Who invented the submarine

The submarine was invented by Cornelius Drebbel, developed and tested between 1620 and 1624.

He made a wooden-framed, leather-covered dinghy in England, with oiled peaks and a sheepskin sac inside. By filling the sac with water, the boat would dive and could dive to a depth of 3 to 5 meters underwater.

In 1775, the American Revolutionary War broke out. The American David Bushnell built a wooden-hulled submarine, the Turtle, powered by a hand-cranked propeller and piloted by a single man, which could stay underwater for about half an hour.

The submarine's first attack mission was in 1776. "The Turtle was shaped like a goose egg, with its pointed end facing downward, and could accommodate only one person inside, with a water closet and pump in the bottom, a hand-cranked propeller, and barrels of explosives hanging from the outside of the boat.

Submarine History Timeline

In 1776, American D. Bushnell built a single-manned wooden-hulled boat, the Turtle.

In 1801, the American R. Fulton built the "Nautilus" submarine, the hull for the iron frame copper shell, 7 meters long, carrying two mines, operated by four people. Folding mast is used in the water, powered by sails. Underwater propulsion is by hand-cranked propeller.

In 1863, France built a "diver" submarine. Hull imitation dolphin shape design, 42.67 meters long, displacement of 420 tons. Using a power of 59 kilowatts (80 horsepower) steam engine for power, the speed of 2.4 knots, can dive underwater for 3 hours, diving depth of 12 meters.

In 1881, T. Nordfeldt and G. Garrett built the submarine Nordfeldt, which was equipped with torpedo tubes for the first time.

In 1881, the U.S.-built submarine Holland II was fitted with torpedo tubes capable of firing torpedoes underwater, an important development in the history of submarine development.

In 1886, Britain built the Nautilus submarine, using battery-powered propulsion, speed 6 knots, range of about 80 nautical miles.

In 1897, the United States built the "Holland" VI submarine, surface use of 33 kilowatts (45 horsepower) gasoline engine power plant, speed 7 knots, range of 1,000 nautical miles; underwater use of electric motors, speed 5 knots, range of 50 nautical miles, which is the submarine the beginning of dual-propulsion system.

In 1898, the Frenchman Maxime Lauboeuf pioneered the double-hulled structure of the "narwhal", storing ballast water between the two hulls, the advantage of the buoyancy is greatly increased.
