The History of the United States Navy ratings spans more than 200 years of U.S. history from the United Colonies of the 1775 era to the current age of the 21st century United States Navy. Navy ratings in America were first created in 1775, during the American Revolutionary War, for use by the Continental Navy. After securing independence, the fledgling United States was without an operational Navy for nearly a decade. In 1797, the first three frigates of the United States were formally launched, bringing about new regulations concerning enlisted seaman ratings[1]
