In the United States, subpoena history has long existed. David Bushnell designed America's first submarine, the Turtle, during the Revolutionary War period. The submersible made several attempts to sink British ships but never succeeded. The Turtle was not the Navy's first submarine at the time, at the time, the US Navy did not exist, so it was not the Navy's first submarine at the time, so it was not the Navy's first submarine. The USS Alligator was the first known US Navy submarine. It's also the fourth United States Navy ship of that name. During the American Civil War, the Alligator was present in the American Civil War.

Submarine Day is commemorated in Elsewhere in the world, on March 17th.
