Query: Who invented the submarine?
Although there were various plans for submersibles or submarines during the Middle Ages, the Englishman William Bourne designed one of the first prototype submarines in 1578. This was to be a completely enclosed boat that could be submerged and rowed beneath 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 in order to increase or decrease the volume of water to adjust the buoyancy of the craft. The sketch (left) suggests that the depth adjustment was by means of a crankset projecting above the surface. There is no obvious accommodation for crew. The first submersible to be actually built in modern times was constructed in 1605 by Magnus Pegelius. Its fate was to become buried in mud. 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."
It's unclear whether or not Napier ever carried out his plans. Henry Briggs, who was professor of mathematics at Gresham College, London, and later at Oxford, was a friend of Napier, whom he visited in 1615 and 1616, 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. Hence, it is not impossible that it was because of the interest taken by Napier in the submarine that Briggs came in touch with Drebbel.
The submarines ("I-52"-class) were submarines of the Imperial Japanese Navy, designed and built by Mitsubishi Corporation, between 1943 and 1944, as cargo carriers. They were quite long and carried a crew of up to 94 officers and enlisted. They also had a long cruising range at a speed of .
Following World War I, the Imperial Japanese Navy General Staff began to re-consider submarine warfare as an element of fleet strategy. Before the war, the Japanese Navy regarded submarines as useful only for short-range coastal point defense. However, based on the success of the Imperial German Navy in deployment of long-range cruiser-submarines for commerce raiding Japanese strategists came to realize possibilities for using the weapon for long range reconnaissance, and in a war of attrition against an enemy fleet approaching Japan. Procurement for a large, long-range Japanese submarine was authorized in fiscal 1918 under the Eight-six fleet program, under the designation S22.
"Project S22" was based on the latest Royal Navy design, the British K class submarine. Japanese ties to Great Britain via the Anglo-Japanese Alliance were still strong. "Project S22" was laid down at Kure Naval Arsenal on 6 April 1921, launched on 29 November 1921 and completed on 20 June 1924.
Imperial Japanese Navy (IJN) submarines formed by far the most varied fleet of submarines of World War II, including manned torpedoes ("Kaiten"), midget submarines ("Kō-hyōteki", ), medium-range submarines, purpose-built supply submarines (many used by the Imperial Japanese Army, see Type 3), fleet submarines (many of which carried an aircraft), submarines with the highest submerged speeds of the conflict ("Sentaka" ), and submarines able to carry multiple bombers (World War II's largest submarine, the Sentoku ). They were also equipped with the most advanced torpedo of the conflict, the oxygen-fuelled Type 95 (which are sometimes confused with the famed Type 93 Long Lance torpedo).
In 2005, Hawkes and adventurer Steve Fossett teamed up to create a submarine that could be piloted by an individual to the deepest part of the ocean. This spot in the Pacific Ocean, called Challenger Deep, is approximately under the ocean's surface and is thought to be the deepest point in the ocean. Together they began to develop the "Challenger" submersible with this goal in mind. However, in 2007 Fossett lost his life in a fatal accident in the Sierra Nevada Mountains of California before the feat could be attempted.
In 1904 Kawasaki Dockyard Company purchased plans for a modified version directly from Holland, and built two boats (Hulls No. 6 and 7), with the help of two American engineers, Chase and Herbert, who had been assistants to Holland. The Kawasaki-type submarines displaced 63 and 95 tons when submerged, and measured in overall length, respectively. both vessels measured at the beam. This contrasted with the original five imported Hollands-type submarines which had arrived that same year, at over 100 tons submerged, in overall length and beam. The Kawasaki Type #6 and #7 submarines had gained extra speed and reduced fuel consumption by . However both boats could launch only one torpedo, and each was manned by 14 sailors, whereas the imported Holland-type submarines could fire two torpedoes and could be operated by 13 sailors. This new type was designated the Type 6 submarine by the Imperial Japanese Navy, and was used primarily for test purposes.
Two submarines of the United States Navy have been named Cuttlefish for the cuttlefish, a ten-armed marine mollusk similar to the squid.
The submarines that Electric Boat sold to Japan were based on the Holland designs, known as Holland Type VIIs similar to the American s. The five imported Hollands were originally built at Fore River Ship and Engine Company in Quincy, Massachusetts under Busch's direction for the Electric Boat Company back in August–October 1904. They were shipped by freighter from Seattle, Washington in Knock-down kit form to Japan, and then reassembled by Arthur Leopold Busch at the Yokosuka Naval Arsenal, which was then Japan's largest naval shipyard, to become Hulls No. 1 through 5 and were designated Type 1 submarines by the Japanese Navy.
The ("I-15"-class) submarines (, , , , , , , , , , , , , , , , , , , ) were the most numerous type of submarines of the Imperial Japanese Navy during World War II. In total 20 were made, starting with "I-15", the class ship. These were fast, very long ranged, and carried a single Yokosuka E14Y seaplane, located in a hangar in front of the conning tower, launched by a catapult.
MacInnis led another series of dives in 1995 to salvage the bell from "Edmund Fitzgerald". The Sault Tribe of Chippewa Indians backed the expedition by co-signing a loan in the amount of $250,000. Canadian engineer Phil Nuytten's atmospheric diving suit, known as the "Newtsuit," was used to retrieve the bell from the ship, replace it with a replica, and put a beer can in "Edmund Fitzgerald"s pilothouse. That same year, Terrence Tysall and Mike Zee set multiple records when they used trimix gas to scuba dive to "Edmund Fitzgerald". The pair are the only people known to have touched the "Edmund Fitzgerald" wreck. They also set records for the deepest scuba dive on the Great Lakes and the deepest shipwreck dive, and were the first divers to reach "Edmund Fitzgerald" without the aid of a submersible. It took six minutes to reach the wreck, six minutes to survey it, and three hours to resurface to avoid decompression sickness, also known as "the bends."
Stainless steel was invented in 1913 by Harry Brearley of Sheffield, working for Firth Brown Steels (now called Sheffield Forgemasters). SAE 304 stainless steel is the most common stainless steel today, invented by Dr William Herbert Hatfield FRS in 1924 at Firth-Vickers known as Staybrite 18/8, a chromium-nickel steel. Many Swiss watches were mostly made out of Staybrite.
The Imperial Japanese Navy's doctrine of fleet warfare ("guerre d'escadre") resulted in its submarines seldom posing a threat to allied merchant convoys and shipping lanes to the degree that the Kriegsmarine's U-boats did as they pursued commerce raiding against Allied and neutral merchant ships. During the war, IJN submarines did sink about 1 million tons (GRT) of merchant shipping (184 ships) in the Pacific; by contrast U.S. Navy submarines sank 5.2 million tons (1,314 ships) in the same period, while U-boats of Nazi Germany's "Kriegsmarine", the IJN's Axis partner, sank 14.3 million tons (2,840 ships) in the Atlantic and other oceans. During the last two years of the War in the Pacific, many IJN submarines were also occupied serving to transport supplies to isolated island garrisons, ones that had been deliberately bypassed by the Americans and the Australians and which could not be reached by surface transports because of blockade by Allied warplanes and naval vessels.
On October 10, 1913, President Woodrow Wilson sent a signal from the White House by telegraph which triggered the explosion that destroyed the Gamboa Dike. This flooded the Culebra Cut, thereby joining the Atlantic and Pacific oceans via the Panama Canal. (a floating crane built by Lobnitz & Company and launched in 1887) was the first self-propelled vessel to transit the canal from ocean to ocean. This vessel crossed the canal from the Atlantic in stages during construction, finally reaching the Pacific on January 7, 1914. (a cargo and passenger ship built by Maryland Steel, and launched in 1902 as SS "Tremont") on August 3, 1914 was the first ship to transit the canal from ocean to ocean.
Despite these advantages, IJN submarines achieved remarkably little during World War II primarily having in hindsight suffered from the antiquated strategy of the Imperial Japanese Navy General Staff, who viewed submarines as little more than scouts whose main role was to locate and shadow enemy naval task forces in preparation for a decisive surface conflict. Maybe the IJN General Staff was slow to change as the submarines were generally slow to dive, easy to track with radar and sonar, difficult to maneuver underwater, and less sturdy than their German U-boat counterparts.
In early 1913, Benoist and Jannus initiated the development of a large new flying boat capable of transatlantic flight. When in early 1914 the "Daily Mail" of London offered a $50,000 prize for the first transatlantic flight of under 72 hours, the two men developed the Type XV flying boat, capable of remaining aloft for 40 hours with six passengers on board. It was ready to fly in 1915, but by then the outbreak of World War I in late July 1914 had made a transatlantic attempt impossible. Benoist Aircraft and the St. Louis Car Company jointly proposed the construction of 5,000 Type XVs for the United Kingdom for use on antisubmarine patrols, but the British preferred Curtiss flying boats and nothing came of the idea.
At the outbreak of World War I, Fessenden volunteered his services to the Canadian government and was sent to London where he developed a device to detect enemy artillery and another to locate enemy submarines. Other efforts included a version of microfilm, that helped him to keep a compact record of his inventions, projects and patents. He also patented the basic ideas leading to reflection seismology, a technique important for its use in exploring for petroleum, and received patents for diverse subjects that included tracer bullets, paging, television apparatus, and a turbo electric drive for ships.
While Japan had a large number of submarines, they did not make a significant impact on the war. In 1942, the Japanese fleet submarines performed well, knocking out or damaging many Allied warships. However, Imperial Japanese Navy (and pre-war US) doctrine stipulated that only fleet battles, not "guerre de course" (commerce raiding) could win naval campaigns. So, while the US had an unusually long supply line between its west coast and frontline areas, leaving it vulnerable to submarine attack, Japan used its submarines primarily for long-range reconnaissance and only occasionally attacked US supply lines. The Japanese submarine offensive against Australia in 1942 and 1943 also achieved little.
Pascal Bernabé is a French scuba diver who in 2005 laid claim to the world best for depth on a deep dive using self-contained breathing apparatus. Bernabé claimed to have reached a maximum depth of using trimix on 5 June 2005 near Propriano, Corsica. This was actually deeper than the official deepest scuba dive recognized by Guinness World Records at the time. That mark, set by Nuno Gomes in Dahab, Egypt, was of sea water. However, Bernabé's claimed deepest dive was not included in the "Guinness Book of World Records" due to insufficient evidence of such a dive ever being performed.
In September 1762, the British invaded the Philippines and took over the Spanish main naval base in Manila Bay. This prompted the Spanish military to scout for the next promising naval station. The expedition returned with the good news for the naval command - a natural bounty and deep waters at Subic Bay. King Alfonso XII issued a decree in 1884 that declared Subic as "a naval port and the property appertaining thereto set aside for naval purposes." Construction of an arsenal and ship repair yard ensued March 8 the following year, as ordered by the new settlers' Naval Commission. Subic Bay's potential as naval station was realized by the Americans. Commodore George Dewey and his men engaged in a battle that destroyed the Spanish Army in 1898, and the Americans took over Subic Bay on December 10, 1899.
The Imperial German Navy (, "Imperial Navy") was the navy created at the time of the formation of the German Empire. It existed between 1871 and 1919, growing out of the small Prussian Navy (from 1867 the "North German Federal Navy"), which primarily had the mission of coastal defence. Kaiser Wilhelm II greatly expanded the navy, and enlarged its mission. The key leader was Admiral Alfred von Tirpitz, who greatly expanded the size and quality of the navy, while adopting the sea power theories of American strategist Alfred Thayer Mahan. The result was a naval arms race with Britain as the German navy grew to become one of the greatest maritime forces in the world, second only to the Royal Navy. The German surface navy proved ineffective during World War I; its only major engagement, the Battle of Jutland, was indecisive. However, the submarine fleet was greatly expanded and posed a major threat to the British supply system. The Imperial Navy's main ships were turned over to the Allies, but were sunk at Scapa Flow in 1919 by German crews.
The IJN submarine arm did have a number of notable successes against American warships, however. During the Battle of Midway, administered the final "coup de grace" that sank the fleet carrier , as well as sinking the destroyer . A few months later, on September 15, 1942, with a single salvo of torpedoes, Japanese submarine sank the fleet carrier and damaged both the battleship and the destroyer . On November 13, 1942, the submarine torpedoed and sank the anti-aircraft cruiser , and a year later on November 23, 1943 the submarine torpedoed and sank the escort carrier , both with heavy loss of life. The had the distinction of both severely damaging the heavy cruiser , knocking her out of the war for a year, on October 20, 1942, and of also sinking (the only American submarine to be sunk by a Japanese submarine in the entire war) on November 16, 1943.
An early book, "The Flying Submarine" (published in 1912) may indicate Westerman's genre. This boys' adventure novel was about a mysterious man from a South American country. He was an inventor, who had discovered a new kind of lighter-than-air gas that he called “helia”, which was much lighter than helium or hydrogen. He used helia in many inventions, including back-packs that could help a man float in the air or fly upwards, and in the remarkable titular submarine that could, when enough helia was used, fly! Eventually he used his flying submarine to win a war between his South American country and its belligerent neighbour.
Among his inventions is a submarine boat with a cylindrical hull of copper having conical ends and with a screw propeller and rudder operated by electric power generated on shore or on ship board, by means of which the torpedo is propelled, guided and exploded. Among Sims’ earlier inventions were various devices in electromagnets and the construction of an electric motor, weighing 45 pounds for light work, with a battery of twenty half gallon Bensen cells that propelled an open boat sixteen feet long with six persons on it, at the rate of four miles an hour. His invention of the submarine torpedo boat was followed by the devising of a boat with a speed of 22 miles an hour to carry a 500 pound charge of dynamite.
Dolphin invented the 'Welman', a one-man submarine that was prototyped at Station IX. The miniature submarine had no periscope so was hard to navigate as the submariner had to look through specially armoured glass segments in the small 'conning tower'. The Welman was designed to attach 560-pound explosive charge to its target by magnetic clips, but this could not be made to work reliably. It was decided to try the Welman submarine in an attack on the Floating Dock in Bergen harbour so on 20 November 1943 MTB635 and MTB625 left Lunna Voe, Shetland, carrying Welmans W45 (Lt. C. Johnsen, Royal Norwegian Navy), W46 (Lt B. Pedersen, Norwegian Army), W47 (Lt. B. Marris, RNVR) and W48 (Lt. J. Holmes, RN). The craft were launched at the entrance to the fjord. Pedersen's W46 became entangled in an anti-submarine net and had to surface, where she was captured by a German patrol craft. Pedersen survived the war in a prison camp and the other three eventually had to be scuttled. Their operators made their way north with the help of Norwegian resistance members and were picked up in February 1944 by MTB653. The failure made the Royal Navy concentrate on X craft and XE craft, although further Welman trials took place in Australia.
It would be wrong to claim the German submarine fleet of the World wars was directly descended from Wilhelm Bauer’s prototypes, but he nevertheless influenced them. The modern submarine began its history with the inventions of Simon Lake and John Philip Holland. However, the submarine pioneers of the 19th century - de Villeroi, Monturiol, Hunley and others - were all aware of Bauer’s efforts and drew inspiration and even ideas from his submarine.
