The US Navy was founded on October 13, 1775 when the Second Continel Congress passed a resolution creating the Continental Navy.
Under President George Washington the Naval Act of 1794 created a permanent standing U.S. Navy which was created to fight the Barbary pirates of North Africa.
Six frigates were authorized as part of the Act. Over the next 20 years, the Navy fought the French Republic Navy (1798–99), Barbary states in the First and Second Barbary Wars and the British in the War of 1812.
Later the U.S. Navy fought in the Mexican–American War in 1846, and fought pirates in the Mediterranean and Caribbean seas, as well fighting the slave trade off the coast of West Africa.
In 1861 the U.S. Navy battled with the Confederate Confederate States Navy with both classic sailing ships and new ironclad ships.
After the Civil War, most of U.S. Navy’s ships were placed in reserve.
In the 1880s the U.S. Navy began a modernization program and served well in the 1898 war with Spain.
By the 1921 the U.S. Navy was equal in size to British Royal Navy.
During World War II the U.S. Navy supported the American Island Hopping campaign and ended up with over 1,600 ships.
Following the 1991 collapse of the Russian Navy the American Navy became the world’s undisputed naval super power.
