Cannone navali da 381/40とは 意味・読み方・使い方

The Cannone navale da 381/40 was an Italian naval gun ordered in 1913 to equip the battleships of the Francesco Caracciolo class. The ships were cancelled in 1916 and the guns intended for them were diverted to other uses. Seven were turned over the Army and turned into railroad guns, a number were used as coast defense guns and the rest were used on monitors to provide naval gunfire support for the Army. Most of the monitors were disarmed after World War I and their guns were transferred to coastal batteries, but the railroad guns and the coast defense guns were used throughout World War II.
