The BL 9.2-inch Mk VIII naval gun[3] was designed for the new cordite propellants and was the first British wire-wound gun of this calibre.

[edit]

The guns were mounted on the Powerful-class cruisers from 1897 until their decommissioning. After they were decommissioned some of the guns were used in coast defence in the UK, and from 1916 on one was mounted on the monitor HMS Marshal Ney.
