The QF 6 inch Gun Mark N5 (initially designated QF 6 inch Mk V) was a British naval gun, development of which started during the Second World War, but did not actually enter service with the Royal Navy until the first Tiger-class cruiser was commissioned in 1959. Fitted in pairs to the new and complex Mark 26 dual purpose gun turret designed for rapid automatic fire, the weapon system gained a somewhat undeserved reputation for unreliability and difficult maintenance, but remained in service until 1979 when they were the last 6 inch guns ever to be fired from a British warship.[1]
