Arms and Armour
The 100-ton gun (also known as the Armstrong 100-ton gun) was a British coastal defense gun and is the world's largest black powder cannon. It is a 17.72-inch (450 mm) rifled muzzle-loading (RML) gun made by Elswick Ordnance Company, the armaments division of the British manufacturing company Armstrong Whitworth, owned by William Armstrong. The 15 guns Armstrong made were used to arm two Italian battleships and, to counter these, British fortifications at Malta and Gibraltar.
