Submarines move under water. Man's desire to travel under water resulted in the development of submarines. Dutch inventor Cornelius Van Drebbel invented the submarine in 1620.
Earlier to him, in 1578 William Bourne indicated the design of a completely enclosed boat which could be submerged and rowed under the surface by reducing its volume by contracting its slides through hands vises. It was to be made of wood covered with water proof leather. But the Bourne did not actually build it.

Drebbel launched his submarine for James. He took it at depths of 3 to 4 meters underwater in the river Thames. The submarine had greased leather over a wooden frame and oars that came out through the sides and were sealed with leather flaps.

The first proper submarine was "Turtle". It was an egg shaped wooden vessel built by Dairel Bushnell, an American engineer. It was mainly used to attack British boats during the American war of independence in 1776. It was one man submarine.

The turtle tried to sink a British man of war in New York labor. Nautilus a submarine was designed by Robert Fulton for Napoleon. By 1727 there were 14 different types of submarine. In 1875 the Irish emigrant to US John built a series of submarines which were used by the Americans and British.

Today submarines are used by the navy all over the world.
