QF 4.7-inch Mk I–IV naval gun

Common card · No. 455608

The QF 4.7-inch gun Mks I, II, III, and IV were a family of British quick-firing 4.724-inch (120 mm) naval and coast defence guns of the late 1880s and 1890s that served with the navies of various countries. They were also mounted on various wheeled carriages to provide the British Army with a long-range gun. They all had a barrel of 40 calibres length. The gun was originally designed to replace the older BL 5-inch (127 mm) naval guns. It was optimised for the modern smokeless propellants, such as cordite, and could be loaded and fired far more rapidly than the BL 5-inch gun while firing a shell only slightly lighter.
