Other than securing a place in history as the first submersible used in combat (Revolutionary War), David Bushnell's Turtle had absolutely no impact on society or naval warfare at all. It was never successful, and was destroyed by the British well before any improvements or changes could be made to increase its chances of sinking a British warship.
