The submarine (submarine) is the warship which can dive under water having the hull of the withstand pressure structure. By the ship of similar structure, the ship for private bottom of the sea inquiry use and underwater sight-seeing is called a midget submarine, diving ship. The submarine is different from other water war vessels in a cruiser or a destroyer and has a big characteristic that a submarine voyage is possible. Because I compare it at the time of the water navigation at the time of the submarine voyage, and cover detection probability decreases sharply, I can keep high secret agent characteristics. Ability for this secret agent action is a characteristic of the submarine maximum, and it is said "the ultimate stealth bomber weapon which the human invented". The plan to navigate the water with the hull of the waterproofing structure is seen from ancient times. It has been dreamed of which the episode that I hit the window of the barrel of the glass to an iron basket in ("a legend" letter) of the legend Alexandros(Tralles) romance after the death of Alexander the Great, and went into the sea was added to at the time in the fourth century in A.D. Dutch Cornelius made a submarine (the thing which I row an oar with human power, and promote it) for the British navy in 1620, but I was not used as the actual fighting. As for the submarine which it is constructed, and was cast the actual fighting into, the turtle midget submarine which I appeared in 1776 is really a beginning. The number of the crewmen equipped it with one, a spiral type propulsive engine of the human power drive with the egg-shaped hull, and U.S.A. used this warship at the time of American War of Independence, but was careless for hostile craft boat sinking. During the American Civil War, as for human power promotion midget submarine Hanley of C.A. constructed in State of Alabama Mobil of the southern part, attack attacked and sank Federal army carving wood steam sailing boat blockading the port out of State of South Carolina Charleston Port in 1864 by a decoration mine. This is the first example that a submarine (a midget submarine) sank an enemy ship during war. Hanley did not return with a crewman, but I am discovered in the bottom of the sea out of a port for further 1995 years, and it is withdrawn in 2000 and saves it, and it is exhibited. The name of a warship was associated with one of the building investors Holles Lawson Hanley, and it was named, but the person in question died in the second submergence accident that occurred during boarding as a coxswain. Catalonian Narcissus catches the Spanish naval support in 1867 and succeeds in letting I depend for the non-atmosphere and promote submarine "II". In addition, a midget submarine and the David type half midget submarine were considered to be an unfair, devilish weapon in those days by both ally and enemy and let the captain of Federal army ironside nu iron size blockading Charleston attacked the warship in a dark night and damage and threatened you when they could write a coxswain of David that it was it to a captive for the trial by "the crime that they used the weapon which was not recognized in a civilized country" for in New York and did it for hanging. The first submarine equipped with an internal combustion engine is Holland submarine constructed in U.S.A. in 1900 (underwater displacement 74t). It was the method how the power system of this warship was connected directly with with a gasoline engine and a motor of the main opportunity, and it was it with the ancestor of the submarine of modern times. The full-scale activity of the submarine consists of World War I. It was Deutsches Reich to have made good use of a submarine in each countries. I gave the military gains that a submarine of the German navy attacked and sank four British cruisers in September, 1914 just after the outbreak of war. Deutsches Reich constructed a sailing submarine in large quantities and accomplished commerce destruction war for British beginning allied powers and gave the allied powers merchant ship corps severely wounding and showed the power to the world. An U-boat of German to mean a submarine before long(Unterseeboot) I became the pronoun which expressed a German naval submarine. The U.K. which was a hypothetical enemy constructed the M type submarine which I burnt coal, and was equipped with the high speed submarine that fleet accompanying was possible and the main battery of the battleship by a steam turbine in one and was opposed. As for the submarine of the early period of Great War, in the main plane, the diesel engine which could be superior to the mileage in substitution for a gasoline engine became the mainstream at underwater displacement 100t - around 600t. For a flying range and the increase of the ammunition burden, as for U81 type that upsizing was completed 42 as for the submarine in progress, last part of Great War, 4 reached the size of about 2,500t water displacements with finished U139 type in about 1,000t underwater displacements, Great War last years. The then submarine was water speed 15-20 knots, submerged speed 8 knots, greatest submarine voyage depth around 100m. The victorious nation obtained German navy submarine as a win warship including U.S.A. and took in the technology. Based on the technology of a submarine with each country made in Germany, I develop it to the science of war thought of the own country. Great Japanese Empire assumed a fleet decisive battle in the very large Pacific and constructed a large-scale submarine of water displacement more than 2,000t having a carrier-based plane a lot. France was equipped with 20.3cm multiple-barreled cannon tower and of one cup of treaty restrictions, a captive labor camp for commerce destruction wars and constructed world maximum and circulation Hiroshi submarine (water 2,880t) said to in those days. It is just just before destruction in the merchant ship corps of the own country; the prodding crowded U.K. lets prohibit submarine possession in Versailles Treaty for Germany…
