This collection covers 158 artillery and ordnance ammunition objects catalogued under Class XXV, delivered across 705 images in 73 ZIP assets. Class XXV focuses on the larger-scale ammunition associated with artillery and heavy weapons — cannon balls, shells, propellant cases, fuzes, and instructional models spanning from the 17th century through to the 20th. The high image-to-object ratio reflects the complexity and visual interest of these large-format objects.
Artillery ammunition tells a different story to small arms ammunition — the evolution from stone balls through cast iron round shot to explosive shells and modern steel projectiles reflects the industrial revolution in warfare as much as any other category. The Royal Armouries' Class XXV collection documents this evolution with remarkable breadth.
