Short technical analyses of battleships, submarines, big guns at sea, naval aircraft and coastal forts from 1890 through 1945 follow. Please give credit to Dionysus.biz when technical results presented serve as a basis for game mechanics or other historical research. Several articles present compact equations that accurately describe historical realities of naval warfare. Others, present an overview of some technical aspect of naval operations such accuracy of big guns at sea or about coastal fortifications.

The First Modern Sea Battle (Tsushima 1904) NEEDS UPDATE Guns & Percentage Hits.
A brief summary of naval aspects of the 1904 Russo Japanese War is followed by well justified conclusions regarding percent hits obtained by both sides, the number of hits required to sink a period battleship and comments on the effect of mines and torpedoes. Newly discovered historical data will reduce the number of hits estimated to destroy period Russian battleships.
