The crowning achievement of naval artillery was the Dreadnought-era battleship. The dominance of the modern naval battleship was from about 1906 to the start of World War II during which typical main armament rose from 305-millimetre (12 in) guns to 381-millimetre (15 in) guns or 406-millimetre (16 in) guns with consequent increase in range and shell firepower. The largest naval guns ever mounted were the 460-millimetre (18 in) guns used on the Japanese Yamato class battleships, firing a 1,460 kilogram (3,219 lb) projectile to a maximum range of 42,000 metres (45,930 yards).
