After the Battle of Lexington and Concord, April 19, 1775, Bushnell began working on the project with New Haven’s wealthy inventor and fellow patriot, Isaac Doolittle (1721 – 1800). The pair assembled the earliest true submarine affectionately named the Turtle. But to do so required several firsts.
Bushnell's idea of using water as ballast for submerging and raising a submersible, considered simple and ingenious, is still in use to this day. So too the screw or two-blade propeller, as the name indicates to propel a vessel, was first crafted by Doolittle for the Turtle, which later revolutionized all steam and coal driven water craft. While a student at Yale, Bushnell was the first to demonstrate that gunpowder could explode underwater. Even more so, again with the help of Doolittle’s knowledge of brass and clock mechanics, was the first ever to construct a time-bomb; a clock-work mechanism that used a flint-lock sparking mechanism to explode water tight black powder. The plan was to attach the time bomb to the hull of a British man-of-war. Lastly, further expanding his knowledge of explosives, Bushnell became the father of ‘sea mines’, the first to use a firelock system, similar to the breech of a musket, to ignite water-tight black powder upon contact. They were called torpedoes as were all explosive water devises at that time...
The idea of exploding ships by the use of mines had been around since the 14th century. The Chinees floated wooden boxes laden with black powder. However, the explosive remained above water and could only be set off manually by tugging on a trigger mechanism attached by a long cord to either another vessel or on land. What could be called the first submarine was designed by Dutch engineer and inventor Cornelis Drebbel (1572-1633). By 1620, he had moved to England where he designed and built a wooden vessel that could be propelled underwater. This first submarine, though billed as such, did not fully submerge. Weighted down so a large portion remained underwater, it used sixteen surface oars to drive it up the Thames in London during its demonstration...
