The Evolution
Cornelius van Drebbel's submarine
The submarine was first drawn by William Bourne in 1580. Cornelius van Drebbel actually built the underwater boat in 1620. His boat was made of wood and wrapped in leather.
In 1776 David Bushnell, an American, invented the Turtle. The one man boat was pedal powered. It was the first submarine to attack an enemy ship. Four years later in 1880 American inventor Robert Fulton built the Nautilus.

The Alligator
In 1862 the Alligator a submarine from the U.S Navy was put to service. During 1864 the Hunley became the first submarine to sink an enemy boat. Unfortunately the Hunley also sank during the attack.
In about 1900 John P. Holland invents a submarine powered by gasoline for the U.S Navy. As the submarine's need grew gasoline engines were replaced with diesel engines. This was more efficient for users. The submarine soon becomes nuclear powered in 1955. We still use nuclear powered submarines.

A modern submarine
The submarine evolved quickly enabling people to travel underwater and float on water. Presently submarines have devices like periscopes, to help crew members see above the surface, sonars, to locate other vessels, submarines and torpedoes, and radars, to detect the location of items by measuring the time for which an echo of a radio wave takes to return.
