First submarine3/14/2023 On the next page, read about the other developments in submarine design that emerged later in the 19th century. Hunley also fell victim to the explosion, and its entire crew died on Feb. Hunley used a long spar, or arm, to hold and release an explosive charge, successfully sinking the USS Housatonic. Hunley, a submarine used by the Confederacy during the Civil War, discovered this. If able to catch up to an enemy ship and attach explosives to it, escaping proved just as difficult. But the screw dislodged, separating the torpedo from its intended target. It was able to screw an appendage (a vertically aligned large screw to which a rope connected an explosive) into the hull of a British warship. Attaching explosives also proved tricky since it was difficult to penetrate the ships' hulls using screw-type devices.īy the War of 1812, a submarine similar to the Turtle had almost perfected this part. The first military submarine was Turtle in 1776, a hand-powered egg-shaped device. A 16th-century Islamic painting depicting Alexander the Great. Many submarines were simply unable to catch up to enemy warships. History of submarines Early history of submarines and the first submersibles. Though it may sound simple, the process was quite difficult. Early subs were usually propelled by hand-operated cranks, and their offensive strategies centered around covertly confronting a surface ship, attaching explosives to the enemy's hull and escaping before the explosion. Designing an underwater weapon delivery system proved to be a difficult task for years to come. The Turtle was used on July 7, 1776, to sneak up on a British battleship and attach an explosive device to the hull of the enemy ship. American inventor David Bushnell developed the first military submarine in 1775, during the American Revolution.
