Celebrate the Navy’s Birthday on October 13 and recognize the brave men and women who have served our country — past and present. Established during the Revolutionary War, the original Continental Navy was formed, disbanded, and then reestablished nearly 10 years later. Today it’s the largest and most capable navy in the world, with the highest combined battle fleet tonnage. The Navy also boasts the world’s largest aircraft carrier fleet, over 300,000 active personnel, and nearly 100,000 in the Ready Reserve.
