The EOC 8 inch 45 caliber were a family of related 8-inch (203 mm) 45 caliber naval guns designed by the Elswick Ordnance Company and manufactured by Armstrong for export customers before World War I. In addition to being produced in the United Kingdom licensed variants were produced in Italy and in Japan.[1] Users of this family of gun included the navies of Argentina, Chile, China, Italy, Japan and Spain. This family of guns saw action in the Spanish–American War, Boxer Rebellion, Russo-Japanese War, Italo-Turkish War, World War I and World War II. In addition to its naval role it was later used as coastal artillery and siege artillery after the ships it served on were decommissioned.[2]
