The BL 9.2 inch gun Mark XI was a British 50 calibre high-velocity naval gun which was mounted as primary armament on armoured cruisers and secondary armament on pre-dreadnought battleships.
History
The gun with its increased length of 50 calibres was an attempt to extract a higher velocity, and hence more range and armour-piercing capability, from the 9.2 inch gun. Like other British 50-calibre guns of the period it was relatively unsuccessful, and was the last model of 9.2 inch gun Britain built.
Guns were mounted in the following ships :
- Minotaur class armoured cruisers laid down 1905 & completed 1908 - 1909 : 2 twin mounts.
- Lord Nelson class battleships laid down 1905 & completed 1908 : 4 twin mounts and 2 single mounts.
