this kind of artillery. The calculation is made by taking into account the most fundamental aspects of an artillery mounting created with the purpose of destroying or damaging warships of any size. Other factors that could be relevant cannont be taken into account by the program, such as the disposition of the mountings and the resulting firing arcs. The program accepts up to eight batteries to be calculated, thus allowing complex layouts to be calculated. Values for Battery #1 are required, the rest are optional.

Below there is a list showing the values for some well-known historical capital ships. The higher the number, the higher the effectiveness of the artillery installed in that warship to inflict damage in other ships. The darker section of the bar refers to main (primary) armament. In older warships I included all the artillery in the computing, while in later warships I excluded any artillery whose primary role is anti-aircraft.
