History[edit | edit source]

UK service[edit | edit source]

Forward turret on HMS Swiftsure

Elswick supplied 5 of their 10-inch 45-calibre guns for use on the battleship Constitución that they were building for Chile. Britain took the ship over in 1903 as HMS Swiftsure, and the guns were designated BL 10 inch Mk VI in UK service. These guns fired a 500-pound (226.8 kg) projectile using 146 pounds 12 ounces (66.56 kg) cordite MD propellant.[6]

Italian service[edit | edit source]

Forward turret on Italian armoured cruiser Pisa 1932

Elswick supplied later more powerful 1907 models of its 10-inch 45-calibre guns for the Pisa-class and San Marco-class armoured cruisers of 1907 & 1908.[7]
