Henry Briggs, who was professor of mathematics at Gresham College, London, and later at Oxford, was a friend of Napier, whom he visited in 16, and was also an acquaintance of Cornelius Van Drebbel, a Dutchman in the service of James I of England, who designed and built the first successful submarine in 1620. It is unclear whether or not Napier ever carried out his plans. In 1596 the Scottish mathematician and theologian John Napier wrote in his Secret Inventions the following: "These inventions besides devises of sayling under water with divers, other devises and strategems for harming of the enemyes by the Grace of God and worke of expert Craftsmen I hope to perform." There is no obvious accommodation for crew. The sketch (left) suggests that the depth adjustment was utilizing a crankset projecting above the surface. Comprising a completely enclosed wooden vessel sheathed in waterproofed leather, it was to be submerged by using hand-operated wooden screw thread adjustable plungers pressing against flexible leather bags located at the sides to increase or decrease the volume of water to adjust the buoyancy of the craft. This was to be a completely enclosed boat that could be submerged and rowed beneath the surface. Submarine by William Bourne, in Inventions or devices, 1578.Īlthough there were various plans for submersibles or submarines during the Middle Ages, the Englishman William Bourne designed one of the prototype submarines in 1578. Two Greeks submerged and surfaced in the river Tagus near the City of Toledo several times in the presence of The Holy Roman Emperor Charles V, without getting wet and with the flame they carried in their hands still alight. Īccording to a report attributed to Tahbir al-Tayseer in Opusculum Taisnieri published in 1562: Later legends suggested that Alexander descended into the sea using a primitive submersible in the form of a diving bell, as depicted in a 16th-century illustration in the works of the Mughal poet Amir Khusrau. At the siege of Tyre (332 BC), Alexander the Great used divers, according to Aristotle. There are images of men using hollow sticks to breathe underwater for hunting at the temples at Thebes, but the first known military use occurred during the siege of Syracuse (415–413 BC), where divers cleared obstructions, according to the History of the Peloponnesian War. The concept of underwater combat has roots deep in antiquity. They remain a focus of popular culture and the subject of numerous books and films.Įarly A 16th-century Islamic painting depicting Alexander the Great being lowered in a glass submersible. They are used extensively in search and rescue operations for other submarines, surface vessels, and air craft, and offer a means to descend vast depths beyond the reach of scuba diving for both exploration and recreation. They are heavily employed in the exploration of the sea bed, and the deepest places of the ocean floor. ![]() The military use of submarines continues to this day, predominantly by North Korea, China, the United States and Russia.īeyond their use in warfare, submarines continue to have recreational and scientific uses. The latter conflicts also saw an increasing role for the military submarine as a tool of subterfuge, hidden warfare, and nuclear deterrent. The Second World War use of the U-Boat by the Kriegsmarine against the Royal Navy and commercial shipping, and the Cold War's use of submarines by the United States and Russia, helped solidify the submarine's place in popular culture. The introduction of the diesel engine, then the nuclear submarine, saw great expansion in submarine use – and specifically military use – during World War I, World War II, and the Cold War. While early attempts, such as those by Alexander the Great, were rudimentary, the advent of new propulsion systems, fuels, and sonar, propelled an increase in submarine technology. Humanity has employed a variety of methods to travel underwater for exploration, recreation, research and significantly, warfare. The history of the submarine spans the entire history of human endeavour as mankind has since early civilisation sought to explore and travel under the sea. ![]()
