Forgotten History: World's Biggest Black Powder Cannon - a 100-Ton Gun
The Armstrong 100-ton gun, the largest muzzle-loading cannon ever built, was a response to Italian naval ambitions in the late 19th century. Despite its immense size and power, capable of firing a 2,000-pound shell with a 450-pound black powder charge, its service life was cut short by the invention of smokeless powder. The gun's operation relied on a sophisticated steam-powered hydraulic system for loading, rotation, and elevation, showcasing advanced engineering for its era.
