Julius Hermann Kroehl (in German, Kröhl) (1820 – September 9, 1867) was a German American inventor and engineer. He invented and built the first submarine able to dive and resurface on its own, the Sub Marine Explorer, technically advanced for its era. His achievements in architecture, civil engineering, and mechanical engineering were also ...
A submarine (or sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) [2] The term “submarine” is also sometimes used historically or informally to refer to remotely operated vehicles and robots, or to medium-sized or smaller vessels (such as the midget submarine and the wet sub).
The Turtle was built in 1775 and was made to attach explosive charges to the hulls of the ships. Several attempts were made against British Ships in American harbors in 1776, but none were successful. Other submersible projects date to the 19th century. Alligator was a US Navy submarine that was never commissioned.
USS Alligator, the fourth United States Navy ship of that name, is the first known U.S. Navy submarine, and was active during the American Civil War (the first American underwater vehicle was Turtle during the Revolutionary War, and was operated by the Continental Army, vice Navy, in 1776 against British vessels in New York harbor).

Prototype "fleet submarines"—submarines fast enough (21 knots (11 m/s)) to travel with battleships. Twice the size of any concurrent or past U.S. submarine. A poor tandem engine design caused the boats to be decommissioned by 1923 and scrapped in 1930.
