In his work, he describes the principles for making a boat sink or float. His prototype was a fully enclosed boat made of wood and surrounded by waterproof leather that could be submerged and rowed underwater. 1620-1624: Cornelius Drebbel built the first seaworthy submarine. When Drebbel worked for the English Royal Navy, he built a working submarine. boat based on Bourne's idea. His submarine was protected by greased leather and was piloted manually by 12 oarsmen. The submarine had an angled foredeck that pushed it underwater. Drebbel ended up making 2 more successful submarines between 1620 and 1624. His last one he presented to James I of England and many other Londoners. It was successfully submerged for 3 hours at a depth of 15 feet. 1690-1692: French physicist Denis Papin designed and built 2 improved submarines. Denis Papin based his submarine model on his invention of a pressure cooker. His first design was a heavy, solid metal box, fitted with a pump. Unfortunately, his design was destroyed before he could test it in the water. Papin's second drawing which he made 2 years later was different from the original. Its new design had an oval shape and featured a centrifugal air pump which was naturally resistant to external pressure because the pump allowed external air to freely enter and exit the hull. 1749: Giovanni Borelli had the idea of ​​modern ballast. .In 1749, Gentlemen's Magazine of London wrote an article about Borelli's boat which had been made in 1680 and covered with goatskins in the hull which allowed the boat to submerge. Borelli planned to submerge the ship by filling the skins with water and bringing it to the surface by driving the water away with a twisting rod. Although Giovanni Borelli's submarine was never built, it nevertheless constituted the first approach to modern ballast. 1776: David Bushnell creates the first military submarine “Turtle”.

He ensured that the United States Navy could attack British Royal Navy ships blockading New York Harbor during the American War of Independence. When Bushnell was studying at Yale, he proved that gunpowder could explode underwater and he also made the first time bomb. He then used these ideas to create a submarine capable of attaching explosives to the underside of British warships. Turtle was a single-seater, egg-shaped ship that resembled a turtle underwater. It submerged underwater, letting water enter the hull, and rose to the surface, pumping the water by hand. It consisted of 2 wooden hulls covered with tar and reinforced with steel strips. The Turtle was the submarine capable of independent underwater operations and movement and the first to use propellers for propulsion..
