In 1933, Congress declared National Maritime Day to commemorate the American steamship Savannah’s voyage from the United States to England, marking the first successful crossing of the Atlantic Ocean with steam propulsion.
The United States has always been and will always be a great maritime nation. From our origins as 13 British colonies, through every period of peace and conflict since, the Merchant Marine has been a pillar in this country’s foundation of prosperity and security. They power the world’s largest economy and strengthen our ties with trading partners around the world, all while supporting our military forces by shipping troops and supplies wherever they need to go.
