Most people rightly consider the submarine to be a relatively recent invention but the idea of an underwater vessel actually goes way back to ancient times and very early naval warfare. a medieval legend tells of how alexander the great used a submersible mission to spy on his enemies. it cannot be confirmed whether it was an actual submarine and it is believed that it was most likely a large sort of diving bell a . however, it at least proves that the idea to create a machine in which man could remain underwater and undetected for long periods was already in the mind of man. during the middle ages european inventors made many attempts at developing submarines. leonardo da vinci and other great thinkers b the first submarine that really worked was built around 1620 by a dutchman by the name of cornelius drebbel who was working for king james i of england. accounts from the time, tell of how he made a submerged journey down the river thames in an adapted rowing boat. no one knows how his vessel actually worked and rumours that king james c engineers all over europe continued experi - menting d . at the same time, their military potential became obvious and by 1727 14 types of submarines had been invented in england alone. in 1776, the american david bushnell developed the first military submarine e . turtle attempted to sink a british ship hms eagle in new york harbour but failed. however, during the american civil war submarines were to be used more successfully. the french- designed alligator was the first us navy sub to use compressed air and an air filtration system. it was also the first submarine to plant electrically detonated mines on enemy ships. alligator was eventually lost in a storm off north carolina f in 1897, irish engineer john philip holland developed the first submarine with the power to run submerged for any considerable distance, and the first to combine electric motors for submerged travel and gasoline engines for use on the surface. his submarines would be officially adopted by both the us and british navies and found the bases of future modern submarine fleets. made designs of underwater vehicles 2 with different ways to make a submarine 3 but the hope of building functional submarines was far from lost 4 that was used and not an actual submersible machine 5 in all weather and sea conditions 6 capable of moving under water and carrying out operations 7 took part in the experiment are most likely untrue , добрые люди, заранее
