Established in 1933, this day commemorates the vital contributions of the maritime industry to the United States. It honors the historic voyage of the American steamship Savannah, marking the first successful transatlantic crossing with steam propulsion. The maritime industry is the backbone of our nation's military mobility, border security, and supply chain resilience. Its importance to America's prosperity and security is unmatched. The United States is, and always has been, a proud #MaritimeNation. #MaritimeHistory #MaritimeHeros #NationalMaritimeDay
