On October 6, 1866, the first U.S. Navy submarine, the 'Alligator', was launched in hopes of aiding the Union in the Civil War. Although the Alligator was not successful in operational missions, it represented a significant advance in naval technology.

The 'Alligator' was designed by a French engineer named Brutus de Villeroi and built at the Brooklyn Navy Yard. It was a wooden submersible shell significantly ahead of its time, able to carry explosives to enemy ships.

Although the 'Alligator' did not see active duty, it sparked interest in submarine technology, eventually leading to the development of better designs and further research in the 20th century. The Navy recognized the potential of underwater warfare thanks to this early attempt.

The launch of the 'Alligator' did not result in any successful missions, as the submarine sank during a trial run in 1863. Its very concept, however, paved the way for future innovations in submarine warfare.

Despite its failure, the 'Alligator' inspired other inventors and naval enthusiasts to pursue submarine technology, leading to designs that would culminate in successful submarines used during World War I.

The Alligator's design featured a hand-cranked propeller, which was an innovative feature but less effective compared to future developments in submarine propulsion.

Notably, the 'Alligator' was ahead of its time by decades, and it took another half-century before submarines became a viable component of naval strategy during World War I.

The legacy of the 'Alligator' continues to remind us of the innovations in marine warfare, influencing subsequent designs of effective submarines for the U.S. Navy today.
