👉 The Naples Weapon, also known as the "Naples Submarine Gun," was a naval artillery piece developed by Italy during World War II. It was designed to fire 12.7 cm (5-inch) high-explosive shells from a submerged position, making it highly effective for anti-submarine warfare and coastal defense. The weapon consisted of a submerged gun platform, an armored hull, and a sophisticated system for firing the shells underwater or on the surface. Its unique design allowed it to remain hidden from enemy detection until the final moments of firing, providing a significant tactical advantage. However, its operational effectiveness was limited due to the challenges of maintaining stability and accuracy in the water.
