In 1654, the Rotterdam boat submarine was invented with the intent to attack an enemy. In 1696, Denis Papin built two submarines with an internal air pump. In 1776, David Bushnell created the first submarine that attacked an enemy ship. In 1855, Wilhelm Bauer built the Diablo Marin which made 134 dives. In 1861 the U.S Navy commissioned the production of the Alligator submarine.
All submarines were built from steel. Except Bushnell's Turtle in 1776, that was made of wood & leather.
The first U-boats were built by Germany in 1904 for sale to the Russians during their war with Japan in 1904 (Russo-Japanese War 1904-1905).
