Submarine Service Flag

Submarines have a long history in the United States, beginning with Turtle, during the American Revolution. The world’s first combat submarine, invented by David Bushnell, was devised as a means of breaking the British blockade of Boston Harbor but was unsuccessful on multiple attempts.

The U.S. Navy officially joined the undersea world when it purchased USS Holland (SS-1) on 11 April 1900, and commissioned her on 12 October 1900. The boat, designed by John P. Holland, proved valuable for experimental purposes during her 10-year career. Since then submarines have evolved dramatically, but remain a vital part of the American fleet.
