On its only test mission, the Turtle was assigned the task of bombing the British HMS Eagle off the waters of New York City, but its pilot was unable to screw the explosive into the Eagle ’s copper hull. Unfortunately, the Turtle failed to sink any ship. As if it was not dangerous enough simply to get in the water sealed inside thisĭevice, the Turtle also had a large explosive device attached to it in the hopes the operator could maneuver under an enemy ship, screw the explosive into the ship ’s hull, and depart before the explosive ’s timing device discharged it. It resembled an egg squashed thin with a height of 6 ft (2 m), and had two hand-cranked screw propellers, a hand-operated control lever connected to the rudder, foot-operated pumps to let water in or send it out (to submerge or surface), and a crudely lit control panel. It was unable, however, to make deep descents.ĭuring the American Revolution, American inventor David Bushnell (1742 –1824) built a one-person submarine called the Turtle. ![]() During a demonstration for James I (1603 –1625) in 1620, this vessel was successfully piloted just under the surface of the Thames River. It was propelled either on or beneath the surface by eight oars sealed through the sides with leather flaps. It consisted of greased leather over a wooden framework. Dutch inventor Cornelius Drebbel (1572 –1633) built the first known submarine. While no record exists concerning its manufacture, the ship, according to Bourne, could be submerged or raised by taking in or expelling water from between the double hulls. Published by English mathematician William Bourne (1535 –1582) in his Inventions or Devices, the document describes a ship with two hulls, the outer made of wood. The first known treatise on submarines (also called subs) was written in 1578. A submarine (the word originally meant under the sea) is a boat that is built to be operated under water for extended periods of time.
