When World War I began, Elswick were completing the battleship Sultân Osmân-ı Evvel for the Ottoman Empire, originally begun as Rio de Janeiro for Brazil. It was armed with 14 of a slightly later version of Elswick's 12-inch 45-calibre guns. The battleship was completed as HMS Agincourt and served in the Royal Navy in World War I, with its guns designated BL 12 inch Mk XIII.[1] The gun's performance was similar to the standard Royal Navy equivalent gun, the BL 12 inch Mk X designed by Vickers.
Japan service
Elswick supplied its 12-inch 45-calibre guns to the Imperial Japanese Navy, and they were also manufactured under licence in Japan. In Japanese service from 1908 they became 12"/45 41st Year Type and later after the navy metricised in 1917, 30 cm/45 41st Year Type. They equipped the following ship classes :
- Katori-class battleships commissioned 1906

- Tsukuba-class battlecruisers commissioned 1908
- Mikasa as re-gunned in 1908
