Up to and during the First World War, the Germans attempted to challenge the might of the Royal Navy, only to be blockaded and stymied by the latter's superior tactics (drawn from centuries of experience) and numbers however, the effectiveness of Germany's U-boats on unescorted shipping taught the British important lessons in convoy tactics - a lesson which the Americans would soon learn upon their entry into the Second World War. The Royal Navy pioneered many advances in naval technology and strategy: the construction of HMS Dreadnought, whose revolutionary design so shocked the world that battleships for a time became generically labelled as 'dreadnought' or 'pre-dreadnought' the first battlecruisers the world's first carrier-launched, all-aircraft attack at the Battle of Taranto anti-submarine warfare advancements such as sonar, high-frequency direction finding, hydrophones, depth charges, and the 'Hedgehog' anti-submarine mortar and innovations to aircraft carrier designs such as concentrating the bridge and flight control tower into one island superstructure (as opposed to a flush deck configuration), steam catapults and ski-jump ramps for launching aircraft, and full-length, armored, and angled flight decks. Due to this historical prominence, although many other navies have similar designations, only the United Kingdom's is referred to as 'The Royal Navy' without further qualification. From the early 18th century until the middle of the 20th century, the Royal Navy of the United Kingdom was the most powerful in the world, defeating the French, Dutch and Spanish navies to establish the British Empire as the dominant world power - the 'empire on which the sun never sets' - influencing many aspects of life in numerous countries across the world, even today.
