RML 9-inch 12-ton gun
Rifled muzzle loading naval gun / From Wikipedia, the free encyclopedia
The RML 9-inch guns Mark I – Mark VI[note 1] were large rifled muzzle-loading guns of the 1860s used as primary armament on smaller British ironclad battleships and secondary armament on larger battleships, and also ashore for coast defence. It should not be confused with the RML 9-inch Armstrong Gun, used by the Dutch navy, the Spanish Navy, and other navies.
