Turtle
The Turtle (also known as the American Turtle) was the first submarine to be used in combat. It was built in 1775 and used on September 6, 1776 in an unsuccessful attack against the HMS Eagle. It was invented by David Bushnell.
Wood was used to make the first submarine
H. L. Hunley was the name of the Confederate submarine that was used during the American Civil War. It was the first combat submarine to successfully sink an enemy ship.
Submarines are used both for military and rersearch purposes.
1776
Two military advances first used during WW1 were weapons and tactics.
The first submarine used for military purposes was built in 1776 by David Bushnell (1742-1824) of the US. His "Turtle" was a one-man, wooden submarine powered by hand-turned propellers. It was used during the American Revolution against British warships. The Turtle would approach enemy ships partially submerged to attach explosives to the ships's hull. The Turtle worked well but the explosives did not.
Cornelius Drebble created the first navigable submarine in 1620. It was named the Drebble, after him. At the time, nobody thought about the military potential of this device. The first submarine used in the military was named the Turtle. It was used during the American Revolutionary War. David Bushnell designed and created the Turtle. Shortly after, submarines became fairly common in the American Civil War used mainly by the very rich and powerful Union.
Techically, that would be the U.S. Navy's first submarine, USS S-1 (SS-105) , built by John Phillip Holland. Though the first submarine that was used in combat, David Bushnell's Turtle (Revolutionary War), the U.S. wasn't in fact a country at that time.The Confederate submarine H.L. Hunley was also not technically an American submarine, effectively being used by the Confederate Army (manned by Confederate sailors), but it was never a commissioned vessel in any navy.
This is an old and a common term. The torpedo has been used since the first submarine's were used in war time.
