The Cannone da 152/45 was a heavy gun which served with Italy during World War I and World War II. It was an expedient mating of a naval gun barrel placed on a land carriage to fulfill the Italian Army's need for long-range counter-battery work. The carriage was placed on a firing platform which had to be dug into the ground. A pit had to be dug into the ground to allow the gun to fire at high elevations. Some 53 were in Italian service in 1939.
