The BL 9.2 inch naval gun Mk VIII was designed for the new cordite propellants and was the first British wire-wound gun of this calibre.
It was mounted on the Powerful-class cruisers from 1897. After they were decommissioned some of the guns were used in coast defence in the UK, and from 1916 one was mounted on the monitor HMS Marshal Ney.
