This meant that the presence of smaller weapons could make it more difficult to get hits with larger guns. Some were concerned that the high rate of fire of smaller guns was mitigated by the fact that it was difficult to acquire the range by gun splashes when there were so many splashes around the target. The increased accuracy meant that ships could engage and expect hits at previously unimagined distances, giving an advantage to bigger, longer-ranged weapons. However, developments in optics and improvements in gun accuracy at the beginning of the twentieth century began to tilt the balance towards heavier guns. Indeed, some argued that large armored ships with small weapons (armored cruisers, which were roughly the same size as battleships) could defeat battleships by saturating them with fire. Naval architects believed that most engagements would take place within the range of the smaller guns, and that a variety of guns would combine penetrating power with volume. Most of the original dreadnoughts were scrapped after the end of World War I under the terms of the Washington Naval Treaty, but many of the newer super-dreadnoughts continued serving throughout World War II.State-of-the-art battleship armament in the late nineteenth century involved a mix of large- and small-caliber weapons. These more powerful vessels were known as " super-dreadnoughts". Within five years, new battleships outclassed Dreadnought herself. Successive designs increased rapidly in size and made use of improvements in armament, armour, and propulsion throughout the dreadnought era. Dreadnought races sprang up around the world, including in South America, lasting up to the beginning of World War I. As dreadnoughts became a crucial symbol of national power, the arrival of these new warships renewed the naval arms race between the United Kingdom and Germany. Her design had two revolutionary features: an "all-big-gun" armament scheme, with an unprecedented number of heavy-calibre guns, and steam turbine propulsion. The first of the kind, the Royal Navy's HMS Dreadnought, had such an effect when launched in 1906 that similar battleships built after her were referred to as "dreadnoughts", and earlier battleships became known as pre-dreadnoughts. The dreadnought (alternatively spelled dreadnaught) was the predominant type of battleship in the early 20th century.
