History of the Holiday

National Submarine Day commemorates the anniversary of the first successful submarine voyage conducted by the American submarine, the USS Turtle, in 1776. Designed by David Bushnell, the Turtle was an early attempt to use underwater technology for warfare. While it was not entirely successful, it laid the groundwork for future advancements in submarine design. The day also celebrates the achievements of the U.S. Navy's submarine fleet throughout history, including the development of nuclear-powered submarines during the Cold War. The holiday serves as a reminder of the evolution of submarine technology and the critical role submarines have played in defense and exploration.
